24 cupcakes


Choose your measure:



  • 3/4 cup sugar
  • 1/4 teaspoon salt (ONLY if you use unsalted butter)
  • 1/2 cup boiling water
  • 1/4 cup meringue powder
  • 1 tablespoon Vanilla extract
  • 4 cups sifted confectioners' or glazing sugar
  • 2 cups soft butter, 2 cups vegetable shortening, or a combination of both


  1. Preheat the oven to 350°F. Line 24 regular muffin cups with silicone cups or cupcake papers, and grease the cups or papers.
  2. To make the cake: Beat together the sugar, butter, salt, and vanilla.
  3. Beat in the eggs and egg yolks one at a time; it's OK if the mixture looks curdled.
  4. In a separate bowl, whisk together the flour, Instant Clearjel, baking powder, and buttermilk powder, sifting if it's lumpy.
  5. Add half the dry ingredients to the wet ingredients and beat for 1 minute on medium speed.
  6. Add half the milk, then the remaining dry ingredients and beat just until blended.
  7. Scrape the bowl, then add the remaining milk and the candies. Beat on medium speed just until evenly mixed.
  8. Scoop the batter into the pans, filling about two-thirds full.
  9. Bake the cupcakes for 20 to 22 minutes, or until they spring back when touched lightly.
  10. Remove them from the oven, and cool before icing.
  11. To make the icing: Dissolve the sugar (and salt, if you're using it) in the boiling water, and cool to room temperature.
  12. Mix in the meringue powder.
  13. Beat on low speed of an electric mixer for several minutes, until the powder dissolves and the mixture is foamy. Increase the speed and beat until soft peaks form.
  14. On low speed, beat in the vanilla, then the confectioners' or glazing sugar.
  15. Add the soft butter a few tablespoons at a time, beating well after each addition.
  16. Swirl the icing onto the cupcakes.
  17. Store, covered, at room temperature for a few days.
