Ingredients

For the Brownie Batter

• 1 cup unsalted butter (melted)
• 1 ½ cups granulated sugar
• 1 cup brown sugar
• 4 large eggs
• 1 tablespoon vanilla extract
• 1 cup all-purpose flour
• ¾ cup unsweetened cocoa powder
• ½ teaspoon salt
• ½ teaspoon baking powder

For the Peanut Butter Swirl

• ¾ cup creamy peanut butter
• 2 tablespoons powdered sugar (optional, for sweetness)

Step-by-Step Cooking Guide

Step 1 – Prepare the Oven

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.

Step 2 – Mix Wet Ingredients

In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs one at a time, then mix in vanilla extract.

Step 3 – Add Dry Ingredients

Sift in flour, cocoa powder, salt, and baking powder. Mix gently until just combined. Do not overmix to keep brownies fudgy.

Step 4 – Prepare Peanut Butter Mixture

In a separate bowl, slightly warm the peanut butter and mix with powdered sugar until smooth and spreadable.

Step 5 – Assemble the Brownies

Pour the brownie batter into the prepared pan. Drop spoonfuls of peanut butter on top and use a knife or toothpick to swirl it into the batter.

Step 6 – Bake

Bake for 30–35 minutes, or until the center is set but still slightly soft for fudgy texture.

Step 7 – Cool and Slice

Allow brownies to cool completely before cutting into squares. This helps them set properly.
