How to make No Bake Biscoff Caramel Slice
Prepare the base:
- Line a rectangular baking tin (approx. 24cmx13cm) with baking paper.
- Crush Biscoff biscuits into fine crumbs using a food processor (or place in a ziplock bag and crush with a rolling pin). Mix with melted butter until well combined.
- Press the mixture firmly into the base of the tin and leave in the fridge while you make the caramel.
Make the caramel layer:
- In a small saucepan, combine the condensed milk, brown sugar, butter and Biscoff spread.
- Stir continuously over medium heat for 5–7 minutes until the mixture thickens.
- Pour the caramel over the base and smooth it out. Leave in the fridge for 20 minutes before adding the chocolate.
Top with chocolate:
- Melt the chocolate and Biscoff spread together in the microwave. Pour over the caramel and spread evenly. Drizzle extra Biscoff spread on top and swirl with knife – microwave it for 10–15 seconds to make it runny.
- Leave in the fridge for 4-5 hours for the caramel and chocolate to set.
Slice and serve:
- Once set, remove from the tin, cut into 10 pieces using a hot knife (to prevent the chocolate from cracking).
- Enjoy – store in an airtight container in the fridge.
