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 prepare two baking sheets by lining them with parchment paper to prevent sticking and ensure easy cleanup.
  2. Mix Wet Ingredients: In a large mixing bowl, whisk together the melted butter and granulated sugar until smooth and well combined. Add the eggs and vanilla extract, continuing to whisk until the mixture is fully combined and slightly fluffy.
  3. Incorporate Dry Ingredients: Sift in the cocoa powder, flour, salt, and baking soda. Stir gently until a thick batter forms, then fold in the semi-sweet chocolate chips evenly throughout the batter.
  4. Shape Cookies: Use a tablespoon to scoop portions of the dough onto the prepared baking sheets, spacing each about 2 inches apart. Slightly flatten the dough balls with your fingers or the back of a spoon to help them bake evenly.
  5. Bake: Place in the oven and bake for 10-12 minutes, or until the edges are set but the centers remain soft and fudgy. Remove from oven and let cool on the baking sheets for 5 minutes.
  6. Cool Completely: Transfer the cookies to a wire rack to cool fully, which is essential to prevent the buttercream from melting when assembled.
  7. Prepare Buttercream: In a large bowl, beat the softened butter with brown sugar and powdered sugar until the mixture is light, fluffy, and smooth. Add vanilla extract and milk, mixing to combine well.
  8. Add Chocolate Chips: Fold in the mini chocolate chips into the buttercream evenly for a delightful texture and added chocolate bursts in each bite.
  9. Assemble Sandwiches: Once the cookies are completely cooled, spread a generous amount of the cookie dough buttercream onto the flat side of one cookie. Top with another cookie to form a sandwich. Repeat with the remaining cookies and buttercream.

Notes

  • Ensure cookies are completely cooled before assembling to avoid melting the buttercream.
  • You can store the sandwich cookies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
  • For a dairy-free version, substitute butter with a vegan alternative.
  • The buttercream can be adjusted in sweetness by altering the amount of powdered sugar.
  • Use high-quality cocoa powder for the best rich chocolate flavor.
