Into a small-medium sized saucepan, add the sugar, water, cocoa powder and salt. Use a whisk to combine. If all the cocoa powder doesn’t mix in right away don’t worry because it will as it cooks.

Place your saucepan over medium heat and cook until just starting to bubble. Make sure to stir frequently with a whisk. Once it bubbles it’s done.

Remove the syrup from the heat and stir in vanilla. Store in a glass jar or container and place in the fridge. Or you can keep it on the counter for up to a week.
