Ingredients
- 1/2 cup white sugar: This sugar adds sweetness and enhances the flavor of the blueberries.
- 1/4 cup brown sugar: Providing moisture and a slight caramel flavor, brown sugar complements the depth of the dessert.
- 1 cup all-purpose flour: This forms the base for both the crumble and crust, creating the ideal texture.
- 3/4 cup quick oats: These add a chewy texture and nuttiness, integrating beautifully into the crumble topping.
- 1 egg yolk (room temperature): The yolk helps bind the ingredients together for a more cohesive texture.
- 1/2 cup unsalted butter (melted): This creates richness and moisture in the crumble while aiding in browning.
- 1/2 cup white sugar (for filling): Used to sweeten the blueberry mixture, balancing the tartness of the fruit.
- 3 tbsp lemon juice: This adds brightness and enhances the blueberry flavor with a zing.
- 2 cups frozen or fresh blueberries: The star of the recipe, blueberries provide juicy bursts of flavor with each bite.

- Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
- In a large mixing bowl, combine the brown sugar, white sugar, all-purpose flour, and quick oats. Stir until they are thoroughly mixed.
- Add the egg yolk and melted butter to the mixture, mixing until it becomes crumbly but holds together when pressed.
