Question: what is a cake of yeast?
Answer: cake is equal to 1 packet (2+1/4 teaspoons) of dry yeast. Divide a 2 oz. cake into 3 equal parts, where each part is equal to 1/3 of the cake. See Yeast Conversion Table to convert between Cake Yeast and Dry Yeast, or to determine your yeast requirements for your recipe.
