Special equipment: 12 bun muffin pan, lined with muffin papers
Take everything you need out of the fridge in time to get to room temperature – and this makes a huge difference to the lightness of the cupcakes later – and preheat the oven to 400 degrees F.
Put all of the ingredients for the cupcakes except for the milk into a food processor and blitz until smooth. Pulse while adding the milk down the funnel, to make a smooth dropping consistency.
Divide the mixture between a 12-bun muffin tin lined with muffin papers, and bake in the oven for 15 to 20 minutes. They should have risen and be golden on top. Let them cool a little in their tins on a rack, and then take them carefully out of the tin to cool in their papers, still on the wire rack.
Ice with Royal Icing.
Royal Icing:
Combine the egg whites and confectioners’ sugar in a medium-size mixing bowl and whip with an electric mixer on medium speed until opaque and shiny, about 5 minutes. Whisk in the lemon juice, this will thin out the icing. Beat for another couple of minutes until you reach the right spreading consistency for the cupcakes.
