Why Mayonnaise? The SECRET Ingredient!

Okay, I know, mayo in cake sounds weird. BUT, hear me out! It’s like a baking SUPERSTAR. Mayo has oil and eggs, which add SO much moisture, making the cake SUPER soft and yummy! It’s perfect for the best darn chocolate cake ever. Also, it’s cheap, made from super common kitchen ingredients. If you have mayo you don’t need anything!

Mayo also adds great flavor and richness, it makes the chocolate SO much better. Plus there’s some kind of magic that happens chemically, so that this becomes a delightful dish. You could not have something better for a dessert, and this thing was prepared within just 20 MINUTES, BAM.

How’s that? I kept the key points and the tone while making it more concise and snappier!

How To Make Chocolate Mayonnaise Cake

Okay guys LET’S get right down to business (the cake one!). Here’s the whole breakdown on this DELICIOUS project. Don’t you even WORRY this WILL be super easy!:

Cake Prep:

Preheat & Prep: 

First things first, heat your oven to 350°F (175°C). Prepare your cake pans, I suggest grease it and put some flour so that it NEVER gets stock. 9inch rounds work best. However my mother has an older cake pan that is like 8.8 inches wide, but I’m using it and NO PROBLEMA. IT will come AMAZING

Mix your Dry Ingredients:

In a big bowl, mix together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. It MUST be THOROUGHLY, get it WELL. I just shake it with the bowl and it WORKS fine

Add the Wet Ingredients: 

Put mayonnaise, water, milk and vanilla in it. Make sure its really hot water (almost boiling). Trust me the difference is AMAZING and less clumps in your mix. And I prefer putting hot water rather than hot milk, the texture just comes better. Mix with mixer until EVERYTHING is SUPER combined!. Trust me guys no lumps should be in your bowl (almost a chocolate milky like liquid texture )

Pour and Bake: 

Split the batter into your cake pans (like it could fit two pans or three, however u please) and BAKE. Check in like 30 minutes to 40 minutes. Insert a toothpick. If it comes out clean it’s ready! NO STICKY STUFF!. Let the cake completely cool. I prefer making cakes a day in advance. But its all YOUR decision on that one!

Prep the Cake: 

Once everything has cooled to touch temperature and NOT HOT (wait overnight), then remove it form the molds and lets get decorating with that AMAZING frosting that is a total heaven combination.

Frosting time!:

  1. Whip the Butter with the electric mixture until SUPER creamy texture, then, in separate bowl add in your sifted powdered sugar, cocoa powder and vanilla extract
  2. Add this new mixture into the mixer to get it fully combined until its all together. Then SLOWLY, add the milk one tablespoon at a time. Be cautious not to get the whole mixture TOO milky
  3. Mix WELL. The mix should have a SUPER SMOOTH almost velvety feel texture!.

Assemble:

  1. Take a tiny bit of the frosting and put on the plate. That will allow the bottom part of the cake stay stable when frosting the rest
  2. Layer your cakes with the AMAZING chocolate frosting you did. Dont hold back use everything. Be GENEROUS, that cake will hold IT
  3. Then all set decorate the cake as you wish!! With sprinkles? chocolate bits? The WORLD is YOUR oyster here. You go be YOU! And have fun!.

And THAT IS IT!! you did a great job!!! you’re now THE CHOCOLATE mayonnaise CAKE CHEF. Give yourself a treat!!!

Why use mayonnaise in cake?

Mayonnaise makes cakes very moist because it has oil and eggs mixed inside! This makes the cake taste richer too!.

What makes a cake super moist?

Do not over mix it; Use quality and balanced ingredients!. Liquids and the correct fat creates also a great depth! and also makes the taste awesome!.

Tips and Tricks For The Best Chocolate Mayonnaise Cake

Here are some extra advice to make your life EASY and fun, just like it is supposed to be 😀

Room Temperature: Always use ingredients that are not frozen. (you want it at room temp always)

Good Cocoa: GOOD quality cocoa will improve your life dramatically with a wonderful rich flavor (try Ghiradelli!). That rich taste in the back will pay the extra dollar. TRUST ME ON THAT.

Don’t Overmix: Over mixing can make your cake dense, so mix until things are just combined (so follow the recipe closely and it will work SUPER!). Overmixing the mixture creates more of the gluten effect that creates the gluten in bread. Since we want to get that perfect SOFT cake consistency its not the goal we are reaching for so don’t over mix it!

Let It Cool: Be SUPER patient! Do not decorate when it’s hot, or you’ll have a mess and very gooey icing that slides all over the place, even a perfect chocolate layer melts and ruins everything!. Let your cakes cool ENTIRELY (OVERNIGHT is recommended. It tastes BETTER the day after!)

Try Different Flavors: You can add things like espresso powder or chocolate chips or mini marshmellows to get extra goodness

Why You MUST Try This Recipe

It’s the perfect way to surprise family and friend or a date! It’s also easy, quick, AND SO much fun to do. And its different so IT IS A GREAT surprise!!

This cake tastes so heavenly, rich and it is beyond AMAZING, yet SO simple. It also gives a great depth of flavor to it without actually trying that hard! This chocolate mayonnaise cake can bring an impressive dessert with something everyone has in the house, mayo! No need to run around buying a whole load of fancy ingredients to make a complex thing that honestly can fail badly

How much mayo do you use instead of one egg in a cake?

Mayonnaise IS NOT for replacement of the egg. In this recipe we dont do it, rather mayonnaise provides moisture for your baking recipe. If experimenting elsewhere, go slow since its case to case basis. And remember each mayo can also have different kind of moisture too!
