If you're looking for a rich and delicious treat to feed a crowd, look no further. These peanut butter cookie bars are easy to make and pack a punch of peanut butter flavor. We start out with an oatmeal peanut butter cookie base, then spread peanut butter over it evenly, then add a layer of melted chocolate chips. Finally, a handful or two of chopped peanuts is sprinkled over the bars before cutting into squares!

Chocolate Peanut Butter Cookie Bars

Ingredients

• 1 cup butter
• 1 cup packed brown sugar
• ¾ cup white sugar
• 1 cup peanut butter
• 2 eggs
• 1 ½ cups all-purpose flour
• 2 teaspoons baking soda
• 1 teaspoon salt
• 1 cup quick-cooking oats
• 1 ½ cups peanut butter
• 3 cups chocolate chips
• ½ cup chopped peanuts (optional)

Directions

1. Mix the dough ingredients together and spread into a half sheet pan. Bake 20-25 minutes.
2. Next, we'll add a layer of peanut butter over the warm cookie bars.
3. IMPORTANT: let the cookie bars stand 10 minutes before spreading peanut butter over them. Add peanut butter by small spoonfuls across cookie bars and let stand for a few minutes to allow the peanut butter to soften and begin to melt. THEN spread over bars. 
4. Melt chocolate chips and pour over bars. Spread the chocolate evenly.
5. Sprinkle with chopped nuts.

These are delicious served warm and gooey, and just as good after the chocolate has had a chance to cool and set up. Chocolate peanut butter cookie bars can be stored, covered, at room temperature up 5 days.
