Double-Decker Bars

Double-Decker Bars

Every now and then, I go too far. When that happens, I’m woman enough to admit it. And I have no shame at all.

These bars go waaaaaay too far. And like I said, not sorry. Just be prepared, because you may have to go where other people are not in preparation for the sugar crash that will inevitably come your way if you eat these. It will be worth it. I speak the truth.

Double-Decker Bars

These double-decker beauties have two awesome layers. The bottom is a chewy peanut butter bar filled with Reese’s Oreos. Honestly, they’d be good by themselves. Nobody would complain at all.

But I went farther! I took leftover cookie dough from my One-Bowl Chocolate Chunk Cookies and layered it on top. See, I rarely bake a full batch of cookies. It’s just too much, and I like to have fun with cookie dough. If you don’t have a half-batch handy, you can use 16 oz. of refrigerated chocolate chip cookie dough. It’ll do the job and then some!

You bake the peanut butter bar layer first to near-doneness. Then you spread the cookie dough flat with your fingers and place it on top and bake even more. The result is chewy amazingness. Who doesn’t want a giant chocolate chunk cookie layer on top of their Reese’s PB Oreo bars?

But you know, you just have to be wise. Eat a few at a time. The whole pan could be dangerous. Or wonderful. Let me know!

These bars are thick and irresistible. If you’re in the mood to go too far, this is the dessert for you! Hey, better to go crazy in the kitchen than succumb to road rage. It’s all relative!



  • 1/2 cup butter, melted
  • 1/3 cup peanut butter
  • 1 egg
  • 1 cup light brown sugar, firmly packed
  • 1 tablespoon vanilla
  • 1 cup flour
  • 8 Oreos, broken into quarters
  • 1/2 batch chocolate chip cookies or 16 oz. refrigerated cookie dough



Preheat the oven to 350. Coat an 8 x 8 pan with cooking spray.

Combine the butter and peanut butter in a medium-sized bowl and stir until well mixed. Add the egg and stir again. Mix in the brown sugar and vanilla, being sure all ingredients are incorporated. Gradually add the flour, stirring until just combined. Fold in the Oreo pieces.

Bake for 25 minutes until set.

Using your fingers, spread the cookie dough flat with your fingers and layer it over the peanut butter bars, covering them completely. Bake for another 20-25 minutes until firm.

Cool completely and cut into bars.




I fulfill many roles in life: wife, mother, teacher, everlasting learner. This site is dedicated to one role that expresses my creativity in ways that I find consistently challenging and rewarding: baker. Inventing new ways to enhance food, especially if that food involves chocolate or peanut butter (or both!), is a passion of mine. I look forward to sharing my ideas with you.
