This tasty mixed berry crumble is incredibly easy to make and absolutely heavenly topped with whipped cream or vanilla ice cream. It involves few ingredients, it's not too sweet and it's perfect for the spring and summer. I absolutely love desserts that give you a flavor, temperature, or texture contrast and this provides all three as we have the warm tangy berry base topped with the buttery, sweet streusel topping served with cold whipped cream or ice cream. Delish! This dish is perfect if you're looking for a dessert to impress your loved ones without spending all your time in the kitchen. It comes together so quickly and easily.
