With a buttery cookie crust, a gooey blueberry filling, and a delicious crumble topping, these berry bars are a healthier treat!
Preheat oven to 350 degrees and grease a 9 x 13 pan.
In a food processor fitted with the "S" blade, pulse the crust ingredients through the butter. Alternately, you could use a pastry cutter or your fingers to work the the fat into the dry ingredients until it is well dispersed and no bigger than small peas.
When well combined, add the vanilla and the milk, 1 tablespoon at a time, and pulse a few times to mix. Stop adding milk when the dough can be pressed together with your fingers. HINT: If you like a softer dough, add a bit more milk, if you prefer more crunch, don't!
Mix the blueberries, sugar, and tapioca flour together.
Spread this over the crust, and crumble the remaining cookie crust over the top.
