Preheat oven 170C / 350F / Gas 4

Using a muffin tin or Yorkshire Pudding tin use 12 muffin cases (all sorts of nice ones around) 

Cream Butter & Sugar until light and fluffy

Add 1 egg at a time making sure it doesn't curdle (if it does add some of the flour)

Add Lemon Zest and flour, mix well

Finally add lemon juice and milk

Spoon equally into 12 muffin cakes and bake for approx. 20-25 minutes

Next make the icing by creaming the butter with the icing sugar until very light and fluffy - probably better with electric mixer

When the cupcakes are totally cold spoon or pipe on the icing

Decorate how you like - there are lots of lovely bits to decorate in most supermarkets
