Before ovens, direct sunlight was needed to bake cake batter, ruining the birthday dreams of countless bats. Enjoy baked treats in your darkened domicile with today's Groupon: for $10, you get $20 worth of baked goods and a waived pickup fee from Piece of Cake by Valerie Herrera on Raton Drive. This Groupon cannot be used to pay for delivery.

Valerie Herrera, a skillful cake manipulator and civil engineer, builds humble egg and flour foundations into towering dessert structures. The light texture of vanilla tres leches cakes ($20) wins over pitchfork-toting tongue mobs outraged at its unnatural fusion of three milk types, and strawberries doused in chocolate and dusted with sprinkles ($20 a dozen) tempt even even-tempered palates. Batches of nine walnut-infused brownies ($7.58) and batches of 24 carrot cupcakes ($21.65) prove desirable additions to any permanent dessert collection.

Free flavor consultations teach cake commissioners which fillings and frostings to favor when designing the multilayer custom desserts ($0.75–$1 per serving) that will grace their divorce receptions. Patrons should give 48 hours' notice for custom cakes.
