Creamy Cocoa-Nutella sponge cake

Everyone loves short-cuts to some extent to save their energy, even if they deny it big time! And if you are a mom of small human beings with your hands completely full, you will love short-cuts of every little task, so that you can spend more quality time with your little ones.
Talking about taking short-cuts, let's not forget microwave cakes! They are one of my favourite desserts which takes up less time, less energy but taste delicious nonetheless.
Today's dessert: cocoa sponge cake with nutella and cream toppings (mmm pair it up with hot coffee and it's heaven on Earth!)
Ingredients:
For 1 cup all-purpose flour, you will need 3 medium eggs, 5-6 spoon cocoa powder, a little less than 1 cup sugar, 3 tablespoons melted butter, vanilla essence (2 drops), baking powder (1 teaspoon), half cup milk, nutella spread and cream as per desire.
Recipe:
In a blender, blend together eggs, sugar, baking powder, cocoa powder, milk, butter and vanilla essence. Take this mixture out in a bowl and mix in the flour thoroughly with a spatula. Pour this cake mixture in a greased microwave dish/bowl (which is greased with a little oil and flour) and microwave for 10-15 minutes. Your sponge cake is ready. Top it with nutella, cream and chocolates chunks to make it moist and super gooey.
