Summer Berry Crumble
Juicy mixed berries under a golden, buttery oat crumble topping
By RecipesQueen Kitchen • June 10, 2026
A summer berry crumble is the easiest, most satisfying dessert — juicy, bubbling berries under a golden, crunchy blanket of buttery oats and brown sugar.
Use any combination of berries you love — blueberries, blackberries, raspberries, strawberries. Frozen berries work perfectly.
The crumble topping should be in uneven chunks, not uniform — the irregular pieces create a mix of crunchy and chewy textures.

- 1 tbsp cornstarch
- 1 cup old-fashioned oats

- 1/3 cup cold butter, cubed
- 1/2 tsp cinnamon
