If you love the nostalgic flavor of classic oatmeal cream pies but want to take it to the next level, then the Oatmeal Cream Pie Cake is your new dessert obsession. This cake captures the essence of the beloved snack — soft, chewy oatmeal cookies sandwiching a luscious cream filling — and transforms it into a moist, layered cake that’s perfect for celebrations or just satisfying your sweet tooth.
What Is Oatmeal Cream Pie Cake?
Oatmeal Cream Pie Cake is a creative dessert inspired by the popular oatmeal cream pie cookie. Unlike the handheld cookie version, this cake takes all the familiar flavors and textures and presents them in layers of moist oatmeal cake and creamy frosting. It’s rich, comforting, and incredibly satisfying with every bite.
The cake layers are packed with oats, cinnamon, and warm spices, while the filling and frosting are typically made from a fluffy cream cheese or marshmallow-based icing, replicating that classic sweet creaminess found inside the original pies.

Ingredients That Make Oatmeal Cream Pie Cake So Special
To make an oatmeal cream pie cake that truly honors the original, you’ll want a few key ingredients:
- Old-fashioned oats: These add texture and that signature oatmeal flavor.
- Flour and spices: Cinnamon, nutmeg, and sometimes a pinch of cloves bring warmth and depth.
- Brown sugar and molasses: These sweeteners contribute to the chewy, caramel-like notes.
- Butter and eggs: For richness and structure.
- Cream cheese or marshmallow fluff: The creamy filling and frosting base.
- Powdered sugar: To sweeten and thicken the frosting.
- Vanilla extract: Enhances all the flavors beautifully.
How to Make Oatmeal Cream Pie Cake: Step-by-Step Guide
Step 1: Prepare the Oatmeal Cake Layers
Start by mixing together your dry ingredients — oats, flour, cinnamon, baking soda, and spices — in one bowl. In another bowl, cream butter and sugars until light and fluffy, then add eggs and vanilla. Gradually combine the wet and dry ingredients, alternating with buttermilk for a moist, tender crumb.
Pour the batter into greased cake pans and bake at around 350°F (175°C) until a toothpick comes out clean. Once baked, allow the cakes to cool completely.
Step 2: Make the Creamy Filling and Frosting
For the iconic creamy filling, whip together softened cream cheese with powdered sugar and a bit of vanilla until smooth and fluffy. You can add marshmallow fluff if you want that classic “pie” sweetness and texture.
Step 3: Assemble the Cake
Once the cake layers have cooled, spread a thick layer of the cream filling between each layer. Frost the top and sides with the remaining cream cheese frosting. For added texture and decoration, sprinkle some toasted oats or chopped nuts on top.
Step 4: Chill and Serve
Chill the cake in the refrigerator for a few hours to let the flavors meld and the frosting set perfectly. This step helps the cake slice cleanly and enhances the overall taste experience.
Tips for the Perfect Oatmeal Cream Pie Cake
- Use old-fashioned oats rather than instant for better texture.
- Toast your oats lightly before mixing them into the batter for a nuttier flavor.
- Don’t skip chilling the cake — it makes a big difference in flavor and texture.
- Customize the filling by adding a hint of lemon zest or cinnamon for a unique twist.
- Try gluten-free oats and flour if you want a gluten-free version.
