These are delightful and simple. They don't take any special equipment. This is all there is to it:
Make a batch of brownies. Let them cool.
Cut them into desired sizes and shapes.
Stick a popsicle stick in each and put them in the freezer.
Get a tub of frosting. We used fudge.
Melt the frosting and dip each brownie in the frosting. Let them drip for a moment and then poke the stick handle into Styrofoam to keep the treat vertical while it dries. For a thinner coating, use a warmer frosting. A cooler frosting will give you a thicker coating.
Once the frosting is set, drizzle the pops with multiple colors of icing made with powdered sugar. You can also decorate them with sprinkles or other decorations.
