If you grew up loving the classic oatmeal cream pie cookies, you’re going to fall head over heels for the Oatmeal Cream Pie Cake — a delicious, moist cake that captures all the flavors and textures of those beloved pies, but in a big, sliceable form! This cake takes the nostalgic comfort of oatmeal cookies and the creamy, dreamy filling, then transforms them into a show-stopping dessert that’s perfect for birthdays, gatherings, or simply a special treat.
What Is Oatmeal Cream Pie Cake?
Oatmeal Cream Pie Cake is essentially an ode to the famous oatmeal cream pie cookie, made famous by brands like Little Debbie. Instead of individual cookies, this recipe layers tender, spiced oatmeal cake layers with a rich and fluffy cream filling that tastes just like the classic cream sandwiched between two oatmeal cookies.
This cake combines the chewy, cinnamon-spiced oatmeal flavor with a luscious, smooth filling, often a whipped vanilla buttercream or marshmallow fluff cream. The result is a moist, flavorful cake that’s both comforting and indulgent.
Key Ingredients That Bring This Cake to Life
To create the perfect Oatmeal Cream Pie Cake, you’ll need ingredients that replicate the classic cookie flavors and creamy filling:
- Old-fashioned rolled oats: For that chewy, hearty oatmeal texture.
- Flour and baking soda: To give the cake structure and rise.
- Warm spices: Cinnamon and nutmeg are essential to evoke that nostalgic oatmeal pie flavor.
- Brown sugar and white sugar: Brown sugar adds moisture and a deep caramel note, while white sugar balances the sweetness.
- Butter and eggs: Provide richness and tenderness.
- Vanilla extract: For a warm, sweet aroma.
- Cream filling: Usually a combination of butter, powdered sugar, vanilla extract, and sometimes marshmallow fluff or cream cheese for creaminess.
How to Make Oatmeal Cream Pie Cake: Step-by-Step
Step 1: Prepare the Oatmeal Cake Layers
Start by mixing your dry ingredients — flour, oats, baking soda, cinnamon, and nutmeg — in one bowl. In a separate bowl, cream together the butter and sugars until fluffy, then add eggs and vanilla. Gradually mix the dry ingredients with the wet, creating a thick, oatmeal batter.
Pour the batter into greased cake pans and bake at 350°F (175°C) for about 25-30 minutes or until a toothpick inserted comes out clean. Let the layers cool completely before assembling.
Step 2: Make the Cream Filling
While the cake cools, prepare the creamy filling. Beat softened butter with powdered sugar and vanilla until smooth and fluffy. For extra creaminess and that classic “cream pie” texture, fold in marshmallow fluff or cream cheese. Whip until light and airy.
Step 3: Assemble the Cake
Place one oatmeal cake layer on your serving plate, then generously spread the cream filling on top. Add the second cake layer and cover the entire cake with the remaining cream filling or frosting. You can add extra oats or a light dusting of cinnamon on top for decoration.
Step 4: Chill and Serve
Chill the cake for at least an hour to let the filling set and flavors meld. This also makes slicing easier and cleaner.
