1 cup sugar
1 tbsp baking powder
1 tsp vanilla sugar/ essence
3/4 cup oil
1/4 cup milk
1 and a quarter cup flour
1 to 2 tbsp cocoa powder
Beat the eggs, sugar and baking powder at high speed until fluffy, then reduce the speed to low then add the oil and the milk, continue beating for a minute. Then still at low add the flour in two additions mixing well after each addition.
Stop the mixer and scrape out the sides and bottom and continue mixing.
Next take 1 cup of the batter and add 1 to 2 tbsp of cocoa powder and mix well.
Now pour the plain batter in a greased baking pan and tap the pan so the batter sits evenly. Then add the cocoa batter
over the plain batter and Spread the cocoa batter, then tap the pan. Now take a butter knife and gently cut through cake batter to gently kind of mix the two batters together. Bake the cake in a 350 degrees oven for about 30 to 40 minutes, or until toothpick inserted comes out clean.
Let the cake completely cool before cutting.
