Full list of worst price increases in supermarkets as items rise by up to 115%
The supermarket products that have risen in price by as much as 115% have been revealed by Which? magazine.
Which? tracked prices at eight major supermarkets - including Aldi, Asda, Tesco, Morrisons, Sainsbury's, Lidl, Ocado and Waitrose - to highlight the largest price increases in the year to May 2025.
The biggest increase was Sainsbury's Sainsbury's No Added Sugar Dark Chocolate, which jumped in price by 115% from £1.25 to £2.68.
Tesco shoppers saw the price of Galaxy Chocolate Sponge Cake Bars with Cream Centre and Maltesers Cake Bars rise by 85% from £1.49 to £2.75.
Meanwhile, Morrisons Savers Milk Chocolate went up 71% from 47p to 80p and Lidl Vemondo Soya Drink Unsweetened rose 68% from 51p to 85p.
While products normally come with a recommended retail price (RRP) it is ultimately down to retailers to decide how much they want to charge. You can see the worst price rises flagged by Which? in the list below.
Which? analysed the prices of 27,000 products across 20 food and drink categories. Its data shows the price of chocolate has risen by 17.5% in the last year, while biscuits are up 10.1% and butters and spreads have increase by 9.4%
The Mirror has contacted all the supermarkets included in the Which? report for comment.
Reena Sewraz, Which? Retail Editor, said: 'It's always worrying when we see supermarket food prices going up because we know this will have a big impact on hard-pressed households who already spend a larger chunk of their budget on groceries.
'Our research shows that shopping at Aldi or Lidl if you have local branches and buying own-brand products are the surest way to keep down the cost of the weekly shop.'

How to save money in the supermarkets
Try swapping more expensive branded goods for cheaper supermarket-own labels - this is also known as the 'Downshift' challenge and it is estimated you could save around 30% on your food bill. Next, don't just stick to one aisle in the supermarket.
Make sure you compare prices at and shop around to find the best deals. But avoid shopping at your local convenience store if you can, as these are always more expensive than going to a big shop. Another tip, is to find cheaper versions of the same products in the world foods and baby sections.
Finally, keep an eye out for those yellow sticker deals - not only will they save you money, but you also help cut down on food waste. We've got more supermarket tips to save you money here.
