Kirstie Allsopp's Smarties cupcakes

The kids are going to love making these quick Smarties cupcakes ready in just 20 minutes, four simple steps 

These easy Smarties cupcakes are made by Kirstie Allsopp as demonstrated in the video below. These cupcakes are made with cocoa powder and condensed milk. Kirstie says the condensed milk creates “a smooth batter and gives the cupcakes a moist finish.” Pipe a swirl of fudgy chocolate buttercream and finish with plenty of Smarties.

Let your imagination run wild with toppings for your cupcakes - there are loads of great decorations in the shops or use chopped nuts, banana chips, curls of chocolate or silver balls. You could even use other chocolate bars too like chocolate buttons or M&M’s.
