If you are looking for a tasty and satisfying heirloom dessert, Grandma’s oatmeal pie with coconut is just the thing. Grandma spent years perfecting the recipe so you don’t have to. Give it a try and enjoy a bite of gooey pie that is reminiscent of pecan pie without the nuts.

If you have not had an oatmeal pie, you have to give it a try. Some people make it as a more affordable mock pecan pie.
But we think it is good enough to make as its own thing. It is perfect for pie holidays, like Thanksgiving, but is wonderful for any occasion that calls for a cozy dessert.
A family friend’s grandma tinkered with it until it was absolutely perfect. And you know grandmas know what they are doing in the kitchen.
The History of This Recipe
This recipe has been handed down through the generations. That only happens with winners.
Our friend, Lynn, got this recipe from her grandmother. Her grandmother had a way of changing original recipes to make them her own.
She is not sure where the original recipe came from. Remember, this was before we had food blogs and Pinterest and things. Lynn said that her grandmother was a wonderful cook and baker.


She believed very strongly in the quality of her dishes. She believed her recipes were the best and would stand up for them.
I’d love to see her in a baking competition. It sounds like she is a woman who would hold her own.
Why You’ll Love This Pie
It is loaded with oatmeal and coconut, but even coconut haters love it. It is not a prominent flavor, so you have to try it even if coconut isn’t your favorite.
The filling is super easy to make. Just mix everything together in a big bowl and pour it into the crusts.

There are no fussy steps, no prebaking of the pie crust, and no fiddly meringue. Just mix, pour, bake, cool, enjoy.


Once the pie is baked you get the perfect mix of gooey filling and little bit of crunch on the top. It is caramelly and delicious.
The pie is great served at room temperature. Or try it served warm with a scoop of vanilla ice cream.
Carlee’s Tips and Tricks
Make sure to cool the pie before you cut it. If you cut it while it is still hot, you will have a mess on your hands.
It is better to warm up a slice of pie in the microwave for a few seconds than to cut it too early. While the wait it hard, it is worth letting the filling set before you serve it.


This pie is delicious in a traditional crust like MiMi’s extra flaky pie crust of my great-grandma’s tender lard pie crust. For something different, try baking it in a chocolate pie crust for even more flavor.

Grandma’s Oatmeal Pie
Ingredients
- 1 prepared pie crust
- 2 eggs
- ¾ cups light corn syrup
- ½ cup milk
- ¼ cup butter melted
- 1 Tablespoon vanilla extract
- 1 pinch salt
- ¼ cup all-purpose flour
- 1 cup flaked coconut
- ¾ cups old fashioned oatmeal
Instructions
- Preheat oven to 350°F
- Mix together the 2 eggs, ¾ cups light corn syrup, ½ cup milk, ¼ cup butter, 1 Tablespoon vanilla extract, 1 pinch salt, ¼ cup all-purpose flour, 1 cup flaked coconut, and ¾ cups old fashioned oatmeal. Pour into prepared 9 inch deep dish pie crust
- Bake at 350°F for about an hour
- Allow to cool before slicing
Notes
- The original recipe made two pies. I have reduced it so you can just make one. However, you can easily double the recipe for two pies. (There is a handy button in this recipe card for just that purpose!)
- If you would like to freeze the extra pie, wrap it well in plastic wrap and place in the freezer for up to 3 months. Defrost in the refrigerator overnight before serving.
