History
Custard desserts have been enjoyed for centuries throughout Europe. Traditional custard, made from milk, eggs, and sugar, dates back to medieval kitchens where it was used in pies, pastries, and puddings. Over time, bakers began combining soft sponge cakes with creamy custard fillings to create elegant layered desserts.
Chocolate sponge cakes became popular in the 19th century after cocoa became widely available. The marriage of chocolate sponge and vanilla custard soon became a classic combination because the slight bitterness of cocoa perfectly complements the sweet, silky custard.
Today, custard layer cakes are found in bakeries around the world and remain a favorite for celebrations because of their beautiful presentation and comforting flavor.
