Got a little bit of time and a jar of molasses? You can fake it. For every 1 cup of light brown sugar, add 1 tablespoon of molasses. Mix it with a fork until it looks like wet sand.
Congratulations. You just made dark brown sugar. It’s almost too easy. You basically become a sugar alchemist right there in your kitchen.
No molasses? Don’t bother. Just use the light brown sugar alone. It’s still better than running out to the store for one bag. Trust me on that.
The Final Verdict (Spoiler: It’s Fine)
Here’s my coffee-talk conclusion: Substitute away, friend. Unless you’re making gingerbread for a Michelin-star chef, nobody will know. And if they do? Offer them a cookie and tell them to lighten up. Pun intended.
Baking is supposed to be fun, not a strict science exam. A little swap here, a little tweak there—that’s how family recipes get invented. Own your choice.
So go ahead. Use that light brown sugar. Your cakes will still rise. Your cookies will still disappear. And you’ll look like a genius who adapted on the fly. You’re welcome.
