In the bowl of a stand mixer, preferably fitted with a paddle attachment, combine the SunButter, butter, and both sugars. Mix on low until everything is incorporated.
Add the eggs, vanilla, and salt, and mix on low until just combined. Add the flour and mix until the batter starts to form on the paddle or beaters.
Divide dough into two equal portions. Roll each portion to a thickness of about ¼ inch between two pieces of parchment paper. Keep the dough between the parchment and stack on a baking sheet. Refrigerate the dough for 1 hour before cutting.
Preheat the oven to 350 degrees. Line 2 baking sheets with parchment paper or silicone baking mats.
Cut the dough with leaf (or any!) shaped cookie cutters and place on the prepared baking sheets.
Bake for 8-12 minutes or until set and golden. Let cool completely.
Decorate with chocolate cookie decorating icing, as desired.
