Seal the jar, tie it with a ribbon, and attach a gift card with this simple recipe: "Preheat oven to 350°. Have ready 2 nonstick baking sheets. Using a mixer or wooden spoon, cream together 3/4 cup (1 1/2 sticks) softened butter with the brown sugar in the jar. Add 2 eggs, mixing them in one at a time. Add 1 1/2 teaspoon vanilla extract and blend. Add the remaining ingredients from the jar and mix just until all the flour is absorbed. Use 2 tablespoon cookie dough for each cookie, and space them an inch apart on the baking sheets. Bake until golden brown, 12 to 15 minutes. Cool on wire racks. Makes about 24 cookies."
