Method

step 1

Line a 20 x 20cm square tin with baking parchment and heat the oven to 180C/160C fan/gas 4. Melt 125g butter in a saucepan over a low heat, then leave to cool for 10 mins.
step 2

Stir the sugars, egg and vanilla into the melted butter. Weigh the flour and baking powder in a bowl, add ½ tsp salt. Tip into the butter mixture and stir well to make a soft dough. Stir through the M&M'S® Minis and 25g of the chopped dark chocolate.
step 3

Tip the dough into the tin and use a spatula to press it to the edges and into the corners. Bake for 20 mins until golden brown, then cool completely in the tin – it will sink slightly as it cools.
step 4

Melt the remaining 75g dark chocolate, 25g butter and the cream in a pan over a low heat, stirring regularly to prevent it from burning. Once smooth and combined, remove from the heat and cool for 5 mins. Pour the ganache over the cookie and decorate with the Chocolate M&M’S®. Leave to set, then cut into 18 bars. Will keep in an airtight container for up to four days.
