If you’re all about layered desserts that go big on flavor, these Peanut Butter Cookie Dough Brownies are your dream come true. You get rich, fudgy brownies baked with peanut butter cups, then topped with a thick, creamy layer of Peanut Butter Cookie Dough—yes, the kind you can eat by the spoonful. It’s the kind of over-the-top treat that turns any casual hangout into a full-blown dessert moment.
Do I have to heat-treat the flour?
Yes—if you’re making edible cookie dough, the flour must be heat-treated to kill any bacteria. Microwave in 30-second intervals until it reaches 165°F, or bake at 350°F for 5–7 minutes.
Can I use natural peanut butter?
It’s not recommended. Natural peanut butter can separate and make the dough oily or gritty. Stick to a no-stir, creamy peanut butter for best results.
Should the brownies be fully cooled before adding the cookie dough?
Let them cool slightly but not completely—spreading the cookie dough over warm brownies helps it adhere better and makes for a gooier texture once chilled.

Can I make Peanut Butter Cookie Dough Brownies ahead of time?
Yes! They’re great made a day in advance. Just store them in the fridge and bring to room temp before serving.
How do I store leftovers?
Keep them covered in the fridge for up to 5 days. You can also freeze individual bars.
Can I use a different size pan?
An 8” pan makes thick layers, but a 9” pan works too—just reduce the bake time slightly and keep an eye on doneness.
Are these safe to eat raw?
The cookie dough layer is egg-free and made with heat-treated flour, so yes—it’s safe to eat.
What kind of brownie mix is best for this recipe?
A fudgy brownie mix (like Ghirardelli or Betty Crocker Fudge) works best since it balances the thick cookie dough topping.
This is the dessert to make when the weather calls for blankets and binge-watching. Pick a rainy day, cozy up on the couch with a cup of hot tea, and let a pan of Peanut Butter Cookie Dough Brownies be your comfort snack of choice. The sound of rain tapping the windows, a new series queued up, and a forkful of brownie + cookie dough is a whole mood.
Buttery, sweet sugar cookie cups filled with vanilla buttercream and rainbow sprinkles!
