Ingredients

Scale

Cookie Dough

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

For Dusting

  • 1/4 cup powdered sugar

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper and set them aside.
  2. Cream Butter and Sugars: In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until the mixture is light and fluffy, approximately 3-4 minutes.
  3. Add Eggs and Vanilla: Add the eggs one at a time to the butter and sugar mixture. Beat well after each addition for full incorporation. Stir in the vanilla extract.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt until well combined.
  5. Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined to avoid overmixing.
  6. Fold in Chocolate and Marshmallows: Gently fold in the semi-sweet chocolate chips and mini marshmallows with a spatula or wooden spoon until evenly distributed throughout the dough.
  7. Shape Cookies: Using a cookie scoop or tablespoon, drop rounded dough balls onto the prepared baking sheets, leaving about 2 inches of space between each cookie.
  8. Bake Cookies: Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers remain gooey. The cookies may appear slightly underbaked but will firm up as they cool.
  9. Cool on Sheets: Remove the cookies from the oven and let them cool on the baking sheets for 5 minutes.
  10. Transfer and Dust: Transfer the cookies to a wire rack to cool completely. Once cooled, dust them lightly with powdered sugar for an added touch of sweetness and presentation.

Notes

  • Do not overmix the dough to ensure a tender cookie texture.
  • Mini marshmallows melt slightly during baking to create gooey pockets inside the cookies.
  • Cookies will appear soft when removed from the oven but will firm up as they cool.
  • For best results, use freshly softened butter and room temperature eggs.
  • Store cookies in an airtight container to maintain softness.
