Grandma Sula’s Peanut Butter Cake

I made my great-grandma’s peanut butter cake for work today.  Something is a little off in the recipe I was given, and I always end up improvising.  I decided to actually record what I think I did last night so I can repeat it!  The cake turned out delicious.  It was mostly gone before 9:30 this morning.  The powdered sugar heart was added at the last minute to make it holiday appropriate.


Cake Ingredients:

  • 3 cups of flour
  • 1/2 cup of creamy peanut butter
  • 2 cups of milk
  • 2 teaspoons of apple cider vinegar
  • 2 teaspoons of baking soda
  • 2 cups of white sugar
  • 1/2 cup of butter
  • 2 eggs, beaten

Icing Ingredients:

  • 2 1/2 cups of powdered sugar
  • 3 tablespoons of butter
  • 6 tablespoons of coffee
  • 1/4 cup of peanut butter


  • Preheat the oven to 350 degrees Fahrenheit
  • Grease a 9 by 13 inch pan
  • Cream white sugar, 1/2 cup of butter, and 1/2 cup of peanut butter
  • Beat in eggs
  • Sift flour and baking soda in another bowl
  • Mix the milk and apple cider vinegar in a liquid measuring cup
  • Add the flour mixture to the first mixture alternating with milk
  • Pour batter into pan and bake 40-45 minutes or until a toothpick comes out of the center of the cake clean; the cake should be a dark golden brown
  • Allow the cake to cool
  • Using an electric mixer, mix the powdered sugar, remaining butter (melted), peanut butter, and coffee.  You may want to adjust the ingredients for taste or consistency.  Adding more sugar will make the icing thicker.  Adding more butter and coffee will turn the icing into more of a glaze.
  • Ice the cake
