To make the candied bacon:
Line up the bacon slices side by side on the prepared baking sheet. Brush both sides of each piece with maple syrup and cover both sides with brown sugar.
When the bacon is cool, roughly chop it into
To make the waffles: Preheat a waffle iron and grease with a little butter or nonstick spray. Meanwhile, in a large bowl, whisk together the flour, sugar, baking powder, baking soda, cinnamon, salt, and ginger. Add the candied bacon bits and stir to combine.
In a medium bowl, whisk together the egg yolks, buttermilk, melted butter, and vanilla.
In the bowl of a stand mixer fitted with the whisk attachment (or in a medium bowl, using a handheld mixer), beat the egg whites until soft peaks form.
Add the egg yolk mixture to the flour mixture and mix well. Fold in the egg whites.
To cook the waffles: For each waffle, ladle about ⅓ cup of the batter onto the waffle maker, spreading it almost to the edges. Close the lid and cook for 3 to 5 minutes, or according to the manufacturer’s instructions. Serve warm, with maple syrup.
