grapefruit-cupcakes My replacement kitchen aid arrived yesterday and I was eager to use it again. I made walnut raisin bread and these cupcakes for a picnic tomorrow. The cake is a slight variation on the white butter cake by Levy-Beranbaum. I added grapefruit zest. The frosting is orange zest and cream cheese. I'll leave a few out for when Chris and Kate come back late at night.
