These easy crunchy mixed berry crumble bars are a perfect summer snack with a buttery, golden crust and a sweet, tangy berry filling. Ready in under 45 minutes, they are quick, simple, and loved by all ages.
Keep the butter cold to ensure a crumbly, flaky topping. Do not overmix the crumble to maintain texture. Use fresh or frozen berries; if frozen, thaw and drain excess juice to avoid soggy bars. Let bars cool completely before cutting to prevent falling apart. Adjust cornstarch to 3 tablespoons if berries are very juicy. Lemon zest adds brightness and is highly recommended. For gluten-free, substitute flour with gluten-free baking blend. For dairy-free, use solid coconut oil or vegan butter. Add nuts for extra crunch if desired.
