About the Ingredients
Water
Essential for hydrating the oats, giving them a soft texture that blends beautifully into the cake.
Quick-Cook Oats
These oats enhance the cake’s texture, providing a delightful chewiness that echoes the classic oatmeal cream pies.
All-Purpose Flour
The backbone of the cake, creating a tender crumb that’s essential for a moist and fluffy cake.
Ground Cinnamon
This warm spice adds a comforting flavor that elevates the entire cake experience.
Unsalted Butter
Room temperature butter is crucial for a fluffy batter, lending richness and depth to the cake and filling.
Granulated and Brown Sugar
A perfect duo, these sugars create the ideal balance of sweetness, while the brown sugar adds a hint of caramel flavor.
Tips & Tricks
Use Parchment Paper
Line your cake pans with parchment to ensure easy removal and to keep the layers intact.
Cool Oats Completely
Letting the oats cool completely prevents them from cooking the eggs when mixed, ensuring a perfectly moist cake.
Check Oven Temperature
Use an oven thermometer to ensure your oven is at the correct temperature for perfectly baked layers.
Level Your Cake Layers
Use a serrated knife to level the tops of the cakes before stacking, ensuring a stable and beautiful finish.
Pro Tips
- Room Temperature Ingredients: Having all your ingredients at room temperature helps them incorporate more easily, resulting in a smoother batter.
- Don’t Overmix: Gently fold in the dry ingredients to keep the cake light and fluffy.
- Let Cake Layers Cool: Allow the cake layers to cool completely before assembling to prevent the filling from melting.
- Decorate with Love: Add oatmeal cream pie cookies on top for a charming and delicious decoration.

Step-by-Step Instructions
Preheat and Prepare
Start by preheating your oven to 350°F (180°C) and lining three 8-inch cake pans with parchment paper for easy release.
Prepare the Oats
Boil water and stir in the quick-cook oats. Remove from heat, cover, and let sit for 20 minutes until they absorb all the liquid and cool completely.
Mix the Dry Ingredients
In a separate bowl, whisk together the flour, baking soda, sea salt, cinnamon, and nutmeg to create a well-blended dry mixture.
Create the Cake Batter
Beat the room temperature butter and sugars until light and fluffy. Incorporate the vanilla extract, eggs, and sour cream, then mix in the cooled oats. Gently fold in the dry ingredients until just combined.
Bake and Cool the Layers
Divide the batter evenly among the prepared pans and bake for 20-22 minutes, or until a toothpick inserted comes out with a few moist crumbs. Let them cool completely before frosting.
Delicious Variations
Chocolate Chip Oatmeal Cake
Add a cup of chocolate chips to the batter for a rich and indulgent twist on this classic flavor.
Spiced Apple Filling
Incorporate diced apples and a sprinkle of cinnamon into the cream filling for a fruity variation that’s perfect in the fall.
Nutty Addition
Fold in chopped nuts like walnuts or pecans into the cake batter for an extra crunch and flavor boost.
How to Store Oatmeal Cream Pie Cake
Refrigerator
Store any leftover cake in an airtight container in the refrigerator for up to 5 days to maintain freshness.
Freezer
You can freeze unfrosted cake layers wrapped tightly in plastic wrap for up to 3 months. Thaw before frosting.
Reheating
To enjoy a slice warm, microwave for about 15-20 seconds, just until warmed through.
