Ingredients

Oatmeal Cookies

  • 1 cup  margarine
  • 3/4 cup dark brown sugar
  • 1/2 cup sugar
  • 1 teaspoon  vanilla
  • 2 large eggs
  • 1 1/2 cups all purpose flour
  • 1/2 teaspoon salt
  • 1 teaspoon  baking soda
  • 1/4 teaspoon cinnamon
  • 1 1/2 cups quick oats

Cream Filling

  • 4 teaspoons very hot water
  • 1/2 teaspoon salt
  • 14 ounce jar marshmallow cream
  • 1 cup shortening
  • 2/3 cup powdered sugar
  • 1 teaspoon vanilla

Instructions

  • To make your Homemade Oatmeal Cream Pies, preheat oven to 350 degrees and line your cookie sheet pans with parchment paper. 
  • Grab a large mixing bowl and cream together the margarine, brown sugar, white sugar, vanilla, and eggs. Combine the flour, salt, baking soda, and cinnamon and add to the sugar mixture. Stir in the oats and drop dough one tablespoon at a time on your prepared baking cookie sheet pans. Bake for 11 - 13 minutes. They will spread out a bit and will appear undercooked when you remove them from the oven. Let them sit on the pan for 1 minute before moving them gently to a baking rack to cool. 
  • Once the oatmeal cookies are completely cool, make the marshmallow filling. In small bowl, dissolve the salt in the hot water and set aside to cool while you make the rest of the filling. In a large mixing bowl, combine marshmallow cream, shortening, powdered sugar, and vanilla. Beat mixture 1 - 2 minutes or until fluffy. Add the cooled salt water and mix well until incorporated. Spread filling on flat side of one cookie and press second cookie on top. 

Notes

Homemade Oatmeal Cream Pies can be stored in an airtight container within the refrigerator for up to 3 days.
The Cream Filling measurments listed is for a double batch of filling.  I really like filling.  The original recipe from Genius Kitchen only makes half the amount so for a more accurate representation of Little Debbie Oatmeal Cream Pies, feel free to cut my recipe for the filling in half.
