Ingredients

This gluten-free strawberry rhubarb crumble uses simple pantry staples and fresh fruit for bold flavor.

For the fruit:

• 2 cups rhubarb, chopped
• 2 cups strawberries, hulled and chopped
• 1/4 cup granulated sugar
• 1 tbsp cornstarch
• 1/2 tsp vanilla extract
• 3/4 tsp almond extract
• Pinch of salt

For the topping:

• 1 1/4 cups certified gluten-free rolled oats
• 3/4 cup oat flour (gluten-free)
• 2/3 cup brown sugar
• 1/2 cup + 1 tbsp melted butter or coconut oil
• 1/4 tsp salt

Instructions

Preparation

Start by preheating the oven to 180°C (350°F). Grease a baking dish to prevent sticking. Next, mix sugar, vanilla, almond extract, cornstarch, and salt in a large bowl. Add strawberries and rhubarb. Stir well so the fruit absorbs the flavor evenly.

Let the mixture sit for 10 minutes. This step allows the fruit to release natural juices. It also helps the filling thicken later during baking.

In a second bowl, combine oats, oat flour, brown sugar, salt, and melted butter or coconut oil. Mix until you get a crumbly texture. The mixture should hold together slightly when pressed.

Spread the fruit mixture into the baking dish. Then evenly distribute the topping across the surface. Place the dish on a baking tray to catch any bubbling juices.

Bake for 40–45 minutes. Watch for a golden top and visible fruit bubbling at the edges. That signals proper caramelization and texture development.

Serving

Let the crumble cool for at least 30 minutes. This step matters because it allows the filling to set. Serve warm for a soft texture or at room temperature for cleaner slices.

You can pair it with:

• Vanilla ice cream
• Greek yogurt
• Coconut cream
