Pumpkin Spice Whoopie Pies

Preheat the oven to 350°F (175°C). In a large bowl, mix together the pumpkin puree, vegetable oil, brown sugar, granulated sugar, egg, and vanilla extract. In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, salt, cinnamon, ground ginger, and ground cloves. Gradually add the dry ingredients to the wet ingredients, mixing until well combined. Drop spoonfuls of the batter onto a baking sheet lined with parchment paper, spacing them about 2 inches apart. Bake for 10-12 minutes, or until the edges are firm and the tops spring back when lightly touched. Remove from the oven and let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. In a mixing bowl, beat together the cream cheese, butter, powdered sugar, and vanilla extract until smooth and creamy. Spread a dollop of the cream cheese filling onto the flat side of one whoopie pie, then sandwich it with another whoopie pie. Repeat with the remaining pies. Let the whoopie pies rest for 30 minutes before serving. Enjoy!
