1. Preheat oven to 375°F. Preheat your waffle iron. Arrange bacon in a single layer on a rack over a baking sheet. Place in the upper third of the oven and bake until bacon is brown and crispy, about 10 to 15 minutes. Remove from oven & once cool, chop the bacon into bite size bits and set aside.
2. In a large bowl combine flour, baking powder, baking soda, salt and brown sugar. Whisk to blend. In a medium bowl, whisk together eggs, butter, buttermilk and vanilla extract. Add the wet ingredients to the dry ingredients and stir. When almost fully incorporated, add the bacon and mix only until the dry ingredients are moistened in the batter. Cook according to your waffle baker instructions.
3. Serve with maple syrup
