Look at the freshly baked cupcakes, no cracks, flattish and smooth. Adding 1 tsp of baking powder made the batter rise to just the level I wanted. I still think the muffin cases I'm using are too big. So I'm gonna try baking cupcakes in the smaller cup cases I just bought, without adding baking powder; they should fill up nicely too.
Anyway, this blue-themed arrangement was done for little Ian, who arrived on 15 March, 2 days before little Valerie. None of the Tays is in London to eat the cupcakes though. The creamy looking topping is melted white chocolate.
