Prepare your oven and baking sheets. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
Mix the dry ingredients. In a medium bowl, whisk together the flour, baking soda, cinnamon, ginger, nutmeg, cloves, and salt until well combined.
Combine wet ingredients. In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth. Add the pumpkin puree, egg, and vanilla extract, and whisk until thoroughly incorporated.
Create the cookie dough. Gradually add the dry ingredients to the wet ingredients, stirring with a rubber spatula just until combined. Be careful not to overmix; stop when you no longer see flour streaks.
Fold in the chips. Gently fold in the white chocolate chips until evenly distributed throughout the dough.
Chill the dough. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (this helps prevent spreading and enhances flavor).
Scoop the cookies. Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Add extra chips on top. Press a few additional white chocolate chips onto the tops of each cookie dough ball for a bakery-style appearance.
Bake until just set. Bake for 10-12 minutes, or until the edges are set but the centers still look slightly underdone (they’ll continue cooking on the hot baking sheet).
Let them cool properly. Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
