Reese’s Peanut Butter Cup Cupcakes

| |

I have said it before and will say it again – peanut butter and chocolate were just made to go together.  What was the world like before peanut butter cups were invented?  Wannabite adds Reese’s peanut butter morsels to these chocolate cupcakes which are then topped with peanut butter buttercream.  Everything is right with the world again.
