These Peanut Butter Cookie Bars are soft in the center, golden at the edges, and packed with chocolate chips in every bite. They're the one-pan treat you'll come back to again and again—easy to make, full of nostalgic flavor, and perfect for connecting around the table.
Turn down the mixer to low speed and slowly add the flour, a couple of tablespoons at a time, until just combined.
1 cup all purpose flour
Reserve 2 tablespoons of the chocolate chips and add the remaining chocolate chips to the batter and use a rubber spatula to fold them through.
3/4 cup chocolate chips
Spoon the batter into the prepared pan and spread out evenly.
Sprinkle the chopped peanuts (if using) and reserved chocolate chips over the top of the bars.
2 tablespoons chopped peanuts
Bake for 25 minutes. Cool the bars completely in the pan before slicing and serving.
Notes
Peanut Butter Cookie Bars are the easy cousin of your classic cookie — baked in one simple pan and sliced into golden perfections. The texture is a cross between a soft baked cookie and a fudgy blondie that absolutely melts in your mouth. They’re very peanut-y, but the sweetness of brown sugar and vanilla balances it out. A scattering of chocolate chips throughout the batter adds little pools of melty richness in every bite. These bars are pure comfort, soft in the middle and slightly crispy on the outside and full of nostalgic flavor.
Store leftovers in an airtight container or covered in plastic wrap for up to 3 days.
You can freeze these bars in an airtight container for up to 3 months. Thaw at room temperature when you are ready to serve.
Use the commercial creamy peanut butter like Skippy or Jif. Natural peanut butters don't give the same texture.
I used smooth peanut butter for this recipe but crunchy peanut butter works too.
It’s tempting to dive into the pan straight from the oven but it really needs time to cool so that the cookie can set and won’t be crumbly when you slice them.
If you find peanut butter cookies a little too sweet, sprinkle a little bit of sea salt over the top before baking. Have a little fun with it.
I used chocolate chips but peanut butter or butterscotch chips or even a swirl of jam or nutella can be fun to add and will give you a different flavours and textures.
