Make this magic Tomato Soup Cake! It's based on a classic retro 1950s recipe, with a whole can of soup in it. You can't taste the soup in the moist and fluffy spice layer cake.
I know, you're thinking TOMATO SOUP CAKE???? I was too. And then I tried it...
The results are a super moist, bright orange cake that tastes just like a boxed spice cake. But it's all from scratch.
I've tweaked the original 1950s recipe that was printed on cans a little to make it into a layer cake, rather than a loaf.
If you're going to make a cake with soup, you might as well turn it into a layer cake, right?
You’ll start by making a basic cake recipe with simple ingredients, plus, yup, condensed tomato soup. It's a super easy recipe.
Add homemade cream cheese frosting for a unique cake that’s uncommonly delicious!
If you would have told me that I would have been adding a can of savory condensed tomato soup to a cake recipe, I wouldn’t have believed it!
But after making this cake, I’m glad I did because this cake tastes better than I could have imagined and brings a retro feel to dessert.
Campbell’s soup published this recipe on their cans of condensed tomato soup in the 1940s though it was said to have been around since the 1920s. An eggless version became popular during wartime rationing in WWII.
Believe it or not, the soup doesn’t offer a strong flavor to the mystery cake! Nobody would know it's in there.
However, it does add a beautiful orange-red color and moist texture that pairs well with the warm spices and tangy homemade cream cheese frosting.
It tastes just like a boxed spice cake, and nobody will guess that there's a whole can of condensed tomato soup in there.
Go on, make this magic tomato soup cake. I dare you!

Ingredients & Tools
- Condensed Tomato Soup - The star of this cake, this ingredient makes the cake moist and colors it beautifully. You use the contents of the can as they are (don't dilute with water).
- Baking Soda & Baking Powder - Help the cake rise and become light and fluffy. When you add the baking soda to the soup, it will froth and fizz a bit!
- White Sugar - Gives the cake its sweet taste.
- Unsalted Butter - Adds a rich texture and buttery taste. The soup has salt in it, so be sure to use unsalted butter.
- Eggs - Help bind the ingredients together and set the cake properly.
- Vanilla Extract - Infuses a light sweet vanilla flavor throughout.
- All-Purpose Flour - This is the main dry ingredient that forms the cake batter.
- Cinnamon, Nutmeg & Allspice - The combination of these 3 warming spices give the cake a great comforting flavor.
Cream Cheese Frosting:
- Cream Cheese & Butter - You’ll need both of these ingredients at room temperature to form a creamy, tangy smooth frosting.
- Powdered Sugar - Blends well with the cream cheese and butter, adds structure to the frosting and sweetens it.
- Vanilla Extract - Pairs well with tangy cream cheese and butter.
- Mixing bowl
- Electric mixer - to beat the butter, sugar and eggs
- 2 x 8" (20cm) round cake pans
- Sieve or sifter
Step By Step Tutorial
Follow this step by step photo tutorial, then scroll down to the recipe card for the full ingredients list and method.
Prepare the cake for baking by preheating the oven to 350F/175C. Lightly grease 2 x 8-inch/20cm round cake pans.
Add the condensed tomato soup to a bowl (don't dilute the soup with water) and stir in the baking soda (it will fizz a little). Set aside while prepping the rest of the ingredients.
Beat the sugar and butter together, then beat in the eggs, one at a time until well incorporated, then add the vanilla extract.
Mix in the tomato soup. (Note: it might ‘split’ slightly but don’t worry, it will come together with the flour).
Sift in the flour, baking powder, and spices, then gently mix to combine with a wooden spoon and not the mixer. Don’t overmix, but ensure no streaks of flour remain.
Pour the mixture into the prepared pans and bake for 25 minutes or until an inserted toothpick comes out clean. Cool completely then spread with frosting.
Cream Cheese Frosting:
- Beat the cream cheese and butter together with an electric mixer until smooth.
- Add the powdered sugar and vanilla and beat until smooth.
All refrigerated ingredients need to be at room temperature before baking to ensure even cooking inside the cake.
For this recipe, use unsalted butter as the tomato soup already contains salt.
The cake needs to be completely cooled before frosting to prevent the frosting from melting or running.
You’ll need to make sure you purchase condensed tomato soup only and DO NOT add water. Use the full can undiluted in the cake.
To make sure the cake stays light and fluffy, do not overmix the ingredients. Once you mix the dry ingredients in, use a wooden spoon and fold until there are no flour streaks present without overmixing.
