I ate these gluten-free blueberry crumble bars for breakfast, lunch, and dinner for a week straight. It was one of those recipes that shouldn’t have been as good as it was. So reluctantly, I thought I’d share! Plus, it’s gluten-free and refined sugar-free for those wanting to bake their blueberry crumble bars and devour them too. Forget those hyphenated scaries and let the real star of this gluten-free recipe show off… butter.

Butter is beautiful. It plays such a distinct role in many forms of cooking, especially baking. Butter makes this the crispiest and most flavorful crust that pairs perfectly with the sweet tartness of the baked blueberries. Each bite is buttery, salty, sweet, and crumbly goodness.
