Ingredients for Peanut Butter Swirl Brownies

1/4 cup brown sugar – Offers a hint of caramel-like depth to your brownies.
2 large eggs – Essential for binding the ingredients and adding moisture.
1 teaspoon vanilla extract – A must-have for enhancing the sweet and nutty flavor profile.
1/2 cup all-purpose flour – Provides the structure necessary for your brownies to hold together beautifully.
1/3 cup unsweetened cocoa powder – Gives that deep chocolate flavor we all crave.
1/4 teaspoon salt – Just a touch balances the sweetness and enriches the overall flavor.
1/3 cup creamy peanut butter – The star of the show that brings ooey-gooey goodness to each bite.
How to Make Peanut Butter Swirl Brownies
Follow these simple steps to prepare this delicious Peanut Butter Swirl Brownies:
Step 1: Melt the Butter
Start by melting the unsalted butter in a large mixing bowl. You can do this in a microwave or on the stovetop—whichever you prefer! Once melted, let it cool slightly before proceeding.
Step 2: Mix in Sugars
Add the granulated sugar and brown sugar to the melted butter. Whisk everything together until well blended; it should be smooth and shiny.
Step 3: Incorporate the Eggs and Vanilla
Crack in the two large eggs and pour in the vanilla extract. Whisk vigorously until the mixture is fully combined and you can no longer see any of the egg yolk.
Step 4: Add Dry Ingredients
Sift in the cocoa powder, flour, and salt. Gently stir with a spatula until just combined—be careful not to overmix. A few flour streaks are perfectly fine!
Step 5: Prepare for Baking
Pour the brownie batter into a greased or parchment-lined 8×8-inch baking pan. With a spatula, spread it evenly across the pan.
Step 6: Swirl That Peanut Butter
Dollop the creamy peanut butter on top of the brownie batter in spoonfuls. Then, using a skewer or a knife, gently swirl the peanut butter into the chocolate goodness to create a marbled effect—feel free to go wild; the more swirls, the better!
Step 7: Bake to Perfection
Preheat your oven to 350°F (175°C) and bake for about 30–35 minutes. A toothpick inserted should come out with moist crumbs, which means they are just the right level of fudgy.
Step 8: Cool and Serve
Allow the brownies to cool completely in the pan before slicing them into squares. Enjoy them as is, or with a scoop of vanilla ice cream for an indulgent treat!
Now that you’ve crafted a batch of these Peanut Butter Swirl Brownies, be prepared to share (or not!) as everyone will be asking for a taste. Maybe you’ll even relive some of those childhood memories just like I did. Happy baking!
