I’d never tried the swirl. It seems the perfect recipe to end up on Pinterest Fail. However, sometimes you’ve got to mix it up!
I stuffed a bag with chocolate icing on one side and peanut butter on the other. It worked out ok but wasn’t perfect. My main issue wasn’t in separating the flavors but that the chocolate and peanut butter icings were different consistencies. You can see in the photos how they didn’t behave the same, the peanut butter was not as smooth (probably not a frosting best suited to piping).
I later saw someone doing this with three bags (two bags of icing in a third bag with tip), and I will try that method next time! I’ll also make sure my frostings are more similar.
I was fulfilling a birthday cupcake flavor request of peanut butter and chocolate. The swirled icing wasn’t the only chocolate in my peanut butter, the cupcakes themselves were peanut butter with chocolate chips.
