In a medium-sized mixing bowl, combine the egg yolk with your brown sugar, melted butter and coconut oil, vanilla extract, ground cinnamon, ground ginger, a small pinch of Kosher salt, some Greek yogurt, whole milk, poppy seeds, and ground coconut.
Mix until the ingredients are completely combined.
Add the baking powder, active dry yeast, and all-purpose flour, and stir until the batter reaches a smooth consistency.
Cover the mixing bowl with plastic wrap, and allow the batter to rise in the bowl for roughly 45-60 minutes.
When the batter has almost doubled in size, whisk an egg white with one teaspoon of white granulated sugar until the egg white reaches a stiff peak consistency.
Fold the whisked egg white into the waffle batter that you prepared earlier, and mix using a rubber spatula until the batter is smooth again.
*Note this mixing process will release some of the built-up air pockets in the batter, which is completely normal.
Preheat your waffle iron, and prepare your waffle toppings.
When the waffle iron is hot, add a scoop of batter and allow the waffle to cook until completely golden-brown, or about five minutes.
When your waffles are ready, serve with softened butter, maple syrup, fresh whipped cream, fresh blueberries, fresh strawberries, and a fine sprinkle of confectioner’s sugar.
