Using a spoon, stir the Sunbutter well - to incorporate any oils that have floated to the top of the jar. Mix until smooth and oil seems to have "disappeared into the sunbutter."
In a small mixing bowl, measure out the sunbutter and sugar and add the egg. Mix well until thick dough forms and all ingredients are incorporated.
Place in the fridge for at least 10 minutes.
Preheat oven to 350 F. Line a baking sheet with parchment paper.
Add TBSP size dollops onto the parchment paper, then make criss-cross design with fork while flattening the cookie dough.
Place in preheated oven for 10 to 11 minutes, remove from oven and place immediately on cooling rack. Let cool about 10 minutes before eating.
Serve Sunbutter Cookies as snack or dessert.
