Preheat the oven to 200ºC/392ºF.
Prepare one full sheet tray with baking paper or a silpat.
Sift the almond flour, cocoa powder, and confectioners' sugar into a bowl and reserve.
Whip the egg whites to a frothy texture.
Gradually add the sugar and whip to stiff peaks.
Add the whole eggs gradually to the dry ingredients, mixing well after each addition. Mix until smooth and light.
Fold in the sesame paste and sesame until combined.
Once the egg whites have formed glossy firm peaks, add to the egg mixture in 3 stages, folding gently after each addition.
Spread evenly onto the entire sheet tray.
Bake at 200ºC/392ºF for 10-15 minutes (depending on the oven strength).
Check for readiness (firm to touch).
Once baked, remove carefully from the sheet tray and cool on a rack.
Cut into any desired shape to fit the bottom of the chosen mold.
