Very berry shortbread bars are so delicious. A tart mixture of raspberries, blueberries, and blackberries topped with a crunchy streusel and white icing. The shortbread crust is so soft and buttery.
This recipe was decidedly named by Baby G, the most creative girl I know. We were looking for a way to use a bag of mixed berries we had in the freezer and this is it!
The mix of berries is a powerhouse of superfood berries. Each type of berry contains so many beneficial nutrients. The mix of berries provides a dose of fiber, vitamins, and antioxidants.
These very berry shortbread bars are shelf stable in an airtight container for up to 5 days.
