Your celebration is very important and Costeaux pastry chefs take great pride in making the best cakes for any occasion. Costeaux signature cakes are available year round and are a go-to for Costeaux guests. These cakes and seasonal offers are handcrafted and available in six and 8-inch sizes. Due to the nature of a cake designed and decorated by hand, designs may slightly differ.

Serving Sizes
Signature cakes are four delectable layers of cake and filling. Generally, a 6-inch cake serves 8-14 people and an 8-inch serves 16-26 people.

Enjoy Costeaux Cakes at Their Peak
Desserts often taste best when served at room temperature. Set cake out 1-2 hours prior to serving. Whipped cream finished cakes should be served slightly below room temperature. When cutting, use a hot knife blade that makes for clean slices.  Run the knife under water or dip into a hot water wiping the blade clean between cuts.
