Preheat oven to 350°F (175°C). Grease an 8×8-inch baking pan.
In a medium bowl, combine melted butter, light brown sugar, eggs, and vanilla extract. Mix until well combined.
In a separate bowl, combine flour, baking powder, and salt. Gradually add dry ingredients to the wet ingredients, stirring until just combined.
Spread the batter into the prepared pan. In a small bowl, mix together pumpkin, pumpkin pie spice, white sugar, and cinnamon. Drop spoonfuls of the mixture over the blondie batter.
Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Cool before cutting into bars.
