Blueberry Coffee Cake

The lemon flavor is really nice, this recipe has a few steps involved but it's not hard. I used frozen huckleberries instead of blueberries. Will make it again for sure.

Baked in greased, square glass pan (no parchment paper). Turned out nice. Very tasty. I did not zest a lemon but the lemon juice contrasted nice with blueberries. Might use a little less crumb topping. Used fresh blueberries.
