This homemade strawberry crumble recipe is sweet, buttery, and so easy to make! It's made with oat flour, naturally sweetened with maple syrup, and topped with a crisp, crumbly oatmeal streusel. You can use fresh or frozen strawberries!

Berry crisps and cobblers have always been my go-to summer desserts. I love classics like blackberry cobbler, mixed berry crisp, and peach crisp, but this homemade strawberry crumble might just be my favorite!
It's so easy to make—just mix fresh or frozen strawberries with maple syrup and lemon juice, then top them with a buttery oatmeal crumble. In 10 minutes, it's ready for the oven!
The strawberries get warm and jammy, and the crisp topping turns golden and delicious. Just like my homemade strawberry crumble bars!
Serve it with a scoop of vanilla ice cream, and you've got the perfect summer treat. It also happens to be gluten-free and dairy-free, but you'd never know. I can't wait for you to try it!

The ingredients
Here's what you will need to make this easy strawberry crumble recipe:
- Strawberries – Fresh is best for the best flavor, but frozen works too!
- Coconut Sugar – Optional, but adds a nice sweetness.
- Lemon – Both the juice and zest for a little tang.
- Cornstarch (or Arrowroot/Tapioca Starch) – This helps thicken the filling.
- Rolled Oats – Use old-fashioned oats (gluten-free if needed).
- Oat Flour – Gives the topping that perfect, crisp texture.
- Walnuts – They add crunch, but you can swap them with almonds or pecans, or skip them if you're nut-free.
- Cinnamon – Just a small amount for cozy flavor.
- Maple Syrup – Naturally sweetens the crumble and helps the topping crisp up.
- Coconut Oil – Makes the crumble soft inside and crispy outside. You can use butter or vegan butter instead!
How to make the strawberry crumble:
Homemade strawberry crumble is so easy to make. Preheat your oven, and let's get baking:
If you washed your strawberries, make sure they're dry. Toss the strawberries, coconut sugar, lemon juice, lemon zest, vanilla, and starch in a bowl.
Spoon them into a greased baking or pie dish.
Mix the oats, oat flour, walnuts (if using), coconut sugar, salt, and cinnamon in another bowl. Pour in the maple syrup, melted coconut oil (or butter), and vanilla, then mix with your hands.
Spread the oat mixture evenly over the strawberries.
Bake for 32–42 minutes until the top is golden and the strawberries are bubbly. (I baked mine for about 40 minutes.)
Tip: Let the strawberry crumble cool for 10–15 minutes before digging in! I love serving mine with vanilla ice cream, but I've included other topping ideas you can try below. Enjoy!

Top Tips
- Fresh or Frozen Strawberries: This recipe works with both, making it super flexible depending on what you have!
- No Need to Defrost Frozen Strawberries: If you're using frozen strawberries, don't thaw them. Just coat them in lemon juice and starch, then toss them straight into the pan. Thawing them first can make the texture mushy.
- Make Ahead: You can prep the crumble a day in advance. Just cover it with foil and refrigerate it until you're ready to bake. If you've already baked it, reheat it in the oven for 10-15 minutes before serving.
Equipment
- 2 Large Mixing Bowls
- Spatula or mixing spoon

Substations & Variations

- Crispier Topping: For an extra crispy topping, add a few tablespoons of shredded coconut to the oat mixture.

- Mix Up the Fruit: Feel free to swap the strawberries with blueberries, blackberries, or mixed berries.

Storage & Freezing
Storing: Enjoy the crumble within 3-5 hours of baking for the best taste. Leftovers can be stored in the fridge for up to 3 days in a sealed container or in the original baking dish covered with aluminum foil.
Reheating: Reheat the whole crumble in the oven for 10-15 minutes at 350°F for the best results. If you're heating a single serving, microwave it for 45-60 seconds in 15-second intervals to avoid burning the berries.
Freezing: You can freeze the baked crumble! Store it in a freezer-safe, airtight container for up to 6 months. When ready to enjoy, thaw it overnight in the fridge, or bake it straight from frozen at 350°F until warmed and bubbly.
Frequently Asked Questions
