(Cupcake burgers are cupcakes that look like mini burgers... not burgers that look like cupcakes)
Well here's how you do it!
Step 1:
Make vanilla cupcakes.
Step 2:
Put brownie mix into the cupcake trays (with paper). These will create little brown discs that will function as your "patties."
Can't go wrong with Betty Crocker. Well... you can... if you don't do exactly what she says on the box. So do what the woman says.
Step 3:
Make red and yellow icing by putting food dye into two separate bowls of white icing.
Step 4:
Cut up little squares of green fruit roll up. This is optional. You can just use green icing instead if for some weird reason you don't like fruit roll ups, even though they are magical.
Step 5:
Assemble the burger cupcakes! Cut your vanilla cupcakes in half, spread red (or yellow) on the top of the bottom half for the ketchup (or mustard). Then put the brownie patty on top, followed by the yellow (or red) icing. Then comes the green fruit roll up square for your lettuce, topped all off with the top "bun." You can put in a fancy toothpick as well to add to the burger illusion.
Now if you want to get fancy with this, you can go ahead. Some people put white cupcake crumbs on top to make it look like it has sesame seeds, and I've also seen people who have laid out green icing all fancily to make it look like real lettuce. It's all a matter of how much work you want to put into it.
This could be a possible outcome if you have extreme experience designing baked goods.
As for my adventures with making cupcake burgers... let's just say it involved a bake sale requiring two hundred cupcakes and an entire day's worth of baking and listening to reggae music. Not going to lie, I twitch a little bit every time a Bob Marley song comes on.
Nevertheless, cupcake burger making in moderation is a blast, and certainly delicious!
