Frequently Asked Questions
Does the tomato soup cake taste like tomato?
No. The soup adds moisture and a touch of tang, but the spices completely cover the tomato flavor. Most eaters never guess.
Is the butternut squash mac and cheese kid-approved?
Yes. The squash blends seamlessly with the cheese, and most kids cannot tell. Texture is identical to regular mac and cheese.
Can I substitute frozen blueberries?
Yes. Use directly from frozen; no need to thaw. The cooking time is the same.
Why use secret ingredients?
Three reasons: hidden moisture (tomato soup, applesauce), hidden nutrition (squash, spinach, beans), and creative flavor depth (chocolate in chili, coffee in chocolate cake).
Can I make these vegetarian?
Two of three are already vegetarian. The chicken recipe substitutes well with seared tofu or roasted cauliflower for a vegetarian version.

Can you please tell the size of the tomato soup tin used .. thank you
What size baking dish?
Hi Susanne, you can use two greased and floured round cake pans or a 9x13x2 sheet cake pan.
Next time you make your favorite molasses cookies, add a 1/4tsp of black pepper in with the dry ingredients. The black pepper steps up the flavor with out being noticeable.
My Momm use to make tomato soup cake and it taste very much like carrot cake but so much moister.Very good.
A little note for you….in the 1800’s the nuns in San Antonio were expecting an important Cardinal for a visit and wanted to make a special dish for him. They added chocolate to their spicy dish, and invented Mole’…….hence the expression. Holey Moley!
Not that it’s a secret or anything, but yesterday I threw about a teaspoon of regular yellow mustard into a sauce I had made from cream of mushroom soup and chicken broth. It added a nice savor.
Hi Paula, interesting! If it tastes good, go with it! Thanks for sharing!
