Let’s get scientific for a quick second—don’t worry, no lab coat required. Granulated sugar is just sugar crystals; powdered sugar is those same crystals, pulverized into a fine dust. To make the transition, you just need a little elbow grease and a tool that can crush things. Think of it as a tiny, edible rock-crushing operation.
You can use a blender, a food processor, or even a clean coffee grinder. (Just please, please wash that coffee grinder first. Sugar-flavored coffee is a thing, and it’s not a good thing.) A high-speed blender is your best friend here—it turns crystals into clouds faster than you can say “cake emergency.”
The Simple Steps (You’ll Laugh at How Easy This Is)
Step one: pour your granulated sugar into the blender. About one cup of granulated sugar will make about one cup of powdered sugar—a perfect 1:1 swap in most recipes. Add one tablespoon of cornstarch per cup of sugar. This prevents clumping and gives you that silky texture.
Step two: put the lid on tight. I cannot stress this enough. You do not want a sugar cloud explosion all over your kitchen. It’s not a snow globe; it’s a sticky mess.
Step three: blend on high for about 30 to 60 seconds. Pause, shake the blender, and blend again. When you open the lid, a tiny puff of white dust should greet you. Congratulations—you’ve just become a sugar wizard!
