Preheat the Oven: Preheat your oven to 180°C / 350-375°F / Gas Mark 4-5.
Cream butter and sugar: Use electric beaters to cream butter till pale and creamy, add vanilla extract and combine.
Add flour and cocoa powder: sift the flour and cocoa powder into the butter mixture and combine. Use a spatula at the end so the cook dough forms a ball.
Portion into cookies: use a mini cookie scoop to portion the mixture across the 2 baking trays. Give the cookies a little bit of space as they will spread.
Prepare the Snickers: use a knife and chopped board to cut the snickers into pieces, set aside.
Oven Bake: place the baking trays into the oven and cook the biscuits for 12 to 15 minutes. Remove when cooked, but leave on the baking tray to cool.
Once Cool: use a flat silicon utensil and slide it under each cookie, transferring them to a wire rack.
Decorate: heat the caramilk chocolate in the microwave for 2 mins, stir, then spoon a teaspoon of it over the top of each cookie. Place the Snickers pieces on top of the melted chocolate and let set.
Store: once the biscuits have fully cooled and the chocolate has set, place them in an air tight container.
