How to Make Peanut Butter Filled Brownie Cookies Step-by-Step

Start by preparing the peanut butter filling. In a medium mixing bowl, stir together peanut butter and confectioners’ sugar until it forms a thick, moldable consistency. Roll the mixture into small balls (about 1 heaping teaspoon each) and place them on a parchment-lined tray. Freeze for 1 hour.

Next, make the brownie cookie dough. Melt the butter and chocolate together in a microwave-safe bowl, heating in 30-second intervals and stirring between each until smooth. Allow the mixture to cool slightly. In a large bowl, whisk the melted mixture with both sugars, then beat in the eggs and vanilla extract.

Separately, whisk together the flour, cocoa powder, baking powder, and salt. Gradually combine the dry and wet ingredients to create a thick dough. Chill the dough for at least 30 minutes to make it easier to work with.

Preheat the oven to 350°F (177°C). Line baking sheets with parchment paper. Scoop about 1.5 tablespoons of cookie dough, flatten it, and place a frozen peanut butter ball in the center. Wrap the dough around the ball, sealing the edges completely, then gently roll it into a ball. Place on baking sheet, spaced 2 inches apart.

Bake for 12–14 minutes until edges are set. Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack.

Expert Tips for the Best Brownie Stuffed Cookies

• Chill for control: Both the peanut butter filling and the cookie dough should be chilled before assembly. This prevents sticky dough and makes wrapping easier.
• Use quality chocolate: Choose high-quality semi-sweet chocolate for a richer, more luxurious flavor.
• Seal with care: Ensure each peanut butter ball is fully enclosed in dough to avoid leaks.

Common Mistakes to Avoid When Baking These Cookies

• Skipping chill time: The dough will be too soft to handle without proper chilling.
• Overbaking: Remove cookies when the edges are just set—residual heat will finish the baking.
• Using natural peanut butter: It tends to be too oily and won’t hold its shape well inside the cookie.
