Ingredients
Makes 1 loaf (about 10–12 slices)
- 10 oz (280g) plain tea biscuits or digestive biscuits
- 1/2 cup (115g) unsalted butter
- 1/2 cup (120ml) milk (or almond milk)
- 1/2 cup (100g) granulated sugar (or honey/maple syrup)
- 1/3 cup (35g) unsweetened cocoa powder
- 6 oz (170g) dark chocolate, chopped (or semi-sweet)
- 1 teaspoon vanilla extract
- Pinch of salt
Optional Add-Ins
- 1/3 cup chopped nuts (walnuts, almonds, hazelnuts)
- 1/3 cup mini marshmallows
- 1/3 cup raisins or dried cranberries
- 2 tablespoons peanut butter (for extra richness)
Preparation Time
- Prep time: 15 minutes
- Chill time: 4 hours (or overnight)
- Total time: About 4 hours 15 minutes
Step-by-Step Instructions
Step 1: Break the Biscuits
Place biscuits in a large bowl and break them into bite-size chunks. Don’t crush them into crumbs—you want texture.
Step 2: Make the Chocolate Mixture
In a saucepan over low heat, melt butter, milk, and sugar together. Whisk in cocoa powder and salt until smooth.
Step 3: Melt in the Chocolate
Remove from heat and add chopped chocolate. Stir until fully melted and glossy. Mix in vanilla extract.
Step 4: Combine
Pour the warm chocolate mixture over the biscuit pieces. Add any optional add-ins. Stir gently until everything is evenly coated.
Step 5: Shape
Line a loaf pan with parchment paper (or lightly grease). Press the mixture firmly into the pan, packing it down so it holds together.
Step 6: Chill
Refrigerate for at least 4 hours (overnight is best) until firm.
Step 7: Slice and Serve
Lift out using parchment, slice into pieces, and serve chilled or slightly softened at room temperature.
Serving Suggestions
- Dust the top with cocoa powder or powdered sugar before slicing.
- Drizzle with melted chocolate for a bakery-style finish.
- Serve with fresh berries for a bright contrast.
- Pair with coffee or tea for the perfect afternoon treat.
- Add a scoop of vanilla ice cream for an extra indulgent dessert.
