¾cuppacked dark brown sugar (pack tightly or weigh)(170 grams)
1teaspoonvanilla extract
2largelarge eggs
6ouncesdark chocolate, cut into chunks
3ounceswhite chocolate, cut into chunks
⅔cuplightly salted roasted peanuts
Instructions
In a bowl, mix together the flour, baking soda, baking powder and salt and set aside.
In a mixing bowl, using an electric mixer, beat together the butter, peanut butter and both sugars until creamy. Beat in the vanilla and the eggs.
Add flour mixture and stir to make a soft dough. Stir in the dark and white chunks, then stir in the peanuts.
Divide dough into 20 balls and arrange on a parchment or foil lined plate. Chill for an hour, then bake in a preheated 350 degree oven for 12 to 15 minutes or until cookies appear set. Let cool on the baking sheet for 10 minutes, then carefully remove and let cool completely
Notes
I chilled my dough rounds for an hour because I think the cookies bake up a little thicker this way, but if you're in a hurry you could probably skip the chilling.
