Description

Delight in the rich and indulgent Brownie Cookie Sandwiches filled with creamy, chocolate-studded cookie dough buttercream. This easy-to-make dessert combines fudgy cocoa brownies baked as cookies with a luscious buttercream frosting, perfect for satisfying any chocolate lover’s craving.

Ingredients

Scale

Brownie Cookies

  • 1/2 cup unsalted butter, melted
  • 1 1/4 cups granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 cup semi-sweet chocolate chips

Cookie Dough Buttercream

  • 1/2 cup unsalted butter, softened
  • 1/4 cup brown sugar
  • 1/2 cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1 tablespoon milk
  • 1/2 cup mini chocolate chips

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper to prevent sticking and ensure even baking.
  2. Mix Wet Ingredients: In a large bowl, whisk together the melted butter and granulated sugar until smooth. Then add the eggs and vanilla extract, whisking until the mixture is fully combined and creamy.
  3. Combine Dry Ingredients: Stir in the cocoa powder, flour, salt, and baking soda until a thick batter forms, being careful not to overmix. Fold in the semi-sweet chocolate chips to distribute them evenly throughout the batter.
  4. Form Cookies: Using a tablespoon, scoop portions of the dough onto the prepared baking sheets, spacing each about 2 inches apart. Slightly flatten each dough ball to promote even baking and a uniform shape.
  5. Bake Cookies: Bake in the preheated oven for 10-12 minutes, or until edges are set but centers remain soft and fudgy. Remove from oven and allow to cool on the baking sheets for 5 minutes before transferring to a wire rack to cool completely.
  6. Prepare Buttercream: In a large bowl, beat the softened butter, brown sugar, and powdered sugar together until the mixture becomes light and fluffy. Add vanilla extract and milk, mixing until fully combined and smooth.
  7. Add Mini Chocolate Chips: Fold the mini chocolate chips into the buttercream gently to evenly distribute them without breaking them up.
  8. Assemble Sandwiches: Once the cookies are completely cool, spread a generous amount of cookie dough buttercream onto the flat side of one cookie. Top with another cookie to create a sandwich. Repeat this process with the remaining cookies to complete all sandwiches.

Notes

  • Ensure cookies are completely cooled before assembling to prevent the buttercream from melting.
  • You can store assembled sandwiches in an airtight container in the refrigerator for up to 3 days.
  • For a stronger chocolate flavor, use dark cocoa powder instead of unsweetened cocoa powder.
  • Scoop uniform-sized cookies for even baking and consistent sandwich sizes.
  • Buttercream can be made ahead and stored in the fridge; bring to room temperature and re-whip before using.
