This is a double-decker classic chocolate cake with a fun marshmallow creme center and smooth chocolate frosting, polished off with a mountain of marshmallows and a dusting of cocoa powder. Just like a perfect cup of cozy hot chocolate, this cake is fun and will bring a smile to your face, even on the coldest winter nights.
It’s the middle of winter. The threat of snow lingers on the tip of the newscasters tongue every single morning. The skies have been 95% grey for weeks.
But, winter has it’s bonuses. Hoodies. Right? Snuggling… yeah, I’m starting to like this. Ridiculous cozy socks? Nope, not hot at all, but freakin fluffy! Plaid, layers, scarfs, cute mittens, and all those extra layers to hide any mid winter stocking up you may have needed before the great hibernation of 2015.
Winter may be howling at the front door, but there’s always something comforting and cozy about a steaming mug of hot cocoa with marshmallows rapidly melting into the froth. And this cake is the perfect companion for that chocolaty mug on those cold nights. Besides, we’ve got a few more weeks til we have to buckle down and get those beach bodies ready, right?
For now, let’s just enjoy a few more nights by the fire.
