Total Time 27 minutes mins
- 1 cup (2 sticks) unsalted butter, softened
- 1 cup granulated sugar
- 1 cup packed brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 1/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1 cup mini marshmallows
- 1/2 cup chopped nuts (optional)
- For a fun twist, you can add peanut butter chips or white chocolate chips instead of semi-sweet chocolate chips.
- To keep cookies softer, store them in an airtight container with a slice of bread. The moisture from the bread will help maintain the cookie's texture!
- For more intense chocolate flavor, increase cocoa powder to 1 cup and decrease flour to 2 cups.
