Honey has a greater sweeting power than sugar. Twelve ounces (Weight) of Honey equals one standard measuring cup. In baked goods, reduce the amount of liquid by 1/4 cup for each cup of honey used; add 1/2 teaspoon of baking soda for each cup of honey used; reduce the oven temperature by 25 degrees to prevent overbrowning. For easy removal spray the measuring cup with non-stick cooking spray or oil before adding honey.
