Notes
Nutrition information is provided as an estimate only and will vary based on the exact ingredients used and serving size.Note about cake mix: When buying a cake mix, look for the standard 15.25 ounce size. Some brands have scaled back the box cake mixes to 13.25 ounces and this throws off the ratio, making a batter that is too runny.
