I followed this to a T and popped the mixture into two glass ramekins and popped them in the oven at gas mark 6 for 10 minutes watching they rose to a peak only they were gooie in the middle spongy round the outside and crunchy on the top and how scrummy it tasted :)

When making these recipes, I've learned you don't really need the egg. I have used a part of the egg or no egg at all. It comes out better. An egg will make it spongy. I don't know why they always say to use 1 whole egg.

If you want this to taste amazing and be like a real molten chocolate cake after making the mixture mix 1 teaspoon of cocoa and 2 of sugar then sprinkle over the top and add hot water over the cocoa and sugar then cook omg it's amazing (also no need to mix the cocoa-sugar and water together or into the rest of the mixture)

I'm not sure what everyone's issue was. Tastes like a mug cake to me. I added a 1/2 tsp of baking powder and scaled back the sugar by half. Also, only went 2 minutes in the microwave.

I took everybody's advice and it came out perfectly. I used golden caster sugar, self-raising flour and 3Tbsp melted butter. I mixed the dry ingredients (same measurements as the recipe) in a bowl and the wet in a jug. I then poured the wet in the bowl, mixed and added chocolate chunks and 1tsp peanut butter. I microwaved it in the bowl for 1.50min. Great with vanilla ice cream. This method 5*.

Have registered just to say how awful this recipe is! Save the ingredients and spend your time and money making a proper cake! Was like eating chocolate rubber, in fact chocolate rubber would probably taste better!

I've been telling everyone. It's the egg. Don't use it.
