    I love that this recipe is made with simple baking ingredients that you probably already have on hand. (My favorite kind of recipes.) Nobody needs to run to the store now just to buy hemp milk or something...

    I also love the fact that it's in season now and the blueberries just literally pop in your mouth.

    How to make buttery blueberry crumble bars:

    The crust and crumble on top are made out of the same things. You simply leave over ¼ of it and sprinkle on top after you put the filling in.

    Start by mixing together the sugar, brown sugar, baking powder, flour and salt in a large bowl. In a smaller bowl, beat together the egg and vanilla extract then add it to the flour mixture bowl. Stir to combine. Take your softened butter and cut it into small pieces. Crumble it into your mixture. I prefer to use my hands to do this but you can use a fork or a pastry blender.

    Take your parchment lined 8x8" pan and press ¾ of the crumb mixture into the bottom of the pan to form a nice crust.

    Set your pan aside and prepare the filling ingredients. Toss them on top of the crust and then crumble the remaining crumb mixture on top of the blueberries.

    Bake on 375 F for 45 minutes, until the blueberries are oozing and jam like and the crumbs are golden.

    Cool before cutting them into squares.
