Total Time 25 minutes

Equipment

Ingredients

  • 1 cup salted butter softened
  • ¾ cup granulated sugar
  • ¾ cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 2 cups all-purpose flour
  • 1 ½ cups lucky charms marshmallows only

Instructions

  • Preheat the oven to 350°F.
  • Use an electric hand mixer (or stand mixer) to whisk the butter and both sugars together for 3-5 minutes or until smooth and creamy.
  • Whisk in the egg and vanilla until the ingredients are just combined with the creamed sugar.
  • Add the baking soda and flour. Reduce the speed of your hand mixer to low and gently whisk in the dry ingredients until no clumps of dry flour remain in the cookie dough.
  • Fold in the lucky charms marshmallows until they are evenly distributed throughout the cookie dough.
  • Use a large cookie scoop (about 2 tablespoons in size) to form cookie dough balls and place on a baking sheet, leaving 2 inches between each dough ball. Bake for 10 minutes or until just golden.
  • Allow the cookies to cool for a few minutes before transferring them to a wire cooling rack.
  • Serve and enjoy!

Notes

Storage: Store these Lucky Charms cookies in an airtight container at room temperature for 6 days.
Freeze: The tasty treat cookies can be frozen in an airtight freezer bag for up to 2 months. When ready to serve, thaw them at room temperature!
TIPS:
  • Fold in the marshmallows so they do not get crushed.
  • The key to soft cookies is to not over-bake them! They should have crisp edges, but the tops of the cookies will look a little lighter in color. 
  • Remember that all ovens bake at different temperatures than the dial says, so watch your first batch or check the cookies around the 7-8 minute mark to see how they are baking in your oven. I love this oven thermometer to give mine a check from time to time.
