Honestly, Peeps, I could not be more excited about sharing this chocolate sheet cake recipe with you, as it includes two of my favorites: chocolate cake and marshmallow-like frosting (there’s a reason I loved Hostess Suzy-Qs as a kid and some things just never change). The chocolate sheet cake is essentially one-bowl (my fave) and the marshmallow frosting, too, is super easy and one-bowl(ish), save for the strawberry puree that you throw together in a blender.
This cake came to be (tho in cupcake form) several years ago on the occasion of my younger son’s 10th bday. He requested strawberry frosted chocolate cake, and rather than make a strawberry-flavored American buttercream (my go-to and first true love), I went in the seven-minute direction and could not have been more pleased with the results. I cannot tell you if the bday party guests, or even the bday boy himself, enjoyed it, as they were too busy shooting each other with paintball guns to take the time to analyze and deliver feedback (and, yes, you’re right: paintball with twenty 10 year olds in the wilds of New Jersey was an extremely bad idea).
Cut to today, when I am sharing with you a modified version of the now infamous bday paintball cupcakes. The cups have morphed into a cake, of the sheet variety, and have been one-bowl-ified. The frosting is a tad more streamlined as well. And – you guessed it – I am sharing it just in time for Valentine’s Day, as the frosting quite literally screams the mid-February holiday we all love (or love to hate). 
It is worth noting that I developed the recipe for food52, as it will accompany an article of mine they will be publishing towards the middle of the month (it’s all about loosening up in the kitchen when feeding kids). The kind folks at food52, however, were willing to feature the recipe on their site prior to the article running and in time for V-Day, for which I am very grateful (and hope you are too). The recipe can be found on food52, here.
