Preheat waffle iron. Preheat oven to 350.
Mix the flour, baking powder and salt. Stir in the egg yolks, milk, and vegetable oil.
Whisk the egg whites to stiff peaks. Fold the egg whites into the waffle mixture.
Make your waffles according to the manufacturers instructions.
Cut the waffles into chip shaped triangles. Place on a baking sheet and bake at 350 for 30 minutes or until crispy, flipping once half way through.
Whisk together the evaporated milk and corn starch in a large frying pan off the heat.
Bring this mixture to a simmer. Remove from heat and stir in the maple syrup.
Add the cheese and stir to combine. Turn the heat to low and bring the pan on and off the heat to warm very gently and allow the cheese to fully melt. If you heat too aggressively the sauce may separate.
Spread your waffles out on a platter and smother them with the cheese sauce.
Add the bacon, avocado, scallions, sriracha, and more cheese sauce.
Serve in the middle of a group of friends and give everyone a fork to dig in!
