Kansas City-based Interstate Bakeries Corporation (IBC) is voluntarily recalling all Drake's Sunny Doodles snack cakes marked with "best before dates" or "sell by dates" of 22 July through 2 August. During a routine review of product formulation, it was discovered that the soy flour used in Sunny Doodles was not listed on the packages' ingredient legend. No other Drake's cakes are affected by this recall.
