With all the festive desserts in creation, petit fours — those teensy cakes you'd plate for all your creepiest dolls at a tea party — are among the most jubilant a person can serve.

Sink your teeth into a croissant from the new Le Petit Four Bakery. When the crispy exterior shatters into delicate bits, the taste of the buttery layers inside, thin as tissue, is pure bliss.
