Chocolate Peanut Butter Cupcake

My Son is in compulsory boarding school for this term and he is having tough time with the food there. He comes home every weekend so I wanted to give him surprise treat with all his favourite food. Cake is one of his big time favourite. I tried this for him. Entire weekend he was enjoying it. This came out extremely well. Even my husband who is not a big fan of chocolate cake enjoyed it
