Blueberry Squares

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Place chickpeas, 1/2 cup rolled oats, 1/2 cup brown sugar, 1/4 cup olive oil, 2 teaspoons vanilla extract, baking powder, 1/4 teaspoon baking soda, and salt in a food processor. Blend to a dough-like consistency; press into an 8×11-inch baking pan.

Step 3
Bake crust in the preheated oven until crisp and lightly browned, 20 minutes.

Step 4
Combine blueberries, white sugar, and lemon juice in a saucepan; cook over medium-low heat until blueberries have reduced, 10 to 15 minutes. Whisk cornstarch and water together in a small bowl; stir into blueberry mixture. Cook until mixture thickens, 2 to 3 minutes. Pour blueberry mixture onto the cooked crust.

Step 5
Mix 1 1/2 cup rolled oats, flour, 1/2 cup brown sugar, 1/4 cup olive oil, 1 teaspoon vanilla extract, and 1/2 teaspoon baking soda together in a large bowl until bread crumb consistency. Sprinkle over blueberry mixture.

Step 6
Bake in the preheated oven until blueberry filling is bubbling and crumble topping is lightly browned, about 20 minutes. Cool and cut into squares. Store leftovers in refrigerator.
