Here is the recipe, I kept track of the amounts.
Poppy seed cake.
Ingredients for dough bottom.
2 sticks of butter
2 whole eggs plus 2 egg yolks, ( save egg-whites)
! cup sugar
1 TBsp Baking powder
2 ½ cups All-purpose flour
Ingredients for topping
1 can Solo Poppy Seed cake and pastry filling
2 egg-whites from above saved
1 Tsp Baking powder
½ cup flour
Procedure.
Melt butter, and let cool to about 90°F, Don't want butter if hotter
to start cooking eggs when added.
Place eggs into stand mixer, add sugar, and mix well
Add butter, and Baking powder, and mix.
Add 2 cups of flour, and mix with dough hook until smooth.
Remaining ½ cup of flour, add spoon at a time until desired consistency
reached. May not be needed if the eggs were smaller than usual.
Pan (parchment lined) spray with Spray Butter, and spread dough on bottom
Make topping ; first beat the egg-whites. Add contents of poppy seed can.
Add 1 Tsp baking powder, and mix well. mixture will be somewhat loose,
so add ½ cup of flour, and mix well. Topping will not be as stiff as bottom dough layer.
Spread on top of dough,, Preheat oven to 350°F.... Bake 45 minutes
Check with toothpick inserted in middle. If comes out dry, cake is baked.
Let cool in pan for about 15 minutes, so when taking out, it will not fracture.
On a flat cutting board, slice, and consume warm, or wait if you can and consume cold.
Notes:
Pan used,, 9 inch by 12 inch 2 inch deep
Butter can be replaced with margarine
Cake will be somewhat firm rather than moist. Texture similar to Pound Cake.
Can reduce flour amount in dough to get less firm, and more moist texture.
Spray Butter can be omitted with greased pan with regular butter.
