Makes 54
2 cups flour
3/4 cup unsweetened cocoa powder
1 tsp baking soda
1/2 tsp salt
1 1/4 cups butter, softened
2 cups sugar
2 eggs
2 tsp vanilla
1 2/3 cup Reese’s peanut butter chips

Pre-heat oven to 180C/160C fan-forced/350F. Line two large baking trays with non-stick baking paper.

In a large bowl beat butter and sugar together until light and fluffy, add vanilla and eggs and beat to combine. In a separate bowl combine flour, cocoa, baking soda and salt, then beat into the butter mixture until just combined. Add the peanut butter chips and mix through with a spoon.

Drop teaspoonfuls onto the trays about 2 inches apart and bake for 12 minutes, swapping trays halfway through. They are quite soft and sticky when they come out of the oven and need to cool on the tray for 6 minutes before transferring to a wire rack to finish cooling.
