The Snickerdoodle Scenario
If you’re making cookies, brownies, or any baked good that’s already a flavor bomb (chocolate, spices, fruit), go ahead and swap without a second thought. Use a 1:1 ratio—one cup of dark for one cup of light. The extra molasses won’t mess things up.
In fact, dark brown sugar will add a little extra chewiness to cookies. That’s a win! Your friends will think you’re a baking genius, and you can just nod mysteriously.
The Muffin & Crumble Zone
For quick breads, muffins, or fruit crisps, dark brown sugar is actually a secret weapon. It makes the top crust darker and shinier. Your banana bread will look like it was kissed by a caramel fairy.
Pro tip: If you use dark sugar in a light-colored cake (like a white velvet), the cake will be slightly beige. Gasp! It won’t taste bad, but your aesthetic-loving friends might raise an eyebrow.
