One tiny kitchen secret equals one very good cake.
My kids love helping me bake, which is both sweet and exhausting. I’m all for encouraging confidence in the kitchen, but between the spills and the constant requests for help, I spend almost as much time directing traffic as I do baking. At this stage of parenting, that chaos just comes with the territory. But there’s one part of the process I always handle alone. My kids have a very short list of foods they absolutely refuse to eat, and one of them just happens to be my favorite baking secret. If they saw me adding this ingredient, dessert would be over before it even made it into the oven.
So when it’s time to add this ingredient, I start handing out suspiciously well-timed jobs to my kids. Someone needs to search the pantry for vanilla. Someone else should check the position of the oven rack. Maybe the dogs need to go outside, just in case. None of those things are actually urgent; I just need about 10 uninterrupted seconds. That’s how long it takes to stir in the ingredient that makes a boxed cake mix taste homemade.
What ingredient makes boxed cake mix taste homemade?
Mayonnaise.
I know. It sounds like the sort of kitchen advice invented to prank people on the internet. But it’s actually a classic baking trick, and there’s some solid science behind it. Mayonnaise is essentially just oil and egg yolks, held together with a little vinegar or lemon juice. Those are all ingredients you’d happily add to a cake made from scratch. Adding mayonnaise simply enriches the batter with a little more fat and extra emulsifiers. The result is a finer, more tender crumb and a cake that stays moist rather than going stale too soon.
Making a mayonnaise cake doesn’t make the cake taste like a deli sandwich, either. Instead of tasting tangy, the flavor subtly balances the sweetness and can even deepen the cake’s flavor.
How to Use Mayonnaise in a Cake Mix
Simply add 2 to 3 tablespoons of full-fat mayonnaise to the cake batter along with the ingredients listed on the box, then mix and bake as directed. Because you’re adding such a small amount, there’s no need to adjust the rest of the recipe. The mayonnaise improves the texture without changing the flavor, so the finished cake tastes richer and stays moist longer.
I use this trick most often with chocolate cake mix because that’s where the difference is most noticeable, but it works just as well in yellow, white and spice cakes.
My kids still have no idea what’s in the batter. They wrinkle their noses at mayonnaise before it’s even within arm’s reach of a sandwich, so I know exactly how that conversation will go. Instead, I quietly stir it in when they’re not looking, slide the cake into the oven and wait for the inevitable chorus of, “This is so good, Mom!”
Maybe one day I’ll tell them my secret. But as long as they keep asking for a second slice, I don’t see much reason to ruin a good thing.
