To prepare a wheat free shortbread rice recipe, you will need: 1 cup shortening, 1/2 cup sugar, 1 tablespoon vanilla, and 1 teaspoon salt. Preheat the oven to 375 degrees F (190 degrees C) and prepare your oven rack to rack 12 inches from the heat source. Line the bottom of an 8 x 8-inch baking pan with foil and set aside. In the bowl of your stand mixer, cream the butter with the sugar and vanilla until light and fluffy. Add the egg and beat until the mixture reaches stiff peaks. Gradually add the flour, beating after each addition until just combined. Pour the batter into the prepared pan and spread it evenly. Bake for 25 to 30 minutes or until golden brown. Serve warm with ice cream or whipped cream.
