Ingredients for Decadent Mocha Mayonnaise Cake

All-purpose flour sets the structure of the cake, giving it body and form. The perfect mix with cocoa for a balanced texture.

Unsweetened cocoa powder is where our cake gets its rich chocolate flavor, so choose one you love.

Baking powder and baking soda are the dynamic duo ensuring the cake rises well and has a tender crumb.

Salt enhances all the sweet flavors, making everything pop just a bit more.

Granulated sugar and light brown sugar are used for sweetness and moisture, with the brown sugar adding a hint of caramel-like depth.

Mayonnaise might sound unusual, but it’s a tried-and-true secret for moist cakes, thanks to its fat content and acidity.

Brewed coffee adds moisture and enhances the chocolate flavor without overpowering it.

Eggs bind everything together and add richness to the cake’s texture.

Vanilla extract is the aromatic touch that rounds out the flavors beautifully.

Tips & Tricks

  • Ensure all ingredients are at room temperature for the best texture.
  • Use a good quality cocoa powder for the richest flavor.
  • Let the brewed coffee cool before adding it to the mix to avoid cooking the eggs prematurely.
  • Wrap the cooled cakes in plastic wrap and refrigerate for a few hours before frosting for easier handling and cleaner cuts.

Serving Suggestions

This cake pairs beautifully with a classic cream cheese frosting or a simple dusting of powdered sugar if you prefer something lighter. For an extra indulgence, serve it with a scoop of vanilla ice cream and a drizzle of chocolate sauce. It’s perfect for special occasions or when you just need a chocolate fix.

Decadent Mocha Mayonnaise Cake Recipe Walkthrough

First, preheat your oven to 350°F. This is crucial for even baking, so don’t skip it. While it’s warming up, grease two 9-inch round cake pans to ensure your cakes don’t stick.

In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Sifting helps mix the ingredients and avoid lumps, giving you a smooth batter later.

In another bowl, whisk the granulated sugar, brown sugar, and mayonnaise until smooth. This might take a bit of elbow grease, but it’s worth getting it creamy and well-combined.

Gradually add the brewed coffee, eggs, and vanilla extract to the sugar-mayo mixture. Stir it all together until you have a smooth blend.

Now, it’s time to bring the dry and wet ingredients together. Slowly incorporate the dry mix into the wet mixture, stirring gently until just combined. Over-mixing can make the cake tough, so be gentle.

Divide your batter evenly between the prepared cake pans. You want equal layers, so they bake evenly.

Bake them for 30 to 35 minutes. You’ll know they’re done when a toothpick inserted into the center comes out clean. Cool the cakes in their pans for 10 minutes, then turn them out onto a wire rack to cool completely.
