how much truvia in a cup of sugar
General rule of thumb is 1 cup of sugar = 1 teaspoon liquid stevia or one-half teaspoon of the stevia extract powder. If you are using a stevia product like Truvia or Purevia, it's 1 cup sugar to 12 teaspoons Truvia or Purevia. To make it function like sugar however, in the way we're used to, you need to bulk up the stevia. You're using less volume so you need to make up for it. So let's say you are making banana bread.
