Ingredients You’ll Need
Getting started with the Chocolate Mayonnaise Cake Recipe is a breeze, thanks to its simple yet powerful lineup of ingredients. Each plays a distinct role in pulling the cake together—from creating fluffiness to enriching the taste and ensuring a beautiful color that looks as good as it tastes.
- All-purpose flour: Provides the sturdy foundation and structure for this cake’s tender crumb.
- Granulated sugar: Sweetens the cake perfectly without overpowering the chocolate notes.
- Unsweetened cocoa powder: Brings intense chocolate richness and a deep brown hue.
- Baking soda: Helps the cake rise beautifully and maintain its light texture.
- Baking powder: Adds extra lift for a tender bite.
- Salt: Balances flavors and enhances the chocolate’s depth.
- Mayonnaise: Holds the secret magic by keeping the cake moist—think of it as a creamy binder that surprises everyone.
- Water or brewed coffee: Liquids that thin the batter and deepen the chocolate flavor, especially if coffee is used.
- Vanilla extract: Provides a warm, fragrant nuance that rounds off the flavor perfectly.
How to Make Chocolate Mayonnaise Cake Recipe
Step 1: Preheat and Prepare the Pans
The very first thing you want to do is preheat your oven to 350°F (175°C). This ensures an even temperature from the moment your cake goes in. Grease and flour your preferred pans—two 9-inch rounds or a 9×13-inch pan are ideal. This prep prevents sticking and helps achieve that perfect crust on your cake edges.
Step 2: Mix the Dry Ingredients
Grab a large bowl and whisk together flour, sugar, cocoa powder, baking soda, baking powder, and salt. This step is crucial because it distributes all the raising agents and flavors evenly, which ensures a consistent texture throughout the cake.
Step 3: Add the Wet Ingredients
Next, stir in the mayonnaise, water or coffee, and vanilla extract. Be gentle and mix until the batter is smooth without overmixing—it’s this delicate fold that keeps your cake from becoming dense or tough. The mayonnaise will blend right in, making the batter luscious and rich.
Step 4: Pour Batter and Bake
Divide the smooth batter evenly between your prepared pans and smooth the cake tops with a spatula. Pop them in the oven—round pans for about 25 to 30 minutes or the 9×13-inch pan for 35 to 40 minutes. Keep an eye out for the classic toothpick test: it should come out clean, signaling your cake is perfectly baked through.
Step 5: Cool and Frost
That wonderful chocolate aroma will have you itching to dig in, but patience is key! Let your cake rest for 10 minutes in the pans before transferring to a wire rack to cool completely. Frost only when completely cool to avoid melting your frosting. This step guarantees a neat, flawless finish every time.
How to Serve Chocolate Mayonnaise Cake Recipe

Garnishes
To brighten the deep chocolate tones, fresh berries like raspberries or strawberries make stunning contrast both in flavor and color. A dusting of powdered sugar or a scattering of chopped nuts adds a little texture and visual appeal that invites everyone to take that first bite.
Side Dishes
A scoop of vanilla or coffee ice cream pairs beautifully with the warm, moist cake, creating a match made in dessert heaven. You can also serve it alongside a simple whipped cream or a drizzle of caramel sauce to enhance its dessert-party status.
Creative Ways to Present
If you’re feeling adventurous, slice the cake into rectangles and layer with mascarpone or cream cheese frosting to create a quick tiramisu-inspired dessert. For celebrations, adorn the top with chocolate curls or edible flowers to impress guests with a whimsical, elegant look.
Make Ahead and Storage
Storing Leftovers
Once frosted, keep your chocolate mayonnaise cake covered tightly at room temperature for up to two days for optimal freshness. If your kitchen is particularly warm, refrigeration is a better option but bring the cake back to room temperature before serving for the best texture.
Freezing
This cake freezes wonderfully. Wrap it tightly in plastic wrap and then an aluminum foil layer to avoid freezer burn. It will keep well for up to three months. When ready to enjoy, thaw it overnight in the fridge.
Reheating
If you prefer a slightly warm slice, microwave individual pieces on low heat for 10-15 seconds. This little warmth wakes up the chocolate flavor and makes the cake even more comforting to munch on.
FAQs
Why use mayonnaise in a chocolate cake?
Mayonnaise may seem unusual but it’s actually an amazing ingredient that adds moisture and richness to the cake. It replaces butter or oil but keeps the crumb dense and tender, making the cake beautifully moist for days.

Can this recipe be made gluten-free?
Yes, by swapping the all-purpose flour with a gluten-free blend designed for baking, you can enjoy a gluten-free version. Just ensure your cocoa powder and other ingredients are certified gluten-free to avoid cross-contamination.
