Instructions

  • Preheat oven to 350 F. Grease and flour a 9-by-13-by-2-inch baking pan.
    Butter and flour or baking spray
  • In a large bowl, combine the flour, baking soda, cinnamon, ground allspice, nutmeg, and ground cloves; set aside.
    4 cups all-purpose flour | 1 1/2 tsp baking soda | 2 tsp ground cinnamon | 1/2 tsp ground allspice | 1/2 tsp ground nutmeg | 1/4 tsp ground cloves
  • In a large mixing bowl with an electric mixer, beat the butter until light. Beat in the brown sugar until the mixture is light and fluffy. Add the eggs and vanilla, and continue beating until well blended.
    1 cup unsalted butter | 2 cups brown sugar | 2 large eggs | 1 1/2 tsp vanilla extract
  • Pour the tomato soup into a 2-cup measure; add enough water to measure the full 2 cups.
    1 (10.5 ounce) can condensed tomato soup
  • With the mixer on low speed, add the flour mixture to butter and egg mixture (about one-third at a time) alternating with tomato soup mixture and ending with flour mixture. Beat just until combined.
  • Fold in the chopped nuts and raisins or dates and then spread in the prepared baking pan.
    2 cups chopped walnuts or pecans | 1 cup raisins or chopped dates
  • Bake for 55 to 60 minutes, or until the cake tests done. A toothpick should come out clean when inserted into the center of the cake.
  • Cool the cake in the pan on a rack for about 30 minutes. Leave it in the pan to cool completely or turn the cake out of the pan onto a rack.
  • Frost the tomato soup cake with cream cheese frosting or your favorite icing, or simply sprinkle it with powdered sugar.
