Apple Custard Pie with Oatmeal Crust

This lightly sweet dessert is a triple threat of oaty goodness, featuring oatmeal, oat flour, and oat milk. The recipe will also work with all-purpose flour and regular milk. A dusting of cinnamon sugar when the pie comes out of the oven gives it a sweet sparkle and crunch.


Ingredient Set Name: 



Ingredient Line: 
1 cup old-fashioned oats
Ingredient Line: 
½ cup oat flour
Ingredient Line: 
¼ cup light or dark brown sugar
Ingredient Line: 
¼ tsp. salt
Ingredient Line: 
¼ tsp. ground cinnamon
Ingredient Line: 
¼ cup (4 Tbs.) vegan margarine, melted

Ingredient Set Name: 



Ingredient Line: 
2 eggs
Ingredient Line: 
¼ cup plus 2 Tbs. sugar, divided
Ingredient Line: 
½ tsp. vanilla extract
Ingredient Line: 
¾ cup oat milk
Ingredient Line: 
3 small apples, peeled, cored, and cut into 8 wedges each
Ingredient Line: 
⅛ tsp. ground cinnamon


1. Preheat oven to 350°F. Coat 8-inch pie pan with cooking spray.

To make Crust:

2. Stir together oats, oat flour, brown sugar, salt, and cinnamon in large bowl. Stir in margarine and 1/4 cup water until crumbly dough forms. Press dough into bottom and sides of prepared pie pan, moistening fingers with cold water, if necessary, to prevent sticking. Place pan on baking sheet, and bake 15 minutes, or until crust is light brown and bottom looks dry.

To make Filling:

3. Whisk together eggs, 1/4 cup sugar, and vanilla in large bowl. Whisk in oat milk until smooth.

4. Arrange apple wedges on bottom of prebaked Crust. Pour Filling into Crust, and return to oven. Bake 30 to 40 minutes, or until Filling is set.

5. Stir together remaining 2 Tbs. sugar and cinnamon. Sprinkle cinnamon sugar over hot pie. Cool on wire rack.

Help! What is oat milk?

You can find oat milk (which is a non-dairy milk) where the soy milk or you can find recipes online. Here is one: and another: Good luck :)

So simple so good! I used almond instead of oat milk and sprinkled some sliced almonds on top.

Can coconut milk be substituted for oat milk?

This recipe is totally awesome!! I love it because the crust is very simple and without wheat and the whole pie is also easy, simple and delicious! Everyone loves it! You would never know there isn't milk in the custard!
