  • 1 cup (2 sticks or 227g) butter, softened
  • 1 cup (200g) brown sugar, packed
  • ½ cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla
  • cups (187.5g) all-purpose flour
  • 3 cups (270g) old-fashioned oats
  • 1 teaspoon baking soda
  • 2 teaspoons cinnamon


  • ¾ cup (1 1/2 sticks or 170g) butter, softened
  • 3 cups (375g) confectioners' sugar
  • 1 jar (7 ounces) marshmallow creme
  • 1-3 tablespoons whole milk



  • In your stand mixer fitted with a paddle attachment, add the butter and sugars. Cream for 2-3 minutes or until they are fully incorporated and fluffy.
  • Add in the eggs and vanilla and mix until combined.
  • Turn the mixer off and add in the flour, oats, baking soda, and cinnamon.
  • With the mixer on low, mix until just combined.
  • Refrigerate for 30 minutes, or up to overnight.
  • When you are ready to bake the cookies, preheat oven to 350°F and prepare a baking sheet by lining it with parchment paper.
  • Use a cookie scoop (Mine holds about 1 1/2 tablespoons of batter) and drop dough onto the parchment-lined baking sheet about 2 inches between.
  • Bake for 8-10 minutes or until the edges are lightly golden. The top of the cookie may appear a little wet, but they will continue to bake out of the oven. You don't want the cookies raw, so make sure they bake for at least 8 minutes.
  • After allowing the cookies to slightly cool, move them to a cooling rack.


  • While the cookies are cooling, mix together the butter, sugar, and marshmallow creme.
  • Add enough milk to make the filling spreadable.
  • Spread filling on the bottoms of half the cookies and top with the remaining cookies.
