Ingredients

Cookies:

  • 10 tablespoons of unsalted butter room temperature
  • ¼ cup granulated sugar
  • ½ cup dark brown sugar lightly packed
  • 1 teaspoon pure vanilla extract
  • 1 egg
  • ½ tablespoon molasses (if you don't have this on hand you can skip it)
  • ¾ cup all purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ teaspoon cinnamon
  • 2 cups of quick cooking oats

Filling:

  • 6 tablespoons unsalted butter room temperature
  • 1 cup marshmallow fluff
  • 1 cup powdered sugar
  • ½ teaspoon pure vanilla extract
  • pinch of salt

Instructions

For the cookies:

  • Preheat oven to 350 and line two baking sheets with silicone liners or parchment paper.
  • Beat butter and sugars for several minutes, until light and fluffy. Add in vanilla, egg and molassses and mix until combined.
  • In a separate bowl, whisk flour, baking soda, salt , cinnamon and oats until thoroughly combined.
  • Slowly add the dry ingredients into the butter mixture and mix until just combined.
  • Using a 1 ½ tablespoon scoop, drop the dough onto the prepared baking sheets, leaving a couple inches between the cookies for spreading.
  • Bake in preheated oven for approximately 10 minutes, until the edges look done and the centers are still slightly soft. Cool completely on the baking sheets set over a cooling rack.
  • Once the cookies have cooled, top the bottom side of half of the cookies with as much filling as you'd like, then place another cookie, top side up, on top of the filling.

For the filling:

  • Beat butter and marshmallow fluff for several minutes, until combined. Add powdered sugar, vanilla extract and salt and mix until smooth and creamy.

Notes

It’s important that all the cookies come out the same size so they are even when you sandwich them. For this, I suggest using a cookie scoop. I used a 1 ½ tablespoon scoop and my cookies came out at almost 3 inches across. Feel free to use a bigger or smaller scoop; just adjust the cooking time by a couple minutes. If you do play around with the size of these cookies, I would recommend going smaller, not bigger, because these are very rich
