Bundt cakes are cakes baked in a Bundt pan - their characterising feature is their shape. A Bundt pan has fluted or grooved sides, but its most defining design element is the central tube or "chimney" which leaves a cylindrical hole through the centre of the cake. The design means that more of the mixture touches the surface of the pan than in a simple round pan, helping to provide faster and more even heat distribution during baking. The ring feature in Bundt cakes means they tend to have more of a crusty edge than a normal cake, with a moist centre.
