What You’ll Need
This recipe is beginner-friendly and requires only a few basic kitchen tools.
Kitchen Tools
- Microwave-safe bowl or double boiler
- Large mixing bowl
- Small loaf tin or baking tin
- Baking paper
- Spatula
Ingredients
- 300g dark chocolate (70% preferable)
- 100g butter
- 100g condensed milk
- 1 tsp vanilla extract
- 200g tennis biscuits
- 3 x 49g Peppermint Crisp chocolate bars (broken into chunks)
- 1 tsp sea salt flakes
- 1 x 49g Peppermint Crisp chocolate bar (for decoration)
Instructions

- Prepare the Tin:
Line a small loaf tin or baking tin with baking paper, leaving the edges hanging over the sides to make unmolding easier. - Melt the Chocolate Mixture:
In a microwave-safe bowl, combine the dark chocolate, butter, condensed milk, and vanilla extract. Microwave on medium to low heat in 30-second bursts, stirring in between, until smooth and glossy. Alternatively, you can melt the mixture using the double boiler method. - Cool the Mixture:
Let the chocolate mixture stand for a few minutes to cool slightly. - Prepare the Biscuit Mixture:
In a large mixing bowl, break the tennis biscuits into bite-sized pieces. Break the Peppermint Crisp bars into chunks and add them to the bowl. - Combine and Mix:
Pour the cooled chocolate mixture over the biscuit and Peppermint Crisp mixture. Add the sea salt and stir until just combined. Be careful not to overmix, as you want to keep the biscuit pieces intact. - Set the Cake:
Pour the mixture into the prepared tin, spreading it evenly with a spatula. Place it in the fridge and let it chill until completely set (about 2–3 hours). - Decorate and Slice:
Once set, unmold the cake and let it sit at room temperature for 10 minutes. Decorate with the extra Peppermint Crisp bar, breaking it into chunks and sprinkling it over the top. Slice into even pieces and serve.

FAQs about Peppermint Crisp Biscuit Cake
1. Can I make Peppermint Crisp Biscuit Cake ahead of time?
Yes! This cake sets beautifully in the fridge, so you can make it up to two days in advance. Just store it in an airtight container.
2. What can I use if I don’t have Peppermint Crisp?
If you can’t find Peppermint Crisp, use mint-flavored Aero or mint chocolate chips as a substitute. The minty flavor is key to the cake’s signature taste.
3. Can I use milk chocolate instead of dark chocolate?
Yes, but the cake will be sweeter. If you prefer a less intense flavor, milk chocolate works well.
4. How do I prevent the cake from becoming too hard in the fridge?
If the cake sets too firmly, let it sit at room temperature for 10–15 minutes before slicing. This softens the chocolate slightly, making it easier to cut.
