Can you just add peanut butter to brownies?
Yes, you can absolutely can! Here are a few easy ways to do it, with this recipe covering them all!
- Swirl It In: Drop spoonfuls of creamy peanut butter on top of your brownie batter before baking. Use a knife to swirl it in for pretty peanut butter ribbons throughout.
- Mix It In: Stir a generous scoop (about 1/2 cup) of peanut butter directly into your brownie batter for a richer, nuttier flavor.
- Add Peanut Butter Chips: Fold in peanut butter chips to get melty pockets of peanut butter in every bite.
- Top with Frosting: Make a quick peanut butter frosting or glaze to spread on top once the brownies are baked and cooled.

Be sure to check your brownies around the 25-minute mark of baking. Brownies should have slightly crisp edges but still be fudgy in the middle. A toothpick with a few moist crumbs is perfect.
After baking, you’ll whip up an easy stovetop peanut butter frosting and finish it off with a sprinkle of chocolate chips for a picture-perfect treat.
Melted chocolate makes brownies rich, fudgy, and dense, while cocoa powder gives them a deeper chocolate flavor and a chewier texture. For the best of both worlds, some recipes use both—but it all depends on the texture you prefer!
Yes, you can! Use 3 tablespoons of peanut butter per egg. It works best in fudgy recipes and adds a rich, nutty flavor, though the texture may be slightly denser. Just make sure to use creamy peanut butter for the smoothest results.
Yes, just use the same amount—1:1 ratio—but expect a slightly denser texture and a delicious nutty flavor. For best results, use creamy peanut butter and warm it slightly so it mixes in smoothly. It’s a great way to add richness and cut back on processed oils.
Peanut butter adds moisture, richness, and a distinct nutty flavor to baked goods. It can make treats denser and chewier, especially in cookies and brownies. Since it contains fat, it can partially replace butter or oil, and its natural thickness can also help bind ingredients—making it useful as an egg substitute in some recipes. Just be sure to use creamy peanut butter for a smooth texture unless a chunkier bite is what you’re going for!
Absolutely! Just swirl in melted peanut butter before baking, or stir in peanut butter chips to instantly upgrade your mix.
How to Reheat Brownies
- For a quick option, microwave individual brownies for 10–15 seconds.
- To warm a batch, cover with foil and bake at 300°F for 8–10 minutes.
- You can also use an air fryer at 300°F for 2–3 minutes.
- Reheat gently if frosted to avoid melting the topping.

What chocolate chips??? Not in the recipe, but yet mentioned at the end of the instructions to top frosting with remaining chocolate chips…as if we had already used some somewhere else in the recipe!!! Please clarify! TY
Sorry for the confusion and thank you for pointing out my editing mistakes. I have updated the recipe. You only use about 1/2cup of chocolate chips to scatter on top of the peanut butter frosting.
Have you ever doubled this recipe for a 9×13?
I have not. But, I think it will be fine. Just keep a close eye on it and test frequently to see when it is finished because I have no idea on what the baking time will be.
