This gluten-free and dairy-free Oat Crumble Blackberry Pie is sweetened with just honey and maple syrup. The perfect dessert to satisfy your sweet craving in a healthy way.
This recipe was inspired by Fit Foodie Find’s Lemon Blueberry Crumble Bars. So so so good, as well!
How To Make Almond Oat Crumble
Easy! Just mix almond flour, old-fashioned rolled oats, and a bit of salt with vanilla, a splash of nut milk, maple syrup, and coconut oil. Take a spoon to combine it all and about 2 minutes later you have your crumble.
You use this as a base crust for the pie and also as crumble on top. To use for the base just add to an 8″ springform and press it down firmly with your fingers and the palm of your hands until you evenly cover the bottom.
Prebake the base so it doesn’t become soggy when you add the filling. This is a great gluten-free alternative to a wheat-flour-based pie crust as used in my simple pear tart.
For the blackberry pie crumble layer on top, leave the almond oat crumble the way it was once you first mixed it. Sprinkle it on top of the filling and it will be deliciously crumbly and still somewhat soft because it’s baked less time than the base.
How Do You Make Blackberry Pie Filling From Scratch?
Similar to jam. Just cook the blackberries until they are easy to squish against the wall of the pot. This takes about 15 minutes. Sweeten them with the sweetener of your choice. Honey, Maple Syrup, brown sugar, white sugar or even sugar alcohols work perfectly fine. And if you are a coconut fan, add some desiccated coconut.
The best way to thicken the filling is to add some sort of starch to it. Corn starch, potato starch, or tapioca starch all work well. Make sure you add the starch from the beginning of the cooking process so it dissolves well and doesn’t clump.
This obviously works with any berry, not just blackberries. Strawberries, blueberries, raspberries…. even cherries work fantastic with this from-scratch filling.
How To Store the Pie and How Long Does It Last?
The pie is best stored in an airtight container in the refrigerator and lasts for 3-5 days in there.
This blackberry pie freezes really well though, so if you won’t be able to finish it within 5 days, store in a freezer-safe container for up to 3 months. To defrost, simply add to the fridge 12 hours prior to consumption.

Kristina says
A complete disaster.
Carrie says
Tried with cherries and added 3.5 cups of cherries instead of 3 cups. There’s some effort in pitting all those, but it was worth it. I can’t stop making these (while cherries are in season) and freezing them for later. Thanks for the recipe!

Any suggested substitutions for coconut oil? Watching my saturated fat intake.
Lorena Grater says
Unfortunately, the only alternative would be butter which has the same amount of fat. You need a fat that is liquid when warm and solid when cold for the pie to hold its shape.
LAUREN says
Would Blueberries work instead of Blackberries
Lorena Grater says
absolutely!
Jojo says
I hi, can I use frozen berries?
Lorena Grater says
I’m afraid that will make the dough very mushy because of the high water content but maybe worth a try?
Caro says
It’s okay! Don’t think it is worth the 449 calories! :D
Doris Valentine says
I never liked coconut. Would it affect the recipe if I didn’t use it? Or substitute something else?
Laurie says
Would it work to replace the coconut oil with unsweetened applesauce? I can’t have oil.
LouAnn says
I cannot have any oils.
Any sub for that coconut oil?
