Whisk wet ingredients together for brownies
In a separate bowl whisk dry ingredients, then add into wet mixture
Spray a mini muffin pan with nonstick spray
Fill mini muffin pan 3/4 way full with brownie batter
Bake at 350 for 12-14 minutes
As soon as you take them out of the oven use the back side of a 1 tsp measuring spoon to create an indent in the brownie
Allow to cool 10 min, then remove from tray and onto a wire cooling rack
Whip your icing with colorant(s) of choice until desired shade is achieved
Pipe into the divots of your brownies
Decorate with sprinkles as the "bubbling cauldron" and pretzel sticks
Enjoy!
