Making Pumpkin Cake Squares is a simple process that yields incredible results. Follow these steps for a delicious treat:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
2. Mix Wet Ingredients: In a large mixing bowl, combine the pumpkin puree, granulated sugar, vegetable oil, eggs, and vanilla extract. Whisk until well blended.
3. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger.
4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid overmixing.
5. Add Nuts: If using, fold in the chopped nuts gently.
6. Pour Batter: Pour the batter into the prepared baking pan, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Remove from the oven and let the cake cool in the pan for 15-20 minutes. Then, transfer to a wire rack to cool completely.
9. Cut into Squares: Once cooled, cut into squares of your desired size.
10. Dust with Powdered Sugar: For an added touch of sweetness, dust the squares with powdered sugar before serving.
