Preheat your waffle iron the the highest setting.
In a large bowl, whisk together the flour, sugar, cornstarch, baking powder, soda and salt. In a smaller bowl, whisk together the buttermilk and vanilla extract. Separate the egg, placing the egg white in the bowl of your electric mixer and the egg yolk in with the buttermilk.
Beat the egg white on high speed until stiff peaks form.
Stir the buttermilk and egg mixture into the dry ingredients until just combined. Stir in the melted butter until it’s combined – it will take a minute or two to incorporate. Fold the stiff egg whites into the batter and then fold almost all of the crispy bacon bits (I reserve some for topping) into the batter. Spoon 1/3 to 1/2 cup of batter into the hot waffle iron. Cook until crunchy and golden, about 2 to 3 minutes a piece.
In a high-powered blender, puree the frozen acai puree with the blueberries, banana, coconut milk and vanilla extract. You want it to be “scoopable,” so scoop a spoonful and place it in the center of each waffle. Build your sundae! Top with sliced banana and peach, blueberries, strawberries and cherries, a sprinkle of granola, drizzle of cashew butter and shake of coconut. Top it off with some fresh mint and a cherry. Devour immediately.
