How To Make Brown Sugar

When I made this peanut butter cookie the other night, I realized I was out of brown sugar but that was totally okay.

I made my own brown sugar and it's so easy to do. All you need to make brown sugar is granulated sugar and molasses.

Here's how:

Mix together two tablespoons of granulated sugar and 1/4 teaspoon of molasses with a fork and voila, the perfect amount of brown sugar for this peanut butter cookie recipe.

If you need to make a larger batch of brown sugar, mix together 1 cup of brown sugar and 1 tablespoon of molasses.  No quick run to the grocery is needed.


For this peanut butter cookie I use an 8.5-ounce ramekin. For best results, use a baking dish of similar size.

Pro Tip: Many ramekins don’t have the size printed on them. Because of this, it can be hard to know exactly how large (or small) yours is. The best way to measure the size of your ramekin is to fill it with water and pour the water into a measuring cup.

  1. Hi Joanie
    This recipe calls for 3 tablespoons of peanut butter. I use peanut butter powder.
    Is the exchange the same: one for one?

    1. Hi Carol, I haven’t tested this recipe with peanut butter powder so I’m not sure how much you would need to use. I believe the powder will have to be reconstituted with water before using.

    This was great! However, I’m not sure if something went wrong or if the texture is supposed to be that way, but after cooking it for 10 minutes, the cookie had a strange dough-y texture to it. It was cooked, though, so I ate it. The taste was delicious, I just wasn’t a big fan of the texture! 🙂
