Preheat oven to 170°C (340 °F) and line a 20×20 cm (8×8 inch) baking pan with baking paper.
Crack the eggs and separate the egg yolks from the egg whites. In a bowl whisk the egg whites until a foam forms. Test the foam by carefully turning over the bowl. If it stays in the bowl, it’s good to go. Set aside.
Whisk together the wet ingredients with a hand mixer until well combined. Mix almond flour with baking powder and salt. Add to the wet ingredients and whisk until a dough forms.
Now carefully fold the egg white foam into the dough until combined.
Transfer the dough into the baking pan and distribute evenly. Bake for 30-35 minutes until slightly browned.
Let cool, sprinkle with some icing sugar and slice into bars.
