Oatmeal Cream Pie Layer Cake Ingredients
• Here’s everything you need to recreate this nostalgic treat!
For the Cake
- Flahavan’s Rolled Oats – Adds chewiness and whole grain texture; substitute with quick-cooking oats if unavailable.
- Milk – Hydrates the oats and provides moisture to the batter; any milk or a non-dairy alternative can enhance flavor.
- Molasses – Contributes moistness and deep flavor; dark corn syrup can replace it for a slightly different taste.
- Vegetable Oil – Keeps the cake moist; can be swapped with melted coconut oil or canola oil for a different flavor.
- All-Purpose Flour – Provides structure for the cake; no direct substitution, but a gluten-free blend can work.
- Baking Powder & Baking Soda – Essential leavening agents for a light cake; do not substitute without adjustments.
- Ground Cinnamon – Adds warm spice; feel free to omit for a more neutral flavor.
- Salt – Enhances overall flavor; can be reduced or omitted if using salted butter.
- Unsalted Butter – Contributes richness; substitute with margarine for a dairy-free option.
- Dixie Crystals Granulated Sugar & Brown Sugar – Provides sweetness and moisture; any granulated sugar can be used, and brown sugar can be swapped for coconut sugar.
- Vanilla Bean Paste – Gives intense vanilla flavor; pure vanilla extract can be used but may lack deep flavor.
- Large Eggs – Binds ingredients and adds moisture; for an egg-free option, consider flax or chia eggs.
For the Frosting
- Heavy Whipping Cream – Adds creaminess to the frosting; can be replaced with milk or dairy-free cream for a lighter texture.
- Marshmallow Creme/Fluff – Creates the fluffy filling; homemade fluff can enhance flavor, while store-bought is convenient.
- Dixie Crystals Confectioners Powdered Sugar – Sweetens the frosting and helps achieve consistency; a substitute is not recommended due to textural differences.
For the Garnish
- Pre-Packaged Oatmeal Cream Pies – To decorate; can be replaced with homemade oatmeal cookies or left off for a simpler presentation.
Step‑by‑Step Instructions for Oatmeal Cream Pie Layer Cake
Step 1: Prepare the Oat Mixture
In a mixing bowl, combine 1 cup of Flahavan’s rolled oats with 1 cup of milk, 1/4 cup of molasses, and 1/2 cup of vegetable oil. Stir well to ensure the oats are fully coated, and then allow the mixture to sit for about 15 minutes. This step is crucial as it hydrates the oats, giving your Oatmeal Cream Pie Layer Cake the chewy texture we love.
Step 2: Preheat the Oven
While the oats are soaking, preheat your oven to 350°F (175°C). Prepare three 9-inch round cake pans by greasing them with butter or vegetable spray, followed by a light dusting of flour. This preparation will help the cake layers release easily once baked, ensuring a smooth assembly for your Oatmeal Cream Pie Layer Cake.
Step 3: Mix Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of baking soda, 1/2 teaspoon of salt, and 1 teaspoon of ground cinnamon. Make sure no lumps remain, and mix thoroughly. This dry blend is key to coating the wet ingredients evenly and allows your cake to rise beautifully during baking.
Step 4: Cream Butter and Sugars
In a stand mixer fitted with a paddle attachment, beat 1 cup of softened unsalted butter with 1 cup of granulated sugar and 1/2 cup of brown sugar on medium speed until the mixture becomes light and fluffy, about 3-5 minutes. Add 2 teaspoons of vanilla bean paste, blending until fully incorporated. This step adds a luscious richness to your Oatmeal Cream Pie Layer Cake.
Step 5: Incorporate Eggs and Mixtures
Add 3 large eggs to the butter mixture one at a time, mixing well after each addition. Gradually alternate adding the dry ingredients and the oatmeal mixture into the creamed butter, mixing on low speed until just combined and smooth. Avoid overmixing to keep your cake layers tender and fluffy, which will elevate the delight of your Oatmeal Cream Pie Layer Cake.
Step 6: Bake
Divide the batter evenly between the prepared cake pans and smooth the tops with a spatula. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Begin checking at 30 minutes to avoid overbaking, as we want the cake to remain moist and flavorful in your Oatmeal Cream Pie Layer Cake.
Step 7: Prepare Vanilla Bean Frosting
While the cakes are cooling, make the vanilla bean frosting. In a clean mixing bowl, beat 1 cup of softened unsalted butter until light and fluffy. Gradually add in 4 cups of confectioners’ sugar, along with 2 teaspoons of vanilla bean paste and 1/4 cup of heavy whipping cream, mixing until you reach a smooth, spreadable consistency that will beautifully cover the Oatmeal Cream Pie Layer Cake.
