How to Make Oatmeal Cream Pie Cake
-
Preheat the oven to 350°F (180°C) and prepare three 8-inch cake pans by lining the bottoms with parchment paper. This ensures a smooth release after baking.
-
Boil a pot of water, then add the quick-cook oats. Once stirred, remove from heat and cover the pot for 20 minutes, letting the oats cool to room temperature.
-
Whisk together the flour, baking soda, salt, cinnamon, and nutmeg in a bowl and set it aside. This mixture is key for achieving the perfect texture.
-
Beat the butter and both sugars in a stand mixer at medium speed for about 5 minutes until light and fluffy. Then add the vanilla, eggs, and sour cream, mixing until just combined.
-
Combine the cooled oats into the butter mixture, mixing until just combined. Carefully fold in the flour mixture until incorporated; the batter will be thick and hearty!
-
Divide the batter evenly into the prepared pans (approximately 600g each). Bake for 20-22 minutes, until a toothpick comes out with a few moist crumbs attached. Allow cooling in the pans on a wire rack.
-
Prepare the buttercream by beating unsalted butter in a stand mixer until light and fluffy. Gradually mix in powdered sugar on low speed, then increase the speed to medium, beating for about 3-5 minutes. Finally, add heavy cream, vanilla extract, and vanilla bean paste.
-
Assemble your cake by placing one layer on a cake stand. Spread 1 cup of frosting on top, then add the next layer. Alternate layers of cake and frosting, finishing with the top layer upside down for a smooth surface.
-
Frost the sides and top of the cake with the remaining vanilla frosting in an even layer. Set the cake aside while you prepare the glaze.
-
Heat the heavy cream on the stove or in the microwave, then pour it over the white chocolate chips. Stir until melted and combined, and optionally add white food coloring for a brighter glaze. Allow cooling slightly.
-
Glaze the cake by placing it on a wire rack with a pan underneath. Pour the glaze in the center and gently spread it to the edges, letting it drip down the sides. Allow to set, then decorate with crumbled oatmeal cream pie cookies.
Optional: Top with extra crumbled cookies for added texture and sweetness!

Make Ahead Options
These Oatmeal Cream Pie Cake layers are perfect for meal prep and can be made ahead to save you valuable time! You can prepare the cake layers up to 3 days in advance; simply cool them completely, wrap them tightly in plastic wrap, and refrigerate to maintain moisture. The frosting can also be made up to 24 hours ahead—just store it in an airtight container in the fridge to keep it fresh. When you’re ready to serve, let the cake layers come to room temperature, rewhip the frosting for fluffiness, and then assemble and glaze your cake. This way, you’ll enjoy a show-stopping dessert with minimal last-minute effort, and it will be just as delicious!

Expert Tips for Oatmeal Cream Pie Cake
-
Cool Oats Properly: Allow the cooked oats to cool completely before mixing them into your batter. This prevents the batter from becoming overly runny and ensures a better cake texture.
-
Accurate Measurements: Use a kitchen scale for measuring flour and other ingredients for consistent results. Too much flour can lead to a dry cake, while too little can make it too dense.
-
Room Temperature Ingredients: Ensure butter, eggs, and sour cream are at room temperature. This helps create a light, fluffy cake when you mix your batter.
-
Don’t Overmix: Gently fold in the flour mixture to avoid overworking the batter. Overmixing can lead to a tough texture instead of the fluffy Oatmeal Cream Pie Cake you desire.
-
Layer Evenness: When spreading the batter, try to keep the layers as uniform as possible. This ensures even baking and helps the layers stack perfectly when assembling the cake.
-
Let the Glaze Set: Allow the glaze to cool slightly before pouring it over the cake. This prevents melting the frosting and gives a beautiful, shiny finish!
How to Store and Freeze Oatmeal Cream Pie Cake
Room Temperature: Keep the Oatmeal Cream Pie Cake covered at room temperature for up to 3 days to maintain its moist texture and flavor.
Fridge: If you need to store it longer, refrigerate the cake for up to 5 days. Cover it with plastic wrap or an airtight container to prevent it from drying out.
Freezer: For longer storage, freeze the cake wrapped tightly in plastic wrap and then aluminum foil for up to 3 months. Thaw in the fridge overnight before serving.
Reheating: To enjoy leftovers, gently reheat individual slices in the microwave for about 15-20 seconds. This will revive the cake’s delightful texture and warming spices!
Oatmeal Cream Pie Cake Recipe FAQs
What type of oats should I use for the Oatmeal Cream Pie Cake?
Absolutely! For this recipe, quick cook oats are the best choice as they cook quickly and provide the right texture without making the cake too dense. Instant oats are not recommended since they may clump and not blend smoothly into the batter.
How should I store the Oatmeal Cream Pie Cake?
For optimal freshness, keep your Oatmeal Cream Pie Cake covered at room temperature for up to 3 days. If you plan to store it longer, wrap it tightly in plastic wrap and refrigerate for up to 5 days. Just make sure it’s in an airtight container to prevent it from drying out.
Can I freeze the Oatmeal Cream Pie Cake? How?
Yes, you can definitely freeze your cake! First, allow it to cool completely. Then, wrap it tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. This method will keep it good for up to 3 months. When you’re ready to enjoy it, thaw the cake in the fridge overnight, and it’ll be ready for serving!
Why is my cake dense after baking?
Very! A dense cake can be a bummer, but it’s often an easy fix. Ensure you’re not overmixing your batter once the flour is added—just fold it in until combined. And remember to measure your ingredients accurately; too much flour can make the cake heavy. Always use the spoon-and-level method (spoon flour into your measuring cup and level it off).
Is this cake suitable for people with nut allergies?
Yes! This Oatmeal Cream Pie Cake does not contain nuts, making it suitable for those with nut allergies. However, always check your ingredient labels, especially for any processed items like baking soda or chocolate, just to be on the safe side!
Can I use a different frosting for the Oatmeal Cream Pie Cake?
The more the merrier! While the vanilla buttercream pairs wonderfully with the cake, feel free to experiment with a cream cheese frosting or even a chocolate frosting for a different twist. Just keep the balance of flavors in mind so that the cake’s delightful spices still shine through!
