The first of my easy, no-bake biscuit slices.
Tip: The quality of the chocolate really matters here - if you use cheap chocolate, they'll taste like cheap chocolate.
Chocolate Peanut Biscuit Slice
Makes 16 large or 32 party portions
Prep 30 mins plus cooling
Ingredients:
For the base:
250g butter
200g dark chocolate, chopped. Please do use dark - it is mixed with other ingredients so doesn't taste dark! Milk chocolate will be too sweet.
500g digestive biscuits
For the filling & topping:
250g smooth peanut butter
100g chopped salted peanuts
For the ganache:
200g dark chocolate, 54% cocoa solids works best. In chips, callets or chopped.
100ml double cream
Method:
Line a 30 x 20cm baking sheet with baking paper.
Smash the biscuit to fine crumbs in a food processor, or in a sealed freezer bag with a rolling pin.
Melt together 200g dark chocolate and the butter. If you do this in the microwave, keep on taking the bowl out and giving it a stir to prevent hot spots that will burn the chocolate. You can also melt in a steel bowl - put an inch of water in a large pan, bring to the boil, turn down to low and set the pan on top. Keep stirring every few minutes as it melts. Don't overheat - remove from the heat when there are still a few small lumps and keep stirring.
Mix into the biscuit crumbs while still hot, and pour onto the baking sheet. Spread out evenly and press down firmly with a spoon, or the smooth bottom of a glass tumbler. Chill to set while you make the ganache.
To make the ganache, heat the cream to boiling point. Remove from the heat, leave to cool for a few minutes, then stir in the dark chocolate until it melts. Leave to cool.
Spread the peanut butter evenly over the base. Chill to firm.
Spread the almost cooled ganache evenly over the top of the peanut butter. Handle this very lightly so you don't pull up the PB.
Sprinkle with the chopped salted peanuts.
Leave to cool completely - no need to refrigerate as this can cause condensation.
Cut into slices or squares to suit the size you need. Serve with a posh coffee. These will keep for approx a week if stored airtight in a cool, dry place.
