Question: is baking powder low carb?
Answer: Baking powder, on the other hand, does contain carbs, since it often contains corn starch. But you don't have to worry too much. Baking powder only contains about 1.3 grams of carbs per teaspoon, so as long as you're not loading up your batter with spoonfuls of baking powder, it should be okay to use it in your baking.
