Homemade Oatmeal Cream Pie Recipe {Christmas Cookies}

I promised several of you that I would post this recipe before this weekend, so here you go! These homemade oatmeal cream pie cookies were the star of my Christmas cookie party last weekend. I found the recipe on Pinterest but tweaked a few ingredients to make it my own. 

One major change I made was to add cinnamon to the recipe. I actually didn't bake the cookies with the cinnamon in them because I didn't realize they needed cinnamon until after they were baked. So for my party last weekend, I simply sprinkled a cinnamon sugar mix on the top of the cookies. While that little mixture was good, I'm sure the cinnamon would be delish baked into the cookie!

I N G R E D I E N T S 
-3/4 cup all-purpose flour
-1/2 teaspoon baking soda
-1/2 teaspoon salt
-1/4 teaspoon baking powder
-1/2 cup butter, softened
-1/4 cup peanut butter
-1/2 cup granulated sugar
-1 tablespoon cinnamon 
-1/2 cup packed brown sugar
-1 egg
-1 teaspoon vanilla
-1 cup quick-cooking oats
-2 teaspoons hot water
-1/4 teaspoon salt
-1 7 ounce jar marshmallow creme
-1/2 cup shortening
-1/3 cup powdered sugar
 1. Preheat oven to 350 degrees F. Grease a cookie sheet; set aside. In a small bowl combine flour, baking soda, the 1/2 teaspoon salt, cinnamon and the baking powder; set aside. 
2. In a large bowl combine butter and peanut butter. Beat with an electric mixer on medium speed until combined. 
3. Beat in granulated sugar and brown sugar until fluffy. Beat in egg and vanilla just until combined. 
4. Stir in flour mixture and oats just until combined.
5. Drop dough by rounded teaspoons two inches apart onto prepared cookie sheet. Bake for 8 to 10 minutes or until edges are light brown and centers are set. Cool on cookie sheet for 1 minute. Transfer cookies to a wire rack; let cool.
6. Meanwhile, in a medium bowl combine the hot water and the 1/4 teaspoon salt. Stir until salt dissolves. Add marshmallow creme, shortening, and powdered sugar. Beat with an electric mixer on medium speed until combined.
7. Spread marshmallow mixture on the flat side of half of the cookies. Top each frosted cookie with another cookie, flat side down.

I hope some of you have a chance to make these this holiday weekend. They're the perfect Christmas cookie, so whip up a batch and enjoy them with your family!
