These easy no-bake Christmas cookies combine cocoa, walnuts, and crushed biscuits in a soft, truffle-like mixture shaped into festive little trees. They’re quick to prepare and a fun holiday treat to make with kids.
Combine the ground biscuits, sugar, cocoa powder, walnuts, vanilla sugar, butter, and rum essence in a large bowl. Mix and knead until well combined.
Add the milk gradually, a little at a time, until the mixture comes together into a firm dough that holds its shape without being crumbly. You may not need all the milk.
Shape the mixture into small balls. Press each ball firmly into a Christmas tree mold. If you don’t have one, a small funnel can be used to create a simple cone-shaped tree.
Carefully remove the cookies from the mold and arrange them on a plate or tray. Refrigerate for about 30 minutes, or until firm.
Before serving, dust with powdered sugar for a snowy effect or sprinkle with coconut flakes.
