This tomato soup cake is a sweet spice cake. Yes, tomato soup is an odd ingredient for a cake — but this cake tastes yummy. Once the cake has cooled, you can top it with cream cheese frosting if you like. People will never guess what the main ingredient is.
For optimal results, ensure all cold ingredients like butter and egg are at room temperature to create a smooth, emulsified batter. Avoid overmixing the flour once added; mix just until combined to maintain a tender crumb. While tomato soup is the base, its primary role is to provide moisture and a subtle tang that complements the warm spices. Consider toasting your ground cinnamon and cloves lightly before adding to deepen their aromatic profile. Plump raisins in warm water or a tablespoon of rum for a juicier texture. A generous layer of classic cream cheese frosting is highly recommended to balance the spice and complete the traditional flavor profile of this unique cake.
