I got this recipe from a friend a long time ago. These are SOOO fun to make, and the kids love to help. I have made these for St. Patrick's day and added a gold foil covered chocolate 'coin' on top, set on it's edge in the frosting. We also make these for EASTER instead of dyed eggs. I mean, who doesn't like cupcakes??
The batter coloring is a little time consuming, so I just 'cheat' and use a white cake box mix and follow the instructions for baking.
For a more tie-dyed appearance...When you get the layers made, you can swirl a thin swizzle stick through the batter, but not too much, or they'll come out kinda greenish brown :S.
Mix the white cake box mix according to the no-yolk (WHITE) recipe
get 6 small bowls and divide batter evenly into each
add food coloring to make the following colors: purple (blue/red), blue, green (blue/yellow), yellow, orange (yellow/red) and red.
line the appropriate # of muffin tin with paper cups. You may want to spray a small amount of non-stick spray into each paper cup to aid in removal after baking.
carefully layer each color into each cup attempting to get each layer as much over the previous layer as possible (to the edges). Or if you don't care how straight they are..just HAVE FUN. If you want a more tie-dyed look, once the colors are in the cups, slowly and carefully swirl with a swizzle stick, but no too much, or all the colors will over mix .. who wants brownish green cupcakes??
bake according to box mix directions for cup-cakes. while baking - make the FROSTING....
in a small sauce pan, cook the milk & flour together until a smooth paste forms, STIRRING constantly over medium heat. Remove from heat and LET COOL completely. you may even want to put it in the fridge or even freezer to speed up the cooling process.
in another bowl, cream softened butter & shortening together, and gradually add the sugar. Beat until fluffy - this could take up to 5 minutes - but it's well worth the time & effort
add the completely COOLED flour/mix paste to the above butter/sugar mixture, and beat until the consistency of whipped cream (this will take a while)
add vanilla and mix well
spread frosting on cupcakes - store in a closed container in a cool place
