I still remember the first time I tried a chocolate fridge cake recipe. My granny made it with crushed biscuits, fruit bits, and some marshmallows tossed in. It was cold, crunchy, and oh-so-good. I had no idea then that this was Prince William’s favourite cake, or that he chose it for his royal wedding over a fancy, tiered one! Chef Darren McGrady even said it was a favorite of Queen Elizabeth II and Princess Diana. This cake isn’t just delicious’s got some serious royal history behind it.
The best part? You don’t even need an oven. No baking, no stress. Just melt, mix, and chill. It’s great for teaching basic cooking skills to kids, or for days when you want a treat without the hassle. Grab what you’ve got- cereal, honeycomb chunks, or even dried fruit- and toss it all in. The mix-ins are endless, and that’s what makes every batch unique.
What makes it so addictive is the texture. It’s crispy, a little chewy, and completely satisfying. I’ve brought this cake to company picnics, school bake sales, and even summer potlucks. It disappears fast. And whether it’s afternoon tea or just a midnight snack, a chilled slice always hits the spot. No matter the season, it’s a crowd-pleaser.
Want to take it to the next level? Cut it into bars, layer it with ice cream, or drop cubes into a sundae. One time I brought a batch to school, and my friends said it was the best thing ever. It’s part cake, part candy bar, and 100% easy. You barely need effort, but people always ask for the recipe. It’s a win-win dessert-fridge-friendly, creative, and made for sharing.
Why Everyone Loves Chocolate Fridge Cake
Let’s start with what makes this treat so loved and so unique.
🍫 What is Chocolate Fridge Cake?
Chocolate fridge cake is a no-bake dessert made by mixing crushed biscuits with melted chocolate, butter, and syrup, then chilling it until firm. It’s sometimes called a “tiffin” in the UK.
It’s not a cake. There’s no sponge. No flour. But it looks like a cake when sliced, and it tastes like heaven.
🏰 A Cake Fit for Royalty
Prince William chose a chocolate fridge cake as his groom’s cake for his royal wedding to Kate Middleton. Made by McVitie’s using a special royal recipe, it was filled with Rich Tea biscuits, chocolate, and lots of memories.
“It was a childhood favorite. The Queen loved it. Diana loved it. And William still does.” – Chef Darren McGrady, former Royal Chef.
This isn’t just any dessert- it’s a slice of history.

FAQs
How long does chocolate fridge cake last?
Chocolate fridge cake lasts up to 7 days in the fridge, tightly wrapped. You can also freeze it for up to 3 months. Just defrost it in the fridge before serving. It keeps well because no dairy or egg spoils fast.
Can I freeze chocolate fridge cake?
Yes! Slice it into portions and wrap each piece in plastic wrap and foil. Store in an airtight container for up to 3 months. When you want a slice, just thaw it in the fridge overnight for the best texture.
Is chocolate fridge cake gluten-free?
It can be! Just use gluten-free biscuits and check your chocolate and add-ins to make sure they’re certified gluten-free. Many brands now offer safe options, making it easy to enjoy without gluten.
Can I make chocolate fridge cake with white chocolate?
Absolutely. White chocolate gives a sweeter and creamier result. Just make sure to balance it with crunchy mix-ins like pretzels or nuts, since white chocolate can be very rich. A pinch of salt helps, too!
Why is my fridge cake too soft or not setting?
It’s usually because of too much syrup or butter, or not enough chilling time. Always chill for at least 4 hours- overnight is best. And use real chocolate, not chips, for proper setting power.
