1-First Step: Begin by preheating your oven to 350°F and lining two baking sheets with parchment paper. This prevents the cookies from sticking and makes cleanup easier. In a large mixing bowl, combine 2 cups of canned pumpkin puree, 1 cup of vegetable oil, 2 eggs, and 2 cups of sugar. Beat these wet ingredients together until smooth and well combined. The mixture should have a uniform orange color and creamy consistency.

2-Second Step: In a separate medium bowl, whisk together the dry ingredients: 4 cups of flour, 2 teaspoons of baking powder, 2 teaspoons of cinnamon, 1 teaspoon of baking soda, 1 teaspoon of salt, ½ teaspoon of nutmeg, and ½ teaspoon of ginger. This step ensures that the spices and leavening agents are evenly distributed throughout the flour, which helps the cookies rise properly and have consistent flavor.

3-Third Step: Gradually add the dry ingredients to the wet pumpkin mixture, stirring gently after each addition. Be careful not to overmix, as this can make the cookies tough. Stop mixing as soon as no flour streaks remain visible. The batter will be thick and scoopable, with a lovely orange speckled appearance from the spices. This is the perfect consistency for Pumpkin Whoopie Pies that hold their shape while baking.

4-Fourth Step: Using a ¼-cup measuring scoop or two spoons, drop mounds of batter onto the prepared baking sheets, spacing them about 2 inches apart. These cookies will spread slightly during baking, so adequate space prevents them from merging together. For uniform pies, try to make all the mounds the same size. You should get approximately 24 cookies, which will make 12 completed Pumpkin Whoopie Pies.

5-Fifth Step: Bake the cookies at 350°F for 12-15 minutes, or until they are set and spring back when lightly touched in the center. The tops should have a slight matte appearance rather than looking wet or shiny. Rotate the baking sheets halfway through the baking time to ensure even cooking. Watch closely near the end of the baking time, as overbaking can result in dry Pumpkin Whoopie Pies instead of moist, tender ones.

6-Sixth Step: Remove the baking sheets from the oven and let the cookies cool on the pans for about 5 minutes. This brief resting period allows them to firm up slightly, making them easier to move without breaking. Then, transfer the cookies to a wire rack to cool completely. Cooling them completely before filling is crucial, as warm cookies will cause the frosting to melt and slide off.

7-Seventh Step: While the Pumpkin Whoopie Pies are cooling, prepare the creamy filling. In a medium bowl, beat 8 ounces of softened cream cheese and ½ cup of butter together until smooth and creamy. This process is easier if both ingredients are at room temperature, so consider taking them out of the refrigerator about 30 minutes before you begin baking.

8-Eighth Step: Gradually add 4 cups of powdered sugar to the cream cheese mixture, beating well after each addition. This helps prevent a cloud of sugar dust and ensures a smooth frosting. Once all the sugar is incorporated, add 1 teaspoon of vanilla extract and beat for another 2-3 minutes until the filling is light, fluffy, and spreadable. The frosting should hold its shape but still be easy to spread.

9-Final Step: Once the cookies are completely cool, it’s time to assemble your Pumpkin Whoopie Pies. Pair up the cookies by size, matching similar shapes together. Spread or pipe about 2-3 tablespoons of the cream cheese filling onto the flat side of one cookie, then gently press another cookie on top to create a sandwich. Repeat with the remaining cookies and filling. For best results, serve the assembled pies within a few hours, or store them properly to maintain freshness.
