Coffee Custard Filling for Jelly Roll

Coffee Filling for Jelly Roll
Coffee Filling for Jelly Roll is a classic cooked custard-style filling that brings rich, aromatic flavor to delicate sponge cakes. Popular in mid-20th century American baking, jelly rolls were often paired with smooth vanilla or chocolate fillings, but coffee versions added a sophisticated touch. This filling blends scalded milk infused with ground coffee, eggs, sugar, and flour to create a thick, silky custard. Cooked gently and stirred constantly, it transforms into a luscious spread that complements the light texture of a rolled sponge cake, offering a subtle bitterness balanced by sweetness and vanilla warmth.
