Chocolate Buttermilk Cupcakes. Love this recipe, which comes straight from the Magnolia Bakery cookbook. The cupcakes turned out light, moist and tender. The chocolate flavor was spot on - I actually liked that they were not too sweet. These cupcakes were made in next to no time. The batter made 28 cupcakes, which I baked for 23 minutes at 350F. The icing, a simple whipped chocolate ganache, made frosting the cakes so easy. I actually made these cupcakes again last night, using a simple cream cheese/butter/heavy cream/vanilla bean frosting. Everyone at work liked them. This recipe is a keeper. 10/10. RUTH YEAMAN.
