Chocolate cupcakes with nutella cloud frosting

It was my dad's birthday past Tuesday and as a family affair. Unfortunately it was not a celebration we expected it be.my mousse cake turned out so bad I wanted to throw it away although everyone who ate it said it was delicious.luckily I had cupcakes to back up the disaster.but I am still not satisfied so I told dad I will make him another cake and I will stick to 'normal' cakes.

 So what went wrong to my caramel rum raisins mousse cake? :

 1. My gelatin didn't dissolve properly even after mixing it with hot liquid.jinx! So both layers of mousse didn't set!
 2. My caramel glaze was very jelly like,not sure if that was meant to like that but it happen.not much of a glaze.
 3. My small was shallow.no height at all.I thought it was alright but when I removed it from the ring,it was soo shallow.

 Anyway, the nutella cupcakes were a success minus the coffee maybe because I made a really thick coffee for it and therefore the cupcakes had a hint of bitterness to it. The cupcake batter wasn't enough to fill 24 mini cupcakes so I made another batch of cupcake batter but without coffee this time.I got about 40cupcakes altogether.as for the nutella frosting,I didn't have to double the amount up for two batches of cupcakes which was good.

I used the exact recipe I got from Rosie of Sweetapolita minus the coffee for one batch.I replaced it with boiled water.
Overall, I preferred the cupcakes without coffee.

The horrible birthday cake!:(
