You are about to be let in on a life changing hack! Who would guess, the humble mayonnaise could replace the key ingredients in a cake and turn it into my favorite chocolate cake recipe. Like you, I have always put off the idea. Seriously, mayonnaise in cake? So wrong! No, actually I was wrong! I only discovered this while testing out recipes for a favorite brand of mayonnaise (Hellmann’s).
Look at this cake! So simple, yet so cool, right? Not only will this be up there with your go-to recipes in future but you just can’t have enough of this cake. I know the question that you are busting to ask me. Will it taste anything like mayonnaise? The answer is NO! It does not taste of mayonnaise if you use a good quality one. The mayonnaise is there to work it’s magic in the cake to make it extra moist and simplify things for you. If you think about it, mayonnaise is nothing but eggs, oil and vinegar. All of these ingredients are used in varieties of cakes in different ways. To rule out this possibility to a great extent, I’ve included coffee in the recipe. You know how coffee enhances the flavour in chocolate cakes.
I have used a Chocolate Fudge Frosting to frost the cake. Chocolate ganache will work as well or any other chocolate frosting that you love. The idea is to keep things simple. To decorate the cake I’ve grated a block of dark chocolate and stuck them on the sides of the cake with my hand. I hope you try the recipe. Let me know how you like it:-)
Chocolate Mayonnaise Cake
Makes a round 6 inch cake
1 tablespoon instant coffee
11/2 cup self-raising flour
3/4 of a tsp, baking soda
3/4 cup castor sugar (or more if you like it sweeter)
3/4 cup mayonnaise, (I used Hellmann’s Real Mayonnaise)
1/4 cup cocoa powder (preferably Dutch processed)
Preheat oven to 180 degrees C. Lightly grease a 6 inch pan and line the base with non-stick baking paper.
Mix the instant coffee with 3/4 cups lukewarm water. Leave aside to cool completely.
Place the flour, baking soda, cocoa and sugar in a large bowl. Mix together with a large spoon. Add the mayonnaise and coffee mixture and mix till well blended. Pour into the prepared pan.
Bake for 30 minutes or until a wooden skewer inserted in the middle of the cake comes out clean. Remove from the oven. Leave in pan for 10 minutes. Turn out onto a wire rack to cool completely, Once cool, spread frosting on the top and sides. I have used a chocolate fudge frosting (recipe below). You could use the same or your favourite chocolate frosting recipe. Decorate the sides with grated dark chocolate and top with fresh raspberries.
Chocolate Fudge Frosting (this recipe will yield more frosting than you will need for the cake. You could either half the recipe or store the extra frosting for use later on)
120 gms unsweetened chocolate, coarsely chopped
2/3 cup (150 gms) unsalted butter, room temperature
11/3 cups (160 gms) icing sugar sifted
11/2 tsp pure vanilla extract
Melt the chocolate in a heatproof bowl over a pot of simmering water. Remove from heat and let cool to room temperature.
In the bowl of your electric mixer, or with a hand mixer, beat the butter until smooth and creamy(about 1 min). Add the sugar and beat until it is light and fluffy(about 2 min). Beat in the vanilla extract. Add the chocolate and beat on low speed until incorporated. Increase the speed to medium-high and beat until frosting is smooth and glossy (about 2-3 min).

What a gorgeous looking cake. I cannot believe it has been made with mayonnaise! It looks wonderful.
Well done Sonali.
Sugar et al says
Thank you so much Angela! yes it s incredible that mayonnaise can be used in a sweet recipe.
Good morning Sonali!!!!! When I saw this photo yesterday on IG, I was taken back to my youth. My mother successfully experimented with mayonnaise OR sour cream in her chocolate cakes, and to this day, I think my mom’s chocolate cake was the best I’ve ever had. I even remember her using Coca Cola in her cakes and a friend reminded me of 7up cake!
A gorgeous and bold creation for the month of LOVE!!!!!! Hugs to you dear one!
Wow! A cola cake. I’m so intrigued. Thanks so much for your lovely comment always my dear Anita.
Wonderful looking cake Sonali. At first I thought ….. What !!!!!!! but thinking about it, I suppose mayonnaise is really just made from eggs, oil and lemon juice and these are all ingredients we would use happily in our baking without thinking twice. I agree with Anita, a bold creation indeed.
This is one cake I am definitely going to make. Thanks for your beautiful inspiration as usual
Thanks dear Ev! This is truely a cake worth trying.
Ok so long I only thought you were an artist. Wrong. You are a scientist too Sonali!!
Aww….totally made my day. Thank you dear Ratna.
Hey, i tried this cake just day before yesterday and it tasted great and was extremely moist but my cake didnt rise at all. I followed the recipe in detail and i bake quite often so i didn’t understand why my cake didnt rise. My baking soda and self raising flour were perfectly fine also.
I’m glad you tried the cake Faiza. Thanks so much. This cake wont have a great rise yet is very moist and fudgy. Did you use Hellmann’s mayonnaise?
All hail the mayo cake! My trick is, just don’t tell people what’s in it til after they try it. 🙂 this is a beauty!
Hi Sonali, may I ask which unsweetened chocolate brand you used? I’m having trouble finding a good quality one.
Hi Michelle, I normally use Lindt 70% for glazes and ganache. For baking, I mostly use the cooking chocolate from my local supermarkets in Australia. Where are you based?
I’m based in Sydney!
