• 2/3 cup (57.33g) cocoa powder (unsweetened)
• 1 tbsp baking powder
• 1 tsp espresso powder (optional, but enhances chocolate flavor)

• 3 large eggs (room temperature)
• 1/3 cup (78.86g) water
• 1 tsp vanilla extract

For the Dairy-Free Chocolate Frosting

• 2 ounces (56.7g) unsweetened chocolate, chopped
• 3/4 cup plus 1 tbsp coconut oil, divided

• 1 cup (182g) powdered Swerve Sweetener
• 1 tsp vanilla extract
• 1/3 to 1/2 cup (75.33g) full-fat coconut milk

Ingredient Substitutions and Notes

• Sweetener options: If you don’t have Swerve, you can use other keto-friendly sweeteners like monk fruit, erythritol, or allulose (adjust quantities as needed since sweetness varies).
• Flour alternatives: For the best keto mayonnaise cake with almond flour, stick with blanched almond flour. Coconut flour is not a 1:1 substitute.
• Mayo matters: Use full-fat, sugar-free mayonnaise for the best texture and flavor in your moist chocolate cake with mayonnaise keto creation.
• Dairy-free options: The frosting recipe is already dairy-free, but ensure your mayonnaise is also dairy-free if needed.

How to Make Keto Chocolate Mayonnaise Cake – Step by Step

Preparing the Cake Batter

Step 1: Preheat your oven to 350°F (175°C). Line two 8-inch round cake pans with parchment paper and grease the sides with butter or coconut oil.

Step 2: In a large mixing bowl, combine all dry ingredients: almond flour, Swerve sweetener, cocoa powder, baking powder, espresso powder (if using), and salt. Whisk thoroughly to remove any lumps.

Step 3: In a separate bowl, whisk together the mayonnaise, eggs, water, and vanilla extract until smooth and well combined.

Step 4: Gradually add the wet ingredients to the dry ingredients, stirring gently until just combined. Be careful not to overmix – this low carb chocolate mayonnaise cake recipe works best with a gentle touch.

Step 5: Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula.

Baking the Cake

Step 6: Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted into the center comes out clean with just a few crumbs.

Step 7: Remove from the oven and let the cakes cool in their pans for 10 minutes before transferring to a wire rack to cool completely. This easy chocolate mayonnaise cake for keto diet needs to be fully cooled before frosting.

Making the Dairy-Free Chocolate Frosting

Step 8: In a small microwave-safe bowl, combine the chopped unsweetened chocolate with 1 tablespoon of coconut oil. Microwave in 20-second intervals, stirring between each, until fully melted. Set aside to cool slightly.

Step 9: In a large mixing bowl, beat the dairy-free cream cheese with the remaining 3/4 cup coconut oil until smooth and fluffy.

Step 10: Add the powdered Swerve and vanilla extract, continuing to beat until well combined.

Step 11: Pour in the melted chocolate mixture and beat until incorporated.

Step 12: Gradually add the coconut milk, 1 tablespoon at a time, until you reach your desired frosting consistency

Pro Tips for Making the Best Keto Chocolate Mayonnaise Cake

• Room temperature ingredients: For the most moist chocolate cake with mayonnaise keto version, ensure your eggs and mayonnaise are at room temperature before mixing.
• Don’t rush cooling: Cooling is crucial for this sugar free keto mayonnaise chocolate cake – if you frost it while warm, your frosting will melt and slide off.
• The secret to extra richness: Adding that optional espresso powder doesn’t make the cake taste like coffee – it intensifies the chocolate flavor in your decadent keto chocolate cake with mayonnaise.
• Even baking: For perfectly even layers, use a kitchen scale to divide your batter exactly between the pans.
• Frosting consistency: If your frosting is too thick, add a bit more coconut milk. If it’s too thin, refrigerate it for 10-15 minutes before spreading.
