Berry Crumble Bars are bursting with fresh mixed berries and topped with a pecan-studded crumble. These bars are easy to make and perfect to serve at any spring brunch or party.
Preheat oven to 375 degrees F. Grease a 9x13-inch baking pan with butter or nonstick cooking spray. You can also line the pan with foil or parchment before greasing the pan to ensure they do not stick.
In the bowl of a food processor, combine the light brown sugar, granulated sugar, flour, baking powder, cinnamon and salt. Pulse the mixture in the food processor a few times to incorporate the ingredients. Add in the butter and continue to pulse the food processor until the mixture comes together and small clumps form. Add in the egg and pulse again to combine.
If you do not own a food processor, you can use a pastry blender or two forks to cut the butter into the flour mixture. It will take a little more time, but it is totally doable.
Spoon half of the crumble mixture into the prepared pan and use your hands or the bottom of a measuring cup to pat the mixture into an even and compact crust layer.
Add your berries to a large bowl and gently toss them with the lemon juice.
In a small bowl, whisk together the granulated sugar and cornstarch. Sprinkle the cornstarch and sugar mixture over the top of the berries and gently toss to cover the berries with the mixture. Pour berries evenly over the crust.
Crumble the remaining crumble topping over the berries. To make little clumps, simple squeeze the crumble topping in your hand and sprinkle the crumbs to create a topping layer. Sprinkle pecans on top of crumble topping.
Bake in preheated oven for 45 minutes, or until the topping is golden brown. Cool completely before serving.
Serve these berry crumble bars alone, or slightly warmed up with a scoop of vanilla bean ice cream.
