Chocolate Mayonnaise Cake: The Moistest Recipe You’ll Ever Bake

Chocolate Mayonnaise Cake: Prepare to be amazed! I know, I know, the name might sound a little… unusual. But trust me on this one, you are about to discover a cake that is unbelievably moist, rich, and intensely chocolatey. Forget everything you think you know about cake because this unexpected ingredient is the secret to a truly decadent dessert.

The origins of Chocolate Mayonnaise Cake are rooted in resourcefulness. During times of rationing, like the Great Depression and World War II, cooks cleverly substituted mayonnaise for eggs and oil, creating a surprisingly delicious and economical treat. Mayonnaise, with its blend of eggs, oil, and vinegar, adds a unique tang and incredible moisture to the cake, resulting in a texture that is simply divine.

What makes this cake so beloved? Beyond its intriguing history, it’s the taste and texture that truly win people over. The mayonnaise doesn’t impart a mayonnaise flavor; instead, it enhances the chocolate, creating a deeper, more complex flavor profile. The cake is incredibly tender, almost melt-in-your-mouth, and stays moist for days. Plus, it’s surprisingly easy to make, requiring minimal effort for maximum reward. So, are you ready to try something a little different and bake a cake that will have everyone asking for the recipe? Let’s get started!

this Recipe

Ingredients:

• For the Cake:
• 2 cups all-purpose flour
• 2 cups granulated sugar
• ¾ cup unsweetened cocoa powder
• 1 ½ teaspoons baking powder
• 1 ½ teaspoons baking soda
• 1 teaspoon salt
• 1 cup mayonnaise (full-fat is recommended)
• 1 cup hot water
• 4 teaspoons vanilla extract
• For the Chocolate Ganache:
• 1 cup heavy cream
• 12 ounces semi-sweet chocolate chips
• 2 tablespoons unsalted butter, softened

Preparing the Cake Batter:

1. Preheat and Prep: First things first, let’s get that oven preheated to 350°F (175°C). While it’s heating up, grease and flour a 9×13 inch baking pan. You can also use baking spray with flour already in it – that’s my go-to for ease! This will prevent the cake from sticking and make it a breeze to remove later.
2. Combine Dry Ingredients: In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Make sure everything is evenly distributed. This step is crucial for a consistent texture and even rise. I usually whisk for about 30 seconds to a minute to ensure everything is well combined.
3. Add Mayonnaise and Water: Now, add the mayonnaise and hot water to the dry ingredients. Don’t be scared of the mayonnaise! It’s the secret ingredient that makes this cake incredibly moist. Mix everything together until just combined. Be careful not to overmix at this stage, as overmixing can lead to a tough cake. A few lumps are okay.
4. Stir in Vanilla: Finally, stir in the vanilla extract. This adds a lovely depth of flavor to the chocolate. Mix until just incorporated. The batter will be quite thin, which is perfectly normal.

Baking the Cake:

1. Pour into Pan: Pour the batter into the prepared baking pan, spreading it evenly. The batter will be thin, so don’t worry if it seems like a lot of liquid.
2. Bake: Bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean or with just a few moist crumbs attached. Keep an eye on it after 30 minutes, as baking times can vary depending on your oven.
3. Cool Completely: Once the cake is done, remove it from the oven and let it cool completely in the pan before frosting. This is important because frosting a warm cake will cause the frosting to melt and slide off. I usually let it cool for at least an hour, or even longer if I have the time.

Making the Chocolate Ganache:

1. Heat the Cream: In a medium saucepan, heat the heavy cream over medium heat until it just begins to simmer. Watch it carefully, as you don’t want it to boil over.
2. Pour over Chocolate: Remove the saucepan from the heat and pour the hot cream over the chocolate chips in a heatproof bowl. Let it sit for about a minute to allow the heat to melt the chocolate.
3. Whisk Until Smooth: Gently whisk the chocolate and cream together until the chocolate is completely melted and the ganache is smooth and glossy. Be patient and keep whisking – it might take a few minutes.
4. Add Butter: Stir in the softened butter until it is fully incorporated and the ganache is even smoother and shinier. The butter adds richness and a beautiful sheen to the ganache.
5. Let it Thicken (Optional): If you want a thicker ganache, let it sit at room temperature for about 30 minutes to an hour, stirring occasionally, until it reaches your desired consistency. You can also refrigerate it for a shorter period, but be sure to check it frequently and stir it to prevent it from becoming too hard.

Frosting and Serving:

1. Frost the Cake: Once the cake is completely cool, pour the chocolate ganache over the top, spreading it evenly with a spatula. You can let the ganache drip down the sides for a more rustic look, or you can spread it neatly to the edges.
2. Chill (Optional): If you want the ganache to set up a bit more, you can chill the cake in the refrigerator for about 30 minutes before serving. This will make it easier to slice and serve.
3. Serve and Enjoy: Slice the cake and serve. This Chocolate Mayonnaise Cake is delicious on its own, but you can also serve it with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy!

Tips and Tricks for the Best Chocolate Mayonnaise Cake:

• Use Full-Fat Mayonnaise: While you can technically use light mayonnaise, full-fat mayonnaise will give you the best results in terms of moisture and flavor. The fat in the mayonnaise helps to create a tender and rich cake.
• Don’t Overmix: Overmixing the batter can lead to a tough cake. Mix the ingredients until just combined, and don’t worry if there are a few lumps.
• Use Good Quality Cocoa Powder: The quality of your cocoa powder will affect the flavor of the cake. Use a good quality unsweetened cocoa powder for the best results. Dutch-processed cocoa powder will give you a darker, richer flavor.
• Hot Water is Key: The hot water helps to bloom the cocoa powder, which intensifies the chocolate flavor. It also helps to create a moist and tender cake.
• Cool Completely Before Frosting: Frosting a warm cake will cause the frosting to melt and slide off. Make sure the cake is completely cool before frosting it.
• Adjust Ganache Consistency: If your ganache is too thin, let it sit at room temperature or refrigerate it for a bit to thicken it up. If it’s too thick, you can add a tablespoon or two of warm cream to thin it out.
• Add a Pinch of Espresso Powder: For an even deeper chocolate flavor, add a teaspoon of espresso powder to the dry ingredients. This will enhance the chocolate flavor without making the cake taste like coffee.
• Get Creative with Toppings: While the chocolate ganache is delicious on its own, you can also add other toppings to the cake. Try sprinkling it with chopped nuts, chocolate shavings, or a dusting of cocoa powder.
• Storage: Store leftover cake in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. The cake will stay moist for longer if stored in the refrigerator.

Variations:

• Chocolate Cupcakes: You can easily adapt this recipe to make chocolate cupcakes. Simply fill cupcake liners about ¾ full and bake for 18-20 minutes, or until a wooden skewer inserted into the center comes out clean.
• Chocolate Layer Cake: To make a layer cake, divide the batter between two 9-inch round cake pans and bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool completely before frosting.
• Peanut Butter Frosting: If you’re a fan of peanut butter and chocolate, try frosting the cake with a peanut butter frosting instead of chocolate ganache.
• Mint Chocolate Cake: Add a teaspoon of peppermint extract to the batter for a refreshing mint chocolate cake.
