I made this recipe some years back. I could swear this recipe called for heavy cream. Am I correct?

Kimberly - the ingredient list doesn't call for heavy cream (whipped), but reading through the instructions I saw an option to use it as garnish. Is that what you are remembering?

I checked the Wayback Machine for when the recipe was first published in 2013 and it seems to be identical: https://web.archive.org/web/20130223094508/https://food52.com/recipes/4185-aunt-mariah-s-lemon-sponge-cups
