Whether or not you watched the Chicago-set Hulu show where this cake made its debut, you’ve probably seen it before — perhaps on Instagram or magazine covers. Sarah Mispagel-Lustbader’s striking cake is backed up by deliciousness and pure indulgence: three layers of chocolate sponge with frosting between, and a finish of rich ganache. $7.50. 2934 N. Milwaukee Ave., Avondale
