Preheat oven to 350 degrees

Place the butter, powdered sugar and vanilla in a bowl and beat with an electric mixer until light and fluffy.

Stir in the sifted flour and cornstarch until combined.

Place the mixture in a piping bag fitted with a fluted tip. Pipe 1in rounds onto a baking sheet linded with parchment paper, allowing room to spread.

Bake for 12 - 14 minutes or until golden. Cool on a tray (not on a rack, that will make it hard to pick up the delicate cookie).

Place all ingredients in a sauce pan and turn on very low heat.

Stir for 25-30 minutes or until thick and pale golden. Allow to cool. Eat with a big spoon.
