Pour in ⅓ of heavy cream in a microwave safe bowl and heat for 1 minute. Take out of the microwave and crumble in 4 pieces of ChocNut. Mix the ChocNut and hot cream until it's fully incorporated and mixed in. Place back in the microwave for 30 seconds to heat up again.
Take out of the microwave and add in 1 cup of Tablea. Mix well until you get a nice glossy mixture and the chocolate has fully melted into the cream. Leave to cool.
Pour in the remaining chilled 1 cup of heavy cream into a mixing bowl. Using a hand or stand mixer whisk the heavy cream until you see soft peaks. Don't over mix or else it won't have a nice silky Chocolate Mousse texture. Stop mixing once you see the whisk start leaving marks. It's better to under whisk than to over whisk in this recipe.
Reserve ½ cup of the whipped cream and place in the refrigerator until needed.
Add in a big spoon of whipped cream to the melted chocolate mixture and fold it in slowly. You don't have to mix it fully at this point. It's okay to have some cream flecks through it. This step just helps lighten the cream making it easier to add to the whipped cream.
Add ⅓ of the lightened chocolate mixture to the whipped cream. Fold it in gently. When most of it is mixed in add the next third of the mixture and fold gently again. Then add in the last third of the chocolate and fold it in slowly.
Keep going until you no longer see any white of the whipped cream. When it starts looking like Chocolate Mousse stop mixing.
Take out 4 small bowls and crumble 1 ChocNut candy in each of the bottom of the cups. Then equally divide the Chocolate Mousse into each serving bowl. Place in the refrigerator to chill for at least 2 hours.
To serve top each serving with the reserved whipped cream and top with more ChocNut candy.
