This Maple Blueberry French Toast Bake is a crowd-pleasing variation of French Toast from our cookbook, What’s for Lunch?. Instead of dipping individual slices of bread into an egg mixture and frying them, we bake up a pan full of bread cubes with a delicious maple custard mixture and blueberries. If you don’t have blueberries, substitute cranberries or diced apples, or whisk 1 cup mashed squash or pumpkin in with the egg mixture!
