If your muffins or cakes suddenly arenât rising the way they used to, your recipe may not be the problem. Check your baking powder.
Baking powder creates carbon dioxide bubbles when it reacts with moisture and heat, helping batters expand and giving baked goods their lift. But it gradually loses its effectiveness after opening, so an older container can leave you with flatter, denser resultsâeven when youâve followed the recipe perfectly.
⨠Bonus Tip: Not sure yours is still active? Add a small spoonful of baking powder to hot water. Fresh baking powder should immediately fizz and bubble vigorously.
đŹ Question: Be honestâhow long has that container of baking powder been hiding in your pantry? đ
