Chocolate Covered Strawberry Cupcakes Chocolate cupcakes with a Nutella filling and strawberry frosting, topped with a chocolate covered strawberry. Lemon cupcakes with a white chocolate 'bubbles' decoration. The idea for the decorations came from The Lone Baker . To make them you pour melted chocolate onto clean bubble wrap and leave to set. Once the chocolate has set remove it from the bubble wrap and you are left with the imprint of the bubbles on the chocolate!
