When you want to reduce the fat content and improve the nutritional value in your cake, cookie, muffin or brownie recipe, substitute yogurt for the vegetable oil. While many cooks use applesauce as an oil substitute in baking recipes, it requires the baker to adjust the sugar amounts to compensate for the sweetness added by the applesauce. When using yogurt instead of oil, you don't need to adjust the sugar amounts to make the substitution.
Drain the excess liquid off the top of the yogurt. When you open a carton of yogurt, there is usually watering substance floating on the top of the yogurt, which is what you drain off. Your carton of yogurt might not need to be drained.
Read the recipe to determine how much oil it calls for.
Measure out yogurt as you would oil. For example, if the recipe calls for 1/4 cup of oil, measure out 1/4 cup of yogurt instead.
Add the yogurt to the recipe as if you were adding oil. Follow the rest of the recipe.
