Chocolate Peanut Butter Cookie Bars

Chocolate Peanut Butter Cookie Bars
Not for the faint of heart. These are truly peanut butter-licious!

This is a crazy week here at our home. Spring sports are now in session. Add to that several commitments I made with catering and you have a full schedule. What makes a crazy night better?

Yep, chocolate and peanut butter. And now, with these bars, I don’t have to dip candy bars in my peanut butter jar. Not that I do that often.
Yield: 24 bars

Chocolate Peanut Butter Cookie Bars


  • 1 cup butter, softened
  • 3/4 cup brown sugar
  • 1 cup sugar
  • 2 eggs
  • 2 Tbsp milk
  • 2 tsp vanilla extract
  • 2 cup flour
  • 1/2 cup dark chocolate cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 15 oz peanut butter morsels, divided
  • 1 cup Reese's pieces candies


  1. Beat butter and sugars for 3 minutes. Add eggs, milk and vanilla. Add in flour, cocoa, baking soda and salt. Mix completely. Fold in 10 oz peanut butter chips and Reese's pieces candy.
  2. Spread dough (with fingertips) into a large cookie sheet. Bake in a 375 degree oven for 18-20 minutes. Remove and cool. Cut into 24 bars.
  3. Melt remaining peanut butter chips according to package directions (I used the microwave at 30 second intervals). Put melted chips into a ziploc sandwich bag, snip off the corner and drizzle over cooled cookie bars.
  4. Allow to set, about 15 minutes. Enjoy!
