1/2 cup all-purpose flour – Helps provide structure; be careful not to overmix this to avoid tough brownies.

How to Make Peanut Butter Swirl Brownies
Follow these simple steps to prepare this delicious Peanut Butter Swirl Brownies:
Step 1: Melt the Butter
In a large mixing bowl, melt the unsalted butter. You can do this in the microwave or on the stove until it’s just bubbly, but be careful not to burn it!
Step 2: Mix in the Sugars
Add the granulated sugar and brown sugar to the melted butter, whisking until well combined. You want a smooth, shiny mixture—almost like a chocolate river flowing in your bowl.
Step 3: Add the Eggs and Vanilla
Crack in the eggs and pour in the vanilla extract. Whisk until the mixture is smooth and glossy, resembling a velvety chocolate sauce.
Step 4: Add the Dry Ingredients
Sift the cocoa powder, flour, and salt into the buttery goodness. Stir gently with a spatula, just until no dry streaks remain. Remember, overmixing is the enemy of brownie perfection!
Step 5: Prep the Baking Dish
Pour the luscious brownie batter into a greased or parchment-lined 8×8-inch baking pan. Level it out carefully; we’re aiming for an even bake.
Step 6: Create the Peanut Butter Swirl
In small dollops, drop the creamy peanut butter across the top of the brownie batter. Use a skewer or knife to gently swirl it through the batter—think of it as a modern art masterpiece.
Step 7: Bake and Cool
Bake in a preheated oven at 350°F (175°C) for 30–35 minutes. You’ll know they are done when a toothpick inserted in the center comes out with moist crumbs. Allow them to cool completely in the pan before slicing into intergalactic squares of heaven.
These Peanut Butter Swirl Brownies are perfect for all occasions, from cozy evenings on the couch to lively gatherings with friends. Serve them with a scoop of vanilla ice cream or a drizzle of chocolate sauce for an added touch of indulgence. Enjoy every decadent bite!
