This delectable cake can be made as a sheet cake with a fudge-like frosting poured over it, as a round layer cake with frosting sandwiched between each layer, or as incredible cupcakes—which you can either dip into the warm, thick chocolate fudge frosting or top with the whipped frosting smoothed over like a traditional buttercream.

The Story Behind This Einkorn Sourdough Chocolate Cake

The inspiration for this recipe comes from my own childhood. This is a cake my mom would make for special occasions. Of course, I had to modify the recipe to include unrefined coconut sugar, sourdough starter, and a more digestible, more tender einkorn flour.

This is one of my daughter’s favorite cakes, so I make it for her birthday. I’ve tried to make the cake itself a little more healthy, but there’s not really anything I can do about the frosting. It’s just loaded with sugar! Definitely a once-a-year treat.
