Grandma made a “Secret” cake whose main ingredient was…canned tomato soup!

Grandma’s “Mystery Cake” looked like this!

TOMATO SOUP MYSTERY CAKE RECIPE

4 Tablespoons unsalted butter, softened
1 cup granulated sugar
1 large egg, well beaten
1 can condensed tomato soup (Campbell’s preferred) 10 3/4 ounce size
1 teaspoon baking soda
1 1/2 cups Unbleached All-Purpose Flour
1/2 teaspoon baking powder
1 scant teaspoon ground cloves
1 teaspoon cinnamon
1/2 cup raisins, optional
INSTRUCTIONS
Preheat oven to 350°F. Spritz a 9” round cake pan with cooking spray. Line with a parchment circle and spritz with spray again. Cream butter and sugar in large bowl. Add egg and mix well.
Combine baking soda with undiluted soup in can. Let foam for 1 minute. Pour soup mixture into butter/sugar/egg and blend well. Mixture will look slightly curdled. This is normal.
In a small bowl combine flour, baking powder and spices. Whisk well and add to tomato soup mixture. Beat together for 1 minute on medium speed. Pour into prepared pan and bake for 30-35 minutes. Cool on wire rack and ice as desired.
