The Gluten-Free Blueberry Crumb Bars are a sweet, tender, and buttery treat that's vegan, allergy-free, and healthy! Made with a shortbread crust, layered with homemade blueberry jam, and topped with a soft buttery crumble. Like a bite of blueberry pie, these streusel-topped dessert bars are delicious served warm with a scoop of vanilla ice cream or straight from the fridge!
