Oatmeal pie crust is easy to prepare and makes a great substitute for graham cracker crust. All you need are 6 ingredients and 15 minutes of prep time, then simply press it into a pie plate and bake! Ideal for no-bake pie fillings like key lime, chocolate, cheesecake, and cream pies.

This oat pie crust recipe is gluten-free, vegan, and nut-free.

Why You'll Love It

This homemade oatmeal pie crust tastes amazing - like oatmeal cookies! - and the crisp-yet-chewy texture is the perfect contrast to creamy pie fillings.

It's lightly sweetened, with a hint of cinnamon and vanilla, and bakes up in just 15 minutes. No rolling pin or pre-chilling involved!

For years, this vegan gluten-free pie crust has been my go-to. It's not only delicious and ridiculously easy to make, but since it's made from almond flour and contains no extracted oils, it's also healthier than your average pie crust.

In fact, that pie crust has been so popular with my readers I also created a nut-free version: sunflower seed crust.

But recently I wanted to test a new recipe idea for a no-bake cheesecake. A graham cracker crust would have been perfect, but ideally I wanted to keep the dessert both vegan AND gluten-free.

Since vegan gluten-free graham crackers are pretty much impossible to find, I decided a pie crust made with oats would be perfect!

Ingredients

A labeled photo of the ingredients needed to make pie crust with oats.
  • rolled oats - look for regular, old fashioned rolled oats. I suspect quick oats will also work, but I haven't tested that yet.
  • vegan butter - I used Earth Balance unsalted sticks. If using salted butter, you can omit the salt. If you're one of my regular oil-free readers, I'm happy to report that applesauce can be used instead, though it does affect the texture of the crust. Or try one of these: healthy pie crust, seed pie crust, or nut and date crust.
  • maple syrup - or agave; this adds just a touch of stickiness and moisture, plus great flavor!
  • sugar - regular granulated sugar sweetens the crust, adds crispness, and helps it brown.
  • cinnamon - optional but recommended; since oats don't taste like much on their own, just a touch of cinnamon really takes the flavor up a notch. Bonus: cinnamon tastes lovely with pretty much any pie filling, like chocolate, vanilla, cheesecake, berries, apples, pears, peaches, etc.

See the recipe card below for quantities and complete instructions.

How to Make Oatmeal Pie Crust

Pulsing oats in a food processor to turn into pie crust.

Add the oats and other dry ingredients to a large food processor. Let it run for about 10 seconds, then pulse until the oats are mostly broken down. A few larger pieces are fine.

Adding melted butter to the dry ingredients in the food processor.

Add the melted butter, vanilla, and syrup, then pulse until fully combined.

Spoon the oat mixture into a glass pie plate, evenly spreading it around the dish.

Using the bottom of a measuring cup to press the oat pie crust into the dish.

Starting in the center and working toward the edges, firmly press the crust mixture into the pie dish using your hands or the flat bottom of a measuring cup or glass.

Bake in a preheated 350 degree (177 C) oven for 16 to 18 minutes or until lightly golden.

Tip: During the last few minutes of baking the crust may begin to puff up slightly. After removing the pie crust from the oven, use the measuring cup or a large spoon to gently press it down.

Substitutions

  • maple syrup - agave nectar is an easy swap, or use an additional tablespoon of sugar plus 1 tablespoon of water or non-dairy milk.
  • sugar - regular granulated sugar is the only sweetener I've tested so far. Light brown sugar or coconut sugar should also be fine. I'm not sure whether low-calorie, alternative sweeteners would work.
  • vegan butter - it's possible other fats could work, such as coconut oil, vegetable shortening, but vegan butter is the only one I've tested so far.
    *If you're one of my regular oil-free readers, I've also successfully made the recipe with ½ cup applesauce replacing the vegan butter. Obviously, this changes the texture to be more chewy than crisp, but it's actually quite delicious!
    I also have three other crust options that are made without extracted oils: healthy pie crust, seed pie crust, and nut and date crust.
  • oats - since this is an oatmeal pie crust, obviously oats are an important ingredient. I also tested it once with oat flour, but found it much less forgiving. I love oat flour for baking, but for pie crust, it would have needed other flours and ingredients to get the proper texture.

