- Nutmeg – Offers a warm, aromatic quality; allspice can be a suitable substitute for this ingredient.
- Baking Soda – Helps your cake rise beautifully; always check for freshness to ensure effectiveness.

Step‑by‑Step Instructions for Oatmeal Cream Pie Cake
Step 1: Preheat and Prepare Pans
Preheat your oven to 350°F (180°C) and line three 8-inch cake pans with parchment paper. This ensures easy release and helps your Oatmeal Cream Pie Cake come out perfectly. Grab your kitchen scissors to cut the parchment to size for each pan.
Step 2: Prepare the Oatmeal
In a medium saucepan, bring 2 cups of water to a boil. Once boiling, stir in 2 cups of quick-cook oats, cover, and remove from heat. Allow the oats to hydrate for about 20 minutes. You’ll know it’s ready when the oats are plump and have absorbed most of the water.
Step 3: Combine Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of fine sea salt, 2 teaspoons of ground cinnamon, and ½ teaspoon of nutmeg. Setting the dry ingredients aside will help ensure an even texture in your Oatmeal Cream Pie Cake.
Step 4: Cream Butter and Sugars
Using a stand mixer, cream together ½ cup of unsalted butter, 1 cup of granulated sugar, and ½ cup of light brown sugar on medium speed for about 5 minutes. Look for the mixture to become light and fluffy. This step is crucial for creating a nice texture in your cake.
Step 5: Mix Wet Ingredients
Add 2 large eggs, 1 teaspoon of vanilla extract, and ½ cup of full-fat sour cream to the creamed butter and sugars. Mix until fully combined, ensuring the ingredients are thoroughly blended together. The rich flavors will combine to create a moist base for your Oatmeal Cream Pie Cake.
Step 6: Incorporate Oatmeal and Dry Mix
Gently fold in the prepared oatmeal into the wet mixture until well combined. Then, gradually add the dry ingredient mixture and stir until just combined. Be careful not to overmix; the batter should be thick and slightly lumpy, which is perfect for creating that soft texture.
Step 7: Divide and Bake
Divide the batter evenly among the three prepared cake pans. Smooth the tops with a spatula and bake in the preheated oven for 20-22 minutes. The cakes are done when a toothpick inserted into the center comes out with a few moist crumbs, indicating a tender crumb.
Step 8: Cool the Cakes
Once baked, remove the pans from the oven and allow the cakes to cool in the pans for about 10 minutes. Carefully turn them out onto wire racks to cool completely. This step is essential for easy assembly and prevents the layers from being too soft.
Step 9: Prepare the Filling
In a mixing bowl, beat ½ cup of unsalted butter until fluffy. Gradually add 3-4 cups of powdered sugar, mixing well until combined. Then, mix in ¼ cup of heavy cream and 1 teaspoon of vanilla extract until the filling is airy and spreadable, perfect for layering inside your Oatmeal Cream Pie Cake.
Step 10: Assemble the Cake
Begin assembling by placing one layer of cake on a serving platter. Spread a generous layer of filling on top, then add the second layer and repeat. Place the final layer on top upside down for a flat surface, ensuring a level cake that’s ready for frosting.
Step 11: Frost and Glaze the Cake
Using the remaining vanilla filling, frost the sides and top of the assembled cake. For the glaze, melt 1 cup of white chocolate chips with ¼ cup of heavy cream over low heat until smooth. Let it cool slightly before pouring it over the cake, allowing it to cascade gently down the sides.
Step 12: Final Touches
Finish the Oatmeal Cream Pie Cake by garnishing it with crumbled oatmeal cream pie cookie pieces on top of the glaze. Allow the glaze to set before slicing. Your cake is now a beautiful centerpiece ready to delight your family and friends!

How to Store and Freeze Oatmeal Cream Pie Cake
Fridge: Store leftover Oatmeal Cream Pie Cake in an airtight container for up to 3-4 days to maintain its moisture and flavor.
Freezer: For longer storage, wrap individual slices tightly in plastic wrap or foil, then place them in a freezer-safe bag. They will keep well for up to a month.
Thawing: To enjoy frozen slices, simply transfer them to the fridge for several hours or overnight before serving; this helps retain the cake’s freshness.
Reheating: If you prefer a warm slice, gently microwave for 10-15 seconds; be careful not to overheat, as it can dry out the cake.
Expert Tips for Oatmeal Cream Pie Cake
- Measure Flour Wisely: Use the spoon-fluff method instead of scooping to prevent a dense cake; accurate flour measurement is crucial for success.
- Proper Room Temperature: Make sure your butter and eggs are at room temperature for better emulsification; this improves texture and helps ingredients blend seamlessly.
- Don’t Rush Cooling: Allow the cakes to cool completely before frosting; this prevents the frosting from melting and ensures clean layers.
- Avoid Overmixing: Once you add dry ingredients, mix until just combined; overmixing can lead to tough cake layers, which we want to avoid for this Oatmeal Cream Pie Cake.
- Chill the Glaze: Let your white chocolate glaze cool slightly before pouring; this keeps the frosting firm while allowing the glaze to beautifully cascade down the sides.

Oatmeal Cream Pie Cake Recipe FAQs
How do I choose the right oats for my Oatmeal Cream Pie Cake?
Absolutely! For the best results, stick with quick-cook oats, as they provide the right texture and moisture. If you can’t find quick-cook oats, instant oats can be used in a pinch, but be aware they might not give the same chewiness to your cake.
What’s the best way to store leftovers of Oatmeal Cream Pie Cake?
Very good question! To keep your cake fresh, store it in an airtight container in the fridge for up to 3-4 days. This helps maintain its moisture and flavor. If you find yourself with leftovers after that, you can always freeze individual slices!
Can I freeze Oatmeal Cream Pie Cake? If so, how?
Absolutely! To freeze your cake, wrap individual slices tightly in plastic wrap or aluminum foil to prevent freezer burn, then place them inside a freezer-safe bag. They can be stored in the freezer for up to a month. When you’re ready to enjoy, transfer a slice to the fridge and let it thaw for several hours or overnight.
What should I do if my cake is too dense?
If your cake turns out too dense, it may be due to overmixing the batter when adding the dry ingredients. For the perfect texture, mix until just combined. Also, ensure you measured your flour accurately; using the spoon-fluff method instead of scooping straight from the bag can prevent this issue.
Can I make any substitutions for the ingredients in my Oatmeal Cream Pie Cake?
Very much so! If you’re looking to adjust flavors or cater to dietary restrictions, you can substitute full-fat sour cream with Greek yogurt for a tangy twist. Additionally, if you’re avoiding dairy, margarine can replace unsalted butter, and using applesauce in place of sour cream reduces fats while keeping moisture. Always feel free to get creative!
