How to Make Oatmeal Cream Pie Cake
Follow these simple steps to prepare this delicious Oatmeal Cream Pie Cake:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare three 6-inch or two 8-inch cake pans by spraying them with baking spray and lining the bottoms with parchment paper for easy release.
Step 2: Combine the Dry Ingredients
In a bowl, grind the uncooked oats into fine crumbs. In another bowl, whisk together the ground oats, sifted cake flour, baking powder, baking soda, cinnamon, and salt. Set aside so it’s ready to mingle with our wet ingredients.
Step 3: Cream the Butter and Sugars
In a mixing bowl, cream the unsalted butter until it’s creamy and light. Add the vegetable oil, granulated sugar, and brown sugar. Mix on medium-high speed for about 2 minutes until it’s a fluffy cloud of goodness.
Step 4: Incorporate the Eggs and Milk
Add the eggs one at a time while mixing on low speed. Mix in the sour cream and vanilla extract, then beat on high for about 1 minute until everything is well combined and dreamy. Gradually add the dry ingredients, stopping to scrape down the sides of the bowl. Slowly add the milk, mixing gently until just combined.
Step 5: Bake the Cake Layers
Divide the batter between your prepared pans and pop them in the oven. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for about 5 minutes before transferring them to a wire rack to cool completely.
Step 6: Make the Frostings and Fillings
For the Marshmallow Creme Filling, whip the butter until smooth and then mix in the powdered sugar. Add the marshmallow creme, vanilla extract, and a pinch of salt, mixing until uniform and perfectly chewy. For the Vanilla Buttercream Frosting, cream the room-temperature butter until light in color, then gradually mix in the powdered sugar. Next, add the vanilla, milk, and a pinch of salt. Mix until smooth and fluffy.
Assemble this masterpiece by leveling the cooled cake layers. Pipe a ring of buttercream around the edge of the first layer, fill it with half of your marshmallow filling, top with the next layer, and repeat. Finally, place the final layer upside down for a smooth top, apply a crumb coat of buttercream, and refrigerate for about 20 minutes before finishing with your frosting.
Decorate with crumbled Oatmeal Creme Pies and pipe some swirls on top. Place quartered Oatmeal Creme Pies between those beautiful swirls for the ultimate presentation. Slice that cake, serve, and watch everyone light up with delight!