Fat-Free Pie Crust Variation

Recently while finalizing this tofu cheesecake pie recipe, I tested the oatmeal crust with applesauce instead of vegan butter. It worked surprisingly well!

With applesauce the texture is more chewy than crisp, but that's to be expected. It held to gether perfectly, didn't stick to the pie plate (even without oiling the dish), and tasted great.

So if you're watching your fat intake, or baking a treat for someone who is, this is a great option. Here's how to do it:

  • replace the vegan butter with ½ cup applesauce
  • omit the maple syrup
  • and increase the bake time to 20 minutes

Frequently Asked Questions

Can I use oat flour instead of oats?

A straight swap doesn't work in this recipe because oat flour absorbs more moisture than the pulsed/chopped oats do. If all you have is oat flour, it's probably best to search online for an oat flour pie crust.

Do I have to use a food processor?

Not necessarily. You could pulse the oats in a blender, then combine with the other ingredients in a bowl. Just be careful not to blend the oats too long - we don't want fine oat flour. It's best when there's some variety in the texture.

Does it work for baked pies?

This oatmeal crust isn't the best option for baked pies, especially ones with longer bake times like pumpkin, because the edges will burn. A pie shield might help, but this vegan gluten-free pie crust is a better option.

Can I make it in advance?

Absolutely! After removing the pie crust from the oven, cool completely then cover with plastic wrap and refrigerate for up to 3 days before using. It also holds up well for a couple of days once filled. Keep in mind, any type of filling that contain an excessive amount of liquid will affect the texture.

Top Tip

Since the pie crust contains no flour or gluten, it tends to be a tad crumbly, sort of like graham cracker crust. Just make sure the oats are well processed and that you firmly press the mixture into the pie dish, and it will hold together beautifully.

Pie Fillings

Pair this oatmeal pie crust with no-bake pie fillings like:

  • A slice of vegan key lime pie topped with aquafaba whipped cream with the rest of the pie nearby.
    Vegan Key Lime Pie
  • a slice of vegan chocolate pie on a dessert plate with a bite taken out.
    Vegan Chocolate Pie
  • whole cheesecake resting on a white cake stand

Equipment

  • food processor
  • 9-inch pie dish (1.75 in. deep)

Ingredients

  • 2 cups old fashioned rolled oats - certified GF if needed; tap Metric above for weight
  • 3 tablespoons sugar
  • ½ teaspoon cinnamon
  • ¼ teaspoon fine sea salt, optional - omit if using salted butter
  • 6 tablespoons vegan butter, melted - see Notes for fat-free option
  • 1 tablespoon maple syrup or agave
  • ½ teaspoon vanilla extract

Instructions
 

  • Preheat oven to 350°F (177°C).
  • In the bowl of a large food processor, combine the oats, sugar, cinnamon, and salt, if using. Process for about 10 seconds, then pulse until the oats are mostly broken down but still coarse.
  • Add the melted butter, syrup, and vanilla. Process again until everything is well combined. The mixture should be moist and easily clump together.
  • Spoon the oat mixture into a 9-inch glass or ceramic pie plate, evenly distributing it around the dish. Starting in the center and working out toward the sides, firmly press the mixture into the bottom and sides. I like to use the flat bottom of a glass or measuring cup. Use your hands to make sure the sides are pressed in firmly.
  • Bake for 16 to 18 minutes or until set and lightly golden. During the last few minutes in the oven, the crust may puff up slightly. After removing from the oven, use the measuring cup (or a large spoon) to gently press it down.
  • Cool completely, then add your favorite no-bake filling. See Notes for tips.

