Notes
Gluten-free adaptationWhile it can be hard to find gluten-free spice cake mix, gluten-free yellow cake mix can be used to make homemade spice cake mix and is available in most grocery stores. Be sure to look at the note below about the weight of cake mix boxes and factor that into how much equivalent homemade mix you will need.You will be replacing the spice cake mix, the flour, and the baking soda with the equivalent of 18.25 ounces of homemade spice cake mix. Adapting this recipe to use the homemade cake mix will require the use of a kitchen scale to ensure that the homemade cake mix is 18.25 ounces.Cake mix sizes When this recipe was developed, cake mixes were a standard 18.25 ounces per box. These days, they have shrunk to around 16 ounces or even 15 ounces. To make up the difference in weight between the 18.25 ounce box the recipe originally called for and today's smaller box, we have added flour (½ cup + 3 tablespoons) and baking powder (½ teaspoon) to be sure the ratio of solid to liquid stays the same.If your spice cake mix box is a size other than 15.25 ounces, you can calculate how much flour to add using this cake mix calculator. Most of the mixes available in my area are 15.25 ounces, so the recipe has been adapted to that size mix. If your mix is different, OMIT the flour and baking powder in the recipe and use the calculator to figure out how much flour and baking powder you need to add for the difference between and an 18-ounce mix and the size mix you have.
