Instructions

Preheat the oven to 375 F. Prep a 9x9x2 inch pan by buttering, spraying with cooking spray or lining with parchment paper.
In a medium mixing bowl, whisk or stir together the dry ingredients for the crumb mixture. Cut in the butter using a pastry cutter, two knives or your fingers. The mixture should resemble a fine crumb. Stir in the egg and vanilla until well mixed. Press 1/2 – 2/3 of the mixture into the bottom of the pan.
In a smaller mixing bowl, mix together the filling ingredients. Spoon the fruity filling over the crust in the pan, avoiding the juices at the bottom of the bowl. (Use them for another purpose.) Sprinkle the remaining crumb mixture on top of the fruit.
Bake at375 F. for 35 – 45 minutes or until the topping is lightly browned. Cool completely, then cut into bars and enjoy!

Notes

Instead of hand mixing, you can use a food processor to prepare the crumb mixture.

Store these bars in the fridge.
