Have a look below at The Quintessential Orange Cupcake Recipe
125 g sugar
2 medium sized eggs - beat until white
110 g wheat flour (not self raising) - sieved inn
1 ts baking powder
125 g butter - melted - add to mix
1 small pot of orange/apricot youghurt (not fat free aspartame style youghurt, and not frenc "set" either)
1 table spoon orange/apricot marmelade (optional)
2 table spoons orange juice
Bake on 180 degrees for 25-30 minutes. (gasmark 4?)
This is a delicious moist cupcake.
If you ice it, use just icing sugar, water and 1 or 2 drops of lemon essence
I often use any combination of youghurt or jam, so blueberry, or rasberry, anything is possible really. But then I will use milk rather than orange juice.
I should add, for a more "grown up" cupcake, I use a cream cheese frosting (with a drop of lemon essence), with a generous helping of frosting, "swirled up", and decorated with silver balls, for example.
But these ones can also be topped with a chocolate ganache, with orange decorations.
The above recipe makes 12 cupcakes
