[Baking] Chocolate cake w/ Chocolate filling and MMF (Marshmellowfondant)

Thank you so much everybody that have been voting for me! 

Well, since there was so many people that enjoyed my cake, and wanted the recipe, I have decided to republish the recipe only that this time it will be in English! 

Anyway! ~ Ingredients:

Ingredients For the cake:
60g melted butter
4 dl milk
5 dl flour
2,5 dl sugar
2 tablespoons baking cocoa
1 teaspoon baking soda

Filling:
130g melted butter
400g icing sugar
2 teaspoons vanilla sugar
2 teaspoons coffee
2 tablespoons baking cocoa

MMF:
300 g Marshmellow
3 tablespoons water
500g icing sugar

To create a land pan, simply double cake recipe.


Procedure:

The cake: 
1 Mix all dry ingredients in a bowl and add the melted butter and milk.
2 mix until a smooth batter and pour into the baking pan you want.
3 Bake in oven at 175 Celsius degrees for about 30 minutes.

Note: The cooking time varies from oven to oven. Use a cake pop to be sure!

Procedure for filling: 
1 Mix the dry in a bowl.
2 Add the melted butter and boiled coffee.
3 Stir until well mixed and place in the refrigerator until the filling has been cold but not hard!

Procedure on MMF:
1 Take 300 g marshmellow in a bowl and add 3 tablespoons of water.
2 Insert in the micro until they are inflated.
NOTE: You must be looking at because this can go fast!
3 When the marshmallow is finished, stir and add the icing sugar until you manage to make a "lump" of it. If necessary, have the food coloring if you want color on MMF.
4 Wrap it in plastic and leave it room temperature.

If you make the MMF the day before or got some left overs you want to use later, just place it in the refrigerator. Just remember to let it stay in room temperature in some minutes before using.

How to assemble: 
1 When the cake has cooled, divide it into as many layers as you want.
2 Place cake layers and fillings layers by layers until you run out of cake, but have also a layer of filling on top. This will be used for "glue" for MMF.
3 Roll out the MMF as thin as you want without tearing. Roll it rather too large than too small in circumference!
4. By eye, find the midpoint of the cake and MMF, adding MMF over cake. Remember that it will be a little beyond the sides, since we intend to roll down the MMF on the sides of the cake too.
5 Start by stroking gently on top to make it flat and get out the bubbles.
6 Hold the MMF that is hanging down the side and gently stroke from the top to down on the side. Remember to not hold back, because then it will rips the MMF.
By doing this, the transition from the top to down tier pages much finer, smoother and no air bubbles underneath.
7 After you have done this around the cake, take a knife to cut the bottom of the cake so you get off the MMF that is left over.
8 The rest of MMF can be used to create decorations, or put in the fridge and save it for the next cake. Just remember to leave it on the counter for a little while before use. (Like I said earlier)

And volla, the cake is done! Enjoy! :)
