These are one of my favourite biscuits…they never last long in our house and good to make if you have some egg yolks to use up.
Vanilla Custard Kisses
125g butter
1/2 cup caster sugar
2 egg yolks
2 tsp vanilla
1/3 cup custard powder
3/4 cup plain flour
3/4 cup self-raising flour
Vanilla Cream:
40g butter, softened
2/3 cup icing sugar
1 tsp vanilla
1 tbs milk
Preheat oven to moderate. Line two biscuit trays with baking paper. Using electric beaters, beat butter and sugar in bowl until mixture is light and creamy. Add the egg yolks, one at a time, beating thoroughly after each addition. Add vanilla, beat until combined.
Using a metal spoon, fold in sifted custard powder and flours. Stir until ingredients are just combined and the mixture is almost smooth. Press mixture together with finger-tips to form a soft dough.
Roll 1 level tablespoon of mixture at a time into balls. Arrange on trays about 5cm apart. Flatten lightly to 2.5cm rounds. Bake 12 minutes or until biscuits are golden.
To make Vanilla Cream: Beat butter and essence in small bowl with a wooden spoon until smooth. Add sifted icing sugar and milk gradually; stir until well combined and mixture is smooth.
Stand biscuits on trays for 5 minutes; transfer to a wire rack to cool.
Spread half the biscuits with filling and sandwich together with remaining biscuits.
