Summer is all about eating as much fresh fruit as possible. I think we can all agree on that! And when that fresh fruit is about to go bad, it’s all about using that fruit in crumb bars. There really isn’t a much better way to use up your hoard of blueberries than in these blueberry lime crumb bars!
A rich, buttery crust is topped with a sweet blueberry lime filling and more crumb topping. For an extra bit of lime, be sure to add some additional lime zest right before serving. The melt-in-your-mouth shortbread crust combined with the fresh blueberry filling and slightly crunchy topping make these bars irresistible!
A bit of coarse sugar is sprinkled over the top right before baking to give the topping that bit of crunch. I just recently started pairing blueberries with lime, and now that combination has found it’s way into most of my baking. If you haven’t tried the combo yet, these crumbs are the best way to try it out. Summer just calls for easy crumb bars filled with fresh, seasonal fruit!
