Method
Make the peanut butter filling
- Stir the peanut butter and powdered sugar in a medium bowl until smooth and thick.
- Divide the filling into 18 rounded tablespoon portions and roll them into balls.
- Refrigerate the filling balls while you make the dough.
Make the chocolate cookie dough
- In a large bowl, beat the softened butter, brown sugar, and granulated sugar with an electric mixer on medium speed until creamy, about 2 minutes.
- Beat in the egg and vanilla.
- In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
- Mix the dry ingredients into the butter mixture on low speed just until no dry streaks remain.
- Cover and refrigerate the dough for 20 minutes.
Assemble and bake
- Heat the oven to 350°F and arrange racks in the upper and lower thirds.
- Line two 18x13-inch rimmed baking sheets with parchment paper.
- Divide the dough into 18 portions and flatten each into a disk.
- Place a peanut butter ball in the center of each disk and wrap the dough around it, pinching the seam closed.
- Arrange 9 cookies on each baking sheet, at least 2 inches apart.
- Bake for 10–12 minutes, swapping the sheets between racks and rotating them front to back halfway through, until the edges are set and the tops no longer look wet.
- Cool the cookies on the baking sheets for 10 minutes.
- Transfer the cookies to a wire rack to cool completely.
Notes
For sealed centers, pinch each dough seam closed before baking. Store in an airtight container at room temperature for up to 4 days; freeze for up to 2 months. For a gluten-free variation, use a 1:1 gluten-free all-purpose flour blend.
