485g Betty Crocker milk chocolate chunk cookie mixture
1/3 cup crushed nuts
80g Coles butter, softened
1 Coles Brand free range egg, lightly beaten
180g white chocolate, chopped
200g milk chocolate, chopped
Step 1 Preheat oven to 180C or 160C fan. Line a 28cm x 18cm slice tin with on-stick baking paper, extending over the two long sides.
Step 2 Empty contents of cookie mixture packet into a bowl and add nuts. Add butter and egg. Mix with a wooden spoon, and then your hands, to combine evenly. Press into tin, using the back of a spoon to smooth the surface. Bake for 20 mins or until golden brown. Cool in the tin.
Step 3 Place chocolate in separate bowls and microwave, one at a time, for 2 mins, or until soft. Stir until smooth. Drop spoonfuls of chocolates onto the slice, and use a skewer to create a marbled effect. Place in the fridge for 20 mins, or until set.
Step 4 Stand slice at room temperature for chocolate to soften slightly. Lift from the tin and cut into squares to serve.
