Can You Substitute Light Brown Sugar for Dark Brown Sugar
Okay, let’s pretend you use light brown sugar in a dark-brown-sugar recipe. Here’s what you’ll notice: your cookies will be slightly paler. They spread a tiny bit less.
Your cake will be a bit less moist. Not dry—just less “huggy.” Think of it like choosing a dry martini over a wet one. Both are good; one is just more intense.
And the sweetness? They’re basically identical. Sugar is sugar. The swap doesn’t make things less sweet, just less complex.
The Flavor Trap You Need to Avoid
Here’s a funny thing: people assume dark brown sugar is “brownier.” But it’s not. It’s molassier. That’s totally different. It adds a slight tang and earthiness.
Light brown sugar is more neutral. It’s the basic white T-shirt of sugars. Dark brown is the vintage leather jacket. Both are cool; one just has more attitude.
So, ask yourself: do you want your baked goods to scream “molasses party”? Or do you want a gentle whisper? That’s your deciding question.
