Hey Besties! This is one of the questions I get most frequently, so we are breaking it down for you today! As a royal icing cookier, a dehydrator is one of the best tools to improve the quality of your icing while also saving a ton of time! Every single cookie I decorate spends time in my dehydrator for all the benefits. It’s a complete game changer for my icing and to free up more time…something every cookier needs more of! The best dehydrator for cookie decorating will depend on you, and several factors but we’ll break it all down for you. Read on to find your next decorating Bestie!
Why do I need a dehydrator for cookie decorating?
If using a dehydrator for decorating is new to you, let’s cover the benefits and answer other FAQs! To start, it greatly speeds up icing crusting, which allows the entire decorating process much faster. Something that can normally take 30 minutes or more to crust, only takes 5-10 minutes with a dehydrator. So if you are decorating many cookies with multiple steps, there’s always cookies ready for the next decorating step, reducing any time wasted. I almost always have all my decorating done in one day and can then bag up my cookies the next day. This ensures my cookies are as fresh as possible for those who are going to enjoy them.
Honestly, I first started using a dehydrator to ensure my cookies could be bagged up sooner but fell in LOVE with it for the difference it makes in my icing. Want to lock in puffy icing? It’s perfect for that. Want to avoid craters? Quick setting your icing is the best way. Want to have a polished sheen to your icing? The dehydrator sheen is unmatched. Want a smooth, polished finish instead of porous icing? Yep, you guessed it…a dehydrator makes a world of difference. Check out this comparison photo that one our group members shared after using her dehydrator for the first time. The only difference between these cookies is that one spent a brief amount of time in the dehydrator. This is why I could never go without my dehydrator for decorating!

Will it dry out my cookie?
The first question we all ask! The good news is that when used correctly for decorating purposes, there is no texture change to your cookie. Why is this? Dehydrators work remove water using a system of heat, fans and vents. But our cookies are made of butter and sugar. But this is why it does wonders for our icing, which DOES contain water! The efficiency in drying your icing, provides all the benefits explained above. It’s the simplest way to elevate your cookies without any extra effort by you.
Can I just use a fan?
Many cookiers use a fan to help dry their icing and it certainly is better than air drying. But still doesn’t compare to the benefits of a dehydrator. I can’t tell you how many cookiers message me saying how shocked they are after using a dehydrator for the first time, after using a fan for years. Many who have only used a fan simply don’t know what they are missing. To each their own, but after working with thousands of cookiers and making thousands of my own cookies, a dehydrator is a tool I’ll always recommend.
Also worth mentioning is that a dehydrator is a much more sanitary method of drying royal icing compared to a fan. I personally don’t use a fan at all for this reason. Lastly, a fan blowing on your cookies will absolutely start to dry out your cookies. Every cookier wants their cookies to be as fresh, soft and moist as possible, so I caution hours of airflow blowing on your cookies.
How do I use a dehydrator for cookie decorating?
Good question! There’s definitely do’s and don’ts for successfully using a dehydrator for decorating. I break it all down for you HERE. It’s super simple and once you start using it, you’ll quickly learn and see all the benefits while avoiding any pitfalls.
What is the best dehydrator for cookie decorating?
Let’s get to the heart of the matter! You’re ready for all the benefits but may be overwhelmed with all the options out there. I get it and that’s why I hear this question so often! The best dehydrator for YOU really depends on the size you want, both in terms of number of trays and tray size, along with price. And before I share several recommendations, here are a few universal truths that make these models the best for decorating purposes.
Airflow
You want a model with the fan in the back or on the side, blowing air horizontally, across your icing. Airflow across the surface of your icing gives you all the benefits while minimizing any effect to your cookie.
Tray accessibility
You’re going to want a dehydrator with trays you can access independently. When using a dehydrator for our purposes, you will have trays going in and out very frequently. And if you have a model with stacking trays, you’re going to constantly be moving trays, which leaves your icing very vulnerable to cracks from all the movement. This is why being able to access each tray independently makes it much easier for you and protects your icing from any damage while crusting.
temperature
Most cookiers, me included, use our dehydrators at 95 degrees F. I would not use dehydrator for decorating over 100 degrees F. You run the risk of basically cooking your icing and will ruin your decorating.
