What You'll Need To Make Marble Cake
Jennifer Segal
Chocolate: I use a mix of natural cocoa powder and semisweet chocolate to create the chocolate swirl. The cocoa powder brings rich, intense flavor, while the semisweet chocolate makes the ribbons even deeper and more chocolatey.
Sugar: Sweetens both the cake and the glaze and contributes to the tender texture of the crumb.
Buttermilk: Adds moisture and gives the cake a soft, tender crumb. Its acidity is what makes it different from regular milk. No buttermilk? Just add 1 tablespoon of lemon juice or vinegar to a 1-cup measuring cup, fill it the rest of the way with milk, and let it sit for 5 minutes before using.
Eggs and Flour: Our baking basics which provide structure for the cake.
Vanilla Extract: Brings warmth and depth to both the cake and glaze.
Baking Powder and Baking Soda: Work together to give the cake lift and ensure a light texture.
Unsalted Butter: Adds richness and flavor to both the cake and the glaze.
How to Make Homemade Marble Cake
Grab all your ingredients, grease your Bundt pan, and preheat your oven to 325 degrees F (165 degrees C) so it's ready for baking the marble cake as soon as you've got it ready to go.
Step 1: Make the chocolate base. Combine the cocoa powder, a half cup of the sugar, and the water in a small saucepan. Bring to a simmer over high heat, whisking it together until the mixture is smooth. Remove the cocoa mixture from the heat and immediately add the chocolate. Whisk the mixture until the chocolate is melted and it's smooth.

Step 7: Assemble and swirl the cake layers. Spoon half of the vanilla batter into a greased Bundt pan. Pour the chocolate batter over the top. Spoon the remaining vanilla batter over the top of the chocolate. Use a butter knife or skewer to swirl the batters together with a zig-zag motion, going three times around the pan. Bake for 60 to 70 minutes, until a cake tester comes out clean.

Step 8: Make the glaze. While the cake bakes, make the glaze by boiling butter, sugar, water, and vanilla, then simmering until the sugar dissolves.
Jennifer Segal
Step 9: Glaze the cake and cool. Remove the cake from the oven when it's ready. Use a skewer or toothpick to poke about 40 holes in the bottom of the cake. Brush half of the glaze evenly over the bottom of the cake. Leave the cake on the rack to cool for 30 minutes.

Jenn's Pro Tips for the Best Marble Cake
Making the Swirls. Be careful not to over-swirl the batters or the flavors will get muddled. All it takes is a few turns around the pan with a knife to do the trick.
Greasing Your Pan. Make sure to fully grease your bundt pan, including all the cracks and crevices. Baking spray makes this really easy to do!
Do Not Over-bake. Your bundt marble cake is done when you insert a toothpick or other cake tester into the center of the cake and it comes out clean.

Marble Cake
Makes one 10-inch Bundt Cake
Prep Time: 30 Minutes
Cook Time: 60 Minutes
Total Time: 1 Hour 30 Minutes, plus a few hours to cool
For the Cake
1/2 cup natural cocoa powder, such as Hershey's
2 1/2 cups sugar, divided
1/2 cup water
4 ounce semi-sweet chocolate, best quality such as Ghirardelli, broken into 1-in pieces
1 cup buttermilk (see note)
4 large eggs
2 teaspoons vanilla extract
3 cups all-purpose flour, spooned into measuring cup and leveled-off
1 teaspoon baking powder
1/2 teaspoon baking soda
3/4 teaspoon salt
1 cup (2 sticks) unsalted butter, softened
For the Glaze
5 tablespoons unsalted butter
3/4 cup sugar
1/4 cup water
2 teaspoons vanilla extract
Preheat the oven to 325 degree F and set an oven rack in the middle position. Spray a 10-in (12-cup) Bundt pan generously with nonstick cooking spray with flour, such as Baker's Joy or Pam with Flour.
In a small saucepan, combine the cocoa powder, 1/2 cup of the sugar, and the water. Bring to a simmer over high heat, whisking until smooth. Off the heat, immediately add the chocolate; whisk until the chocolate is melted and the mixture is smooth. Set aside.
In a medium bowl, whisk together the buttermilk, eggs, and vanilla. Set aside. (Note that the mixture will start to look curdled as it sits; that's okay.)
In the bowl of an electric mixer fitted with the paddle attachment or beaters, combine the flour, baking powder, baking soda, salt, and remaining 2 cups of sugar. Beat on low speed for 30 seconds to combine. Add the softened butter and half of the buttermilk mixture and mix on low speed until moistened but still a little crumbly, about 1 minute. With the mixer running on low, gradually add the remaining buttermilk mixture until incorporated, then increase the speed to medium and mix for three minutes, stopping once to scrape down the sides and bottom of the bowl with a rubber spatula. The batter should look pale and creamy. Scrape down the sides and bottom of the bowl again, making sure the batter is evenly mixed.
Transfer about 2 1/2 cups of the batter to a medium bowl. Add the chocolate mixture and whisk until smooth.
Spoon half of the remaining vanilla batter into the prepared Bundt pan. Pour the chocolate batter over top. Finish by spooning the remaining vanilla batter over the chocolate (don't worry about covering the chocolate layer completely). Using a butter knife, swirl the batters together with a zig-zag motion, going three times around the pan. It may not look like the batters are swirled; that's okay. It's important not to over-swirl.
Bake for 60 to 70 minutes, or until a cake tester comes out clean.
While the cake bakes, make the glaze: In a small saucepan, combine the butter, sugar, water, and vanilla. Bring to a boil, then reduce the heat and simmer until the sugar is dissolved, about 1 minute.
Set the pan on a cooling rack. Using a skewer or toothpick, poke about 40 holes in the bottom of the still-hot cake, going about 3/4 of the way down. Spoon or brush half of the glaze evenly over the bottom of the cake. If the glaze starts to pool on the surface, poke more holes to help it absorb. Leave the cake on the rack to cool for 30 minutes.
Invert the cake onto a serving platter. Brush the remaining glaze evenly over the top and sides of the cake, letting it soak in as you go. (Go slowly so that the glaze gets absorbed.) Let the cake sit for at least two hours before serving. Cut with a serrated knife.

