How to Store, Freeze & Reheat

Decorated cookies with royal icing should be left out at room temperature for at least 6 hours to dry completely. Once dry, they can be stacked in airtight containers with parchment paper between layers – they’ll keep for up to 2 weeks.

For longer storage, you can freeze undecorated cookies for up to 3 months. I love serving these at parties or gifting them – they look stunning and taste even better.

🛒 Ingredients (Check Off As You Measure)

4 cups powdered sugar, sifted
3 tablespoons meringue powder
9 tablespoons warm water
1/2 teaspoon vanilla extract (or clear vanilla for pure white)
Pinch of salt

🍳 Step-by-Step Instructions

In a large bowl, combine the sifted powdered sugar and meringue powder. Whisk to distribute evenly.
Add the warm water and vanilla extract. Using a hand mixer on low speed, beat until the mixture is smooth and glossy, about 3-4 minutes.
If you're using a stand mixer, use the paddle attachment and mix on low for the same time. The icing should hold a stiff peak when you lift the beater.
For flooding consistency, add water a teaspoon at a time until the icing ribbons off the spoon and smooths out within 10 seconds. For piping, keep it thicker.
Cover the bowl with a damp cloth or plastic wrap when not in use to prevent drying. Color and use immediately or store in an airtight container.

👩🍳 Chef Elena’s Kitchen Notes & Storage

Always sift your powdered sugar – it makes the icing silky, not gritty. For the longest shelf life, store royal icing in an airtight container in the fridge for up to 2 weeks; just re-whip before using.
