Nikki - the recipe calls for apple pie spice and I had none ........ I had to run to Walmart so I haven't even stirred up the dough yet.
Here's the recipe from MY BAKING ADDICTION - a great site.
Apple Peanut Butter Cookies
Yield: about 3 dozen cookies
Cook Time: 10 minutes @ 375*
1/2 cup butter flavored shortening
1/2 cup creamy peanut butter
1/2 cup granulated sugar
1/2 cup packed light brown sugar
1 large egg
1/2 teaspoon pure vanilla extract
1-1/2 cups Gold Medal all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1/2 teaspoon www.mybakingaddiction.com/apple-pie-spice/" target="_blank">homemade apple pie spice 
1/2 cup grated peeled apple
1. Preheat oven to 375°F. Line a baking sheet with parchment.
2. In a large bowl with an electric mixer, cream the shortening,
peanut butter and sugars until light and fluffy, about 3 minutes.
Beat in egg and vanilla. In a medium bowl, combine flour, baking soda,
salt and homemade apple pie spice. Gradually add the dry ingredients
to creamed mixture, mixing until well combined. Stir in grated apple.
3. Drop by rounded tablespoonfuls 2 in. apart onto prepared baking
sheet. Bake in preheated oven for 10-12 minutes or until golden
brown. Cool for 5 minutes before removing to wire racks.
- Depending upon the type of apples you use, you may end up with a
great deal of liquid after grating the apples. I suggest using only
the grated apples, not the liquid that is produced. If necessary,
lightly squeeze the apples to release any excess juice before adding
them to the batter.
- If you want a little crunch, feel free to substitute crunchy peanut
butter for the creamy.
