Preheat oven to 400 F, line 2 baking sheets with parchment paper.

Measure the almond flour, baking powder, and salt into the bowl of a food processor, blitz to combine.

Add the egg, blitz again until well combined. Set aside.

Measure mozzarella cheese and cream cheese into a microwave-safe bowl. Heat - 30-45 seconds at a time and stirring in between - until cheese has melted.

Add melted cheese mixture to the food processor, pulse until well combined - you don’t want to see any sections of unmixed cheese.

Use wet hands to pinch off 1 inch sized pieces of dough - or about 24 equal pieces. This works best while the dough is still warm - you can reheat it slightly in the microwave if you like.

Form each piece into a round that’s about 2" across, and ¼" in thickness. Keep your hands and work surface wet, as it can get sticky!

Place formed rounds on prepared baking sheets, prick all over with a fork. If using sesame seeds, sprinkle over the dough rounds and very lightly press to adhere.

Bake in the preheated oven until lightly golden brown - about 8-10 minutes.

Remove from oven, allow to cool slightly before eating.
