Make these melt-in-your-mouth Lemon Blueberry Shortbread Bars before summer is over! Homemade shortbread is used for both crust and the crumble topping, and the filling is a homemade lemon custard with fresh blueberries on top.
If you don’t have almond extract, you can use more vanilla extract instead.
If you don’t have fresh blueberries, you can use frozen blueberries (add them to the filling frozen otherwise they’ll add too much liquid to the shortbread bars; you may need to add a few extra minutes to the overall bake time). Additionally you can use blueberry jam.
