Oatmeal pie crust recipe makes an easy, naturally gluten free pie crust using only 4 affordable ingredients and no rolling or chilling! Ideal for both bake and no bake pie recipes, pie crusts using oatmeal or oat flour makes an effortless alternative to graham cracker or traditional crusts.
Place the oats, melted butter, powdered sugar, cinnamon, and salt in a food processor. Blend until well combined and the oats clump together, about 20-30 seconds.
Press firmly on the bottom and up the sides of a 9-inch pie dish. Tip: To make the crust come all the way up the sides, press evenly on the bottom to work the excess crust up the sides.
For a fully baked pie crust, bake for 18 minutes, or until oats are set. If the crust puffs up during baking, use a measuring cup to flatten gently immediately when it comes out of the oven. Cool completely before filling.
To fill with an unbaked filling, bake for 5 minutes before filling. Bake according to pie instructions, but for best results, bake the pie on the lowest oven rack.

FREQUENTLY ASKED QUESTIONS
What kind of pie filling can be used with this crust? I've tested the recipe with a baked pie, such as pumpkin, and no bake pies, such as gluten free key lime pie, frozen lemon pie or chocolate peanut butter pie. Fortunately, both work very well. See the baking tips below for baked fillings.
How do I adapt this recipe for a baked filling?To fill with an unbaked filling, bake for 5 minutes, fill, and then bake according to pie instructions. A pie shield may be used to protect the exposed crust while it bakes longer.Baked fillings, such as pumpkin and apple, will cause the bottom crust to be a little softer than traditional crusts, but it will still hold up for cutting and serving. For best results, bake the pie on the lowest rack.
Can I make this without a food processor?Yes, simply mix everything together in a bowl and press in the pie plate. However, the crust might fall apart a little more upon cutting because the food processor does a better job of binding the ingredients together.
