Ingredients

The following ingredients have 4 Servings
  • ¾ cup salted butter ( softened)
  • ¼ cup shortening
  • 1 cup light brown sugar
  • ¼ cup granulated white sugar
  • 2 large eggs
  • ¾ tsp vanilla extract
  • 1¾ cups all-purpose flour (spooned and leveled)
  • 1¼ tsp baking soda
  • ½ tsp allspice
  • 1¾ cups Old Fashioned oats
  • ¾ cup salted butter (softened)
  • 2½ cups powdered sugar
  • 1 tbsp whole milk
  • 7 ounce container marshmallow creme

Instruction

  • Line a sheet pan with parchment paper and preheat the oven to 350 degrees Fahrenheit.
  • To make the cookies, use a mixer to beat the salted butter, shortening, light brown sugar, and granulated white sugar until light and fluffy, about 3-5 minutes.
  • Add the eggs, and vanilla extract. Beat until fully combined and then scrape down the sides of the bowl and beat once more to make sure everything is mixed in.
  • Whisk together the all-purpose flour, baking soda, and allspice in a separate, large bowl.
  • Turn the speed on the mixer to low speed and add in the flour mixture and Old Fashioned Oats. Mix everything together until just combined.
  • Use a 1 ½ Tablespoon cookie scoop and scoop the batter onto the prepared sheet pan. Make sure to leave about 2 inches of space between each cookie.
  • Bake in the oven for 9-10 minutes, or until the edges have browned and the center has started to harden, and let cool for at least 10 minutes before assembling.
  • To make the filling, beat the salted butter, powdered sugar and milk together until it turns light and fluffy, about 2-3 minutes.
  • Fold in the marshmallow creme until completely combined.
  • Assemble the cookie (make sure the cookies are completely cooled) by piping or spooning the filling onto the bottom of one cookie and then topping it with another cookie, face up. Do this with all the cookies.
  • Serve and enjoy!
