Peanut Butter Chocolate Chip Cookie Bars

Soft and Chewy Peanut Butter Chocolate Chip Cookie Bars are loaded with rich chocolate and creamy peanut butter! With only 30 minutes to bake, you'll want to make this indulgent cookie bar recipe right away!

We had a busy, busy weekend full of Halloween parties and I made these delicious peanut butter chocolate chip bars to take to one Saturday evening. 

These bars are fantastic, just like our turtle cookie bars or cranberry crumb bars, they are always the first sweet to be devoured at parties. You just can't go wrong with pairing PB and chocolate, am I right?

Ingredients

This is an easy recipe made with pantry staples.

• flour
• salt
• baking soda
• brown sugar
• peanut butter
• butter or margarine
• sugar
• egg
• vanilla extract
• chocolate chips
• peanut butter chips

Step by step

1. Whisk together flour, salt, and baking soda in a bowl and set aside. In a stand mixer (affiliate link) mix brown sugar, peanut butter, butter, and sugar until smooth.
2. Add in egg and vanilla extract and mix on medium speed until just combined. Reduce mixer speed to low and add in flour mixture.
3. Remove from mixer and mix in chocolate and peanut butter chips by hand. Spread the batter in the pan and bake 25 to 30 minutes until golden and center is done.
4. Cool on a rack and slice into 16 bars once cool.

Tips for best results

• You can use either crunchy or smooth peanut butter but do not use natural versions, the end result won't be the right texture due to the separation of oil.
• Choose any kind of chocolate chip you want, dark chocolate, semisweet, milk chocolate: it's up to you, they will all turn out delicious!
• For thicker bars use a 9 by 9-inch pan and extend the baking time by about five minutes.
