When my son was in high school, I would buy Little Debbie Oatmeal cookies every time I went to the store. His one friend was convinced I was buying them just for him. There’s just something that hits the spot when you eat a Little Debbie’s cookie!


Now think of the yumminess of that and take it up a notch! Homemade is even better! I wish I could reach through your computer screen and give one right now. It would make your day!

Oatmeal Cream Pie Cookies


  • For the Cookies:
  • ½ cup butter, at room temperature
  • 3/4 cup brown sugar
  • 1 large egg
  • 1 tablespoon molasses (optional)
  • 1 teaspoon vanilla
  • 3/4 cup flour
  • ½ teaspoon baking soda
  • 1/4 teaspoon cinnamon
  • 1 cup quick cooking oats
  • For the filling:
  • ½ cup butter
  • 1 cup powdered sugar
  • 7 ounces marshmallow fluff



  1. Preheat the oven to 350 degrees and line 2 sheet pans with parchment paper or spray pans with cooking spray.
  2. In a large bowl, cream the butter and brown sugar until smooth and combined. Add the egg, molasses, and vanilla and stir to combined. Scrape the sides of the bowl and add the remaining ingredients.
  3. Use a small cookie scoop to spoon 2 teaspoon sized rounds of dough 2” apart on the prepared cookie sheets. Bake one at a time in the preheated for about 9 minutes or until the edges are set and turning golden. The center of the cookie may still look wet. Remove from oven and allow to cool completely. Continue baking the remaining cookies and allow to cool completely.


  1. Cream the butter and powdered sugar together on medium speed in a large bowl using a hand mixer. Add the marshmallow fluff and stir until well combined. If needed, you can thin the frosting out slightly with a teaspoon or two of milk- be careful not to add to much though as this makes for a messy cookie. Spoon the cream in between two cookies of the same size. Alternatively, you can just spread large dollops on with a knife.
