A Bundt cake is a cake that is baked in a Bundt pan, shaping it into a distinctive donut shape. The shape is inspired by a traditional European cake known as Gugelhupf, but Bundt cakes are not generally associated with any single recipe. The style of mold in North America was popularized in the 1950s and 1960s, after cookware manufacturer Nordic Ware trademarked the name "Bundt" and began producing Bundt pans from cast aluminum. Publicity from Pillsbury saw the cakes gain widespread popularity.

Cake is a flour confection made from flour, sugar, and other ingredients and is usually baked. In their oldest forms, cakes were modifications of bread, but cakes now cover a wide range of preparations that can be simple or elaborate and which share features with desserts such as pastries, meringues, custards, and pies.
