This Chocolate Mayonnaise Cake is your go-to for chocolate cravings. With nostalgic charm, it offers moist, tender crumbs and indulgent chocolate flavor. Top it with a luscious chocolate ganache for the ultimate irresistible treat, ready in just 40 minutes.
Preheat the oven to 350 F and grease a 13 x 9 inch pan with baking spray.
In a large bowl mix flour, baking powder, baking soda, cocoa powder, castor sugar and salt together. Whisk well and set aside.
In another bowl, add mayonnaise and whisk it. Add boiling water and vanilla essence to mayonnaise and mix until combined.
Add the wet mixture to the dry ingredients. Incorporate until combined.
Pour the cake batter in the sheet pan and place the cake pan in the middle rack of the preheated oven.
Bake the cake for 25 – 30 minute or until a skewer or tooth pick inserted in the middle of the cake comes out clean. The sides of the pan will start to pull away or shrink a little.
Chocolate Ganache
Add the semisweet chocolate chips to a bowl and set aside.
Add butter to the heavy cream and place in the microwave and warm it up in 30 seconds interval until the butter has melted and the heavy cream is about to boil with simmering bubbles on the top of the cream.
Pour this cream mixture over the chocolate chips and let it sit for a minute or two. Then whisk it until the ganache is smooth and silky.
Let the cake cool down completely and then pour over the ganache.
Notes
For a richer color and smoother taste, useDutch-process cocoa, which doesn't affect leavening like baking soda, thanks to its neutral pH.
Patience is key. Let the cake cool completely before frosting or cutting. The soft crumb needs time to set, or it may crumble when you try to handle it. Trust us, it's worth the wait for a beautifully intact cake.
For a smooth cake texture, ensure the sugar dissolves completely. Use boiling water to help melt the sugar after combining wet and dry ingredients. Opting for caster sugar, also known as superfine sugar, further aids in quick dissolving and prevents a grainy texture.
For clean, smooth cake slices, dip a sharp knife completely in the hot water for a few seconds. Wipe the blade dry with a clean cloth or paper towel. While the blade is still warm, cut through the cake. Repeat the steps before each cut.
