Mayonnaise Chocolate Cake Recipe: Easy Moist Mayocake 2026

This mayonnaise chocolate cake may sound unusual, but it makes perfect sense once you think about it. Mayonnaise is simply an emulsion of eggs and oil—the same ingredients that give a classic cake its tender crumb. The result is a deeply chocolatey, wonderfully moist cake that comes together with just six everyday ingredients.

The batter mixes up in minutes with a whisk, so it's a great choice for busy days or beginner bakers. A 20 cm (8-inch) pan yields twelve generous slices, ideal for breakfast, an afternoon snack, or as a sturdy base for layer cakes and frostings.

Because the mayonnaise already contains eggs and oil, there's no need for additional butter or eggs. The cake bakes low and slow at 160 °C (320 °F) for an hour, developing a rich flavor and a beautifully even rise. Let it cool completely before slicing for the cleanest cuts.

Ingredients for Mayonnaise Chocolate Cake

Makes 12 servings

• 250 g granulated sugar
• 275 ml mayonnaise
• 275 g all-purpose flour
• 30 g unsweetened cocoa powder
• 15 g baking powder
• 250 ml water

How to Make Mayonnaise Chocolate Cake Step by Step

1. Beat the sugar with the mayonnaise

For the best result, bring all ingredients to room temperature before you begin. Using an electric whisk (a manual one works too), beat 250 g sugar with 275 ml mayonnaise for 3 minutes until smooth. Preheat the oven to 160 °C (320 °F).

2. Sift the dry ingredients

In a separate bowl, sift together 275 g all-purpose flour, 30 g unsweetened cocoa powder, and 15 g baking powder. Sifting ensures an even distribution of the leavener and prevents lumps in the cocoa.

3. Combine everything into a batter

Add the sifted dry ingredients to the mayonnaise-sugar mixture while pouring in 250 ml water. Whisk gently until just combined and smooth; avoid overmixing to keep the cake tender.

4. Fill the pan

Line a 20 cm (8-inch) round pan with parchment paper, or grease and lightly flour it for easy release. Pour the batter into the prepared pan and smooth the top with a spatula.

5. Bake, cool, and unmold

Bake at 160 °C (320 °F) for 1 hour, or until a toothpick inserted in the center comes out clean. Remove the pan from the oven and let it cool for 5 minutes on a wire rack without unmolding. Then turn the cake out and let it cool completely on the rack before serving.

Tips for the Best Mayonnaise Chocolate Cake

Use room-temperature ingredients

Let the mayonnaise and water sit out for about 30 minutes before mixing. Room-temperature ingredients emulsify more easily, giving the batter a smoother texture and a more even rise.

Prepare the pan properly

Line the pan with parchment paper, or grease it with butter and dust lightly with flour. This guarantees the cake releases cleanly after baking without tearing the delicate crumb.

Adjust for a larger pan

If you use a wider pan, reduce the baking time and start checking early. Always test with a toothpick in the center—it should come out clean when the cake is done.
