Preheat the oven to 200 degrees F. Combine the powdered sugar and almond flour in a bowl. Using an electric mixer, beat the egg whites in a clean dry bowl. Slowly add the superfine sugar and beat until the mixture holds stiff peaks, about 7 minutes. Fold the egg whites into the almond flour and powdered sugar mixture carefully. This will add air into the mixture and make it light and fluffy. Spoon the mixture into a resealable bag with a corner cut off. It's easiest to fill your bag if you stand it up in a tall glass and fold the top down before spooning in the batter.

Pipe one-inch-sized mounds of batter onto baking sheets lined with parchment paper. Bake the macaroon for 5 minutes. Remove the pan from the oven and raise the temperature to 375 degrees F. Once the oven is up to temperature, put the pans back in the oven and bake for an additional 7 to 8 minutes, or until macaroons are lightly colored. Cool on a rack. Spread butter cream frosting (recipe below) in between two macaroons to make a burger. Sprinkle sesame seeds on top.
