First prepare your brownies and allow them to cool. I refrigerated mine so that I could get nice clean cuts. When your brownies are ready to be cut, cut off the edges and eat them :) (you could share too, just sayin') and cut the brownies into different sized rectangles and squares. I cut some of the odd shaped leftovers into triangles too.
Eyes
It's important to do this step first to allow adequate time for the glaze to dry. To make the eyes you'll need any variety of Cheerios, some mini chocolate chips, powdered sugar and a little milk. Place the powdered sugar into a small bowl. Using a spoon, stir in some milk, a little bit at a time, until the consistency is good enough for dipping. Start with about a teaspoon and add a couple drops at a time until you get it where you want it.
Drop a few Cheerios into the glaze coating the cereal. Use a spoon to lift the cereal out of the glaze and place on a wax paper lined cookie sheet.
Place a mini chocolate chip, upside down, in the center of each glazed Cheerio. Gently press the mini chip to set. Set aside.
Icing Colors
You could certainly use your own recipe for Royal icing, I have one myself as well. However, because this is such a great recipe for kids to get involved in, using these prepackaged icings is an excellent alternative. They are available in all of the colors that I used by my store only had a few. Therefore, I added some gel food coloring to mix up my colors. This icing is great, squeezes right out of the tube and onto the brownie, love it!
If you have to mix, like I did, you might find the easiest way to apply the mixed icing is with a new paintbrush.
Decorating
Gently press Trix and Cocoa Puffs cereals into the frosted brownies for the monsters' polka dots. Lift the eyes from the waxed paper using a toothpick and gently press onto the frosted brownie. You can use pretzel sticks for arms and legs, and add eyebrows, mouths and hair using decorator gel.
