Just in time for St. Patty's Day!!
Simply make a white cake from a box or from scratch.
Divide the batter into 6 smaller bowls and add food coloring. Now, if you want colors as vibrant as these, I recommend you use the Wilton Food coloring gel which you can find in craft stores. The colors are phenomenal and stunning!
Spoon a little bit of each color into your cupcake liners....and bake.
Then....to borrow the phrase from Skittles....."taste the rainbow...."
