Juicy blackberries and tangy rhubarb are a match made in heaven together in this summery crumble that's piled high with a buttery almond streusel topping.---Don't forget the whipped cream on top!
Preheat oven to 350F. In a medium bowl, combine blackberries, rhubarb, sugar, and cornstarch. Spread evenly in the bottom of a greased square 8x8 baking pan.
In a separate medium bowl, combine all topping ingredients until crumbly. Sprinkle evenly over fruit filling.
Bake cobbler at 350F 30-35 minutes or until filling is bubbly and topping is golden. Let cool 10 minutes, then serve warm with whipped cream. Enjoy!
