Preheat oven to 350 F. Line baking sheets with parchment paper or silicone baking mats.
In a small mixing bowl, toss together the dry ingredients.
In a stand mixer or larger mixing bowl, cream the butter with both of the sugars. Add the dry ingredients and mix into dough. Mix in the canned pure pumpkin until cookie dough forms. Mix in the white chocolate chips.
(Note: if you want to replace the cinnamon, nutmeg and cloves with 2 tsp pumpkin pie spice, you can do that. Here is my homemade pumpkin pie spice mix.)
Add cookie dough to prepared baking sheet by spoonful, about 2 inches apart.
Bake in preheated oven for 12 to 14 minutes, or until begin to golden to top.
Let cool for a few minutes before serving.
Serve Oatmeal Pumpkin Spice Cookies with White Chocolate Chips for dessert or sweet snack.
