1 (2 oz.) box poppy seeds
1 box white cake mix (or your own recipe)
1 box (3 1/2 oz.) vanilla or lemon pudding mix (not instant)

Soak poppy seeds 1 hour in 1 cup water or milk. Which you plan to use in the cake. Make cake as directed, using the poppy seed mixture for part of the liquid. Use layer pans. Make the pudding, using 1/4 cup less liquid to make it stiffer for the filling. Cool and spread between layers.

Frost with white icing, use your own butter recipe, or for a lemon flavor, try 1 1/2 cups powdered sugar and 2 tablespoons lemon juice.
