Let’s make it

Step 1

Mix the dry ingredients well in a large bowl. For better texture, sift the dry ingredients together with a sieve or sifter.

Step 2

Add the eggs, milk, vanilla, and vegetable oil, and mix well. Add the water, and mix it until it has a lot of little bubbles. This batter will be very thin.

Step 3

Pour into two greased 9-inch round baking pans.

Step 4

Bake in a preheated oven at 180°C for 30 minutes (about 20 minutes for a convection oven), or until a cake tester comes out clean. Remember not to over-bake the cake, as it may become really dry and lose all its moisture.

Step 5

Cool the cakes completely, then unmold them.

Step 6

Melt the chocolate by placing it in a double boiler.

Step 7

Mix the sugar and cocoa together in a small bowl, then mix in the water.

Step 8

Stir the sugar/cocoa/water mix into the melted chocolate.

Step 9

Quickly stir in the cream and mix until it has a smooth consistency.

Step 10

Immediately 'frost' the cake with this, making sure that there is quite a bit between the two layers of cake. The cake will need to be refrigerated to harden the fudge, so don't worry about its relatively liquid nature.

Step 11

Serve warm after refrigeration. To serve, slice a piece and microwave it for about 20 seconds. The fudge will melt and soak into the cake. Serve with ice cream if you so desire.
