I use my Thermomix to make the batter but you certainly don't need one to make these biscuits. There are also many variations you can try. The recipe below is for the plain vanilla ones, however you can add about 40-50g of cocoa to make chocolate ones; or sprinkle with chopped nuts and other toppings as seen in picture at the bottom of this post for more variety.
Custard Biscuits
Makes approx. 30
250g unsalted butter (softened is better if not using a Thermomix)
50g (1/2 cup) pure icing sugar plus extra for dusting
1 teaspoon vanilla extract
210g (1 3/4 cups) plain flour
50g (1/2 cup) custard powder
1. Preheat oven to 180 degrees Celcius fan forced and line 2 baking trays with baking paper. If you don't have two trays, you can just bake alternative batches using same tray once it has cooled slightly.
2. Place butter, sugar and vanilla into Thermomix and mix for 20 seconds at speed 5. If using a food processor, process for a couple of minutes or until ingredients are well combined.
3. Add flour and custard powder into Thermomix bowl and knead for 30 seconds. If using a food processor, pulse until just combined. If you over mix, the biscuits may not have the soft texture that you are after.
4. Roll tablespoons of the mixture into balls and place on prepared trays. I use a measuring tablespoon to try and get them all roughly the same size. Then using a small fork dipped in a touch of flour (so as not to stick), slightly flatten each ball. This will give the biscuits a lovely ridged design.
5. Bake for 10-12 minutes or until slightly golden. Once removed from oven, leave them on tray to cool or wait 5-10 minutes and then transfer to a wire rack to cool completely. If you try to move them too soon after taking out of the oven, they will break. They harden a little as they cool.
6. Finally, dust them with a little icing sugar to make them look pretty :)
