Preheat oven to 300°.
Trim crust from bread; discard crust. Cut bread into 2-inch cubes. Place bread cubes on a baking sheet. Bake at 300° for 30 minutes or until bread is toasted, turning occasionally.
Increase oven temperature to 425°.
Heat butter in a large nonstick skillet over medium-high heat. Add corn and garlic to pan; cook 4 minutes or until lightly browned, stirring occasionally. Combine milk, egg substitute, salt, and black pepper in a large bowl, stirring with a whisk.
Add corn mixture and cheese to milk mixture, and stir to combine. Fold in the bread cubes.
Pour corn mixture into a 2-quart baking dish coated with cooking spray; let stand 10 minutes. Bake at 425° for 40 minutes or until puffed and set.
