Preheat oven to 350 degrees F. Line a baking sheet with parchment paper.
Mix together crust ingredients. Form into 12 cookies (~ 1 tbsp each) and press a thumbprint into the center of each cookie.
Bake for 10-12 minutes.
Let cookies cool, then add ~1 tsp peanut butter mixture to the center of each cookie. Freeze for 10-15 minutes.
Dip each cookie in melted chocolate. Freeze again for ~10 minutes, or until chocolate hardens.
Enjoy!
