Robin likes to bake cupcakes for friends and to make her puppy North happy. Once Robin ate four cupcakes with chocolate sauce and twice as many cupcakes with buttercream frosting on her own. How many cupcakes did Robin eat?
Robin ate twice as many buttercream cupcakes as chocolate sauce cupcakes, or 2 * 4 = <<2*4=8>>8.
So in total she ate 4 + 8 = <<4+8=12>>12 cupcakes.
