Preheat oven to 350 degrees.
In a bowl mix the sesame seed butter with the coconut sugar, vanilla extract, baking soda, salt and sesame seeds.
In a separate bowl whisk the egg and egg yolk. After the eggs are whisked, mix them together with the other ingredients until thoroughly mixed together.
Line a couple baking sheets with parchment paper and form about 6 balls of dough per baking sheet (12 total cookies). Smash down slightly with a fork. Then bake 6 at a time for about 10–12 minutes. When they’re done sprinkle some additional sesame seeds on top and let cool. Try not to eat them all in one sitting.
