Instructions

Preheat the oven to 350 degrees

Combine the flour, cocoa powder, baking soda, cornstarch, and salt in a medium bowl.

Stir with a whisk to combine.

Using a standing mixer, beat the butter and sugars until fluffy.

Beat in the eggs one at a time, mixing well after each addition.

Beat in the vanilla and Nutella.

Slowly add the flour mixture and mix just until combined. Fold in the M&M's.

Drop 1 tablespoon size balls of dough about 2-inches apart onto the prepared baking sheet.

Bake for 10 to 12 minutes or until edges look dry.

Cool on the pan for 5 minutes before transferring to a wire rack to cool completely.

Enjoy!!
