Step 1

In a food processor, crush nutter butter cookies until fine crumbs form.

Step 2

Add the crumbs, sugar, and baking powder to a 6-8oz. microwave safe mug, and stir.

Step 3

Add the milk and mix to combine.

Step 4

Microwave for 1 minute, adding 10 seconds more if needed.

Step 5

Remove from the microwave and let cool for 2-3 minutes before serving.

Step 6

Dust with powdered sugar and top with a chopped Reeses’s cup.

Step 7

Microwave times may vary based on microwave strengths, so starting at 1 minute and adding 10 additional seconds at a time will help fully cook the mug cake.

Step 8

3 cookies equals 1.6 ounces of crumbs.
