Carrot Cake with Caramel Buttercream - What a perfect Easter dessert! This carrot cake recipe is so moist and tender. It's made with vegetable oil instead of butter. It's spiced up with some cinnamon and nutmeg too. The frosting is a swiss meringue buttercream with a caramel sauce added to it. Plus, sandwiched between each cake layer is even more caramel!
