I recommend using 8 ounce mason jars, because they are great for individual serving sizes - but this can be flexible. If you don’t have the recommended size, you can use any size mason jars for your cakes - or you can even use a regular glass cake pan if you wish. Using an oven-safe glass bowl or pan will create more of a tie-dye or swirly effect.

My suggestion is to use 8 of the 8 oz jars, or 4 of the 16 oz jars. You can also mix and match or use other oven safe glass.
