Custard powder biscuits

I have 2 biscuit recipes that I love - for different reasons.  This recipe, which uses custard powder and no eggs, creates a deliciously soft dough and a biscuit with soft insides - perfect for jam drops or larger biscuits!

250g butter
125g icing sugar
1 tsp vanilla essence
2 cups plain flour
1/2 cup custard powder
2 tbs milk

All in the stand mixer (using the paddle attachment)/using hand beaters if they are strong enough

Cream butter and sugar, add vanilla
Beat in custard powder, flour and milk until a soft dough forms
Turn it out onto your bench (either floured or otherwise greaseproof'ed - paper, nordicware baking sheet etc) and bring together into a ball, which you wrap in cling film and refrigerate for an hour.

Make whatever biscuit shape you like, which will also determine the cooking time.

I like interesting jam in my jam drops - I made half with orange marmalade and half with blueberry jam, and baked for 25 minutes at 180 degrees.
