Mac in the Back's Shortbread

INGREDIENTS:

1 1/4 cup flour
1/2 cup caster sugar
1/2 cup unsalted butter
1/2 cup rice flour
1/4 tsp baking powder
Pinch of salt

DIRECTIONS:

Preheat oven to 325F. Cream butter and sugar together until fluffy. Stir in the two flours, baking powder and salt. Press mixture into a greased 8-inch cake tin. Smooth out the top, and prick over the surface with a fork. For easier cutting after it's baked, score the dough into 8 slices before putting in the oven. Bake for 45-45 minutes until golden brown.
