Step-by-Step Instructions

Follow each step to make the recipe successfully.

  1. Prepare the Biscuit Base

    Crush 250g of plain chocolate cookies until they are nice and fine. You can use a food processor or place them in a bag and hit them with something heavy. Add 90g of melted butter to the crushed cookies and mix until well combined.

  2. Press the Base into a Pan

    Lightly grease and line a standard slice pan (approximately 30cm x 20cm) with non-stick baking paper. Pour the biscuit mixture into the pan and use a flat-bottomed glass to press it down firmly and evenly across the entire surface. Place the pan in the fridge to chill while you prepare the filling.

  3. Prepare the Peanut Butter Filling

    In a saucepan over medium heat, melt 90g of butter until it is nice, bubbly, and foamy. Add 1/2 cup of brown sugar, 1 1/2 cups of icing sugar (also known as powdered or confectioner's sugar), and 1 cup of thick, smooth peanut butter to the melted butter.

  4. Mix the Filling

    Using a wooden spoon, mix all the ingredients in the saucepan together until they are melted and smooth. Turn off the heat once combined.

  5. Add Chocolate Chips to the Filling

    Add 1/2 cup of dark chocolate chips to the peanut butter mixture and stir them through until evenly distributed.

  6. Spread the Filling

    Retrieve the chilled cookie base from the fridge. Spread the peanut butter mixture evenly over the surface of the cookie crumbs. Return the pan to the fridge for , or until the peanut butter mixture has set.

  7. Prepare the Chocolate Topping

    Place 150g of good quality dark chocolate (broken into pieces) into a microwave-safe bowl. Microwave for about , then stir with a metal spoon. Continue microwaving in 20-second intervals, stirring after each, until the chocolate is completely melted and smooth.

  8. Apply the Chocolate Topping

    Pour the melted chocolate over the set peanut butter layer. Use a spoon or spatula to smooth it out evenly across the entire surface. Pop the pan back into the fridge for about to allow the chocolate topping to set.

  9. Slice and Serve

    Once the chocolate topping is set, lift the entire slice out of the pan using the baking paper. Carefully peel back the paper. Using a sharp knife, cut the large slice into smaller 2cm (1 inch) squares. Serve and enjoy!
