Let waffles sit at room temperature for 5 minutes. Cut waffles in half. In a 8x10 baking pan place each waffle half cut side down. There should be two rows of 10 waffle halves.
Pour the blueberries over the waffles, push berries in between waffles if you desire.
In a bowl or large measuring cup combine milk, brown sugar, beaten eggs, cinnamon and nutmeg. Whisk until well combined. Pour egg mixture over prepared waffles, lightly press down waffles into the egg mixture, so that each part of the waffle gets wet.
Cover and set in the refrigerator overnight. If in a pinch let it sit for 4 hours, and it still comes out great.
The next morning uncover dish. Preheat oven to 350 degrees. Make crumb topping while heating.
In a small mixing bowl melt butter in microwave, stir in maple syrup. Add in flour, brown sugar, cinnamon and nutmeg. Mix together until it resembles coarse crumbs. Sprinkle over waffles.
Place in oven and bake 50-55 minutes.
While it is baking make glaze. In a small bowl combine all of the glaze ingredients and stir together until smooth, set aside.
Remove from oven and drizzle glaze over the bake. Serve immediately.