Comment By UN Human Rights Office Spokesperson Seif Magango On Deadly Drone Strikes In North Darfur, Sudan
4 June 2025 The deadly aerial strike this week on a UN humanitarian convoy in Al Koma, North Darfur, clearly undermines access by civilians to assistance and violates the international humanitarian law prohibition of attacks against humanitarian personnel and objects. Monday's attack launched from an unmanned aerial vehicle (UAV), which claimed the lives of five members of the convoy, dealt a severe blow to civilians in the besieged city of El Fasher who were waiting to receive critical food and nutrition supplies amid a rapidly deteriorating humanitarian situation. Another UAV strike, reportedly attributed to the Sudanese Armed Forces (SAF) earlier this week, struck a busy market in Al Koma, killing at least 15 civilians and injuring dozens more. This incident comes amidst reports of similar attacks by both parties to the conflict targeting civilian objects, including markets. We urge all parties to the conflict to take prompt and concrete measures to protect civilians and civilian objects, and to facilitate safe and unimpeded humanitarian assistance, in line with their obligations under international humanitarian law. We call for prompt and impartial investigations into both attacks and meaningful steps to bring those responsible to justice.

Neural Networks Speed Up Search For Solid-State Battery Materials For Safer Electric Cars With Extended Range
Press Release – Skoltech So far solid-state batteries have not been adopted by carmakers, but EV developers are looking to capitalize on the technology before competitors. The new type of energy storage could improve fire safety and boost EV range by up to 50%. Researchers from Skoltech and AIRI Institute have shown how machine learning can speed up the development of new materials for solid-state lithium-ion batteries. These are an emerging energy storage technology, which could theoretically replace conventional Li-ion batteries in electric vehicles and portable electronics, reducing fire hazards and extending battery life. In the Russian Science Foundation-backed study, published in npj Computational Materials, neural networks proved capable of identifying promising materials for the key component of these advanced batteries — the solid electrolyte — as well as for its protective coatings. Like its conventional counterpart, the solid-state battery incorporates an electrolyte, through which ions carrying the electric charge travel from one electrode to another. While in a conventional battery the electrolyte is a liquid solution, its solid-state analogue, as the name suggests, relies on solid electrolytes, such as ceramics, to conduct lithium ions. So far solid-state batteries have not been adopted by carmakers, but EV developers are looking to capitalize on the technology before competitors. The new type of energy storage could improve fire safety and boost EV range by up to 50%. The problem is that none of the currently available solid electrolytes meets all the technical requirements. So the search for new materials continues. 'We demonstrated that graph neural networks can identify new solid-state battery materials with high ionic mobility and do it orders of magnitude faster than traditional quantum chemistry methods. This could speed up the development of new battery materials, as we showed by predicting a number of protective coatings for solid-state battery electrolytes,' commented the lead author of the study, Artem Dembitskiy, a PhD student of Skoltech's Materials Science and Engineering program, a research intern at Skoltech Energy, and a junior research scientist at AIRI Institute. Study co-author, Assistant Professor Dmitry Aksyonov from Skoltech Energy explained the role of protective coatings: 'The metallic lithium of the anode is a strong reducing agent, so almost all existing electrolytes undergo reduction in contact with it. The cathode material is a strong oxidizing agent. When oxidized or reduced, electrolytes lose their structural integrity, which can degrade performance or even cause a short circuit. You can avoid this by introducing two protective coatings that are stable in contact with the anode and the electrolyte and the cathode and the electrolyte.' Machine learning algorithms make it possible to accelerate the calculation of ionic conductivity, a key property both for electrolytes and for protective coatings. It is among the most computationally challenging characteristics calculated in screening the candidate materials. For protective coatings, the list of properties that are checked at various stages of material selection includes thermodynamic stability, electronic conductivity, electrochemical stability, compatibility with electrode and electrolyte materials, ionic conductivity, and so on. Such screening happens in stages and gradually narrows down the list of perhaps tens of thousands of initial options to just a few materials. The authors of the study used their machine learning-accelerated approach to search for coating materials to protect one of the most promising solid-state battery electrolytes: Li10GeP2S12. The search identified multiple promising coating materials, among them the compounds Li3AlF6 and Li2ZnCl4.

