Troy Chocolate Cake is a recipe I found years ago in my mom's binder full of old recipe clippings. I believe it is from a friend in Troy, New York and that's how it got its name, but it's still a mystery!
Update: Thanks to some wonderful people in the comments section, the mystery is solved! The recipe appeared on a utility bill and brochures in Upstate New York, and was submitted by someone from Troy.Jump to Recipe
It is an easy 8 inch square pan one layer chocolate mayonnaise cake with a chocolate and sour cream flavored frosting.
Troy Chocolate Cake Texture
Here's a picture of the cake's texture.
Troy Chocolate Cake Ingredients
As mentioned, this is a mayonnaise cake. Mayonnaise stands in for butter and oil, but it does not completely take the place of eggs, as there is one egg in the recipe. The other ingredients are pantry staples. The recipe calls for all-purpose flour rather than cake flour, natural cocoa powder and granulated sugar.
Chocolate Sour Cream Frosting
The recipe includes my favorite type of chocolate frosting, which is one made with sour cream and natural cocoa powder. And this one has a lot of sour cream! If you are not so fond of sour cream, you can use your personal favorite. Or maybe try it with vanilla flavored cornstarch frosting.
- The cake does not require an electric mixer, but the frosting does.
- You can use an 8 inch metal pan or an 8 inch glass dish.
- The amount of salt in the original recipe was ½ teaspoon, but lately I've been cutting it down to ¼ teaspoon. The mayonnaise seems to have plenty of salt.
- I make this cake with natural cocoa powder rather than Dutch process.
- For the frosting, the butter should be very soft -- almost melted. The sour cream should be brought to room temperature unless you are okay with little brown dots of cocoa.
- The amount of confectioners' sugar is measured after sifting. It needs to be sifted for proper measuring by volume and to help keep the frosting smooth.

- You can use a metal pan or a glass baking dish.
- You can mix the batter with a spoon or scraper. No need to use an electric mixer.
- Since the recipe calls for baking soda and no baking powder, I use natural cocoa, which is more acidic than Dutch process. I still haven't tried this with Dutch process.
