Love is in the air in The Kitchen with Valentine's Day food, crafts and sweet surprises. Katie Lee makes a trendy Hidden Heart Cake, and then the gang creates food-inspired Valentines for sweethearts of all ages. Jeff Mauro's Snack Mix Brownies and Sunny Anderson's Sour Cream Swirl Brownies use mix-ins to put a new twist on the favorite dessert, and everyone pitches in to create a Box of Chocolates Cake. Geoffrey Zakarian serves Pasta Pomodoro as a dinner for two, and comedian and author Mamrie Hart stops by to join in on the fun with her French Kiss 75 cocktail and a serving idea for nachos.
