Start by preheating your oven to 375F. Lightly grease an 8"x10" baking dish.
Combine in a large bowl, the milk, maple syrup, eggs, cinnamon, salt, and vanilla. Whisk until smooth and set aside.
5 large Eggs, ⅓ cup Maple Syrup, 1 teaspoon Vanilla, ¾ cup Milk, ½ teaspoon Cinnamon, ¼ teaspoon Salt
Use your hands to tear up the croissants into 2-inch pieces.
6 Croissants
Add the croissant pieces to the bowl of egg mixture. Toss them around, so they may evenly absorb the mixture.
Place half of the soaked croissant on the bottom of the prepared baking dish, enough to cover the bottom. Sprinkle the diced apple, ½ cup of the cheddar cheese and ¼ cup of the pecans, evenly over the croissants.
¾ cup Sharp Cheddar Cheese, 1 medium Apple, ½ cup Pecan Pieces
Cover the filling ingredients by placing the remaining soaked croissant pieces evenly on top.
Sprinkle the other half of the pecan pieces and the remaining ¼ cup of cheddar cheese on the top.
Place the baking dish in the preheated oven. Bake for 15 minutes, turn the dish around and bake for another 5 minutes.
