Step 1

Preheat the oven to 375 degrees Fahrenheit. Grease a baking sheet or line it with parchment paper.

Step 2

In a large bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy, about 5-7 minutes. Beat in the eggs, one by one, followed by the vanilla.

Step 3

In a separate bowl, sift together the flour, cocoa mix, cocoa powder, salt, baking, soda, and baking powder. Gradually pour this mixture into the butter-sugar mixture and gently mix until well combined. Mix in the marshmallow bits and chocolate chips.

Step 4

Drop spoonfuls of dough onto the prepared baking sheet, allowing for 2 inches of space in between. Bake them for 10 to 12 minutes. Place the cookies onto a wire rack to cool. Serve and enjoy!
