Sprinkle salt in 2 chocolate bar molds.

In a medium microwave safe bowl, melt chocolate and butter. It is easiest to cut them into chunks first as they melt faster. Microwave for about 90 seconds, stirring every 30 seconds so the chocolate doesn't burn.

Add the powdered erythritol to the chocolate and mix well.

Pour chocolate evenly into 2 chocolate bar molds.

Sprinkles pumpkin seeds on top of chocolate and lightly press down so it is all even.

(optional) sprinkle with a tad bit more sea salt.

Let sit in the freezer for at least 2 hours to set. I keep mine in the freezer and pull out chunks as I want to eat them!
