- Prepare the Cookie Mixture
- In a large mixing bowl, break the cookies into small chunks. Aim for bite-sized pieces rather than crumbs to retain a nice texture in the final cake. Add the chopped walnuts and stir to distribute evenly.
- Make the Chocolate Mixture
- In a saucepan, combine the cocoa powder, sugar, and milk. Heat over low to medium heat, stirring continuously until the mixture is smooth and the sugar has dissolved. Avoid boiling; just heat enough to blend everything well.
- Add the Butter and Melted Chocolate
- Remove the saucepan from the heat and stir in the melted butter and melted chocolate. Mix until everything is well combined, resulting in a glossy, thick chocolate sauce.
- Combine the Mixtures
- Pour the chocolate mixture over the cookie and walnut mixture. Use a spatula to gently fold everything together until the cookies and nuts are fully coated in chocolate.
- Shape the Cake
- Line a small loaf pan or round cake pan with parchment paper. Transfer the mixture into the prepared pan, pressing it down firmly to remove any air pockets and create an even layer. Smooth the top with the back of a spoon or spatula.
- Chill and Set
- Place the cake in the refrigerator and chill for at least 2 hours, or until it’s firm and set. For a firmer texture, you can leave it to chill overnight.
- Serve
- Once set, remove the cake from the pan and cut into slices. Serve chilled or at room temperature, depending on your preference.
