Tomato Soup Cake

At first glance, “tomato soup cake” might sound like a prank your grandma would play—but this Depression-era gem has been winning over skeptics for almost 100 years. The original versions started popping up in the 1920s and 1930s, when thrifty cooks leaned on pantry staples like canned soup to make something sweet and satisfying. Campbell’s led this trend, printing versions in their cookbooks for decades and even on the sides of soup cans.

This version of tomato soup cake is baked up in one pan—making it a no-nonsense dessert. And here’s the best part: it doesn’t taste like soup. Promise. What you get is a tender, spice cake (thank you, pumpkin pie spice) with a subtle tang that keeps it from being too sweet. In other words, it’s a cousin to applesauce cake and gingerbread cake —unexpected, a little nostalgic, and totally delicious.

A swoopy layer of cream cheese frosting seals the deal, making this cake look as cozy as it tastes. Slice it big for an after-school snack, bring it as a potluck dessert, or serve it at Sunday dinner just for the conversation starter. One bite, and you’ll see why this oddball recipe has stuck around for nearly a century.

Why put tomato soup in a cake?

It might sound unusual, but the tomato soup is actually doing some heavy lifting in this recipe for tomato soup cake. First, its acidity reacts with the baking soda to help the cake rise. It also contains thickeners and emulsifiers, which lock in moisture so the cake stays tender. On top of that, it adds a subtle tang that deepens the spice flavor, and even gives the cake a warm, rosy hue. Think of it less like soup and more like another fruit purée—similar to applesauce or mashed bananas in quick breads.

Does tomato soup cake taste like tomatoes?

Not at all! The tomato soup doesn’t make the cake savory—it simply enhances the spice flavors and gives the cake a great texture. What you’ll taste is a warmly spiced cake with hints of cinnamon and clove. If you didn’t know the secret ingredient, you’d never guess it was there—it just tastes like a really good spice cake.
