How to Make Peanut Butter Cookie Bars
Peanut Butter Cookie Bars
Ingredients
- 1 cup granulated sugar
- 1 1/4 cups brown sugar
- 3/4 cup unsalted butter melted
- 3/4 cup natural creamy peanut butter
- 3 eggs
- 2 teaspoons vanilla extract
- 2 1/2 cups flour
- 2 teaspoons baking powder
- 1 teaspoon salt
- 1 1/2 cups chocolate chips see notes
Instructions
- Preheat your oven to 325*F and line a baking pan with parchment (or foil). Leave some paper hanging over the sides, so you can easily pull the bars out of the pan after baking. Lightly butter any portion of the pan that is not covered in paper (this should be the two shorter sides of the pan)
- In a large mixer, blend together both sugars and warm, melted butter. Blend until well combined, then add peanut butter, eggs (one at a time) and vanilla and continue to blend until fully combined.
- In a separate bowl whisk together flour, baking powder and salt. Then, while the mixer is on low, slowly add the flour to the butter/sugar mixture. Stop the mixer immediately when you have added all the flour.
- Add chocolate chips (or chips of your choice) and blend until just combined.
- Scoop dough into prepared pan and spread with an off-set spatula (the surface should be level before baking).
- Bake 35-40 minutes, or until the top is golden brown and there is no wet batter visible.
- Remove from oven and allow to cool FULLY before cutter (1 hour or more). For easiest cutting, run a knife around any edges of the bars that are touching the sides of the pan, then pull up on the parchment paper and place the giant bar on a cutter board. Cut with a serrated knife, wiping off between cuts as needed.

This recipe…why are they so thick lol? They’ve been baking for an hour and Still not cooked >:(
The bars should be nice and thick. I baked mine in a good quality metal pan. If you are using a glass pan it may take a bit longer. The bars will continue to bake after you remove them from the oven, so be sure to pull them from the oven with the center is still a bit underdone, and then allow the full cooling time.
What size pan do you recommend?
They look easy to make- that’s always good!
