A mixing paddle for mixing dough and for cutting and mixing dense ingredients such as butter and shortening into dry ingredients such as flour has roughened cutting blades oriented at many angles. Some blades are attached between a central blade support shaft and a symmetrical rim. Blades near the apex of the rim rotate in concentric double cone paths. The blades may have roughed cutting edges to increase variety in fat chunk size and to improve mixing.
