Mint Chocolate Fridge Cake, or tiffin, makes a decadent departure from the classic no-bake chocolate cake. This rich, fudgy cake is loaded with chocolate, butter, biscuits and mint chocolate treats. Utter bliss.
Normally around April, I tell you all about my baking exploits during late March when my children have their birthdays plus a party each and I end up baking my body weight in cakes. Well, this year, things were a little different. There was still plenty of cake, one of which will make it’s way onto here before too long. But the star of the birthday season this year was a baking party. That was 4 girls who’ve been friends since they were 5 taking over my kitchen for numerous hours. Between them, they baked enough sweet goods to stock a coffee shop. I stayed out out the way until it was time to sample their bakes and er…. tidy up.
Nestled amongst cookies, muffins, bourbon biscuits, cornflake clusters and flapjack was a chocolate refrigerator cake. Oh my. I can’t recall the last time I ate a piece of chocolate fridge cake, but it was good. So good, in fact, that it got my mind racing. And, whenever chocolate is involved my mind always speedways itself straight to mint.
I’m a kid in disguise really.
Several weeks later and I was ready to trial my notion. A straight chocolate fridge cake includes chocolate, butter and biscuits. Sometimes a little honeycomb might find it’s way into the mix, or some dried fruit and nuts. But I wanted my Mint Chocolate Fridge Cake to have a mighty minty bite. So I went all out. I’ve got two types of mint biscuits in here along with two varieties of mint chocolate.
My blend includes:
- Viscount biscuits – a plain biscuit with a peppermint cream top all smothered in chocolate
- Mint Oreos – a green peppermint cream sandwiched between dark chocolate cookies
- Fry’s Peppermint Cream – powerful white peppermint fondant laced in dark chocolate
- Mint Aero Bubbles – sweet, bright and very green
I chose this mix for the minty flavours, variation in shapes and different colours. I know that these products are not all available worldwide, but I’m hoping you’ll be able to lay your hands on similar products. Just make like for like substitutions – biscuit for biscuit and chocolate for chocolate in the same weights. Here are a few suggestions that should make good alternatives:
- Ghirardelli Dark Chocolate Mint Squares
- DOVE Dark Chocolate Mint Swirl Candy Bar
- Nestle Aero Mint Chocolate Bar
- Andes Candy Creme de Menthe
- York Peppermint Patties
- After Eight Mints
If you can get hold of mint Aero – either balls or bar – do get them – the colour and bubbly texture really do add something to this Mint Chocolate Fridge Cake.
I know it’s tempting to run off to the supermarket, scoop your stash of minty goodies and get mixing, but I’ve got a big piece of advice to serve up before you make a start. You must respect your ingredients. A lot of these minty treats will not stand up to being mixed ferociously and some do not even like heat (lovely, bubble Aero balls, I’m looking directly at you). Here are my tips for success:
- Stir the chopped biscuits into the warm chocolate mix only briefly – 4 or 5 turns is sufficient
- Do not stir the any of the chocolates directly into the warm chocolate mix – they will melt too much and loose their shape
- Instead, layer this cake up gradually, sprinkling the chocolate into the mix as you layer it up
That’s my advice. Something told me that the Aero Bubbles would rebel and end up in little green piles if I even thought about mixing them directly in. It only takes a few more minutes to layer this cake up gradually in a tin and it’s well worth that extra effort to retain those bubbly green balls.
Once set this Mint Chocolate Fridge Cake can be sliced into small squares (or large bars) and pulled out of the fridge as and when required (24/7 in my case).
Each slice of Mint Chocolate Fridge Cake delivers exactly what you would expect – rich, fudgy, chocolatey bites of bliss loaded with crunchy biscuits and intense bursts of peppermint. Immensely and intensely fun. Just what my 5 year old self would have been hankering after.

Mint Chocolate Fridge Cake
- 100 g/ 3/5 oz Butter
- 300 g/ 10 1.2 oz Dark Chocolate (around 60% is fine)
- 1 tbsp Golden syrup (light corn syrup)
- 1 Egg
- 160 g/ 5 1/2 oz Mint biscuits (I used 6 Viscounts & 6 Mint Oreo biscuits)
- 100 g/ 3 1/2 Fry's Peppermint Creams (or other mint fondant cream in dark chocolate)
- 80 g/ 3 oz Mint Aero Bubbles (or other Mint chocolate)
- Grease a small loaf tin (1kg) and line it neatly with baking parchment
- Put the butter, dark chocolate and syrup into a medium heatproof mixing bowl and suspend over a pan of barely simmering water (ensure the water does not touch the bottom of the bowl). Stir until melted
- Crack the egg into a jug, whisk briefly and stir into the chocolate batter. Remove the bowl from the heat and let cool for 15 minutes, stirring once or twice
- Meanwhile break the biscuits into chunks (6-8 per biscuit) - scoop all the chunks and crumbs into a bowl
- Chop the peppermint creams into pieces but leave the Aero Bubbles intact
- When ready, tip the biscuit pieces into the chocolate batter and briefly stir with a large metal spoon to combine - 4 or 5 turns should be sufficient
- DO NOT MIX THE PEPPERMINT CREAM CHOCOLATE OR THE AREO BUBBLES INTO THIS BATTER (sorry to shout but this is really important)
- Spoon 1/4 of this mix into the base of the loaf tin, ensuring the mix reaches the corners of the tin
- Spread 1/3 of the peppermint cream chunks and 1/3 of the Aero Bubbles over the base and top with another 1/4 of the chocolate batter. Take care to ensure that the batter reaches the corner and the layer of peppermint chocolates are covered - use the back of a small metal spoon to guide the mix into empty spaces
- Repeat with another 1/3 of the peppermint creams and Aero Bubbles and top with another 1/4 of chocolate batter
- Spread the remaining mint chocolates on the top and cover completely with the final 1/4 of the batter. Carefully level using the back of a metal spoon
- Wrap the tin in clingfilm and transfer to the fridge for around 6 hours to set
- When ready, carefully remove from the loaf tin, remove the parchment and cut into 10-12 slices
- Store in the fridge for up to 1 week. Remove from fridge 15 minutes before serving
