Aebeleskiver (Danish) or Poffertjes (Dutch) are traditional cakes, somewhat similar in texture to American pancakes. Aebleskiver are cooked in an Aebleskiver pan, a cast-iron pan with several semi-spherical indentations in the bottom of the pan, giving the cakes their round shape. They are often cooked with bits of apple (Aeble) or applesauce inside. Poffertjes are flatter, are not filled, and the pans they are made in have shallow, non-hemispherical depressions.