Step 8: Make Marshmallow Filling
In a separate bowl, combine 1 1/2 cups of the prepared frosting with 1 cup of marshmallow cream and an additional 1-2 cups of sifted confectioners’ sugar. Use a hand mixer to blend until you achieve a fluffy, creamy filling. This marshmallow filling adds that nostalgic flavor reminiscent of classic oatmeal cream pies, perfect for your cake layers.
Step 9: Assemble the Cake
Once the cake layers are completely cooled, level off the tops if needed. Place one layer on a serving platter, then spread a layer of marshmallow filling over the surface. Repeat this process with the second layer, adding more filling, and finally place the third layer on top. Apply a thin crumb coat of frosting around the sides before chilling for about 30 minutes to set.
Step 10: Final Frosting and Garnish
After chilling, remove the cake from the refrigerator and apply a generous layer of the vanilla bean frosting over the entire cake. Decorate with decorative swirls if desired, and top with pieces of pre-packaged oatmeal cream pies for a stunning finish. Let the Oatmeal Cream Pie Layer Cake sit at room temperature for 10-15 minutes before serving, or chill slightly for a colder treat.
Expert Tips for Oatmeal Cream Pie Layer Cake
• Room Temperature Butter: Ensures proper mixing and contributes to a fluffy texture in your Oatmeal Cream Pie Layer Cake.
• Level Layers: Use a serrated knife to level your cake layers before assembly; this prevents a leaning cake and ensures uniform frosting.
• Avoid Overmixing: Mix until just combined when incorporating wet and dry ingredients; overmixing can lead to a dense cake texture.
• Test for Doneness: Insert a toothpick into the center of the cake; it should come out clean or with a few moist crumbs, not wet batter.
• Crumb Coat Chilling: After applying a crumb coat, chill the cake for at least 30 minutes to help the final frosting stick better and reduce crumbs.
• Customize Filling: Experiment with flavored buttercreams instead of marshmallow fluff if you prefer a different taste profile in your Oatmeal Cream Pie Layer Cake.
Storage Tips for Oatmeal Cream Pie Layer Cake
Room Temperature: Store the cake in a cool, dry place for up to 2 days; cover it lightly with plastic wrap to retain moisture.
Fridge: Keep any leftovers in an airtight container in the refrigerator for up to 5 days; the flavors will continue to meld beautifully.
Freezer: Freeze the Oatmeal Cream Pie Layer Cake by wrapping slices or the whole cake tightly in plastic wrap, then in aluminum foil. It can be frozen for up to 3 months.
Reheating: To enjoy frozen cake, thaw it overnight in the fridge; savor it at room temperature or warm it slightly in the microwave for a cozy treat!

Oatmeal Cream Pie Layer Cake Recipe FAQs
What type of oats should I use for this cake?
I recommend using Flahavan’s rolled oats for their chewiness and whole grain texture in the Oatmeal Cream Pie Layer Cake. If you don’t have them, quick-cooking oats can work too, but they might alter the texture slightly.
How should I store leftovers?
Store the cake in an airtight container in the refrigerator for up to 5 days. If you leave it at room temperature, it should be consumed within 2 days. To keep it fresh, loosely cover it with plastic wrap to prevent it from drying out.
Can I freeze the Oatmeal Cream Pie Layer Cake?
Absolutely! You can freeze the whole cake or individual slices. Just wrap it tightly in plastic wrap, then in aluminum foil. It can be frozen for up to 3 months. When you’re ready to enjoy it, thaw it in the fridge overnight, and it will taste as delightful as when it was freshly baked!
What if my cake is too dry or crumbly?
If your cake turns out dry, ensure you’re measuring flour correctly; too much can lead to a dense texture. Also, be careful not to overbake it; keep an eye on the baking time and use the toothpick test. If it’s already baked, consider serving it with a scoop of ice cream to add moisture and flavor!
Are there any dietary considerations for this recipe?
For those with dietary restrictions, you can substitute the eggs with flax or chia seeds to make it egg-free. Also, use gluten-free flour to make the cake gluten-free. If you’re concerned about dairy, go for non-dairy alternatives like coconut or almond milk, and use margarine instead of butter.
What can I do if I don’t like marshmallow filling?
Feel free to switch the marshmallow filling with a flavored buttercream or a cream cheese frosting instead! This adds a different taste to your Oatmeal Cream Pie Layer Cake while maintaining that lovely moistness and creaminess.
