Servings: 12 servings

Ingredients

  • 1 cup unsalted butter softened
  • 1 cup granulated sugar
  • 1 cup brown sugar packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 2/3 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup chocolate chips
  • 1 cup buttercream frosting

Instructions

  • In a large mixing bowl, beat the softened butter with granulated and brown sugars until light and fluffy, about 3-4 minutes.
  • Add the eggs one at a time, beating well after each addition. Then mix in the vanilla extract.
  • In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt.
  • Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until combined. Avoid overmixing.
  • Using a spatula, gently fold in the chocolate chips.
  • Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats. Scoop dough by rounded tablespoons onto sheets, spacing 2 inches apart. Bake for 10-12 minutes or until edges are set but centers remain soft.
  • Remove cookies from oven and let cool on baking sheet for 5 minutes before transferring to wire rack to cool completely.
  • Spread about 1 tablespoon of buttercream frosting on the flat side of one cookie. Top with another cookie, pressing gently to sandwich. Repeat for all cookies.
  • Serve fresh or store properly for later enjoyment.

Equipment

  • Mixing bowls
  • Electric mixer or stand mixer
  • Measuring cups and spoons
  • Rubber spatula
  • Baking Sheets
  • Parchment paper or silicone baking mats
  • Cooling rack
  • Spoon or cookie scoop

Notes

  • Make sure butter is softened but not melted for perfect dough texture.
  • Do not overbake; remove cookies when edges are firm but centers soft.
  • Chill dough for 30 minutes before baking for thicker cookies and better flavor.
  • Use a piping bag or offset spatula to spread buttercream evenly.
  • Cookies and sandwiches freeze well; freeze halves or assembled sandwiches for later.
