I have always been a huge fan of Skittles. For as long as I can remember, they have been my go-to treat because I love how chewy and flavorful they are. But recently, I came across something that changed everything: the puffed version of Skittles.
When I took my first bite, I was amazed! They were so light, crunchy, and delicious that I couldn’t stop thinking about them. Since I am someone who loves trying out new recipes and creating homemade versions of my favorite snacks, I knew I had to figure out the secret behind this transformation. I wanted to know exactly how a dense, chewy candy turns into a giant, airy puff.
As I started my research, I realized that the pros use a special freeze-dryer to get that effect. But those machines are expensive! My little brother and I loved the puffed candy so much that I refuse to give up. I am convinced there must be a way to create that “puffed” magic right in my own kitchen without a special freezer.
The mission is officially on—I am going to find the best DIY hack to make these puffed treats for me and my brother. It’s a challenge, but for the love of candy, I’m ready to experiment!
1. What is inside a regular Skittle?
Before the freeze-drying process, a Skittle is made of three main parts:
-
The Sugar Shell: A hard, polished coating made of sugar and food coloring.
-
The Chewy Center: A mixture of sugar, corn syrup, hydrogenated palm kernel oil, fruit juice, citric acid, and thickeners (like dextrin or modified corn starch).
-
Water (The Key Factor): There is a tiny amount of moisture trapped within the chewy center that keeps it soft.
What “comes out” after freeze-drying?
When you put Skittles in a freeze-dryer, two things “come out”:
A. The Moisture (Water Vapor): The machine creates a vacuum and freezes the candy to extremely low temperatures. The tiny amount of water inside the chewy center turns into ice and then immediately into gas (water vapor) through a process called sublimation. This gas is sucked out of the candy by the machine.
-
The chewy center puffs up like popcorn.
-
Since the hard outer shell can’t stretch, it cracks open, letting the white, airy sugar center peek through.

Can You Make It at Home?
The Freezing Version: The “Dry Ice” Sublimation Method
The most authentic way to achieve a freeze-dried crunch at home without a $3,000 machine is the Dry Ice Method. In this process, you place your favorite candies, like Skittles or marshmallows, into a breathable bag and bury them in a cooler filled with chunks of dry ice for about 24 to 48 hours. Because dry ice is extremely cold ($-78.5$°C), it freezes the moisture inside the candy instantly. As the dry ice “sublimates” (turns directly from a solid to a gas), it slowly draws the frozen water out of the candy. This leaves you with a light, airy, and perfectly preserved “puffed” treat that shatters with a satisfying crunch, just like the professional version!
The Microwaving Version: The “Heat Expansion” Hack
If you’re looking for an instant “puffed” fix, the Microwave Method is a popular DIY shortcut, though it works quite differently from real freeze-drying. Instead of removing water through cold, the microwave uses high-speed heat to vibrate the tiny water molecules trapped inside the chewy candy center. This creates internal steam that forced the sugar structure to expand and “explode” outward, doubling the candy’s size in just 30 seconds. While it doesn’t remove 100% of the moisture like a freeze-dryer, the heat brings the sugar to a “hard-crack” stage. Once the candy cools down for a minute or two, it hardens into a crispy, honeycomb-like texture that mimics that famous viral crunch!
