Cupcake Decorating Equipment

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog! I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).

Pot of Gold Cupcakes Recipe Tips

Cupcake Making Tips

  • These cupcakes are made using a box of cake mix, and colored green for St. Patrick’s Day!
  • FOOD COLORING! Food coloring is available in various forms. You’re most likely to find liquid coloring in your grocery store, and other types of coloring like gels, pastes, and powders in more specialised cake decorating shops. The cheapest option is liquids, but they can alter the consistency of your frosting and cake batter, so I prefer to use pastes or gels which don’t. A little goes a long way with food coloring gels and you can usually get a much deeper shade than you would with liquids.
  • Remember that you can always add more color, but not take it away. Add a little to start with and add more to get the shade required.
  • Use your choice of cupcake liners – themed to the cupcakes, plain white or black, or a complimentary color.
  • Use an ice cream scoop to equally divide the cupcake mixture between the cupcake liners. Fill them about three-quarters full.
  • The cupcakes should be ready in about 20 minutes – test their doneness by inserting a toothpick into the cakes. It should come out clean when the cupcakes are cooked all the way through. Bake for an extra 2 minutes and check again.
  • Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely before frosting.

Cupcake Frosting Tips

  • When making the frosting you want the end result to be creamy, smooth, and to hold a stiff peak. You may have to adjust the amount of powdered sugar and cream slightly to achieve the consistency you need.
  • Use a piping bag fitted with a large star tip to pipe the swirl on top of the cupcakes.
  • If you feel like you are going to be making a lot of cakes and cupcakes in your future, I think it is worth investing in a set of piping tips so that you know you always have the right ones on hand for a recipe.
  • Do not overfill the piping bag with frosting, and make sure you squeeze the frosting down the bag to expel any air bubbles.
  • If you are not confident with your piping skills you can practice on some parchment paper first and scoop the frosting back into the bag to use on the cupcakes.
