Chocolate Sheet Cake with Boiled Chocolate Icing

Chocolate Cake with Chocolate Icing

Is it too soon to decide June’s first birthday cake? Even though we’re still six-plus months away, I can’t resist dreaming up confections that our little sweetie will have a ball “smashing” on her big day.

This Chocolate Cake with Chocolate Frosting has been a Chaplin family favorite since The Astronomer’s father’s post-doc days. The recipe originated from a colleague of his named Katy, a gal who clearly had a penchant for unabashedly sweet sweets.

While The Astronomer preferred frosting-less bundt cakes for his birthdays growing up, his brother Daniel and sister Rosalind adored this simple sheet cake. And though I’m 33 years late to the “Katy’s Chocolate Cake” party, I love it all the same.

The batter of the matter, seriously moist and cinnamon-kissed, is finished with a classic, Southern-style boiled chocolate icing. Eaten together, it’s an unstoppable avalanche of buttery, chocolatey, sugary, sprinkle-y goodness!

If June’s palate is anything like her mother’s, this cake will get mauled to pieces in 60 seconds flat. I can’t wait.

  1. This recipe could not come at a better time! Our little guy is turning one next week ^_^ Though we do have a cake ordered for the party I often wondered what cake I can use for him to dig into…That and my phobia of him having a reaction to the ingredients in the dessert (he was a preemie so we’ve been very careful) I’ll make a half recipe this weekend and test out for allergies before the big day. Thanks for the inspiration!!
