• 8 oz semi-sweet chocolate, chopped (use baking bars, not chips)
• ¾ cup all-purpose flour

• 1 tsp baking powder
• ¼ tsp salt
• 5 Tbsp unsalted butter, room temperature
• ¾ cup light brown sugar
• ¼ cup granulated sugar

How to Make Peanut Butter Filled Brownie Cookies

Start by making the filling and freezing it—this keeps the peanut butter from melting too quickly in the oven. Then prepare the rich brownie-style cookie dough. You’ll chill both before assembling, which helps keep the cookies structured and their centers melty but not messy.

STEP-BY-STEP INSTRUCTIONS:

Step 1: Prepare the Peanut Butter Centers
In a medium bowl, mix together the creamy peanut butter and powdered sugar. The mixture should be smooth but firm enough to shape. Roll into 24 small balls (about 1 teaspoon each). Place them on a parchment-lined plate or tray, and freeze for at least 1 hour. This helps them hold shape during baking and keeps the filling gooey.

Step 2: Make the Cookie Dough
Melt the chopped chocolate gently—use a double boiler or microwave in 15-second bursts, stirring in between. Set aside to cool slightly.

In a separate bowl, whisk together flour, cocoa powder, baking powder, and salt.

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

Slowly pour in the melted chocolate and mix until well combined. Stir in the dry ingredients just until the dough comes together. It will be sticky and thick.

Cover the bowl and refrigerate for at least 1 hour to firm up the dough.

Step 3: Assemble the Cookies
Scoop out about 1½ tablespoons of cookie dough. Flatten it in your hand, then place a frozen peanut butter ball in the center. Gently fold the dough around the filling, sealing it completely, and roll into a ball.

Place each cookie on a parchment-lined baking sheet, spaced 3 inches apart. You may need to bake in batches.

Step 4: Bake to Perfection
Preheat your oven to 350°F (177°C). Bake cookies for 12–13 minutes or until the edges are set and the tops begin to crack. Don’t overbake—they’ll continue to cook as they cool.

Let the cookies cool on the baking sheet for about 10 minutes before transferring them to a wire rack.

Helpful Tips

• Freeze the Filling First: This prevents it from melting too quickly and helps keep that beautiful molten core.
• Use Quality Chocolate: Chocolate bars (like Ghirardelli or Baker’s) melt better and provide richer flavor than chocolate chips.
• Don’t Skip the Chill: Chilling the dough makes it easier to handle and prevents cookies from spreading too much.
• Keep Hands Cool: If the dough gets too sticky to roll, wash and dry your hands with cold water, or lightly dust them with cocoa powder.
• Store at Room Temp: These cookies keep their best texture outside the fridge, in an airtight container.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?
Yes, but the texture inside will be less smooth. It still tastes amazing with a little crunch.

Why do I need to freeze the filling?
The frozen filling keeps the peanut butter from leaking or baking unevenly. It creates that gooey core when the cookie is fully baked.

How long will they stay fresh?
Up to 1 week at room temperature, though they rarely last that long.

Can I freeze them?
Absolutely. Freeze baked cookies or unbaked dough balls (already assembled) for up to 3 months. Bake straight from frozen, adding 1–2 minutes to the time.

Storage Instructions

• Room Temperature: Store in an airtight container for up to 7 days.
• Refrigerator: Optional but not required—will firm up the filling.
• Freezer: Freeze unbaked (assembled) cookies for later. Bake from frozen or thaw overnight before baking.
