Ingredients
- For the Brownie Cookies:
- 1 cup semisweet chocolate chips
- ¼ cup unsalted butter
- 2 large eggs
- ¾ cup granulated sugar
- 1 teaspoon vanilla extract
- ¾ cup all-purpose flour
- ¼ cup unsweetened cocoa powder
- 1 teaspoon baking powder
- ¼ teaspoon salt
- For the Fluffy Peanut Butter Filling:
- ½ cup creamy peanut butter
- ¼ cup unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- 2 to 3 tablespoons heavy cream or milk
- Pinch of salt
Instructions
1. Prepare the Cookie Dough
Preheat the oven to 350°F (175°C). Melt the chocolate chips and butter together until smooth and let cool slightly.
Whisk the eggs and sugar until light and fluffy. Stir in the vanilla and melted chocolate mixture.
2. Add the Dry Ingredients
Whisk together the flour, cocoa powder, baking powder, and salt. Fold into the chocolate mixture until just combined.
3. Bake the Cookies
Drop tablespoon-sized portions onto parchment-lined baking sheets, leaving space between each cookie. Bake for 9 to 11 minutes until the tops are shiny and crackled. Allow the cookies to cool completely.
4. Make the Peanut Butter Filling
Beat the peanut butter and softened butter until creamy. Gradually add the powdered sugar, vanilla, salt, and enough cream to create a light, fluffy frosting.
5. Assemble the Sandwich Cookies
Spread or pipe a generous amount of peanut butter filling onto the flat side of one cookie and sandwich with another cookie.
6. Serve
Allow the cookies to rest for 15 minutes before serving so the filling can set.
Expert Tips
Don't overbake the cookies—they should still look slightly soft in the center for the best fudgy texture. Cool the cookies completely before filling to prevent the frosting from melting. Pipe the filling for a bakery-style finish.
Storage
Store the assembled cookies in an airtight container at room temperature for up to 3 days or refrigerate for up to one week. Freeze for up to 2 months and thaw before serving.
Serving Suggestions
Serve with a cold glass of milk, hot coffee, espresso, or vanilla ice cream. They're also a fantastic addition to holiday dessert platters or gift boxes.
Recipe Variations
Mix mini chocolate chips into the filling, drizzle the cookies with melted dark chocolate, use crunchy peanut butter for added texture, or replace the filling with marshmallow frosting, Nutella buttercream, or cookies-and-cream frosting.
