Ingredients
1 ¼ cups/160 grams all-purpose flour
1 cup/200 grams granulated sugar
⅓ cup/30 grams unsweetened cocoa powder
¾ teaspoon baking soda
½ teaspoon kosher salt
⅓ cup/80 milliliters canola oil
1 teaspoon vanilla extract
1 teaspoon apple cider vinegar or white vinegar
2 tablespoons semisweet or vegan chocolate chips (optional)
Confectioners’ sugar, for dusting on top (optional)
Preparation
- Step 1
Heat oven to 325 degrees. Add the flour, sugar, cocoa powder, baking soda and salt to an 8-by-8-inch square glass or metal baking dish. Whisk the mixture together until uniform in color. Use your fingers to break apart any lumps.
- Step 2
Add 1 cup water along with the oil, vanilla extract and vinegar. Stir slowly with a fork or a whisk in small circles to blend. Mash, scrape and stir with a fork and spoon until the mixture becomes a smooth and uniform batter.
- Step 3
Scrape the sides of the baking dish with a rubber spatula and spread the batter in an even layer. Sprinkle with chocolate chips, if using.
- Step 4
Use a damp paper towel to wipe the edges of the baking dish clean. Carefully transfer the dish to the oven and bake until a toothpick inserted into the center of the batter comes out mostly clean, 28 to 33 minutes. (Instead of looking like you dipped the toothpick in chocolate frosting, it should look like it has some chocolate cake crumbs clinging to it.)
- Step 5
Remove from the oven, let cool, then cut the cake into squares. If you’re feeling fancy, this tastes good (and looks pretty) with some confectioners’ sugar dusted on top.

I know this recipe as Wacky Cake. There's also easy variations on it. Double the recipe, put it in round 9" pans and it makes a wonderful layer cake with any kind of frosting (make in mixing bowl and grease pans first). Swap out the chocolate for an extra teaspoon or two of vanilla, and you have an excellent white/vanilla cake. I use this when I make strawberry shortcake. For a spice cake, omit chocolate and throw in cinnamon, ginger, nutmeg and clove.
I've been making this "Wacky Cake" for decades. It's a lot easier to whisk it up in a bowl and pour it into the cake pan, IMHO.
As others have noted, this is a variation of Wacky Cake or Crazy Cake. It is tasty and easy to put together. The recipe doubles easily, and can be made in a 13x9 pan. Instead of 1 cup water, we often use one-half cup water and one-half cup strong coffee. The coffee adds a nice layer of flavor to the chocolate.
I’ve been making this concerningly often since the pandemic, and love love love! I have the recipe practically memorized haha. My biggest tip is about the cup of water: make a shot of espresso first, in a measuring cup, and then fill it up to the 1 cup line — doesn’t mess with the texture but makes it oh so good!
Really should list the 1 cup of water (or, even better, coffee) in the ingredients list, which would be helpful for beginners who haven't learned to study the instructions.
I had leftover coconut milk and used that instead of water. Came out delicious. I agree with others that it would be great to add water or liquid into the ingredients list especially since it’s a mix and bake in one bowl recipe!
