1 teaspoon lemon juice
1 teaspoon cornstarch (optional, for thickening)
1/2 teaspoon vanilla extract (optional)

For the crumble topping:

1/2 cup old-fashioned rolled oats
2 tablespoons almond flour (or whole wheat flour for a different option)

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the oven:
Preheat your oven to 350°F (175°C) and grease a small baking dish (about 8×8 inches) with cooking spray or lightly coat it with coconut oil.
Prepare the blueberry filling:
In a medium bowl, toss the blueberries with honey or maple syrup (if using), lemon juice, cornstarch (if using), and vanilla extract. Stir until the blueberries are evenly coated. Transfer the mixture to the prepared baking dish and set aside.
Prepare the crumble topping:
In a separate bowl, combine the rolled oats, almond flour, chopped almonds or walnuts (if using), melted coconut oil or butter, honey or maple syrup (or sugar substitute), cinnamon, and a pinch of salt. Stir until the ingredients are fully mixed, and the mixture resembles a crumbly texture.
Assemble the crumble:
Evenly spread the crumble topping over the blueberry filling in the baking dish, covering the berries completely.
Bake the crumble:
Bake in the preheated oven for 25-30 minutes, or until the filling is bubbling and the topping is golden brown. If the topping starts to brown too quickly, cover it with foil and continue baking until the filling is set and the topping is crisp.
Cool and serve:
Let the crumble cool for 10 minutes before serving. It’s perfect on its own or with a scoop of low-fat vanilla yogurt or a drizzle of almond butter for extra flavor.

FAQs

1. Can I use frozen blueberries?

Yes, frozen blueberries work just fine in this recipe. There’s no need to thaw them before using. Just keep in mind that frozen fruit may release more liquid during baking, so using cornstarch helps thicken the filling.

2. Can I make this crumble ahead of time?

Yes, you can prepare the filling and topping ahead of time and store them separately in the refrigerator. When you’re ready to bake, just assemble them and bake as directed.

3. Can I make this crumble without the nuts?

Yes, you can skip the nuts if you prefer or have a nut allergy. The crumble will still be delicious with just the oats and almond flour for texture.

4. Can I use a different type of flour?

Yes, you can use regular flour, coconut flour, or oat flour as a substitute for almond flour. Keep in mind that the texture may vary slightly depending on the type of flour used.

5. Can I add more sweetness to the filling?

Yes, feel free to add more honey or maple syrup to the filling if you prefer a sweeter taste. Adjust the sweetness to your preference by tasting the filling before baking.

6. Can I use a different fruit in this crumble?

Yes, you can swap the blueberries for other fruits like apples, peaches, or pears. You can also combine different fruits for a mixed-fruit crumble.

7. Can I make this crumble gluten-free?

Yes, this recipe can easily be made gluten-free by using gluten-free oats and almond flour in the topping. Just make sure all your ingredients are certified gluten-free.

8. Can I use a different sweetener to reduce calories?

Yes, you can use a sugar substitute like stevia, monk fruit sweetener, or erythritol to cut down on the calories and sugar content.

9. How do I know when the crumble is done?

The crumble is done when the topping is golden brown and the filling is bubbling around the edges. You can test the filling by inserting a fork into the center—if it’s hot and bubbly, it’s ready.

10. How can I make this crumble more crunchy?

For a crunchier topping, you can add more nuts or even some seeds like sunflower or pumpkin seeds. You can also increase the amount of oats for extra texture.
