Making a jar of cake-mix "upsizer"

As we've discussed before here on the blog, it's getting difficult to find a cake mix that hasn't been reduced from 18.25 ounces to 15.25 ounces. This week, two things came up that made me want to work on a solution of sorts to this issue.

First, I wanted to make my favorite lemon streusel recipe, which uses a lemon cake mix as a base.

Second, my beautiful mom gave me a new cookbook for Christmas, Taste of Home's "Fast Fixes With Mixes," which uses...

...18.25-ounce cake mixes as bases for other recipes.

In light of both of these, I wanted to figure out a way to add three ounces back in to a boxed cake mix so that these recipes would bake up the same as they previously had. I had the idea to mix it up, store it in a mason jar, and then just spoon out a few tablespoons-full of mix extender when I needed it. Here's what I came up with:

Three-Ounce Cake Mix "Upsizer"
Adapted from the Better Homes & Gardens New Cook Book white and yellow cake recipes:

1 1/2 cups all-purpose flour
1 cup sugar
2 teaspoons baking powder
1/4 teaspoon baking soda

Whisk all dry ingredients together and store in a clean mason jar. When you wish to increase a 15.25 ounce cake mix to 18.25 ounces, add three ounces of this mix (6 tablespoons) to your existing cake mix.

I'm using this now to upsize cake mixes for any recipe that uses a cake mix as an ingredient, as those recipes are based on the older, larger-sized mixes. And that lemon streusel that I love? Came out perfectly!


Other ingredients?

If you start with a new, lesser quantity, mix and add the ounces back in, do you need to increase the liquid (oil, water, egg) shown on the back of the new box? I don't have a new box in my cupboard right now to compare the extra ingredients required to what was required for the old box. So, I don't know if they also decreased the required liquids and now that we can add back in more dry ingredients (thanks to your recipe), will that throw off the batter consistency?

Strangely, no

The differences in the liquid between the old and the new are minimal - less than 1/4 cup if I remember correctly. I've never adjusted the liquid when using the upsizer.

Consider that the new formulations seem to be designed to hold more air in the batter. The companies claim that the cake will still fill the same volume of pan, despite having three ounces less mix. That seems to go against all the laws of physics unless you consider that volume was "recaptured" by having more air bake up into the mix.

Great idea!

I'm planning to try this tonight. I need to make cakes for my son's birthday, and when I read the side of the cake mix box, I noticed it only makes 10 servings! The older boxes I have make 12. Grrrr!!!

Crazy, isn't it?

I can tell you this works well though. Since making the lemon cakes at Christmas, I've also made two birthday cakes, and I just add the 6 tablespoons to a boxed mix. So far, I've used it on a yellow cake and a strawberry cake with no issues (and MORE cake :)

Thanks!

I knew things were getting downsized to keep from raising prices, but I never thought about the cake mix as an ingredient. I just used a box of cake mix as is. Might explain why the recipes came out extra moist this year. LOL. They were still good though. ;)

This is a good idea. I will make some up this weekend. Good to have on hand

CLEVER IDEA

To have on hand for problems like a sized down box of cake mix. Never noticed since I don't bake much anymore. I know everything is getting sized down lately !
