When you make fudge, a rich, dense candy made from sugar, butter, and milk or cream. Also known as soft chocolate candy, it’s meant to melt on your tongue—not chew like gum or crack like brittle. But too many people end up with fudge that’s too soft, too hard, or grainy, and they have no idea why. The problem isn’t the recipe. It’s the mistakes most bakers make without even realizing it.
One of the biggest fudge mistakes, overheating the mixture. Fudge doesn’t need to boil for minutes. It just needs to hit the right temperature—usually around 234°F (112°C)—and then cool properly. Boiling too long turns it into hard candy. Not boiling enough leaves it too sticky. You don’t need a candy thermometer to get it right, but if you skip it, you’re gambling with your fudge. Another common error is stirring after it cools. Once you take it off the heat, you stop stirring. Stirring while it cools forces sugar crystals to form, and that’s what makes fudge grainy. It’s not magic—it’s physics.
Then there’s fudge with condensed milk, a shortcut version that’s easier but still prone to errors. People think because it’s simpler, they can skip the cooling step. Nope. Condensed milk fudge still needs to cool to room temperature before you stir. If you stir it while it’s hot, it won’t set right. And storing it in a warm kitchen? That’s a fast track to sticky, melted fudge. It doesn’t always need the fridge, but if you live somewhere humid or hot, chilling it is the smart move. You also can’t just wrap it in plastic and toss it in the pantry. Fudge breathes. It needs to be in an airtight container with parchment paper between layers, or it’ll dry out or stick together.
And don’t forget the fudge storage, how you keep it after it’s made. If you leave it out too long, it absorbs moisture and turns gooey. If you refrigerate it without sealing it properly, it gets icy and loses flavor. The best way? Cut it into squares, layer them with wax paper, and store them in a cool, dry place. It lasts weeks that way. Freeze it? Sure. But thaw it slowly in the fridge, not on the counter. Rushing it ruins the texture.
Most of these mistakes come from treating fudge like a cake. It’s not. You don’t beat it. You don’t fold in eggs. You don’t preheat the oven for 30 minutes. It’s a candy. It’s about heat, timing, and patience. Get those right, and you’ll never have chewy, grainy, or crumbly fudge again. Below, you’ll find real fixes from people who’ve been there—troubleshooting tips, storage tricks, and simple ways to save a batch that went wrong.
