This gorgeous cake needs no frosting in my opinion, as it offers plenty of sweet, sweet, goodness all by it’s lonesome. Plus, served undressed is the best way to show off its striking swirls.
When marbling the batter, be sure to go the whole width of the cake to get the deepest variegation of contrast between the yellow and chocolate swirls. And don’t overdo it! A little swirl goes a long way, and too much will muddy the pattern.
