In a saucepan over medium heat, combine coconut sugar and maple syrup and heat bubbly and frothy.
Lower heat and add sesame seeds, salt, ground nutmeg, and vanilla extract. Stir continuously for 10-15mins until seeds begin to brown.
Remove from heat and pour sticky mixture onto a silicone baking mat, smoothing it out into an even layer.
Set aside and dry for a few minutes, then remove dry sheet of brittle from baking mat and cut into squares while warm.
Allow a few minutes to cool off before serving.
