Prepare The Brown Butter: In a medium saucepan over medium heat, melt the butter, stirring constantly. Continue cooking until the butter turns a deep golden brown and develops a nutty aroma—about 5-7 minutes. Remove from heat and let it cool slightly.
Mix Wet Ingredients: In a large mixing bowl, add the brown butter, granulated sugar, and brown sugar. Beat with an electric mixer until smooth and creamy. Add the pumpkin puree, egg, and vanilla extract, mixing until fully combined.
Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, cream of tartar, salt, cinnamon, ginger, and nutmeg. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Avoid overmixing.
Chill the Dough: Cover the dough with plastic wrap and refrigerate for at least 1 hour, or up to 24 hours. Chilling helps to develop the flavors and makes the dough easier to handle.
Preheat Oven: When ready to bake, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Roll the Cookies: In a small bowl, mix the granulated sugar and cinnamon for rolling. Scoop about 1 tablespoon of dough and roll it into a ball. Roll each ball in the cinnamon-sugar mixture, making sure it’s coated well.
Bake: Place the dough balls on the prepared baking sheet, spaced about 2 inches apart. Bake for 10-12 minutes, or until the edges are set but the centers are still soft. Let them sit on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Serve and Enjoy: Once cooled, these cookies are perfect for sharing with family and friends or enjoying with a warm beverage!
