just attempted our first cake-bake following a recipe, however we accidentally put all of our butter into the cake mix, leaving none for the icing. in a moment of inspiration and desperation, we substituted the butter for margerine. we followed all the instructions from the recipe as well as we could. the cake has come out fine, but now we have a problem with the taste of the icing. it tastes like margerine. it's also a bit too runny and we've run out of icing sugar. does anyone have any suggestions as to how we could alter the taste of the icing and possibly thicken it's consistency?
it's a chocolate cake with chocolate icing. the icing is already pretty sweet, i don't think it needs to be any sweeter, at the moment the cake halves are cooling and the icing is in the fridge (trying to make it thicker)
