Mix until the chocolate has melted. Allow it to cool.
Add the bloomed gelatine mixture to the remaining amul cream.
Heat it. At first it will be very thick and jelly like.
When it starts heating it will start thinning.
When it starts boiling, add it to the melted chocolate and mix well.
Mix.
Keep on mixing until it is completely incorporated. Place it in fridge until cool.
Whip the cold fresh cream until soft peaks form.

Using a spatula, gently fold the chocolate into the cream without deflating it.
Refrigerate for atleast one hour.
It is so light and delicious.

Vanilla Buttercream:
Salted Butter – 150 g, at room temperature, but a little firm
Icing Sugar – 300 g
Fresh cream – almost 1/3 cup
Vanilla extract – 1 teaspoon

Method:

1. Sift icing sugar a couple of times.  Keep aside.

2. Add the fresh cream into the bowl of your electric mixer. Into that add 1/2 of the icing sugar and beat on low speed until the icing sugar has been incorporated. Beat for one minute, and then add the remaining icing sugar and beat on medium high speed for 3 to 5 minutes until most of the icing sugar has been dissolved in the cream.

3. Add vanilla extract and beat until combined.

4. Add butter a little at a time while beating and beat on medium speed just until all butter has been used up.

5. Now beat just for a minute or two until the frosting becomes creamy and stiff.

6. Do not over beat after this stage or the frosting might curdle.
