Chocolate Shortbread - cooking recipe

Ingredients

1 cup (2 sticks) unsalted butter, softened
1 cup powdered sugar
2 tsp vanilla extract
1 1/4 cups flour
1/2 cup rice flour
1/3 cup unsweetened cocoa powder
1/4 cup sugar crystals

Preparation

Preheat the oven to 325\u00b0F. Line 2 large baking pans with parchment paper.
Beat butter, powdered sugar and vanilla extract in a large bowl with an electric mixer until light and fluffy. Sifted flours and cocoa powder into a medium bowl. Beat into butter mixture in 2 batches. Turn the dough onto a lightly floured surface and knead lightly for 5 mins.
Divide mixture into 6 equal portions. Use your hands to press each dough portion into a 5-inch round. Mark each shortbread round into 6 wedges with the back of a large knife, then prick with a fork. Use your fingertips to pinch the edges of the rounds. Sprinkle top with the sugar crystals.
Bake for about 45 mins or until cooked through. Cool completely in pan on a wire rack.
