Yes, it is possible! This sponge cake is very delicious, prepared very simply, easily, and quickly in the microwave! Perhaps, this is the quickest recipe for sponge cake. The sponge cake can be cut in half, soaked with syrup, and spread with cream. You can also use yogurt, jam, condensed milk, etc.
To make chocolate sponge cake in 10 minutes, beat the egg slightly together with sugar.
Add the remaining ingredients: cocoa, milk, oil, flour, and baking powder. Mix everything, the batter should not be thick.
Take a suitable form for the microwave, grease it with oil (you can put parchment paper on the bottom), pour our batter and place it in the microwave for 5 minutes on full power. (I have 800 watts)
That's it, chocolate sponge cake in 10 minutes is ready! Enjoy!
