These are a bit of work from scratch, so using a white cake mix may be a time-saving option for busy bakers. I do suggest homemade frosting . It should be one you really love because these cupcakes hold a tall amount. Using disposable cups or bowls is a good idea when mixing so many different colors of icing. I chose a maraschino cherry as a topper, but you could use a candy cherries found at bulk candy stores.
Sour cream cake
- Preheat oven to 350 degrees.
- In the bowl of a stand mixer fitted with the paddle attachment, cream together butter and sugar until light and fluffy. Add eggs one at a time beating well after each addition. Add vanilla and mix. Whisk together flour, baking soda, baking powder and salt, set aside. in a medium sized bowl, whisk together 1/2 cup milk and 1/2 cup sour cream. Add flour and milk mixture alternately, beginning and ending with flour. Batter will be thick. Fold in color mix-ins, if using.
- Fill cupcake papers with 1/4 cup level measures of batter. Bake for 17 minutes. Let cool and set aside.
This is an estimation of the tinted icing amounts I used for these cupcakes. You’ll need a larger amount of violet versus the much smaller amount of orange.
- Transfer violet icing to a piping bag fitted with a large plain tip (Wilton 2A). I’m confident this could also be done with a zip-top bag with a corner snipped.
- Pipe an even line of frosting around the edge of a cupcake and then lightly fill in the middle with frosting. Repeat process with remaining frostings, getting smaller in diameter as you change icing colors. Repeat process with remaining cupcakes. Top each cupcake with a maraschino cherry.
