How to make vanilla sugar
Vanilla sugar is just regular sugar that’s flavored with vanilla beans, so you can use it in any recipe that calls for sugar for a little extra boost of flavor. You don’t need a specific recipe, just some granulated sugar and vanilla beans (I love to use leftover vanilla beans from other recipes!)
Place the vanilla in a small jar or other container, cover with granulated sugar, and let them sit for a week or longer. The more vanilla beans you have in your sugar, the stronger the flavor.
