Chocolate Mayonnaise Cake: a story of unlikely friends in the cupboard.
You might find yourself asking, “Who would think of mixing chocolate and mayonnaise together?” Truth is, we didn’t invent this odd pairing. Recipes for chocolate mayonnaise cakes dates back to the World War I, a time when ingredients such as eggs, butter, and milk were scarce. Bakers discovered that mayonnaise served as a suitable substitute, as the oils kept cakes moist and created a brownie-like texture. This trend continued into the Great Depression and has lasted to this day.
Today, mayonnaise is replacing butter in our recipe for Chocolate Mayonnaise cake to create a velvety-smooth texture that will keep well for days. Don’t let the name scare you off. Think of this as a chance to broaden your knowledge of the cake world—plus there is still chocolate.
Before this you can experience this tasteful enlightenment, you’ll need to pick up ingredients for both the cake and the frosting. The list of ingredients for the cake looks like this:
2 oz bittersweet chocolate
⅔ cup cocoa powder
1 ¾ cup boiling water
2 ¾ cups all purpose flour
1 ¼ tsp baking soda
¼ tsp baking powder
1 cup sugar
1 cup packed light brown sugar
1 ¼ cup mayonnaise
2 tsp vanilla
Once you’ve gathered these, preheat oven to 375 degrees. Prepare two 9 inch cake pans by lining the bottoms with parchment paper and greasing the sides. Break or chop the bittersweet chocolate into small pieces, then place in a bowl along with the cocoa powder. Add the boiling water and whisk until the chocolate melts. Set the bowl aside.
Fill in a medium sized bowl with the baking soda, flour, and baking powder. Whisk until mixture is lump-free.
In yet another bowl, mix the two sugars with the mayonnaise. Whisk until all of the ingredients have blended together well.
Next, add 1/3 of the flour mix to the sugar mixture. Whisk together until the flour is incorporated, add 1/2 of the cocoa mixture, and whisk again until well mixed. Repeat this step, adding another 1/3 of flour with 1/2 (the rest) of the cocoa mixture. Then add the remaining flour. Whisk until the batter is smooth, then distribute the batter evenly between the two cake pans.
Bake at 375 degrees for 20-25 minutes. You can test the center of the cake by poking it with a toothpick; if it comes out clean then the cake is ready. Allow the cakes to cool in their pans. Once cooled, flip them so that the side that had been on the bottom of the pan is now facing up, and remove the parchment paper. Keep in mind that the end result is going to be something like a double-decker cake. Place the first layer on a large platter and cover with 1-1 ½ cups of frosting. Spread and smooth the frosting, then add the second layer on top of the first and continue icing. Serve this timeless recipe at room temperature.
It’s not a finished cake without the perfect frosting, and it’s not a finished recipe without the notes for the perfect frosting to pair. Here are the ingredients:
10 oz bittersweet chocolate
2 oz white chocolate
3 sticks of butter (at room temperature)
3 cups of confectioner’s sugar
1 Tbl vanilla
Place a pot of water on the stove over medium heat. Fill a small bowl with the bittersweet chocolate, then place the bowl over the pot of boiling water so that the bottom of the chocolate bowl is not touching the boiling water. Keep the chocolate there until it melts completely. Next, remove the bowl and add the white chocolate. Whisk the chocolates together until the white chocolate has melted. Try to resist eating this delicious mix of warm chocolate during this step.
If you own a stand mixer, use the paddle attachment for the next step. If not, a hand mixer will do. In a separate bowl, beat the butter until smooth. Add one cup of the confectioner’s sugar at a time and beat well after each addition. Throw in the vanilla, and while the mixer is running, steadily add the melted chocolate. Beat well until the mix is smooth. Scrape down at least once to make sure the butter is completely mixed with the chocolate.
Finally, the best step: enjoy your cake.
