Ingredients
  

Cake

  • 1 cup brown sugar
  • ⅔ cup butter
  • 3 eggs
  • 1 tsp cloves
  • 1 tsp allspice
  • 1 tsp cinnamon
  • 1 tsp nutmeg
  • 1 tsp baking soda (dissolved in sour milk)
  • tbsp sour milk ( or buttermilk)
  • 1 ½ cups flour
  • tsp baking powder
  • 1 cup sweetened stewed prunes (mashed)

Filling

  • 1 egg (beaten well)
  • ½ cup sugar
  • 2 tbsp butter (size of an egg)
  • ⅓ cups sour cream
  • ½ cup raisins
  • ½ cup nuts (chopped )

Instructions
 

Step 1: Prepare the Prunes

  • Cook prunes until tender, drain, and mash. Measure 1 cup and set aside.

Step 2: Make the Cake Batter

  • Cream together brown sugar and butter until light and fluffy.
  • Beat in eggs one at a time.

Step 3: Add Spices & Dairy

  • Mix in cloves, allspice, cinnamon, and nutmeg.
  • Add baking soda dissolved in sour milk.

Step 4: Fold in Flour

  • Sift flour with baking powder.
  • Gradually add to batter, mixing until smooth.

Step 5: Add Prunes

  • Stir mashed prunes into the batter until evenly combined.

Step 6: Bake the Cake

  • Pour batter into greased, floured cake pans.
  • Bake at 350°F (175°C) for 40–50 minutes, or until a toothpick comes out clean.
  • Cool completely before filling.

Step 7: Make the Filling

  • In a saucepan, combine egg, sugar, butter, sour cream, and raisins.
  • Cook over medium heat, stirring constantly, until mixture begins to thicken.
  • Remove from heat and stir in chopped nuts.

Step 8: Assemble the Cake

  • Spread filling between cake layers and on top.
  • Let set before slicing.

Tips

  • Use pitted prunes and stew gently in water or juice until very soft before measuring.
  • If “butter the size of an egg” is unclear, use about 3 tablespoons of butter as a practical substitute.
  • Add toasted chopped nuts to both filling and topping for extra texture.
  • If desired, add vanilla extract (½ to 1 teaspoon) to the filling for flavor depth.
  • Bake batter in two round pans for easy layering; cool completely before filling.
  • Lightly dust layers with cinnamon sugar before adding filling for enhanced spice.
  • Replace raisins in the filling with chopped prunes if you prefer a uniform fruit filling.
  • Add a light glaze or whipped cream topping for special occasions.
  • For a slightly tangier filling, use full-fat sour cream as written.
