Ingredient Notes

  • Powdered Sugar – You’ll want to use powdered sugar to make your royal icing, which is sometimes known as confectioners’ sugar or icing sugar. You cannot substitute granulated sugar or other types of sugar, as they will not dissolve properly and will give the icing a grainy texture. 
  • Meringue Powder – Meringue powder is a baking ingredient primarily used as a substitute for raw egg whites. It’s a fine, white powder made from dried egg whites, sugar, and added stabilizers, such as cornstarch, and sometimes includes flavorings or acidity regulators like citric acid. I prefer AmeriColor brand meringue powder, which I find on Amazon, but you may be able to get it at craft stores or cake decorating stores as well. 
  • Water – Use room temperature water for best consistency. The amount of water can be adjusted based on desired icing thickness; start with less and gradually add more.
  • Vanilla or Almond Extract – This adds flavor to the icing. You can choose either based on preference, but ensure it’s pure extract for the best taste. Artificial flavors can leave a chemical aftertaste, especially when the recipe is not being cooked 
  • AmeriColor Gel Food Coloring – Gel food coloring is preferred over liquid as it provides vibrant colors without thinning the icing. Start with a small amount and add more as needed to achieve the desired color.

For achieving the perfect consistency in royal icing, the amount of water added is key. Start with the lesser amount of water and gradually add more, if necessary, mixing well after each addition. This gradual approach allows you to reach the desired consistency without accidentally making the icing too thin, which is particularly important for intricate piping work where a stiffer icing is needed. Remember, it’s much easier to thin out a thick icing than to thicken a runny one.

Recipe FAQs

Why is my royal icing not hardening?

This can be due to high humidity, too much liquid in the mix, or not beating it long enough. Ensure you mix it to the right consistency and allow enough drying time in a low-humidity environment.

How long does royal icing last?

When stored in an airtight container, royal icing can last up to 2 weeks at room temperature. 

Can royal icing be frozen?

Yes, it can be frozen for up to 2-3 months. Thaw in the refrigerator and then re-whip before using.

How do I fix royal icing that is too thick or too thin?

If too thick, gradually add more water, a teaspoon at a time. If too thin, add small amounts of powdered sugar until the desired consistency is achieved.

Why am I getting bubbles in my royal icing?

You typically will get bubbles in your royal icing if it is too thin or has too much air incorporated. After thinning out my royal icing, I tap the bowl on the counter a few times to pop any bubbles. Also, if I see any bubbles when decorating the cookies, I use a toothpick or scribe to pop the bubbles before the royal icing dries. 

How long does it take royal icing to dry?

You don’t want to rush the process, but I find that my flood icing takes about 4-5 hours to dry completely and thicker details will take about 1 hour to dry. I typically like to let my cookies dry overnight at room temperature without being covered up before stacking them and packaging up.

Can royal icing be used for anything other than cookies?

Absolutely! It’s also great for decorating cakes, gingerbread houses, and creating intricate piped decorations.

expert tips

  • Royal Icing Consistencies: Royal icing consistency can make or break your cookie decorating. I personally like to use the same consistency for outlining and flooding my cookies as it just makes the process simpler for me without having to have multiple royal icing consistencies for this step. I like to use a “15-second rule for my outline and flood icing, meaning when you lift a spoonful of icing and drop it back into the bowl, the ribbon should hold its shape for 15 seconds before melting back into the icing. For intricate details, I use anywhere from a 20-second or 25-second icing. For these cookies, I used 20-second icing. 
  • Gradual Adjustments: Always make adjustments in small increments, whether adding water to thin the icing or powdered sugar to thicken it. It’s much easier to control the consistency with gradual changes.
  • Coloring Your Icing: Gel food coloring is preferred as it doesn’t alter the icing’s consistency. Add color gradually, a drop at a time, until you achieve the desired hue. Remember, the color often deepens as it dries.
  • Preparing Your Tools: I personally prefer to use tipless piping bags. However, if I’m doing something that requires a specific shape, I’ll use a piping tip, like a leaf tip or small star shape. However, you can use a small round tip (Wilton #2 tip is the most versatile tip I have used in the past) for outlining and flooding the cookies if you prefer. Keep a paper towel or reusable towel nearby to clean off the tip frequently. This will keep your cookies looking very professional and clean. 
  • Keep it Covered: Royal icing dries out very quickly. Place a wet paper towel over your bowl of royal icing while it is not being used so that the top does not dry out and crust over.
  • Piping Technique: When outlining, keep the tip slightly above the cookie surface for a cleaner line. Apply steady pressure to the piping bag and let the icing fall onto the cookie, guiding it rather than dragging it.
  • Flooding Technique: After outlining, use the same icing to fill in, or “flood,” the area. Use a toothpick, scribe tool, or the tip of your icing bag to spread the icing to the edges and pop any air bubbles.
  • Use a Scribe Tool: A scribe tool or toothpick is handy for popping air bubbles and helping icing settle into tight corners when flooding cookies.

