- Unbaked Pie Crust: Frozen shells saves time and provides a flaky crust without the hassle of making dough from scratch. Frozen regular pie crusts is recommended. Deep dish can be used if it’s the only thing available, but it’s NOT ideal as it’s tougher to serve and slice with a pretty slice.
Tools You’ll Need

Variations
Here are some of our favorite flavor variations for this dessert:
- Oatmeal Raisin Cookie: Fold 1/2 cup raisins into the filling before pouring in the crusts.
- Kentucky Derby Flavor: After pouring the filling into each crust, add 1/4-1/3 cup semi-sweet or milk chocolate chips to the top of each pie to liken the flavors of a the traditional pie served at the Kentucky Derby.
- Reese’s Cup: After pouring the filling into each crust, add 1/4 cup each milk chocolate chips and peanut butter chips to the top of each pie to liken the flavors of a Reese’s Cup.
- Peanut Butter Oatmeal: After pouring the filling into each crust, add 1/4-1/3 cup peanut butter chips to the top of each filling.
Expert Tips
- Swap out the Nuts. If you’re not a fan of pecans, any chopped nuts like walnuts or almonds would work well.
- Omit the Coconut. You can omit the coconut if desired; just increase the oats slightly to maintain the volume of the filling.
- Use Maple Syrup rather than Pancake Syrup. Maple syrup can be a delightful alternative to pancake or corn syrup for added depth of flavor. However, make sure it has the same viscosity. Thinner maple syrups will yield thinner filling.
- Add Cinnamon. Some old-fashioned oatmeal pie recipes call for a hint of cinnamon. You can add 1/2 teaspoon ground cinnamon if desired.
- How to make Unsalted Butter into Salted. Unsalted butter can also be used. Simply add a 1/4 teaspoon salt.
- Other Crust Options. Frozen regular pie crusts is recommended. Deep dish can be used as well if it’s the only thing available, but it’s NOT ideal as it’s tougher to serve and slice with a pretty slice.
- Instead of a store-bought pie crust, you can opt to use your favorite homemade pie crust dough. Depending on its thickness, you might need to par-bake to ensure doneness a the end of bake time.
Storage
To store leftover oatmeal pie, cover it tightly with plastic wrap, aluminum foil or store in an airtight container in the refrigerator for up to 4 days. It’s a great pie to make ahead of time too for entertaining ease.
You can also freeze the pie for longer preservation. To do this, wrap it securely in plastic wrap and then in aluminum foil before placing it in the freezer. It can last up to 2 months. Thaw in the refrigerator overnight before serving. It’s best to serve at room temperature.

looks yummy and easy easy to make
Aww!🥹You’re so sweet! Thank you SO much!!!🥰
How do I cut the ingredients to make just one pie?
Cut everything in a 1/3 and that will work 🙂
Hi Laura – this pie looks fantastic and I would love to try making it. I’m confused on the amount of butter to use. It appears you use two sticks of butter in the video, but the recipe calls for 1/2 cup which would be only one stick of butter. Can you please clarify? Thanks so much!
Hi Susan! 🙂 Those were half sticks that add up to be 1/2 cup. That’s one thing I always have to correct on my Mamaw’s recipes. She’ll say “add a stick of butter” and our store sells sticks that are 4 tbsp and sticks that are 8 tbsp. So, yes, 1/2 cup/8 tbsp is the right amount. I hope you love them!
Hi. If I omit the coconut, what measurement should I increase the oats to? Thanks so much!!!
The recipe calls for 1 1/2 cups shredded sweetened coconut, so this is a guess…but I would start with another 3/4 cup oats. If the mixture appears too thing (look at the video to determine this) then you could add more.
I made the Oatmeal Pie as a thank you to our very kind neighbors!
