Key Ingredients and Substitutions

  • Rolled Oats: One Degree Organics Gluten-Free Sprouted Rolled Oats are always my go to oats of choice. Using a rolled variety is best for the crumble texture we are aiming for.
  • Flour: You can use a variety of different flours for this recipe like all-purpose flour or gluten-free flours. To keep it gluten-free use almond flour or oat flour.
  • Walnuts: I love adding these omega-3-rich nuts to the crumble as they give it a nice buttery taste. You can omit them or replace them with pecans if that is what you have on hand.
  • Maple Syrup: You can also use agave syrup.
  • Nut Butter: For a more neutral taste, I used almond butter, but I’ve tested this with peanut butter as well and it came out perfect.
  • Almond Extract: This gives the crumble an almost cookie-like taste, which I absolutely adore. You can omit or swap for some vanilla extract.
  • Strawberries: Use fresh or frozen berries for this and even mix it up with a medley of different fruit if desired.
  • Cornstarch: Helps to thicken the filling, but you can also swap for arrowroot starch or flour if preferred.
  • Lemon: Helps to maintain the color of the strawberries as they bake. I also like to zest some of the lemon to add to the filling for more fresh flavor.

Choosing the Right Oats

You know I love oats. Since I use them everyday between breakfast and snacks, it’s really important for me to know more about my oats. So transparency is key. I love that One Degree Organics lives up to their name, you’re only ever one degree of separation between you and where your ingredient is grown.

One Degree Organics Sprouted Rolled Oats are gluten-free, organic and glyphosate-free, making them easier for everyone to enjoy. And they are grown using veganic farming practices, which I love to support. They truly care about the quality of their ingredients and the health of people and the planet. So when I say this is a feel good treat, I truly mean it.

How to Make Vegan Strawberry Crumble

Start with the strawberry filling. Quarter your strawberries and place in a 8-in x 8-in ceramic pan. Top with cornstarch, brown sugar, lemon zest and lemon juice and then toss together to coat.

In a separate bowl, add your oats, flour, nuts, sugar, almond butter and almond extract. ingredients for the crumble and mix to combine making sure your dry and liquid ingredients are fully combined and crumbly in texture.

Top your strawberries with the crumble and bake in the oven. Once cooked, remove from the oven and allow to set for about 15-20 minutes before serving.

Expert Tips

  • If you do not have a gluten allergy, you can replace the gluten-free flour suggestions for regular all-purpose flour.
  • Use rolled oats for the crumble. I would not recommend using quick oats as they are small and softer, which will make it harder for them to crisp up in the oven.
  • Change up the fruit. Combine the strawberries with other berries or choose a different berry or fruit entirely.
  • Make this into a single serving treat. Just fill up a small ramekin with your berries and top with a 1/4 of the crumble recipe.
  • Adjust the sugar based on preference. Use less if your fruit is very sweet, but feel free to add more if your strawberries are especially tart.
  • Make into individual single serve treats. Just divide the strawberries and crumble between 4 ramekins and bake as instructed.

Frequently Asked Questions

How long will this keep?

Once your strawberry crisp cools, cover tightly with wrap or store in an airtight container and place in the fridge for up to 4 days.

Can you make this strawberry crumble with frozen fruit?

Yes! No need to thaw. They can be replaced 1:1 in the recipe with no other modifications needed.

Are sprouted oats healthier than regular oats?

Sprouting grains help to unlock more nutrients within the grain by reducing nutrient inhibitors. So nutrients like protein, fiber, antioxidants and minerals become more available and easier to absorb when digested.

What do you serve a fruit crumble with?

While this sweet summer treat is perfect as is, it’s even better with some dairy-free whipped cream, ice cream, and even more fresh sliced strawberries on top.
