The cake I did for my husband's (and my own) birthday this year; it was a Fiesta theme party. 2-layer, 9x13 French Vanilla Cake with Dulce de Leche filling and vanilla buttercream (including piped cacti). MMF chili peppers, streamers and covered sombrero (made with Wilton Mini-Wonder Mold). Margarita candles are the only purchased, non-edible decor. This cake was fantastic (SO yummy) and I got a lot of compliments on the decorating.
