1/2 c. buttermilk
2 eggs, well beaten
2 c. sugar
2 c. flour
1 tsp. baking soda

Over medium heat, mix the first 5 ingredients. Stir until very well mixed and thoroughly heated. Remove from heat. Add the last 4 ingredients and stir until mixed well. Bake in a lightly greased jellyroll pan at 350 degrees for 25 minutes.

When cool, spread the top with a small (8 to 12 ounce) jar of peanut butter that has been mixed with 1 tablespoon cooking oil. Over medium heat, bring to a boil:
