Ingredients

bag of powdered sugar, jar of meringue powder, box of food coloring, bowl of vanilla and salt on a grey countertop.

The ingredients for rainbow sprinkles are the same as the royal icing you use to decorate sugar cookies. The key for me is the meringue powder, which is a mixture of egg whites, sugar, and a stabilizer like cornstarch. It is also possible to make royal icing with egg whites, but I prefer the simplicity of meringue powder.

 

Feel free to add use any food coloring – natural or artificial – and any flavorings you like!

Recipe tips and tricks

The hardest part of learning how to make sprinkles (and it’s not that hard!) is figuring out when you’ve beat the sprinkle mixture enough. Your goal is a glossy mixture that forms very firm to stiff peaks.

The second hardest part of this rainbow sprinkle recipe is deciding when you’ve got the perfect color for your rainbow, and you should stop messing with them any more!

Finally, then you’ll have to decide whether to pipe your sprinkles in long lines using piping bags or sandwich bags with a hole snipped off the side. Using piping bags and a piping tip will give you more uniform sprinkles. Or go wild and pipe rainbow chips instead of rainbow sprinkles!

Equipment

  • 1 Stand mixer or hand mixer

Ingredients

  • 2 cups (240 grams) powdered sugar
  • tablespoons (14 grams)meringue powder
  • 1 pinch salt
  • 3 to 5 tablespoons room temperature water
  • 1 teaspoon vanilla extract
  • food coloring as desired

Instructions

  • Lay out a sheet of parchment on a baking sheet and ready six small piping bags fitted with round tips or sandwich bags.
  • Mix together the powdered sugar, meringue powder, and salt in the bowl of your stand mixer or a medium-sized mixing bowl.

  • Add three tablespoons of water and the vanilla to the powdered sugar mixture and beat until the mixture is glossy and you get very firm or stiff peaks so that when you turn the beater upside down, the mixture remains upright or only the tip bends over. If it seems too thick, add a bit more water, about a teaspoon or so at a time.

  • For rainbow sprinkles, divide the mixture into six small bowls and use food coloring for red, orange, yellow, green, blue, and purple sprinkles. Mix until there are no more traces of white, and cover 5 of the bowls with plastic wrap.
