How to Make Peppermint Slice
- In a large bowl, combine the graham cracker crumbs, cocoa powder, granulated sugar, and salt. Stir in the melted butter until the mixture resembles wet sand.
- Press the crumb mixture evenly into the bottom of a 9x9-inch square baking pan lined with parchment paper. Refrigerate for at least 30 minutes to set.
- While the base chills, prepare the mint layer by whisking together powdered sugar, heavy cream, and peppermint extract in a medium bowl until smooth and creamy.
- Spread the mint filling evenly over the chilled base and return the pan to the refrigerator for another 30 minutes to firm up.
- For the chocolate topping, melt the chocolate chips and butter together in a heatproof bowl over simmering water, stirring until smooth and glossy.
- Pour the melted chocolate over the mint layer and spread it evenly with a spatula. Sprinkle crushed candy canes on top while the chocolate is still warm.
- Return the slice to the refrigerator for at least 1 hour, or until the chocolate is fully set.
- Lift the peppermint slice out of the pan using the parchment paper edges and cut it into 16 squares with a sharp knife.
- Serve chilled for the best texture and flavor.
Tips for the Best Results
- Use fresh peppermint extract for a bright, authentic mint flavor.
- Make sure the base is firmly chilled before adding the mint layer to prevent mixing.
- When melting chocolate, avoid overheating to keep it smooth and glossy.
- Press the crumb base firmly to avoid crumbling when slicing.
- Store the peppermint slice in an airtight container to maintain freshness and texture.
Storage and Reheating
Store your peppermint slice in an airtight container in the refrigerator for up to one week. This keeps the layers firm and the flavors fresh. For longer storage, place the slice in the freezer wrapped tightly in plastic wrap and foil; it will keep well for up to 3 months.
To thaw frozen peppermint slice, transfer it to the refrigerator overnight before serving. Because this slice is best enjoyed chilled, reheating is not recommended.
Frequently Asked Questions
Can I use a different type of cookie base?
Yes, you can substitute graham cracker crumbs with crushed digestive biscuits or chocolate cookies for a different flavor. Just be sure to adjust the sweetness accordingly.
Is it possible to make this peppermint slice vegan?
To make a vegan version, substitute butter with coconut oil or a vegan butter alternative, use dairy-free chocolate chips, and replace heavy cream with a plant-based cream or coconut cream.
How do I prevent the chocolate topping from cracking?
Allow the chocolate to set at room temperature initially and then chill it gently in the fridge. Avoid rapid temperature changes which can cause cracking.
Can I add nuts or other toppings?
Absolutely! Chopped nuts, like almonds or pistachios, can be sprinkled on top with the candy canes for added crunch and flavor.
