Ingredients
- 200 g, crushed digestive biscuits
- 100 g, melted unsalted butter
- 200 g smooth peanut butter
- 150 g icing sugar
- 200 g, chopped dark chocolate
- 395 g (1 can) sweetened condensed milk
- 1 tsp vanilla extract
Instructions
- Step 1: Combine 200 g crushed digestive biscuits and 100 g melted unsalted butter in a bowl, stirring until the mixture resembles wet sand. Press this evenly into the base of a 9-inch square baking pan lined with parchment paper and refrigerate for 15 minutes to set.
- Step 2: In a separate bowl, mix 200 g smooth peanut butter, 150 g icing sugar, 395 g sweetened condensed milk, and 1 tsp vanilla extract until smooth and creamy. Spread this peanut butter mixture evenly over the chilled biscuit base.
- Step 3: Melt 200 g chopped dark chocolate in a heatproof bowl over simmering water, stirring until smooth and glossy. Pour the melted chocolate over the peanut butter layer and smooth the top with a spatula. Refrigerate the slice for at least 3 hours or until fully set before slicing into squares.
