- 3 large eggs (room temperature)

- 2 1/2 cups unsalted butter (room temperature)
- 4 cups powdered sugar
- 2 tbsp heavy cream
- 2 tsp vanilla extract

How to Make Oatmeal Cream Pie Cake
Step 1: Preheat the Oven
Preheat your oven to 350 F (180 C). Line three 8-inch cake pans with parchment paper on the bottoms. Set them aside while you prepare the batter.
Step 2: Prepare the Oats
Bring a pot of water to a boil. Add in the oats, stir well, then remove from heat. Cover the pot for about 20 minutes until the oats are soft. Let them cool to room temperature before using.
Step 3: Mix Dry Ingredients
In a mixing bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg until well combined. Set aside.
Step 4: Make the Batter
In a stand mixer, beat together butter and sugars on medium speed for about five minutes until light and fluffy. Add in vanilla extract, eggs, and sour cream; mix until everything is combined. Scrape down the sides as needed.
Step 5: Combine Ingredients
Mix in the cooled oats until just combined. Carefully fold in your dry mixture until you have a thick batter.
Step 6: Bake the Cake Layers
Evenly distribute the batter into your prepared pans (about 600g each). Bake for about 20–22 minutes or until a toothpick inserted comes out with moist crumbs attached. Allow cooling in pans on a wire rack before flipping them out.
Step 7: Make Buttercream Frosting
In your stand mixing bowl, beat room-temperature butter until fluffy. Gradually add powdered sugar on low speed until combined. Increase speed to medium; beat until light and airy—about three to five minutes. Mix in heavy cream, vanilla extract, and vanilla bean paste.
Step 8: Assemble Your Cake
Place one layer of oatmeal cake on a serving stand. Spread one cup of frosting on top before adding another layer of cake. Alternate layers of cake and frosting finishing with the top layer upside down for stability.
Step 9: Frosting Application
Apply remaining frosting around the sides and top of your cake in an even layer. Set aside while you prepare your glaze.
Step 10: Prepare Glaze
Heat heavy cream on low heat either on the stove or microwave until warm. Pour over white chocolate chips; stir gently to combine until smooth. If desired, add white food coloring to achieve a brighter glaze appearance.
Step 11: Glaze Your Cake
Place your assembled cake on a wire rack with a pan underneath it. Pour glaze over center allowing it to drip down sides evenly. Once set, decorate top with crumbled oatmeal pie cookies as desired.
With these steps completed, you’ll have created an exquisite Oatmeal Cream Pie Cake that’s sure to impress!

How to Perfect Oatmeal Cream Pie Cake
To ensure your oatmeal cream pie cake turns out perfectly every time, consider these helpful tips.
-
Use room temperature ingredients: Bringing butter, eggs, and sour cream to room temperature helps them mix better, creating a smoother batter.
-
Measure flour correctly: Spoon flour into your measuring cup rather than scooping directly from the bag to avoid packing it down, which can lead to dry cake.
-
Don’t overmix the batter: Mix just until combined after adding dry ingredients. Overmixing can create a dense texture instead of a light one.
-
Cool cakes properly: Let the cakes cool in their pans for about 10 minutes before transferring them to wire racks. This prevents sticking and ensures even cooling.
-
Let frosting set: Allow your buttercream to rest slightly after mixing. This gives it time to firm up, making it easier to spread.
-
Chill before glazing: If the frosting is too soft, chill the assembled cake briefly before pouring on the glaze for a cleaner finish.
Best Side Dishes for Oatmeal Cream Pie Cake
Pairing side dishes with oatmeal cream pie cake can elevate your dessert experience. Here are some delightful options:
-
Fresh Berries: A mix of strawberries, blueberries, and raspberries adds freshness and tartness that balances sweetness.
-
Fruit Salad: A light fruit salad can provide refreshing contrast to the richness of the cake while adding vibrant colors.
-
Cheese Platter: Include soft cheeses like brie or goat cheese for a savory option that complements the sweet flavors of the cake.
-
Chocolate Covered Pretzels: The salty crunch of pretzels dipped in chocolate offers a fun textural contrast when served alongside.
-
Spiced Nuts: Roasted spiced nuts bring warmth and crunch; they also enhance the spiced notes in the oatmeal cake.
-
Mini Cheesecakes: Serving small cheesecakes provides another creamy dessert option that pairs nicely without overpowering.
-

Pumpkin Spice Latte: For an autumn twist, serve this classic beverage alongside your cake to enhance its comforting flavors.
Common Mistakes to Avoid
Baking can be tricky, especially with a delightful recipe like oatmeal cream pie cake. Here are some common mistakes to watch out for.
- Measurement Errors: Always double-check your ingredient measurements. Using too much or too little flour can affect the cake’s texture.
- Skipping Room Temperature Ingredients: Make sure your butter, eggs, and sour cream are at room temperature. This ensures better mixing and a fluffier cake.
- Not Cooling Oats Properly: Letting the oats cool completely before mixing is essential. If they’re too hot, they can alter the batter consistency.
- Overmixing Batter: When combining the flour mixture with wet ingredients, mix just until combined. Overmixing can lead to a dense cake.
- Ignoring Baking Time: Keep an eye on baking times! Every oven is different; check for doneness with a toothpick as soon as the minimum time is up.
