It often happens when chocolate is left in a hot place.
Why Does Chocolate Bloom Make Candy Bars Look Dusty?
Updated Aug. 09, 2021
If you’re anything like me, your mind is already one season ahead—I’m talking fall, baby! I’ve already got my eyes on the new HomeGoods Halloween collection. It’s never too early for a bunch of cutely carved pumpkins around the house, you know what I mean?
And what else comes with Halloween but candy? I hold trick-or-treating near and dear to my heart. But sometimes I open up a Snickers bar to see a weird dusty coating. That strange dust or powder on chocolate is called chocolate bloom.
What Is Chocolate Bloom?
The explanation for chocolate bloom is simple food science—it happens when the fat in chocolate separates from the rest of the candy. When chocolate is left in a warm place and melts, the fat in the chocolate (also known as the cocoa butter) will separate from the rest of the ingredients as it cools and reforms. Then, as the fat rises to the surface, it creates that white, dusty film.
In a similar process known as sugar chocolate bloom, the sugar will crystallize due to excess moisture. When that happens, you’ll typically see a speckled appearance on top of the candy bar.
No doubt you’ll come across a Snickers, Milky Way or Hershey bar with a weird bit of white dust or an off-colored section. Here’s what to do when you find one.
Is Bloomed Chocolate Safe to Eat?
The short answer is yes, it’s safe. The taste may end up a little off, but it’s edible nonetheless.
If you’re uneasy about eating bloomed chocolate, but don’t want to waste the candy, use it for baking. Drop ’em into candy bar cookies, crush the candy bars to top chocolate-covered pretzels or stir pieces into candy bar brownies!
