Cream the lard and margarine about 12 minutes. Add brown sugar, salt and continue beating seven to 15 minutes more until light and fluffy.
Add flour and mix until crumbly. Weigh out 14 ounces of this mixture and pat this flat on the bottom of a greased 9x13 cake pan.
Combine water and soda and add to molasses. Pour in 1 ⅓ cups of molasses mixture.
Sprinkle half of the remaining crumbs over this, pour in the rest of the molasses mixture and sprinkle the last of the crumbs on top.
Bake at 350° for 30 to 35 minutes. Cut the cake into 15 servings. Top with the Whipped Cheese Topping and Lemon Sauce.
Whipped Cheese Topping
Beat cream cheese and coffee cream together until creamy. Put about a tablespoon on top of each cake serving and pour warm lemon sauce on top.
Lemon Sauce
Mix dry ingredients together. Bring water to boil and then slowly add dry ingredients. Cook for about 15 minutes. Then add egg yolks, lemon juice, rind and butter. Stir until well mixed. Remove from heat and serve warm.
