To make pecan shortbread bars, pulse pecans in a food processor until finely chopped. Blend sugar, flour, butter and salt, and add the pulsed pecans. Press the dough into the bottom of an 8-inch pan with aluminium foil, and bake in a preheated oven at 350 degrees Fahrenheit until lightly golden. Allow it to cool in the pan for five minutes before transferring the shortbread to a cutting board to cut it into 18 bars.
Ingredients for these pecan shortbread bars include 1 cup of pecan halves, 1 cup of all-purpose flour, 3/4 cup of confectioner's sugar, 1/2 cup of cold unsalted butter and 1/4 teaspoon of salt. It yields 18 pecan shortbread bars and requires about one hour and 30 minutes of preparation and cooking time. An alternative recipe adds vanilla extract and almond extract to the ingredients.
Start by preheating the oven to 350 degrees Fahrenheit and lining the 8-inch baking pan with aluminium foil, leaving an overhang on all sides. Use a food processor to pulse the pecans before transferring them to a bowl. Use the processor to blend the butter, sugar, salt and flour until the mixture forms moist clumps. Add the pecans before pulsing two or three more times.
Evenly press the dough into the baking pan, and use a floured fork to prick the dough after every 1/2 inch. Bake it for about 35 minutes or until lightly golden. Remove the pan from the oven, and allow it to cool before using the overhanging foil to lift the shortbread from the pan onto the cutting board to cut it into bars.
