How to Make Oatmeal Cream Pie Cake
-
Preheat oven: Begin by preheating your oven to 350°F (180°C). Prepare three 8-inch cake pans by lining the bottoms with parchment paper, ensuring an easy release later.
-
Prepare oats: In a pot, bring 2 1/2 cups of water to a boil. Add the quick cook oats, stir them well, then remove from heat. Cover and let it sit for 20 minutes until cool.
-
Mix dry ingredients: In a bowl, whisk together 2 2/3 cups flour, 2 teaspoons baking soda, 1 teaspoon salt, 1 tablespoon plus 1 teaspoon cinnamon, and 1/2 teaspoon nutmeg. Set aside to combine the flavors.
-
Cream butter and sugars: In a stand mixer, beat 1 cup of unsalted butter with 1 cup granulated sugar and 1 cup packed light brown sugar on medium speed for about 5 minutes, until it becomes light and fluffy.
-
Incorporate wet ingredients: Add 1 tablespoon vanilla extract, 3 large room temperature eggs, and 1/4 cup full-fat sour cream to the butter mixture. Mix until fully combined, scraping down the bowl as needed.
-
Combine oats and flour: Stir in the cooled oats until just incorporated. Then, gently fold in the dry flour mixture until just combined. It will be quite thick—don’t fret!
-
Bake the cakes: Divide the batter evenly among the prepared pans (about 600g each). Bake for 20-22 minutes or until a toothpick inserted comes out with moist crumbs. Cool in pans before transferring to wire racks.
-
Make the frosting: In the stand mixer, beat 2 1/2 cups unsalted butter until light and fluffy. Gradually add 4 cups powdered sugar. Once combined, increase speed to medium and beat for about 3-5 minutes. Add 2 tablespoons heavy cream, 2 teaspoons vanilla extract, and 1 teaspoon vanilla bean paste.
-
Assemble the cake: On a cake stand, place one layer of cake and spread 1 cup of the frosting on top. Continue alternating layers and frosting, finishing with the top layer placed upside down for a flat surface.
-
Frost the cake: Use the remaining frosting to cover the sides and top of the cake smoothly. Set it aside while preparing the glaze.
-
Prepare the glaze: Heat 1/4 cup plus 3 tablespoons heavy cream, pour it over 1 cup of white chocolate chips, and stir until melted and smooth. If desired, add white food coloring for a brighter finish. Allow it to cool slightly.
-
Glaze the cake: Place the cake on a wire rack over a pan. Pour the glaze in the center and gently spread it to the edges, letting excess drip off. Once set, decorate with crumbled oatmeal cream pie cookies.
