Oatmeal Cream Pie Layer Cake Ingredients
For the Cake Layers
• Flahavan’s Rolled Oats – Provides texture and moisture to the cake; substitute with quick-cooking rolled oats if unavailable.
• Milk – Hydrates the oats, contributing to the cake’s tenderness; almond milk can be a great dairy-free option.
• Molasses – Adds depth and richness to the flavor, enhancing the brown sugar notes; honey or maple syrup can work, but you may need to adjust the sweetness.
• Vegetable Oil – Ensures moisture and softness; can substitute with melted coconut oil or melted butter.
• All-Purpose Flour – Forms the cake’s structure; for a gluten-free version, use a 1:1 gluten-free flour blend.
• Baking Powder & Baking Soda – Essential leavening agents to help the cake rise.
• Ground Cinnamon – Infuses warmth and flavor; optional but highly recommended.
• Salt – Balances sweetness and enhances flavor.
• Unsalted Butter – Adds richness and should be softened; substitute with vegan butter for a dairy-free option.
• Dixie Crystals Extra Fine Granulated Sugar & Light Brown Sugar – Provides sweetness and moisture; adjust quantities based on your preferred sweetness.
• Taylor & Colledge Vanilla Bean Paste – Adds intense vanilla flavor with lovely specks; feel free to swap with vanilla extract.
• Large Eggs – Brings moisture and aids in leavening, ensuring a delightful rise.
For the Frosting & Filling
• Confectioners Sugar – Used in both the frosting and marshmallow filling for delightful sweetness and texture.
• Heavy Whipping Cream – Adds a creamy texture to the frosting; can be substituted with milk or a dairy-free cream.
• Marshmallow Creme or Marshmallow Fluff – Creates the signature filling for the Oatmeal Cream Pie Layer Cake; homemade is preferred, but store-bought works too.
For Garnish
• Pre-packaged Oatmeal Cream Pies – Adds a nostalgic touch and makes for a delightful garnish.
Step‑by‑Step Instructions for Oatmeal Cream Pie Layer Cake
Step 1: Prepare the Oats
Start by soaking the rolled oats in a bowl with the milk, molasses, and vegetable oil. Let this mixture sit for about 15 minutes, allowing the oats to absorb the liquid, which will create a moist base for your Oatmeal Cream Pie Layer Cake. The oats should plump up nicely, so you’ll know they’re ready.
Step 2: Preheat and Prepare Pans
While the oats soak, preheat your oven to 350°F (175°C). Prepare two 8-inch round cake pans by greasing them with butter or cooking spray and dusting them lightly with flour to prevent sticking. This will ensure your cake layers come out smoothly once baked, making for easier assembly later.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, and salt. This dry mixture will create the structure of your Oatmeal Cream Pie Layer Cake. Set it aside while you cream the butter and sugars; these ingredients should be well combined for a uniform batter.
Step 4: Cream the Butter and Sugars
Using a stand mixer or hand mixer, cream the softened unsalted butter with both the granulated and light brown sugars until the mixture is light and fluffy, about 3-5 minutes. Scrape down the sides of the bowl periodically for even mixing. This step is key to achieving that rich, moist texture in your cake.
Step 5: Incorporate the Eggs
Add the large eggs to the creamed butter and sugar mixture one at a time, mixing well after each addition. This process helps to blend in the moisture needed for the Oatmeal Cream Pie Layer Cake and ensures that the batter is airy. Continue mixing until there are no streaks of egg visible.
Step 6: Combine Mixtures
Slowly add the dry flour mixture and the soaked oats into the wet ingredients, alternating between them to maintain a smooth batter. Mix just until combined; be careful not to overmix, as this can lead to a dense cake. Once ready, divide the batter evenly between the prepared cake pans.
Step 7: Bake the Cakes
Place the filled cake pans into the preheated oven and bake for 30-35 minutes, or until a cake tester inserted in the center comes out clean. The cakes should be golden brown, and the edges will slightly pull away from the pan. Once baked, leave them to cool in the pans for about 10 minutes.
Step 8: Cool Completely
After 10 minutes, carefully transfer the cakes to a wire rack to cool completely. Allowing the cakes to cool prevents the frosting from melting later during assembly. As they cool, you can begin making the frosting and marshmallow filling, setting the stage for a delicious assembly.
Step 9: Make the Frosting
In a mixing bowl, whip the softened butter until it’s airy and fluffy. Gradually mix in the confectioners sugar and heavy whipping cream until well combined, adding the vanilla bean paste for an extra kick of flavor. Whip until the frosting is light and spreadable, perfect for layering on your Oatmeal Cream Pie Layer Cake.
Step 10: Prepare the Marshmallow Filling
For the signature filling, combine a portion of the prepared frosting with the marshmallow cream in a separate bowl. Add in a bit more confectioners sugar to achieve the right consistency; it should be light and spreadable but still hold its shape when layered. This filling will add delightful sweetness to your cake.
Step 11: Layer and Assemble the Cake
Level the cooled cake layers with a serrated knife if necessary, and slice each layer in half, giving you a total of four layers. Begin assembly by placing the first layer on a serving platter, spreading a layer of marshmallow filling, followed by a layer of frosting. Repeat this process until all layers are stacked.
Step 12: Frost and Garnish
After assembling, apply a crumb coat to seal everything in before chilling the cake for about 30 minutes. This helps to set the layers and makes final frosting easier. Then, finish frosting the Oatmeal Cream Pie Layer Cake with the remaining buttercream and decorate with crumbled oatmeal cream pies for added nostalgia and flair.

Make Ahead Options
These Oatmeal Cream Pie Layer Cakes are perfect for busy home cooks looking to save time! You can prepare the cake layers up to 24 hours in advance by baking them and then cooling completely before wrapping them tightly in plastic wrap and refrigerating. This method keeps them fresh and moist. The marshmallow filling can also be made ahead and stored in the refrigerator for up to 3 days.

This not only saves time but ensures that your cake is just as delicious when served!
Expert Tips for Oatmeal Cream Pie Layer Cake
- Proper Oat Soaking: Soaking the rolled oats ensures they absorb moisture, creating a tender cake. Don’t skip this step to maintain the right texture!
- Butter Temperature: Use fully softened butter for the frosting; this is essential for a smooth and creamy consistency. If it’s too hard, you risk a lumpy frosting.
- Don’t Overmix: Mix your batter until just combined. Overmixing can lead to a dense cake, so be gentle when folding in the dry and wet ingredients.
- Cool Completely: Let the cake layers cool completely before frosting. This prevents the frosting from melting and sliding off when you assemble your Oatmeal Cream Pie Layer Cake.
- Crumb Coat Benefits: Applying a crumb coat before chilling helps seal in crumbs and provides a smooth base for your final frosting layer, making for a beautiful finish.
How to Store and Freeze Oatmeal Cream Pie Layer Cake
Room Temperature: Keep the cake in an airtight container at room temperature for up to 3 days to maintain its softness and flavor.
Fridge: You can store the cake in the refrigerator for up to a week, simply cover it with plastic wrap or place it in an airtight container to prevent it from drying out.
Freezer: For longer storage, freeze individual slices of the Oatmeal Cream Pie Layer Cake in airtight containers or wrapped in plastic wrap for up to 2 months. Thaw in the fridge overnight before enjoying.
Reheating: To enjoy at room temperature, let the cake sit out for about 30 minutes after removing it from the refrigerator. Alternatively, you can warm individual slices briefly in the microwave for a cozy treat!
