Christmas Tree Rice Krispie Treats

Grease a 9x13 baking pan with cooking spray.
In a large sauce pot or Dutch oven, melt the butter over low to medium heat on the stove.
Stir the vanilla extract and salt into the butter.
Add the mini marshmallows to the melted butter mixture, stirring until the marshmallows have fully melted.
Remove the mixture from the heat, and quickly stir in the Rice Krispies cereal.
Spread the Rice Krispies mixture in the prepared baking pan.
Cut out Christmas tree shapes with a Christmas tree cookie cutter, and place the Rice Krispie trees on a wire rack to cool completely.
For tinsel, pipe marshmallow cream back and forth on the trees, or pipe it onto the back of Sour Punch Twists (or Straws) to hold them on the trees.
Use M&M's Minis, spice drops, and sprinkles as ornaments for the trees. Cut spice drops in half, which will give you a sticky side you can stick onto the Christmas trees; or use a little marshmallow cream to hold the candies in place.
When you're all finished decorating, have fun serving and eating these festive treats!
