- 1 cup unsalted butter
- ½ cup semi-sweet chocolate morsels
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- ¾ cup unsweetened cocoa powder
- 1 cup all-purpose flour
- ½ teaspoon kosher salt
- ½ teaspoon baking powder
- ½ cup creamy peanut butter
Variations
One of the best things about this Peanut Butter Brownies recipe is how flexible it is. Here are some fun ways to switch things up:
- Add nuts: Toss in some chopped walnuts or pecans for extra crunch.
- Go dark: Use dark chocolate morsels instead of semi-sweet for a richer flavor.

How to Make Peanut Butter Brownies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line a 9-inch baking dish with parchment paper. This step ensures that your brownies bake evenly and don’t stick to the pan.
Step 2: Melt the Butter
In a medium-sized saucepan over medium heat, melt the butter until it’s completely liquid. Once melted, remove it from heat and stir in the semi-sweet chocolate morsels along with granulated sugar. This creates a smooth, glossy base full of rich flavor.
Step 3: Add Eggs and Vanilla
Next, add in the eggs one at a time, stirring well after each addition. Stirring thoroughly helps incorporate air into the batter which contributes to that delicious fudgy texture we all love! Don’t forget to mix in the vanilla extract—it adds such warmth to our brownies.
Step 4: Combine Dry Ingredients
Now it’s time to add all those dry ingredients: cocoa powder, flour, salt, and baking powder. Gently fold everything together using big strokes until just combined. Be careful not to over-stir—it’s okay if there are still small pockets of dry ingredients because this keeps our brownies nice and dense.
Step 5: Swirl in Peanut Butter
Pour the brownie batter into your prepared dish and dollop creamy peanut butter on top. Take a knife and swirl it through the batter gently; this creates beautiful marbled patterns that look as good as they taste!
Step 6: Bake and Cool
Bake your Peanut Butter Brownies for about 40-45 minutes until they are set but still moist in the center. Once baked, allow them to cool completely before cutting into squares—this patience is worth it when you get that perfect clean slice!
Enjoy every bite of these delicious homemade treats!
Pro Tips for Making Peanut Butter Brownies
Making the perfect Peanut Butter Brownies is easier than you think! Here are some handy tips to elevate your baking game:
- Use room temperature ingredients: Bringing your eggs and butter to room temperature helps create a smoother batter, ensuring even mixing and optimal texture.
- Don’t overmix: Stirring just until combined prevents tough brownies. You want that fudgy texture, so be gentle with your mixing!
- Check for doneness carefully: Ovens can vary, so start checking your brownies a few minutes before the recommended time. A toothpick should come out with a few moist crumbs for that perfect fudgy center.
- Let them cool completely: Allowing the brownies to cool in the pan lets them set properly, making it easier to cut clean squares without crumbling.
- Experiment with mix-ins: Feel free to add chocolate chips, nuts, or even a sprinkle of sea salt on top before baking for an extra flavor boost!
