We used 2.5 ounce shot glasses for this recipe. You can easily make these shots in smaller shot glasses if desired. These 2 oz shot glasses that come with disposable lids are a popular option and would work well for these candy corn jello shots. If you use glasses or cups smaller than 2.5 ounces as we used, you will get even more shots out of this recipe, so keep that in mind for how many cups you may need!
