• Preheat oven to 375℉. Line two baking sheets with parchment paper or a silicone baking mat. Gather your ingredients so that you have everything close at hand on the counter or table.
• Using a nut chopper or a knife, coarsely chop the pecans.

Prepare the Cookie Dough

• In a large mixing bowl, cream together the room temperature butter, vegetable oil, granulated sugar, and powdered sugar.
• Beat in the large egg and then the vanilla and butter extracts.
• Using a small bowl, combine the all-purpose flour, baking soda, cream of tartar, and salt.
• Add to the creamed mixture, and mix until combined. (It may be necessary to add more flour to create a firm dough, 1 tablespoon at a time, up to 1/3 cup.)
• Stir in the chopped pecans.

Prepare Cookies for Baking

• Measure out 1/2 cup of granulated sugar and place in a small bowl.
• Roll the cookie dough into walnut-sized balls and then roll them in the bowl of sugar to coat.
• Place each ball on the baking sheet, about 2 inches apart. Using a flat bottomed cup or glass, gently press each ball to flatten.
• Bake in a preheated oven for 10 -12 minutes, until edges of cookies are just barely golden. Cool on a wire rack. This recipe will make 2 dozen cookies.
