3 tablespoons Nutella
1 egg
2 tablespoons milk
2 tablespoons vegetable oil
3 tablespoons all-purpose flour
3 tablespoons granulated sugar (increase by 2 teaspoons if you want. Some people say this cake is less sweet to their liking.)
1 tablespoon unsweetened cocoa powder
1/4 teaspoon baking powder
Directions:
First, in a mug, add in an egg, milk, vegetable oil, and Nutella. Stir until combined.
Sift in flour & cocoa powder. stir until well mixed.
Now the batter should be pretty liquidy.
And microwave for 1 minute. The power of individual oven is different, so be careful. Then repeat microwaving until the cake is done.

For the plastic mold container you will find them at Phoon huat Bencoolen about 12 each will do and also the chocolate pearl come in small packet.
Make strong kopi in a coffee mug with hot water .about 1/4 liter will do ,
Mix the egg yolk with 100 gm. of sugar till become yellow pale ( we call it blanchir or blanched in kitchen language) , soften the mascarpone and combine with mix egg yolk sugar .
Deep the boudoir cake into the kopi0 one by one and display in the cake 12 plastic container one per mold will do (make sure the coffee is not hot so you burn your finger ) you deep them very quickly if to long will break and that action of deeping in kopi0 should take you few second only to do.
Now you have your container with boudoir kopi0 ready put aside table ,
Whisk the egg white with a pinch of salt make sure the egg white are room temperature , when you see the egg starting to get firm add sugar in two time and keep whipping this operation can be a bit difficult but don't forget this for your love you can do it. if you have kitchenaid machine even better.
Combine slowly the mascarpone mix with the egg white and split all the mixture into the 12 plastic mold . display few chocolate pearl and some cocoa powder , if you don't have cocoa powder you can use milo powder also nice .

Beat butter, sugar, salt and vanilla till creamy.
Add in egg yolk and mix till well incorporated.
Add in sifted flour and mix till incorporated.
Dough needs to be refrigerated for a few hours or overnight if not will be too soft to work with.
I roll between 2 pc of baking paper and freeze for 20 mins l (if u dun want to wait overnight) will be easier to cut out the shapes. I dust the moulds with corn flour to prevent sticking.
I use the red hearts sprinkles which I bought from phoon huat at $3.15 and put at the ribbon before baking. The nose is yellow sprinkles.
Bake in the preheated oven at 140 degrees for 18 mins. Depends on the thickness of the cookies. You can try at a lower temperature so the cookies will not brown too much.
After cookies cooled. I use melted baking chocolate and piped the eyes and whiskers.
