Grease muffin tin thoroughly to avoid any sticking. Preheat oven to 350 degrees.
Prepare brownie mix according to package directions.
Pour brownie mix into muffin tin, filling about 2/3 full.
Bake according to package directions or until a knife placed in center of brownie comes out clean. Mine took 25 minutes to fully cook through.
Allow to cool 5 minutes in the pan and then remove and cool the rest of the way on a cooling rack. If any brownies stick to the side, slide a knife around the brownie and it should easily pop out then.
Once completely cooled, pipe green icing on the top of the brownie and down the sides to look like a green potion that has spilled over the edge.
Sprinkle green sprinkles on top of the icing to mimic bubbles and some of the creepy witches ingredients! Even add a pretzel stick, Tootsie Roll, or black licorice as the stirring spoon!
