Sift flour, baking soda, baking powder, sugar, salt, and matcha into a bowl.
In a separate bowl, mix egg yolks, buttermilk, and vanilla until combined. Create a well in the center of the dry ingredients and pour the egg mixture into the center, mixing slowly with a rubber spatula.
Add in melted butter and mix until fully incorporated, being sure not to overmix.
In another bowl, whip egg whites to stiff peaks. Gently fold egg whites into the waffle batter.
Spray your waffle maker with nonstick spray and turn to low/medium heat. Following your waffle maker's manufacturer's instructions, cook waffles until golden brown and crisp. (For a standard waffle maker, about 1/4 cup of batter typically works. Cook waffles for about 2-3 minutes).
Make black sesame whipped cream by adding heavy cream, powdered sugar, and black sesame powder to a bowl. Whip until stiff peaks form.
Top your waffles with black sesame whipped cream, fruit, and any other toppings of your choice. Enjoy!
