No eggs, no milk, no butter… and yet, this is one of the richest, most satisfying chocolate cakes I’ve made. Known by many names—Crazy Cake, Wacky Cake, Depression Cake or Emergency Chocolate Cake—this unfussy dessert has its roots in the Great Depression, when eggs and dairy were scarce but the need for chocolate cake remained (understandably) strong. In the modern era, this recipe checks the ‘vegan’ box.
The ingredients are minimal and pantry-friendly. Cocoa powder (unsweetened, please) stands in for bar chocolate. I used Dutch process cocoa here, which gives it a deeper flavor, but natural cocoa also works beautifully. The traditional liquid of choice was water, but this recipe calls for brewed coffee, which enhances the chocolate flavor. I used decaf since that’s what we keep on hand, and it works in both the cake and the icing. You’ll need about 1-3/4 cups total—brew once and cool it.
Speaking of icing, it’s a smooth, luscious chocolate-coffee situation that gets slathered on while the cake is still tucked in its baking dish. I served it straight from the dish—and honestly, it’s that kind of cake. If you do want to transfer the cake to a plate, I recommend lining the bottom of the pan with parchment paper.
A little tip: don’t overmix the batter. A gentle stir is all it needs to keep the crumb tender and the rise intact.
I added a dash of coffee extract (from Nielsen Massey, same as my go-to vanilla) for extra oomph to the batter—one teaspoon coffee extract and two teaspoons vanilla in place of the standard tablespoon of vanilla. All vanilla is fine too.
We brought this to dinner with my uncle, John F, and cousin, Bill M, and it hit the chocolate-loving sweet spot. Ed gave it an enthusiastic thumbs-up as well. It’s easy, deeply chocolatey, and one I’ll make again and again.
This cake feels right at home on a Valentine’s Day table, but it’s just as fitting for the Super Bowl. When I reached out to my friend Elisabeth R in Seattle for game-day food inspiration, she suggested something with coffee—naturally. So here you have it: a chocolate cake with a coffee kick—perfect for watching the Seattle Seahawks face off against the New England Patriots in Super Bowl LX.
Crazy Chocolate Cake
Ingredients
Cake
- 2 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder see Notes
- 1-1/4 cups packed light or dark brown sugar
- 1-1/4 teaspoons baking soda
- 1/2 teaspoon Kosher salt
- 1-1/4 cups coffee room temperature
- 1 cup neutral oil see Notes
- 1 tablespoon white vinegar
- 1 tablespoon vanilla extract see Notes
Icing
- 1-1/4 cups powdered sugar
- 1/4 cup unsweetened cocoa powder see Notes
- 3 to 4 tablespoons coffee room temperature
- 2 teaspoons vanilla extract
- 1 teaspoon neutral oil see Notes
Instructions
- Brew about 1-3/4 cups of coffee (regular or decaffeinated)—enough (with a little extra) for both the cake and icing. Cool to room temperature. Coffee can be prepared up to 1 day in advance and refrigerated.
Make cake:
- Heat the oven to 350°F with a rack in the middle position. Mist the bottom of an 8-inch square glass baking dish or metal baking pan with cooking spray. Line with a square of parchment paper (see Notes). Mist the sides of the glass baking pan. Set aside.
- In a large bowl, whisk together the flour, cocoa, brown sugar, baking soda and salt, breaking up any lumps of cocoa and sugar.
- Make a well in the center and to it add the coffee, oil, vinegar and vanilla (and coffee extract, if using). Whisk the wet ingredients to combine, then whisk them into the dry ingredients just until evenly moistened. The batter will be fluid. (Don’t overmix the batter, which will develop gluten and cause the cake to have a firmer, tougher texture. It also won’t rise properly.)
- Pour the batter into the prepared baking dish. Bake until a toothpick inserted at the center of the cake comes out clean, 50 to 55 minutes.
- Cool completely in the pan on a wire rack.
Make icing:
- When the cake has cooled, make the icing.
- In a large bowl, whisk the sugar and cocoa until no lumps remain.
- Add 3 tablespoons coffee, vanilla and oil. Whisk until smooth.
- The icing should be thick but spreadable, with a consistency similar to pourable yogurt. If it is too stiff, whisk in additional coffee 1 teaspoon at a time until the proper consistency is achieved.
- Pour the icing onto the center of the cake in the pan, then spread evenly.
- Let stand at least 30 minutes before cutting and serving.
Notes
- You can use either Dutch-processed cocoa or natural cocoa works, just be sure it is unsweetened.
- For the batter, I used refined coconut oil which lends a neutral taste and avoids seed oils. You can also use the same amount of vegetable or canola oil. If using coconut oil, measure 1 cup of coconut oil in a dry measuring cup (like one used to measure flour) or 225 grams if using a scale. Transfer it to a glass measuring cup or bowl. Microwave on high in 15 second intervals until just melted, stirring occasionally. Let cool slightly before mixing it into your batter.
- For the batter, if you have coffee extract, use 2 teaspoons vanilla extract and 1 teaspoon coffee extract to replace the 1 tablespoon of vanilla extract (1 tablespoon = 3 teaspoons).
- For the frosting, I used olive oil since it’s such a small amount.
- If you want to remove the cake from the baking pan before icing it, I recommend putting a piece of parchment paper on the bottom of the pan. Cut around the sides and release onto a plate and invert it onto another plate. Then pour the icing on top. Once the icing is on the cake in the baking pan, you will not be able to remove the full cake. This is the kind of cake that’s fine to leave in the baking pan for serving.

That looks and sounds amazing!
Linda – Thank you! So yummy and easy, too.
With this post and recipe, I am transported to my grandmother’s home growing up. She would make Wacky Cake regularly and my mouth waters just reflecting on the memories. And coffee in the recipe! Who knew?!? Thank you for the inspiration and formula to remake this delicious childhood delight. Can’t wait to make it in our kitchen!
Spenser – Ah, what a wonderful story! And, it’s vegan already so no need to make any changes.
Mark’s family knew it by Wacky cake. It is a great recipe, as were many of those from the Great Depression.
David – A good cake and funny naems, too. Agree that it’s a good recipe. Thank you for sharing.
