Christmas colored cookie sandwiches with marshmellow filling

Merry Christmas! OMG its finally here! Christmas day and before I open my presents  and gain a few ten pounds I figured in case of any last minute surprise party you will be having I will put some recipes up.I know it is Christmas and its cold in winter but U am going to talk about summer just for like 2 minutes k....kk great.At my pool in the snack bar they have chocolate chip cookie sandwiches.The filling is ice cream covered in chocolate chips but it is my favorite thing at the snack bar (I also  like the mini Ben&Jerrys cups of cookie dough ice cream). This is the same idea but it is freezing out and I don't want to get in trouble for making you sick so I am using a different recipe that has icing.The cake are yellow but it uses red, green, and white sprinkles to make it Christmas(If you celebrate another holiday you can add those colors instead)To be honest this is pretty much a whoppie pie.,Well it is a whoppie pie because the "cookies"  are actually cake.That's right this uses a yellow cake mix so it is a soft amazing dessert that will make you sing Christmas carols all day.Well I guess it is a mix of cookie and cake because it is a yellow cake flavored cookie and you use cake mix but once you read the directions you will see what I mean.K I'm bored lets change the subject to filling.When I was like 6-8 years old I love peanut butter and fluff sandwiches.One of my BFFs Emily also loved this so we used to eat it for lunch whenever we had a playdate.Well one day we stopped buying it and I really to this day have no idea why but I bought it again for the holidays are it gave me this.The moist cake and the filling are so creamy and heaven and OMG  my mouth is seriously watering talking about it.Well I want to rap our conversation up so I can open my presents so bye and MERRY CHRISTMAS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Ingredients
For the cake
1 yellow cake mix
1/2 cup butter, softened
2 tablespoons oil
2 eggs
1 teaspoon vanilla
1/2 teaspoon butter extract
1/4 cup Christmas sprinkle

For the cream filling:
5 tablespoons butter, softened
1/2 cup marshmallow fluff
2 cups powdered sugar
1 teaspoon vanilla
1 tablespoon heavy whipping cream
1 tablespoon sprinkles

Directions-
Preheat oven to 350 degrees. Place all cookie ingredients except sprinkles in a mixer bowl and mix on medium speed until combined. Stir in sprinkles.
Put drops of cookie dough onto cookie sheets lined with parchment paper. Bake for 6-8 minutes, until cookies have browned ever so slightly on the bottoms. Cool completely before filling.
To make filling: cream butter in a large bowl with an electric mixer. Beat in fluff until combined with the butter. Slowly mix in the powdered sugar until it has a crumbly, pea-sized texture. Add vanilla and heavy whipping cream and beat until frosting forms. Stir in sprinkles.
Frost the bottom of half of the cookies, and top with a second cookie.
Serve and enjoy!!!!!!!!!!!
