Preparation method:

1. Preheat the oven to 180C/350F and line 16-hole muffin tin with paper cases.

3. Whisk the eggs, egg whites, vanilla extract, melted butter, oil, milk and pudding. 

4. Combine these two mixtures using metal spatula until smooth. 

5. Spoon the mixture into paper cases to 2/3 full and bake for 20 minutes or until a skewer inserted         into one of the cakes comes out clean. Leave onto wire rack to cool. 

6. Preparing butter cream: Whisk two egg whites with sugar, using electric whisk into a mixing               bowl. Whisk until sugar dissolves. 

7. Stir in butter and whisk until mixture is well combined. Melt chocolate over steam, and set                   aside, for 5 minutes. 

8. Finally add vanilla extract and melted chocolate. Whisk until is completely combined. 

9. Leave in refrigerator for 20 minutes.
