Pumpkin-Chocolate Swirl Cupcakes With Chocolate Buttercream
If you’ve never had pumpkin and chocolate together before you’re in for a real treat. These cupcakes stay moist and tender not only due to the pumpkin puree but thanks to the addition of sour cream in the batter. And don’t be intimidated by that pretty swirl; all it takes is a toothpick or a narrow paring knife to marble the pumpkin and chocolate batters together. The frosting is a riff on one or our all-time favorite, super-simple cream cheese frosting recipes. The cream cheese offers just the right tang to offset the sweetness and richness of the chocolate.
