FAQs

Why is it called “Wacky Cake”?

The cake is called “Wacky” because of its unconventional method—no eggs, milk, or butter, and everything is mixed directly in the baking pan.

Can I make this cake vegan?

It already is! Since it contains no animal products, it’s naturally vegan-friendly.

Is it okay to use apple cider vinegar instead of white vinegar?

Yes, apple cider vinegar works just as well and can add a slightly fruity note.

What type of oil should I use?

Any neutral oil, such as vegetable, canola, or sunflower oil, works great.

Can I double the recipe?

Absolutely. Double the ingredients and bake it in a 9×13-inch pan for about the same baking time.

Can I add frosting?

Yes, it’s delicious with a simple chocolate or vanilla frosting, or just a dusting of powdered sugar.

Is this cake dense or fluffy?

It has a tender, moist crumb that’s slightly fluffy but rich thanks to the oil and cocoa.

Can I use whole wheat flour?

Yes, but expect a denser texture. You can also use half whole wheat and half all-purpose for balance.

Can I make cupcakes with this batter?

Yes, pour the batter into lined muffin tins and bake for 18–22 minutes.

Does it taste like vinegar?

No, the vinegar is just there to activate the baking soda and doesn’t leave a noticeable taste.
