Step‑by‑Step Instructions for Oatmeal Creme Pie
Step 1: Prepare the Oats
Start by soaking 2 cups of quick cooking oats in 2 cups of boiling water. Stir the oats well and let them rest for at least 30 minutes, allowing them to absorb the water and soften. This step is crucial for achieving that delightful texture in your Oatmeal Creme Pie cake.
Step 2: Preheat and Prep
While the oats are soaking, preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans with cooking spray and line the bottoms with parchment paper for easy cake removal. This will help ensure your layers bake evenly and slide out without any fuss.
Step 3: Cream the Butter and Sugars
In a large mixing bowl, cream together 1 cup of softened unsalted butter, 1 cup of granulated sugar, and 1 cup of packed brown sugar using an electric mixer on medium speed for about 4 minutes. The mixture should become light and fluffy, indicating it’s ready for the next ingredients.
Step 4: Incorporate Eggs and Molasses
Add 2 large room-temperature eggs, 1 tablespoon of vanilla extract, and ½ cup of dark molasses to the creamed butter and sugars. Mix on low speed until just combined, ensuring everything is well blended and the flavors meld together beautifully for your Oatmeal Creme Pie cake.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together 2 cups of flour (or gluten-free flour), 1 teaspoon of baking soda, 1 teaspoon of baking powder, ½ teaspoon of salt, 1 teaspoon of cinnamon, and ¼ teaspoon of ground cloves. Gradually add this dry mixture to the wet ingredients, mixing on low until just combined.
Step 6: Mix in Oats
Fold the soaked and cooled oats into the batter gently until fully incorporated. This will give the cake its characteristic lovely texture. Be careful not to overmix, as you want the batter to stay airy for a light Oatmeal Creme Pie cake.
Step 7: Bake the Layers
Divide the batter equally between the prepared cake pans. Bake in your preheated oven for 20-24 minutes, or until the tops are lightly golden and a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for about 10 minutes before moving on.
Step 8: Cool Completely
Carefully transfer the cakes to wire racks to cool completely. This will prevent the cake from becoming soggy, and you want perfectly fluffy layers for your Oatmeal Creme Pie. Let them cool to room temperature before assembling.
Step 9: Prepare the Filling
For the filling, whisk 2 egg whites and ½ cup of powdered sugar in a heatproof bowl over simmering water. Keep whisking until the mixture is warm to the touch, which takes about 5 minutes. This step ensures the egg whites are safe and adds stability to your filling.
Step 10: Mix Filling Ingredients
Remove the bowl from heat and mix in 1 teaspoon of vanilla extract, 1 ½ cups of heavy cream, and the remaining powdered sugar until you achieve a smooth consistency. This creamy filling brings that signature taste to your Oatmeal Creme Pie cake.
Step 11: Fold in Shortening
Switch to a paddle attachment on your mixer and fold in ½ cup of shortening. Mix on medium speed for about 4 minutes until the filling is light and fluffy. This will create that lovely texture that contrasts beautifully with the oatmeal cake layers.
Step 12: Assemble the Cake
Once the cakes are completely cooled, place one layer on a serving plate and spread a generous amount of filling on top. Gently place the second layer on top, pressing down slightly. You can also spread some extra filling on top of the second layer for a beautiful finish to your delightful Oatmeal Creme Pie.

Helpful Tricks for Oatmeal Creme Pie
-
Oat Soaking: Properly soak the oats for 30 minutes in boiling water to ensure they soften well and contribute to the cake’s moisture.
-
Temperature Matters: Use room temperature eggs and allow the soaked oats to cool before mixing to prevent cooking the eggs in the batter.
-
Mixing Technique: When incorporating dry ingredients, mix until just combined to prevent overmixing, which can result in a denser Oatmeal Creme Pie cake.
-
Egg White Safety: Whisk egg whites over simmering water until warm to the touch (about 140°F), ensuring a safe and stable filling for your cake.
-
Storage Tips: Avoid refrigerating the finished cake, as it may harden the filling and dry out the cake. Keep it wrapped at room temperature for best results.
Make Ahead Options
These Oatmeal Creme Pie cake layers are perfect for meal prep enthusiasts! You can prepare the oatmeal cake layers up to 3 days in advance; just cool completely and wrap them tightly in plastic wrap before refrigerating. The fluffy filling can be made up to 24 hours ahead and stored in an airtight container at room temperature to prevent it from hardening. When you’re ready to serve your Oatmeal Creme Pie, simply assemble the chilled layers with the filling and possibly add a decorative swirl on top for a delightful finish. This method not only saves you time on busy days but also ensures your cake is just as delicious when it’s time to indulge!

Storage Tips for Oatmeal Creme Pie
Room Temperature: Store the Oatmeal Creme Pie cake wrapped in plastic or placed in an airtight container at room temperature for up to 3 days to maintain moisture.
Freezer: For longer preservation, you can freeze the individual cake layers separately for up to 2 months. Make sure to wrap each layer tightly in plastic wrap and then foil to prevent freezer burn.

Oatmeal Creme Pie Recipe FAQs
What type of oats should I use for this Oatmeal Creme Pie?
Absolutely! For this recipe, I recommend using quick cooking oats as they absorb the boiling water effectively, providing the perfect texture. If you or your guests have gluten sensitivities, make sure to choose certified gluten-free oats to keep everyone safe while enjoying this delightful treat!
How should I store the Oatmeal Creme Pie cake?
To keep your Oatmeal Creme Pie cake fresh, store it wrapped in plastic or in an airtight container at room temperature for up to 3 days. This method ensures the cake remains moist and enjoyable. If it lasts longer than that (highly unlikely!), you could opt for freezing it!
Can I freeze the Oatmeal Creme Pie layers?
Absolutely! To freeze the cake layers, let them cool completely, then wrap each layer tightly in plastic wrap and place it inside a freezer-safe bag or container. This method prevents freezer burn and keeps them fresh for up to 2 months. When you’re ready to use them, just thaw in the refrigerator overnight.
How can I prevent the filling from hardening?
To avoid the filling hardening, it’s best to store the Oatmeal Creme Pie cake at room temperature rather than refrigerating it. If you happen to have leftovers, simply cover the cake to keep it moist, and consider re-whipping the filling gently if it’s been stored separately. This restores its light, fluffy texture.
Is this Oatmeal Creme Pie suitable for people with allergies?
Great question! This Oatmeal Creme Pie recipe can be modified to accommodate many dietary needs. For those with egg allergies, you can try using aquafaba (chickpea water) in place of egg whites for the filling. However, please consult with family or guests about any specific allergies before serving, as the filling does contain eggs.
Can I substitute ingredients in this recipe?
Certainly! If you want a dairy-free option, you can replace unsalted butter with coconut oil in the cake and use a dairy-free cream for the filling. Additionally, feel free to swap out the shortening for unsalted butter in the filling, which gives it a creamy texture if you prefer that flavor. The more the merrier when it comes to variations to suit your taste!
