Preheat your oven to 350 degrees F and line two baking sheets with parchment paper or silicone mats.
To make crunch coat, combine granulated sugar, sprinkles, and chopped peanuts. Set that aside while you make the cookie dough.
In a large mixing bowl, combine softened butter, crunchy peanut butter, brown sugar, granulated sugar, an egg, and vanilla extract.
Once mixed, sprinkle in flour, baking soda and baking powder to form a dough.
Roll the dough into 2-inch sized balls, coat in egg white, then roll in the peanut and sprinkle mixture from earlier.
Bake for 10-12 minutes or until lightly golden on the edges. Let cool completely on the baking sheets before enjoying.
