RAINBOW CUPCAKES

A year and a half ago I was at a pretty low point in my life. My sister had passed away unexpectedly and my dad and my mother-in-law had both been diagnosed with cancer. Overall I think I’m an optimistic person but I found myself in an unfamiliar place filled with cynicism and doubt that life was nothing more that hurt and trials.

Time heals all things…most things. Today my dad and mother-in-law are both cancer free and realizing that my sister is gone is…well… bearable. I know I will see her again. It’s just that it feels like forever before I will. I am in a much better place.

HOW TO MAKE RAINBOW CUPCAKES

  1. Make cupcake batter.
  2. Divide batter into small bowls according to how many different colors you are using usually 5 or 6. 5 colors and it worked out to a little over 1 cup for each color.
  3. Use food coloring to color batter to desired intensity. Wilton brand gel food coloring have the brightest colors and wont thin your batter. They can be found at Walmart or Michaels.
  4. To get a layered stripe like I used, you’ll want to put a spoonful of each colored batter in the cupcake liners one at a time. The batter is thick, so it won’t spread on it’s own. A great tip is to set out a little bowl of water where you’re working. Dip your finger in the water and then gently spread the batter out. The water will make it so the batter doesn’t stick to your fingers.
  5. Another tip is to use a measuring spoon and some water to measure out how many teaspoons/tablespoons are going to fit in your cupcake. Then divide that by how many colors you have so you know how much of each color to use for each cupcake. For my 5 colors, it worked out perfectly with 2 t of each color in each cupcake. So I put in 2 teaspoons of blue in the bottom of each cupcake and spread it out with my finger. Then I put in 2 teaspoons of green on top of that, then yellow, etc.
  6. Bake them according to the package directions, until a toothpick comes out dry.
  7. Frost with your favorite frosting. Fancy it up by putting the frosting in a ziplock bag or piping bag. Cut of the corner of the side of the bag and you have an instant frosting decorating bag.
  8. For the frosting: In a large bowl, add butter and powdered sugar and beat until light and fluffy.
  9. Add the coconut extract (if using), vanilla extract, and a pinch of salt. Mix until combined.
  10. Gradually add milk (you may not need all of it) and beat for 2-3 minutes until fluffy.
  11. Frost the top of the cupcakes. Add rainbow sprinkles if desired.