Stigmatised For Being Deaf: Zénabou's Story
Press Release – UN News In the Central African Republic, disability carries a deep-rooted stigma, and persons with disabilities often find themselves excluded from almost every avenue of life. Znabou, who is deaf and non-speaking, has suffered from prejudice, but a UN-backed … 7 June 2025 'I always had the painful experience of seeing the other children go to school with their rucksacks,' says 14-year-old Zénabou. 'It was tormenting because even though I was burning with a desire to find out what happened in the schools where these children went every morning, I realised very early on that it was a system that wasn't made for me because I was different.' For many children with disabilities, the doors to education have remained firmly shut, leaving them with few opportunities and little hope for the future. Yet, in the Central African Republic (CAR) today, children like Zénabou are finally receiving the adapted support and educational opportunities that they deserve thanks to a new inclusive education pilot initiative. The programme is providing essential resources like learning materials, mobility aids, and specialized classes to learn Braille and sign language; creating a network of community support for families; and integrating children with disabilities into local schools. A Door Opens Zénabou sits at the desk in her classroom, workbook in front of her, and surrounded by classmates. She smiles as she watches her teacher write something on the blackboard. It might look like an ordinary scene to someone passing by but to the fourteen-year-old and other children with disabilities like her, this is an extraordinary moment. Before she enrolled in classes, Zénabou would stay at home most of the day, helping her mom with household chores. Her hours were filled with washing dishes, cleaning clothes and fetching water for her family. 'Going to school was something I'd never hoped for,' she signs. 'The day I went to school for the first time, I suddenly realised that I wasn't the only one in this situation. Seeing more than 30 deaf people in the same place was astonishing!' Through a multi-year investment, specialised classes for deaf and visually impaired children are held in Bambari, CAR, within ordinary primary schools. There, children like Zénabou who have often never even stepped foot in school are taught to read, write and count, and learn Braille or sign language. These crucial skills unlock a world of learning for them. Before attending school, Zénabou could barely communicate with those around her. Her parents saw few opportunities for her future. Illiterate themselves, they wanted more for their daughter, but considering her disability, they had no hope. But everything changed when she was given the access, resources and support to learn. 'My daughter Zénabou is now able to assert herself as a person, despite the communication barriers caused by the fact that she is deaf,' says Zénabou's Father. 'I'm now optimistic about Zénabou's future and I know she's going to succeed!' Education Crisis in CAR The Central African Republic is one of the toughest places in the world to be a child. Conflict, displacement and instability are undermining efforts for peaceful development, putting children and adolescents at serious risk. Years of violence have contributed to the breakdown of what were already limited services. Access to healthcare, livelihood opportunities and education is very limited or non-existent in large parts of the country. The country's education system is grappling with significant challenges, particularly for children with disabilities. Prolonged conflicts have devastated the educational infrastructure, leaving a million children and adolescents out of school. This crisis disproportionately affects children with disabilities, who face compounded barriers to education due to stigma surrounding disabilities and limited access to specialized support. Addressing these challenges requires concerted efforts to rebuild educational infrastructure, promote inclusive teaching practices, and combat societal stigma to ensure that all children have access to an inclusive, quality education. Inclusive education in the Central African Republic Working with organizations that represent persons with disabilities is key to ensuring their participation in decision-making, as outlined in the Convention on the Rights of Persons with Disabilities. It has also been recognized to be necessary for social change, to promote autonomy and to ensure the empowerment of persons with disabilities. This groundbreaking initiative is funded by Education Cannot Wait (ECW), the global fund for education in emergencies and protracted crises in the United Nations It is supported by the UN children's agency UNICEF, partners like Humanity and Inclusion and national organizations, including the Centre d'Alphabétisation et de Formation en Braille pour les Aveugles en Centrafrique' and the Association Nationale des Déficients Auditifs de Centrafrique.
