I opted to make half of the recipe and now I wish I'd gone for the whole thing! These are almost like a pie in bar form. The lemon zest in the crust really adds something special and they are so, so good cold from the fridge! If you choose to make the full batch, double the below recipe (do not double the egg or lemon measurements, I kept those the same).

2. In the bowl of a food processor, mix 1/2 cup sugar, flour, and baking powder. Add in salt and lemon zest. Add egg and butter and pulse until dough is a crumbly mixture (can do this all by hand with a pastry cutter or a fork if desired).
3. In a separate bowl, mix 1/4 cup sugar with lemon juice and cornstarch. Pour in blueberries and mix to coat.
4. Press half of the dough mixture into the prepared pan. Pour blueberries over the dough evenly. Top with remaining dough.
