Ingredients for Oatmeal Cream Pie Cake
- 1 cup rolled oats
- 1 cup boiling water
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- 1 cup granulated sugar
- 1 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- 1 cup powdered sugar
- 1 tablespoon milk (or more for desired consistency)
- 1 teaspoon vanilla extract (for filling)
Directions
Begin by preheating your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
Pour the boiling water over the rolled oats in a bowl. Set aside to let the oats absorb the water for about 20 minutes.
In a medium bowl, whisk together the flour, baking soda, baking powder, ground cinnamon, and salt. Set aside.
In a large mixing bowl, cream the softened butter with granulated sugar and brown sugar until the mixture becomes light and fluffy.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Gradually mix in the buttermilk and the oat mixture until well combined.
Slowly add the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix.
Pour the batter evenly into the prepared cake pans. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, let the cakes cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
For the filling, whip together the powdered sugar, milk, and vanilla extract until you achieve a smooth and spreadable consistency.
Once the cakes are cool, spread the filling over the top of one cake layer. Place the second layer on top and spread more filling on the top.
You can also add extra filling between layers if desired, or spread some on the sides of the cake.
How to Serve Oatmeal Cream Pie Cake

You can garnish the cake with a sprinkle of cinnamon or a few chocolate chips for added flair. For a fun twist, consider serving it alongside a warm beverage, such as tea or coffee, to complement the cake’s comforting flavors.

Expert Tips for Oatmeal Cream Pie Cake
To ensure your oatmeal cream pie cake turns out perfectly, follow these expert tips. First, always measure your ingredients accurately; using a kitchen scale can help achieve precise measurements. When mixing your cake batter, avoid overmixing. Stir until just combined to maintain a light and fluffy texture.
Be mindful of the cooling process. Allow the cakes to cool completely before adding the filling, as this prevents the filling from melting or slipping off the layers. If your cake layers domed during baking, use a serrated knife to level them before assembling.
For added moisture and flavor, consider adding a touch of nutmeg or a splash of maple syrup to your batter. If you find the filling too thick, add a little more milk until it reaches your desired consistency. Lastly, if you’re keen on presentation, using a cake turntable makes decorating the cake much easier and more fun.

Variations of Oatmeal Cream Pie Cake
While the classic oatmeal cream pie cake is delightful on its own, you can easily adapt the recipe to suit your taste preferences. One popular variation is to add chocolate chips into the batter for a sweet surprise. You could also swap out the vanilla extract for almond extract for a different depth of flavor.
Adding nuts, such as chopped walnuts or pecans, can introduce a crunchy texture that contrasts beautifully with the soft cake and creamy filling. For a seasonal twist, incorporate dried fruits like raisins or cranberries into the batter.
