Chocolate Chip Peanut Butter Cookie Bars

My favorite recipes to make are those that I can easily make with my daughter, and this is one of them! These Peanut Butter Chocolate Chip Cookie Bars (also known as Peanut Butter Blondies) are delicious and super easy to make. 

This is an easy recipe where you can let your child do all of the mixing and prep while you watch and assist. And if you don’t have a young child, you’ll be happy with how easy it is for you to make as well! 

You’ll notice that I don’t specify what chocolate chips to use in these delicious bars, and that’s because I want you to choose your favorite! If you like dark chocolate, milk chocolate or even broken up peanut butter cups, they will work. When matched with the peanut butter flavor, it’s like your favorite chocolate chip cookies in bar form and on a whole other level. 

This Peanut Butter Cookie Bars recipe has fairly standard ingredients, but if you are looking for a gluten free option, you will need to change up the dry ingredients. You can use almond flour or coconut flour in this recipe, but you should do some research as to how to alter the baking powder or the amount of alternative flour you will be using. It is not quite 1:1.  

Peanut Butter Chocolate Chip Cookie Bars Recipe

How To Make:

Ingredients:
3/4 cup butter (softened to room temperature)
3/4 cup granulated sugar
3/4 cup packed brown sugar
1/2 cup creamy peanut butter
2 eggs
1 1/2 tsp vanilla extract
2 1/2 cups all purpose flour
1 Tbsp baking powder
1/2 cup overflowing chocolate chips (the overflow will be to sprinkle on top)
1/2 cup overflowing peanut butter chips (the overflow will be to sprinkle on top)

Preheat your oven to 350 degrees and line a 9×13 inch pan with foil or parchment paper. If you’re using foil, spray it with a non-stick cooking spray; for parchment paper you won’t need to.

Using a stand mixer or large bowl, mix the softened butter, sugar, brown sugar, eggs, peanut butter and vanilla.

Next, slowly add the flour and baking powder into your mixture. Make sure that everything has been incorporated, using a rubber spatula to scrape the sides of the bowl.

Lastly, add in most of the chocolate chips and peanut butter chocolate chips until they’re just incorporated. Don’t overmix them.

Evenly spread the cookie dough into your baking dish. Sprinkle the top of the dough with the extra baking chips of each flavor. Bake for 20-25 minutes until golden brown (check with a toothpick to make sure it’s cooked through). You want this batch of cookies to have crispy edges of the pan and chewy cookie bars in the middle.

Remove your pan from the oven and allow the bars to cool completely in the baking dish. If you’d prefer to cool your peanut butter bars on a wire rack or cookie sheet, you can.

Once cooled, lift the foil/parchment paper up and out of the pan and cut your bars on a flat surface. Enjoy! 

Store on a plate under plastic wrap or in an airtight container. 

Can I Use Different Kinds Of Peanut Butter In These Peanut Butter Chocolate Chip Bars?

Yes! This easy recipe calls for creamy peanut butter, but you could easily replace it with crunchy peanut butter. I have not tried these specific peanut butter cookies with natural peanut butter, so please leave a comment if you do. I’d love to know how they turn out!
