First heat the oven to 180 degrees and grease 2 cake tins.

Then sift the flour, baking powder, bicarbonate soda. Whilst mixing them all together gradually add the sugar.

Next pour in the condensed milk, melted butter, vanilla extract, white wine vinegar and water. Mix well until you have smooth mixture.

Once all the ingredients are combined together pour an equal amount of cake batter into the two cake tins until all of the mixture has gone.

Finally put the two tins in the oven for 25 - 30 minutes.
