Spread the oats and walnuts together on an ungreased baking sheet for 5 to 7 minutes, or until lightly browned and set aside.
In a small saucepan, combine the raisins and 1 cup water. Bring to a simmer over low heat and cook until the raisins are plumped about 10 minutes. Drain, discard the liquid, and set aside.
In a large mixing bowl, beat the sugar, apple butter, eggs, oil, and vanilla with an electric mixer until light and fluffy, about 5 minutes.
In another bowl, sift together the flour, baking soda, baking powder, salt, cinnamon, and cloves. Stir the flour mixture into the apple butter mixture with a spoon.
Stir in the reserved oats, nuts, and raisins, and mix well.
Drop by rounded teaspoonfuls, about 2 inches apart on baking sheets. Bake 8 to 10 minutes, or until lightly browned but still slightly soft. Once cool to the touch, transfer to a cooling rack to cool.
Notes
You can also make these cookies large, using a 2-tablespoon scoop. To do so, you'll want to extend the baking time by a few minutes.
