What is Wacky Cake and Why is it Called That?!

Wacky Cake is an American classic that dates back at least 100 years. Some claim it originated around the time of World War I, others say it took off during the Great Depression or even World War II.

What most can agree on is that it came about during times when eggs, butter, and milk were in short supply or simply not available, so traditional cake recipes weren’t possible. And this inventive chocolate wacky cake was born! (learn more about the origin of Wacky Cake here.)

The Story Behind the Recipe

Like many of you, I’m sure, I grew up on this cake. My mom called it “Crazy Cake,” and it pains the nostalgic side of me to not call it the same thing. But in the interest of inclusive language, I’m going with the other popular name: Wacky Cake. It’s also sometimes called Depression Cake. Whether you call it crazy cake, wacky cake, or depression cake, it’s a chocolate cake that’s easy and delicious!

My mom made this cake at least once per month. She served up the big fluffy squares with a generous dollop of Cool Whip, which is a serving suggestion I highly recommend.

But it’s excellent with a light layer of chocolate buttercream, too.

Ingredients for chocolate wacky cake.

Ingredients

  • All-purpose flour – bleached or unbleached both work well.
  • Sugar – plain old granulated.
  • Baking soda – the leavener in our wacky cake, the baking soda reacts with the vinegar to make the cake rise.
  • Salt – I like to use fine-grain sea salt for baking. Table salt works, too.
  • Cocoa powder – I use plain ol’ Hershey’s unsweetened cocoa powder for chocolate wacky cake
  • Canola oil – for a moist, melt-in-your-mouth cake. Vegetable oil works, too.
  • Vinegar – I use white vinegar, but apple cider vinegar will work, too. Don’t leave this out or substitute! It’s a strong acid that reacts with the other ingredients to help the cake rise, and is crucial to the success of this recipe.
  • Pure vanilla extract – for sweet vanilla flavor.
  • Water – not usually considered an official ingredient, but crucial to the formation of wacky cake batter.

Recipe Variations & Substitutions

  • Enhance the chocolate flavor by replacing the water with a cup of strong brewed coffee.
  • To make it a vanilla wacky cake, omit the cocoa powder and double the vanilla extract.
  • Go frosting-less – it’s still delicious! I provide a recipe for small-batch chocolate frosting with this wacky cake recipe for a chocolate frosted wacky cake, but you can omit the frosting and dust with powdered sugar and/or serve with whipped cream. Or, if you’re all about the frosting, scroll down for a bunch of suggestions.

How to Make Wacky Cake

If you’ve never made chocolate depression cake, a.k.a. wacky cake, prepare to be amazed! It’s just a matter of mixing the dry ingredients together, making indentations and pouring in the wet ingredients, mixing it all together, and baking it.

  1. Add the flour, cocoa powder, sugar, baking powder, and salt to an 8×8 pan. You don’t even need to grease the pan first.

2. Mix the dry ingredients together with a whisk, and create three indentations. I like to make a larger indentation for the oil, which, if you want to channel your inner child, naturally creates a happy face! Score!

3. Then, pour the vanilla extract into one small indent, the vinegar into another, and the canola oil into the large indent.

4. Pour the water over the top.

5. Stir until combined. I like to use a flat whisk so I can really get into the corners, but a plastic spatula works great, too.

6. And then, it’s time to bake your wacky cake! Bake just until the middle is set and a toothpick inserted into the center comes out clean.
