Instructions
For the Hot Chocolate Slice:
1. Prepare the Base:
In a large bowl, mix the crushed graham crackers (or digestive biscuits) with the melted butter until the crumbs are fully coated. Press this mixture into the base of a greased 8×8-inch square pan (or similar-sized dish), making sure it’s evenly distributed. Set aside.
2. Make the Fudgy Chocolate Layer:
In a separate bowl, whisk together the granulated sugar, cocoa powder, and powdered sugar until smooth. Add the heavy cream and vanilla extract, and stir until everything is well combined.
3. Melt the Chocolate:
In a small microwave-safe bowl, microwave the chocolate chips for 20-30 seconds at a time, stirring in between, until melted and smooth. Once melted, fold the melted chocolate into the sugar and cream mixture, mixing until everything is fully combined into a smooth, fudgy batter.
4. Spread the Chocolate Mixture:
Pour the chocolate mixture over the graham cracker crust in the prepared pan. Use a spatula or the back of a spoon to spread it evenly across the base.
5. Add the Marshmallows:
Sprinkle the mini marshmallows over the top of the chocolate layer. Gently press them down into the fudge so they stick.
6. Chill and Set:
Place the dish in the refrigerator for at least 3 hours, or until the slice has set and become firm. For best results, let it chill overnight.
7. Cut and Serve:
Once set, remove from the fridge and slice it into squares. Serve chilled or at room temperature, and enjoy!
