Sheet Pan Blueberry Pancakes

Preheat the oven to 350 degrees F (175 degrees C). Line a large sheet pan or jelly roll pan with parchment paper. Spray the parchment paper with cooking spray.

Mix the baking mix, milk, eggs, vanilla extract, and cinnamon together in a large mixing bowl. Pour onto the parchment paper-lined pan. Sprinkle blueberries evenly on top of the batter.

Bake in the preheated oven until golden brown, 15 to 18 minutes.

Remove the pan from the oven, then lift the parchment paper with the pancake from the pan and set it onto a cutting board. Slice the pancake into squares using a pizza cutter or into your desired shapes with a cookie cutter.
