Bella Cupcakes: Tutorial 1M wilton tip:- 1. Start from the middle and pipe a small amount of buttercream into the centre. 2. Slowly work your way around going anti-clockwise until you reach the outer edge of your cupcake. Remember to apply even pressure to your pipping bag, this insures an even swirl all the way around. 3. Finish of with a decoration where the swirl ends.
