Chocolate Mousse Brownies
These brownies are insanely good! This recipe was inspired by my chocolate cheesecake mousse and how it was both rich and light. I wanted to bring that same texture to a batch of brownies to balance the dense and chewy texture of the brownie itself and it ended up working so well. To make the mousse, you just make a simple chocolate ganache in a saucepan and melting marshmallows into it. Traditionally, mousse is made with gelatine which is also used in making marshmallows so this does the same job while also adding in a bit of marshmallow yumminess to the mousse!
