I make these Chocolate Peanut Butter Brownies whenever I crave something deeply chocolatey with a creamy, nutty swirl. These brownies are rich, fudgy, and perfectly balanced with smooth peanut butter woven into every bite. The combination of chocolate and peanut butter creates a classic dessert that feels both indulgent and comforting.
Why You’ll Love This Recipe
I love how simple these brownies are to prepare while still delivering bakery-style results. The texture turns out perfectly fudgy in the center with just the right amount of chewiness around the edges. The peanut butter swirl adds a creamy contrast to the deep chocolate flavor, making each bite irresistible. I also appreciate that I can make them with basic pantry ingredients, and they come together in under an hour from start to finish. Whether I bake them for family gatherings or just to satisfy my sweet tooth, they always disappear quickly.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup creamy peanut butter
1/2 cup melted butter or coconut oil
3/4 cup granulated sugar
1/4 cup brown sugar
2 large eggs
1 teaspoon pure vanilla extract
1/2 cup all-purpose flour
1/3 cup unsweetened cocoa powder
1/4 teaspoon salt
1/2 teaspoon baking powder
1/3 cup chocolate chips (optional)
Directions
I start by preheating the oven to 350°F (175°C) and lining an 8×8-inch baking pan with parchment paper.
In a large mixing bowl, I whisk together the melted butter (or coconut oil), granulated sugar, and brown sugar until the mixture is smooth and well combined.
Next, I add the eggs and vanilla extract, beating everything together until the batter becomes glossy and fully incorporated.
I stir in the flour, cocoa powder, salt, and baking powder, mixing just until combined. I make sure not to overmix, as that helps keep the brownies tender and fudgy.
If I decide to use chocolate chips, I gently fold them into the batter at this stage.
I spread the brownie batter evenly into the prepared baking pan. Then I drop spoonfuls of peanut butter over the top and use a knife to gently swirl it into the batter, creating a marbled effect.
I bake the brownies for 25–30 minutes, until the center is set but still slightly fudgy. After baking, I allow them to cool completely before slicing into squares and serving.

Variations
I sometimes add chopped roasted peanuts for extra crunch and texture. When I want an even richer flavor, I mix dark chocolate chunks into the batter instead of regular chocolate chips. For a slightly salty contrast, I sprinkle a pinch of flaky sea salt on top before baking. If I prefer a dairy-free option, I use coconut oil instead of butter, which works beautifully in this recipe.
Storage/Reheating
I store the brownies in an airtight container at room temperature for up to 3 days. If I want them to last longer, I refrigerate them for up to a week.
To reheat, I warm a brownie square in the microwave for about 10–15 seconds to bring back that soft, fudgy texture. I also freeze them for up to 2 months, wrapping each square individually and thawing at room temperature when ready to enjoy.

FAQs
How do I know when the brownies are done?
I check the center with a toothpick. If it comes out with a few moist crumbs but not wet batter, I know they are perfectly fudgy and ready to come out of the oven.
Can I use natural peanut butter?
I can use natural peanut butter, but I make sure it is well stirred. The texture may be slightly different, but it still tastes delicious.
Can I double the recipe?
I double the ingredients and bake the batter in a 9×13-inch pan. I may need to adjust the baking time slightly and keep an eye on the center.
Why are my brownies dry?
If my brownies turn out dry, it is usually because I overbaked them. I remove them from the oven as soon as the center is just set to keep them moist.
Can I make these brownies gluten-free?
I substitute the all-purpose flour with a 1:1 gluten-free baking flour blend, and I still get a rich, fudgy result.
Conclusion
I find these Chocolate Peanut Butter Brownies to be the perfect dessert when I want something rich, comforting, and easy to prepare. The fudgy chocolate base combined with creamy peanut butter swirls creates a timeless flavor pairing that I never get tired of. Every time I bake them, they bring warmth and satisfaction to my kitchen, and I always look forward to that first delicious bite.
