Pumpkin Snickerdoodle Blondies

"Soft pumpkin bars, cinnamon-sugary snickerdoodles, and buttery blondies rolled into one easy, no-mixer recipe. The bars are super soft, moist, and full of robust pumpkin flavor. The cinnamon-sugar topping lends an awesome texture contrast to the density the pumpkin creates. They’re dense like blondies, rather than cakey or light. They’re for those of us who relish a thick, fudgy texture. If you can resist, they taste better on the second day after the flavors have married. As a bonus, the bars get softer and moister on the second and third day, but I doubt they’ll last that long...."
