Cute Hamburger Cupcakes

Time: 90 minutes
Yield: 30 servings
Recipe idea from the lovely Bakerella

1 9x13 pan brownies (I used this recipe)
30 vanilla cupcakes (I used this recipe)
1 batch buttercream frosting (I used this recipe)
red, yellow and green food coloring gel (I found some at Walmart on the cake decorating aisle)
cupcake liners
3 cake decorating bags
3 cake decorating tips (any medium-sized tip will do)
sesame seeds

1. Make yourself a pan of brownies. If you have a favorite brownie mix, it would work out well. You want something that is nice and chewy. I opted to use this recipe
2. Make yourself some cupcakes, I used this recipe here. As a side note, my sister Mary mentioned to me that she buys unfrosted cupcakes frequently at the Sams Club bakery. She freezes them until she needs them and then frosts and fills them with whatever she likes. Great idea, right. :) 
3. While your brownies and cupcakes cool completely, make a batch of buttercream frosting. Recipe found HERE. Separate the frosting into three bowls and use the food coloring gel to color each bowl red, green and yellow. 
4. Snip the ends of your cake decorating bags and drop a tip into each one. Fill each of them with frosting. 
5. Using a sharp serrated knife slice each cupcake in half. 
6. Using the bottom half of the cupcake as a pattern, cut a circle shape out of the pan of brownies. You may want to shape it a bit with your fingers to help it become a round circle. Place it o top of the cupcake bottom. Add a little swoop of red food coloring, a touch of yellow and a swoosh or two of green. 
7. Carefully place the top half of the cupcake onto the frosting. 
8. Brush a little bit of water over the top of the cupcake and immediately sprinkle some sesame seeds on top.