Notes

Don’t sub dairy butter: Note that vegan butter has a higher water content than regular butter, in addition to other differences in the fats. I don't use dairy and have only tested the recipe with vegan butter. According to comments left by others, a straight swap with dairy butter does NOT work in this recipe and creates a crust that is too hard. 
Fat-free/oil-free option: If you follow a low-fat diet, you'll be glad to know this crust works beautifully with applesauce instead of vegan butter. Note that the texture ends up softer/chewier, but it holds together perfectly and tastes great! To do it, use ½ cup applesauce, omit the maple syrup, and increase bake time to 20 minutes.
Don't have a food processor? Pulse the oats in a blender, then combine with the other ingredients in a large bowl. Be careful not to blend the oats too long (we don't want fine oat flour). It's best when there's variety in the texture.
Can I use it for baked pies? This isn't the best crust for baked pies, especially ones with longer bake times like pumpkin, because this crust bakes up more quickly. A pie shield may help, but this vegan gluten-free pie crust is a better option.
Use this crust with no-bake fillings like chocolate, key lime, vegan cheesecake, banana cream, etc. It's a great sub for graham cracker crusts.
Storing/Make Ahead: Cool completely then cover with plastic wrap and refrigerate for up to 3 days before filling. It also holds up well for a couple of days once filled. Keep in mind, any type of filling that contain a lot of moisture will affect the texture.

    I'm trying this for a no bake cheesecake, 2 questions..
    Can I use my springform pan and I'm also using dairy butter, I read the comments about dairy butter not working well in this recipe, I'm thinking I could just add a little bit of milk to make sure theres enough moisture, what do you think

    Reply
    • Lori Rasmussen says

      April 13, 2025 at 7:07 pm

      As long as the springform pan is similar size, that should be fine. Note that metal pans conduct heat faster/differently so I would check it early. You may need to reduce the bake time by a minute or two. Adding some moisture is a good idea, and reduce the butter by about 1/2 Tbsp (that's my best guess). Hope you have success!

      Hi Susan - Though I haven't tried it, I think a straight swap might make the crust too crisp. You could try 4 Tbsp coconut oil plus 1-2 Tbsp water or non-dairy milk. Hopefully that will be enough moisture to soften the oats just a little bit and replicate the water content of vegan butter.

    My crust just popped out when I turned it over and onto a cooling rack, zero effort needed. I used molasses instead of maple syrup and I found it a tad too sweet. Well, I haven 't tasted it yet, I have black chocolate cherry filling on top. Can't wait! Thank you for the recipe.

    I made a similar recipe using brown sugar instead of granulated sugar and cut the butter into it rather than melting the butter. I found that the crust stuck to the pan and was very difficult to remove. Does this recipe yield the same result? And if so, what do you do to prevent the sticking? I absolutely love the flavor and texture of this crust with cream pies and would like to use it to prepare some pies for a local bake sale.

      Hi Debbie - I’ve never had trouble with it sticking to my glass pie plate but if you were to use a different type of pie pan you may want to lightly butter it first. Metal pans conduct heat faster than glass so cook time may be reduced. Also be sure to use vegan butter as described. Hope that helps!

      Hi Kathryn - That depends on the filling/recipe. As mentioned, this crust tends to be better for no-bake desserts. But I'm sure you could also find a way to make it work with some combination of partially cooking the blueberries on the stove and par-baking the crust, then finishing it in the oven.

    Made this crust exactly as stated for my strawberry tarte. It was soooo delicious! Disappeared in seconds and eveyone commented on how nice the crust was. Came out just like a Graham cracker crust, but even tastier in my opinion.
    Little tip, I used my stick blender and it was super easy to make the oat flour.

      Hi Caro,
      I really like both so I'd say it depends on the filling. For no-bake fillings you would typically pair with a graham cracker crust, I would probably use this one. But for baked pies or fillings that have a lot of moisture, like pumpkin, I would use the almond flour crust. 🙂

      Hi Emily,
      Yes, it should work well, but unfortunately I haven’t tried it yet. Since oil doesn’t have the water content of vegan butter, you might want to reduce it to 1/3 cup and add 1 or 2 tablespoons of milk. If you give it a try let us know! I’ll be sure to update the recipe as soon as I have a chance to test it.

          Hi Mike - Vegan butter contains more moisture/water, which affects the texture of the oats. I'll be sure to add a note about that to the recipe.
