If you’ve been to a Madison-area wedding in the last 30 years and marveled at how truly great the cake was, chances are it was a Carl’s Cake. Since 1985, Carl Loeffel and his crew have been baking wedding cakes that would make you come back for seconds – and thirds. And since 2009, Carl’s Cakes has been part of Market Street Diner and Bakery. A wedding cake is a piece of art. Carl and his staff are artisans.
