Roses say romance, and that's exactly what McCarthy and Wahlberg wanted the cake served at their August 31 wedding celebration near Chicago to convey. Covered with 12 dozen cascading red roses that started at the top and wound their way around, the six-tiered, white buttercream cake was a collaborative effort by the couple and baker Alain Roby of All Chocolate Kitchen. The cake was made with alternating layers of red velvet, vanilla custard creme brûlée and Roby’s famous devil’s food cake (a special request from the couple) . And those amazing roses? They were made of sugar and edible!
