Step 1: Ingredients
So find your favorite cake mix and supporting ingredients, or make it from scratch. The best part about making your own is that you can make half of one kind and half of another!
You'll also need a bunch of canning jars - straight sides, wide mouthed. I got the wee-est ones I could find for cuteness' sake. You can definitely make them in bigger jars.
Boil or wash the jars to sterilize them. You'll want brand-spanking-new lids to make a tight seal when you're done.
The box mix made enough batter to fill 16-20 jars!
Step 2: Make Cake Batter
Or look here for some inspiration to make your own!
Fill the jars about half-way with batter. If you fill them too full, you can always squish them down, or cut the tops off. But too much batter will result in them flowing over the sides of the jars.
Place in a baking dish for ease of handling.
