Combine black sesame powder, almond flour, protein powder, baking powder, and salt in a bowl and mix well.
In another bowl, add eggs, almond milk, erythritol, and coconut oil. Mix thoroughly.
Pour the wet ingredients into the dry mixture and knead until you form a dough.
Shape the dough into a round ball, divide into appropriate-sized pieces, and place them on a baking tray or oven pan.
Bake in a preheated oven at 180°C (356°F) for 15-18 minutes, then let cool.
