End of the Rainbow Cupcakes

Today’s post is the first of two that I created for St. Patrick’s Day last weekend! The first is my End of the Rainbow cupcakes. These cupcakes are wonderfully easy with a fun little surprise. Cause what do you find at the end of the rainbow?? A pot of gold, of course!! 🙂

For the cupcakes:

First, assemble your ingredients.

You are going to need:

  • Your favorite chocolate cake recipe
  • Miniature peanut butter cups
  • 12-cup muffin pan lined with paper cupcake liners
  • Cookie scoop

To assemble the cupcakes, take your muffin pan and fill halfway with chocolate batter. (If using a cookie scoop, this is approximately 1 scoop.)

Unwrap the peanut butter cups and put one in each cupcake.

Cover the peanut butter cups with the remaning batter, filling your muffin cups approximately 2/3-3/4 of the way full.

Bake for your recipe’s specified time (about 20 minutes), until a toothpick inserted comes out cleanly. When done, remove from the oven and let cool in the pans for approximately 5 min or until they are cool enough to handle. Remove to a wire rack and let cool for at least 30 min.

For the icing:

First, assemble your ingredients.

You are going to need:

  • 12 fully-cooled cupcakes
  • Your favorite vanilla icing recipe at room temperature (If you’re buying pre-made frosting, 1 tub will be enough for 12 cupcakes.)
  • Food coloring in red, orange, yellow, green, blue, and purple (I use these tho any other gel food coloring will work.)
  • A food-safe, sanitized paint brush (I keep a few acrylic paint brushes clean just for baking. Do not use the same paint brush for food and non-food uses!)
  • Bowl
  • Spoon
  • Chop stick or knife
  • Tall glass (not shown)
  • A small bowl of water to rinse the paint brush between colors (not shown)
  • 1 large icing bag (I use a 16-inch decorating bag because the 12-inch bags are a little too small for a tub of frosting.)
  • A large star tip (I use Wilton’s 1M tip because it creates the big, pretty, swirly cupcake top.)
  • 1 medium icing bag (A 12-inch bag is sufficient.)
  • A “grass” tip (I use Wilton’s 233 tip, which is designed for piping grass.)
  • Sugar sprinkles

Begin by prepping the green icing. Place approximately 1 cup of icing in the bowl.

Add a pea-sized amount of green food coloring and mix in. Set green icing aside.

Start with the rainbow frosting… Place the 1M icing tip in the large bag, narrow end first. Using a pen, mark the bag about half-way along the metal tip. Remove the icing tip and cut the end of the bag off.

Place the icing tip back in to the bag, narrow end first. Fold over the top of the bag to form a cuff. Holding the bag in one hand, begin painting a stripe of each food color on the inside of the bag. This needs to be a generous amount, painted about halfway up the bag.

When colors are all painted in Red, Orange, Yellow, Green, Blue, Purple order, place the bag in a tall glass and fill with icing.

Unfold the top of the bag, and lift it out of the glass. Squeeze the top of the bag and twist it closed. Squeeze a small amount of frosting in to a bowl, until you see the rainbow colors start.

Holding the tip approximately 1/4″ above cupcake top, pipe a small spiral of icing, beginning approximately 1/2″ in from the outer edge and working inward. Continue spiral in to the center of the cupcake. Stop pressure on the bag and pull the tip straight up and away.

Continue with remaining cupcakes.

For the green frosting… Repeat the steps above for inserting the tip and cutting the bag, using the grass tip and the 12″ decorating bag. Place in a tall glass and fill with green icing. Squeeze the top of the bag and twist it closed.

Squeeze bag to form grass. Pull up and away. When icing strand is long enough (about 1/2 inch), stop pressure and pull tip away. Keep clusters close together, so the cake does not show through. Repeat with  remaining cupcakes. Sprinkle with sugar crystals to make them sparkle!

Enjoy!! :D
