  • Diet: Gluten Free


Made with fresh produce, this Vegan Berry Crumble with Oats is an easy gluten free recipe for summer. Top it with a scoop of non-dairy vanilla ice cream for a dessert everyone will love! 


Units Scale
  • 34 cups of berries of choice – blueberries, raspberries, and/or blackberries.
  • 1 cup (about 4 stalks) diced rhubarb
  • 2 Tablespoons raw sugar or maple syrup
  • 1/31/2 cup (around 70 grams) gluten free oat flour
  • 1/4 cup coconut sugar or brown sugar
  • 1 1/2 cups gluten free rolled oats
  • 1 teaspoon cinnamon
  • 1/4 teaspoon salt
  • 6 Tablespoons solidified soy free vegan butter or refined coconut oil, diced


  1. Preheat the oven to 375° F. 
  2. Heat a large skillet on medium-low heat. Cook rhubarb with 2 teaspoons of sugar or maple syrup for 6-8 minutes or until it softens. 
  3. In a large bowl, combine the flour, sugar, oats, cinnamon, and salt. Add the butter (or solidified oil), and mix with two hands until a crumble texture is formed. Set aside.
  4. Layer the rhubarb, berries, and crumble topping mixture into a cast iron pan or casserole dish. 


Extra Toppings and Tips: Add desired amount of non-dairy ice cream, coconut whip, or yogurt on top. Tip – Double the batch or save extra of the sweetened cooked rhubarb, then spoon it on to top with whipped cream or ice cream. 

Texture Note – Because we added oats  to the crumble topping, the crumble might look similar to a crisp. Half crisp, have crumble.
