Soft, spiced oatmeal cookies with egg nog baked right into the dough, sandwiched with a rich egg nog buttercream. These festive cream pies are perfectly chewy, creamy, and full of cozy holiday flavor, a fun twist on the classic oatmeal cream pie!
In a large mixing bowl combine melted butter and sugars, whisk to combine. Add in the eggs, vanilla, and egg nog.
1 cup Unsalted butter, 1 cup Granulated Sugar, 1 cup Light brown sugar, 2 whole Eggs, 1 tbsp Vanilla extract, 1 tbsp AE Dairy Egg nog
Add the dry ingredients into the wet ingredients, mix well. Fold in the oats. Cover and chill dough for 1 hour.
2 cups Old-fashioned rolled oats
Preheat oven to 350 degrees F. Line a sheet pan with parchment paper and set aside.
Using a portion scoop, scoop even sized scoops of cookie dough - about 1 1/2 ounces each. Arrange evenly on a lined cookie sheet, leaving 2-3" between each cookie. Bake for 9-12 minutes until golden brown. Allow to cool for a few minutes on the sheet pan then transfer to a wire rack to cool completely.
Repeat in batches until all the dough is used. Let cookies cool completely before frosting.
For the Frosting:
In the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with a handheld electric mixer, beat the butter until light and fluffy, 4-5 minutes.
1 cup Unsalted butter
Add in 2 cups of powdered sugar, beat on low until fully incorporated then increase speed to medium. Add in two more cups of powdered sugar, and egg nog, beat on low speed again until the powdered sugar is incorporated.
If the frosting is too thick, thin with a little extra egg not. If it is too thin, add in additional powdered sugar until desired consistency is reached.
Pipe or spread the frosting between two cooled oatmeal cookies, sandwich and repeat. These are best enjoyed the same day, but will keep for 2-3 days in the fridge if stored in an airtight container.
Notes
Chill the dough: A short chill (30-60 minutes) helps the cookies hold their shape and stay chewy.
Watch the bake time: Pull the cookies when the edges are just set, they’ll finish setting as they cool, keeping the centers soft.
Use room temp butter: This helps the buttercream whip up light and fluffy.
Pipe or spread carefully: Add an even layer of buttercream to avoid it squishing out when sandwiched.
Let them rest: After assembling, chill the cream pies for 30 minutes to help them set for cleaner bites.