Storage instructions

  • Room Temperature: Store royal icing in an airtight container at room temperature for up to 2 weeks. Place a piece of plastic wrap directly on the surface of the icing before sealing the container to prevent it from drying out or forming a crust.
  • Freezer Option: Royal icing can be frozen for up to 2-3 months. To freeze, place it in an airtight container or a zip-top freezer bag. If using a container, make sure to put a layer of plastic wrap directly on the icing’s surface before sealing. If using a zip-top freezer bag, press out all of the extra air before using.
  • Thawing Instructions: To use frozen royal icing, first thaw it in the refrigerator overnight. Once thawed, the icing might separate or become slightly runny. This is normal. Simply re-whip it using an electric mixer on low speed until it reaches the original consistency.

Ingredients

  • 4 cups powdered sugar (480g)
  • 3 tablespoons meringue powder (20g)
  • 6-10 tablespoons water (90-150g)
  • 1 teaspoon vanilla extract (or almond extract)
  • AmeriColor gel food coloring (for decorating)

Instructions

  • In a bowl of an electric mixer fitted with the whisk attachment, combine the powdered sugar, meringue powder, 5 tablespoons of water, and vanilla extract.
  • Mix for 1-2 minutes on low speed, scraping down the sides to make sure everything has been incorporated. This will help ensure you also don’t get a big cloud of powdered sugar all over your kitchen.
  • Turn the speed to medium-high, and mix an additional 3-4 minutes until the ingredients are well blended, the royal icing has increased in volume, and the icing has a relatively matte finish. Note, if you’re using a hand mixer instead of a stand mixer, this will take closer to 8-10 minutes. The royal icing will be thick; This is the base consistency to start with. Royal icing dries out quickly, so make sure it is covered at all times with a wet paper towel or wet kitchen towel unless it’s in a pastry bag.
  • I usually add about 1 teaspoon more of water for a good outline icing (I use a 15-second rule, meaning if you drizzle the icing with a spoon or spatula over the bowl of icing it will melt back into the icing in 15 seconds. Depending on how thin your icing needs to be you can add anywhere from 1-4 more tablespoons of water, as needed. Go slowly, adding ½ teaspoon at a time at most, as it’s easier to thin out your icing than it is to make it thicker again.
  • If your royal icing is too thin, you can add small amounts of powdered sugar to thicken it, but I prefer to add just small bits of water at a time to ensure my royal icing doesn’t get too thin.
  • Add gel food colorings a little at a time as needed to color the icing. The color will deepen as it sits.

Notes

  • For outline/flood consistency of royal icing, I like to use one consistency because it is more efficient for more and requires less pastry bags. For outline/flood consistency, I use a 15-second icing. 
  • For more detailed work, I use between 20-second and 25-second icing depending on how much detail I am looking for. 
  • If you’re looking to use royal icing to create a gingerbread house, you’ll want it to be really thick to assemble the walls. Start with the base consistency and go from there. You want the icing to be pipable so you don’t hurt your hands while assembling the house, but you also want to make sure it’s really thick so it’s strong. You may need to add a few sprinkles of water to the base consistency to make it a little easier to work with for gingerbread house assembling. For decorating, use 20-second to 25-second royal icing for intricate details. You can use something a little thinner if you are spreading onto candies for decorations. 
  • I use tipless piping bags 90% of the time. I just cut a small hole in the piping bag and use it from there. I will use piping tips if I want a specific shape for detailed work, like a small star tip, a leaf tip, etc. 
  • I prefer using gel food coloring instead of water-based food coloring because they are more vibrant and require less food coloring added to the royal icing. I find the water-based food coloring changes the consistency of my royal icing too much. AmeriColor gel food coloring is my favorite brand, as it is gluten-free and I love the squeeze-bottle aspect of it rather than other brands which have a screw-on top and can easily get messy.
