Haven't made these yet, but they look irresistable and so tempting. If you get to bake them before me let me know what you think. Perfect afternoon tea fare. This recipe comes from Family Circle's Biscuit and Slices book.
Preheat oven to 180°C Brush two 32 x 28cm biscuit trays with melted butter. Line base with paper; grease paper.
Using electric beaters, beat butter and sugar in a small mixing bowl until mixture is light and creamy. Add th egg yolks one at a time, beating thoroughly after each addition. Add vanilla essence; beat until combined.
Transfer mixture to a large mixing bowl. 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 fingertips to form a smooth dough.
Roll 1 level teaspoon of mixture at a time into bowls. Arrange on prepared trays about 5cm apart. Flatten lightly with base of glass to 2.5cm rounds. Bake 12 minutes or until biscuits are golden.
TO MAKE VANILLA CREAM:
Beat butter and essence in a small bowl with a wooden spoon until smooth. Add sugar and milk gradually, stir until well combined and mixture is smooth.
Stand biscuits on trays for 5 mins, transfer to a wire rack to cool. Spread half the biscuits with filling and sandwich together with remaining biscuits. If you like you can dust biscuits with icing sugar as well.
