Prepare ingredients for the Easy Chocolate Mousse Recipe.
Combine sugar together with 1.5 cups of raspberries. Let it simmer until you get an even texture.
Drain out the liquid from the raspberry mixture by using a sifter. This will get rid of all seeds.
On a steam bath, melt chocolate until it's all creamy. To create a steam bath, fill a pot with water, cover it with a heat resistant bowl and bring the water to boil, melting chocolate in the bowl.
Combine together the chocolate mixture with raspberry sauce.
In a stand up mixer, whisk whipping cream until stiff peak. In small portions, incorporate the whipping cream into the chocolate.
Place mousse into a piping bag. Pipe the mousse into individual cups.
Decorate the tops with the remaining berries or as you wish. Let it refrigerate for a few hours before serving.
