This is the cake people called “mystery cake.” A can of condensed tomato soup goes right into the batter. You don’t taste tomato at all. The soup adds moisture and a little tang, and the cinnamon, allspice and cloves take over. It’s a soft, old-fashioned spice cake, and it’s even better with cream cheese frosting.

A little history

Tomato soup cake goes back to the 1920s and 1930s, when cooks stretched what they had. The recipe was later printed on soup cans and in magazines and church cookbooks for decades. It stayed popular because it’s cheap, easy and always moist.

Tips

  • Use condensed soup, straight from the can. Don’t add water to it.
  • Don’t overbake. Start checking at 30 minutes. A toothpick in the center should come out clean.
  • Let it cool completely before frosting.
  • Add 1/2 cup raisins or chopped walnuts to the batter if you like.

Storing

Keep the frosted cake covered in the fridge for up to 4 days. Bring slices to room temperature before serving.
