Ingredients

Scale

For the Base:

  • 2 cups (200g) crushed chocolate biscuits (Oreos or graham crackers)
  • 1/2 cup (115g) unsalted butter, melted
  • 2 tbsp cocoa powder

For the Mint Filling:

  • 2 cups (250g) powdered sugar
  • 1/4 cup (60g) unsalted butter, softened
  • 2 tbsp milk
  • 1 tsp peppermint extract
  • A few drops of green food coloring (optional)

For the Chocolate Topping:

  • 1 1/2 cups (270g) dark or milk chocolate chips
  • 2 tbsp butter or coconut oil (for a glossy finish)

Instructions

1. Make the Chocolate Base

  1. Grease and line an 8×8-inch (20cm) baking pan with parchment paper.
  2. In a bowl, mix crushed biscuits, melted butter, and cocoa powder until combined.
  3. Press the mixture firmly into the pan and chill in the fridge while preparing the filling.

2. Prepare the Mint Layer

  1. In a bowl, beat powdered sugar, softened butter, milk, and peppermint extract until smooth.
  2. Add green food coloring if using and mix until evenly colored.
  3. Spread the mint layer over the chilled chocolate base and smooth the top.
  4. Place back in the fridge for 30 minutes to set.

3. Make the Chocolate Topping

  1. Melt chocolate chips and butter (or coconut oil) in the microwave in 30-second intervals, stirring until smooth.
  2. Pour the melted chocolate over the mint layer and spread evenly.
  3. Chill in the fridge for 1 hour, or until completely set.

4. Slice & Serve

  1. Once firm, remove from the pan and cut into squares or slices.
  2. Serve chilled and enjoy!

Notes

  • Make it extra minty: Add crushed peppermint candy on top before the chocolate sets.
  • For a crunchier texture: Add 1/4 cup chopped nuts to the base.
  • Storage: Keep in an airtight container in the fridge for up to 5 days or freeze for up to 2 months.
