My easy, no-bake biscuit slices all start with the same crushed biscuit base, topped with the same layer of indulgent chocolate ganache.
You can vary the toppings with whatever you have in the cupboard.
Terry's Chocolate Orange taste like Christmas to me. It's a proper treat in our house. Try to buy them when they're on special offer!
Tip: The quality of the chocolate in the ganache really matters here - if you use cheap chocolate, they'll taste like cheap chocolate.
Chocolate Orange No-Bake Biscuit Slice
Makes 16- 32
Prep 30 mins plus cooling
Ingredients:
For the base:
250g butter
200g dark chocolate, chopped (please do use dark, even if it's only a 54% cocoa solids one - it is mixed with other ingredients so doesn't taste dark! Milk chocolate will be too sweet.)
500g digestive biscuits
For the topping:
2 x Terry's Chocolate Oranges, split into segments
Whatever chocolatey or festive sprinkles you have to hand, and maybe some dark or white chocolate to melt and drizzle
For the ganache:
200g dark chocolate, 54% cocoa solids works best. In chips, callets or chopped.
100ml double cream
1/2 a tsp orange extract - I love the Nielsen Massey one
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. Don't overheat it.
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 making 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. Stir in the orange extract. Leave to cool.
Spread the almost cooled ganache evenly over the chilled biscuit base.
Top with the chocolate orange segments, and add the sprinkles and melted chocolate drizzle if you have them.
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.
