Classic White Cake and Buttercream Frosting

By srumbel

With all the chocolate lovers in our house, I know it's hard to believe, but my husband is not a fan of chocolate. I always make something special for him during the holidays. Classic White Cake with Buttercream Frosting is his favorite holiday dessert. I made it for him last Thanksgiving. I am making another one this year for Thanksgiving. I thought you might like to make one too.
