Instructions 

  • Step One: Mix Powdered Sugar and Butter
  • In a medium bowl mix powdered sugar and butter with an electric mixer at low speed until fully combined. You may also use a wooden spoon with you do not have an electric mixer.
  • Step Two: Add Vanilla and Milk
  • Add the vanilla and one tablespoon of milk to the mixture. Mix until fully combined.
  • Step Three: Add in Remaining Milk
  • Gradually beat in remaining tablespoon of milk until the frosting has reached a smooth and spreadable consistency. If the frosting is too thick, add a few drops of milk at a time until it reaches a creamy consistency. If the frosting is too runny, add a small amount of powdered sugar until it thickens up.
  • Step Four: Add the Food Coloring
  • Once the frosting is fully mixed, add the food coloring. It will take approximately 70-80 drops of royal blue food coloring for four cups of frosting to reach the desired shade. If you are making your own royal blue, add 20-22 drops of blue food coloring and six to eight drops of red food coloring. Thoroughly mix the food coloring in the frosting until it is fully mixed. You may add more food coloring if it does not come out your desired shade.

Notes

  • If you already have a favorite buttercream frosting recipe, you can use that to make royal blue buttercream. It is best to follow the ratio of 40 drops of royal blue food coloring for every two cups of frosting. However, you might need to add more to reach a vibrant royal blue food coloring.
  • Though 80 drops of food coloring might seem like a lot of food coloring for four cups of frosting, it will likely be just the right amount to achieve the perfect royal blue food coloring. To put in perspective, 100 drops of food coloring is only about one teaspoon worth.
  • Though royal blue frosting is beautiful, it may cause staining. Make sure to be careful not to get it on any of your clothes, as the blue color may be hard to get off and may even permanently stain clothing. The royal blue color may also stain your lips, tongue, and teeth temporarily.
  • This frosting can be stored in an airtight container for two to three days. It can be stored in the fridge for up to a week and the freezer for up to six months.
  • After being stored, the frosting may separate from the food coloring, so it will likely need to be remixed. The color might also change over time, so you may need to adjust accordingly.
  • Royal blue food coloring also works with cakes, cookies, and most doughs. It adds a vibrant blue color that turns out beautiful when baked. Royal blue is also a great shade of blue to use for any desserts you make for the Fourth of July.
