Making Soft Pumpkin Cookies with Cinnamon Frosting is a straightforward process. Follow these steps for the best results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
2. Combine Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, baking powder, cinnamon, nutmeg, ginger, and salt. Set aside.
3. Mix Wet Ingredients: In a large bowl, combine the pumpkin puree, granulated sugar, brown sugar, vegetable oil, egg, and vanilla extract. Mix until evenly blended.
4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
5. Scoop the Dough: Using a cookie scoop or tablespoons, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
6. Bake Cookies: Bake in the preheated oven for 12-15 minutes or until the cookies are lightly golden and set in the center. A toothpick inserted should come out clean.
7. Cool Cookies: Remove the baking sheets from the oven and allow the cookies to cool on the sheets for about 5 minutes. Then, transfer them to wire racks to cool completely.
8. Prepare the Frosting: While the cookies cool, prepare the cinnamon frosting. In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, cinnamon, and vanilla. Mix until smooth, adding milk as needed to reach the desired consistency.
9. Frost the Cookies: Once the cookies are completely cooled, spread a generous amount of frosting on top of each cookie using a spatula or a piping bag for a decorative touch.
10. Serve: Enjoy your Soft Pumpkin Cookies with Cinnamon Frosting immediately, or store them in an airtight container for later enjoyment.
