Rainbow Cupcakes for St. Patrick’s Day

I had wanted to make the rainbow cupcakes for a while just to try the technique. I went bold of course since I am pretty colorful and now that I have done this I can say two things. Doing this alone at 10 PM makes the work a lot harder and the other thing is the work is completely worth the effort!

And I just love how the wrapper takes on the colors too its such a neat effect!

Rainbow Cupcakes with Vanilla Buttercream
 
Prep time
Cook time
Total time
 
Recipe type: dessert
Serves: 12
Ingredients
  • 3 eggs
  • 1¾ C. Sugar
  • 1 stick of butter (I use unsalted)
  • ¼ tsp salt (omit if you use salted butter)
  • 1½ TSP Baking Powder
  • 1½ TBS Vanilla
  • ¾ C. Whole Milk
  • 2 Cups Flour (I used my ultragrain flour you can use cake flour or all purpose but not self rising)
Instructions
  1. Preheat oven to 350.
  2. Cream the butter and sugar until smooth.
  3. Add eggs one at a time and mix well
  4. Sift together the flour, salt and powder in a bowl
  5. Add the flour to the wet mixture
  6. Add the vanilla
  7. Add the milk.
  8. Separate into 6 bowls and use food coloring for your rainbow. I used all Wilton gel colors, and my green is KELLY green, my purple is a mix of red and blue.
  9. Put all of the colors into zipper sandwich baggies. Snip a small corner off with scissors to squeeze the batter out. if you want my color scheme use the purple first and work backwards.
  10. After each layer is in, tap the tray on your counter to help flatten the colors (this batter is not runny) and also pop air bubbles
  11. When you have finished, bake them for 25-35 minutes or until toothpick inserted in center comes out clean.

Vanilla Buttercream: This is a hybrid variation of my normal buttercream.

1 stick of butter

1/2 C. crisco

1 TSP vanilla

4 TBS milk

3-4 cups powdered sugar, sifted

 

Cream the shortening and butter on medium. Add the vanilla and the milk. Then add the sugar slowly until it reaches desired consistency. I made a double batch of this because I wanted double frosting on my cakes. I prefer the consistency of this one the most because I can still pipe using my pastry bag and it doesn’t harden really fast.
