What Are Rasberry Crumble Bars?

A crumble bar is essentially taking a crumble or crisp recipe and turning it into a sliceable bar. Generally a “crisp” has an oaty topping on it, whereas a crumble generally has a topping that is a mix of butter, sugar, and flour. The topping pairs deliciously with baked fruit, like in this Healthy Apple Crisp and Healthy Strawberry Rhubarb Crisp.

Raspberry crumble bars are delicious gluten-free treats that combine a buttery crumbly crust with a fruity and slightly tart raspberry filling. They are perfect for a quick snack, a light dessert, or even a brunch treat alongside your favourite beverage.
