I have been known to eat these pumpkin spice bars without the cream cheese frosting even, but they are even better topped. These pumpkin bars are very light like cake since they start with a box mix, but they are thinner making them more like a bar.

These pumpkin spice bars are so moist and flavorful, and the cream cheese frosting really gives it that extra bit of sweetness. I even used a little bit of pumpkin spice sprinkled on top of the cream cheese frosting for a boost of flavor and a bit of color to the bars.

I’m going to let you in on a little secret too. This recipe is SO very versatile. You can use just about any cake mix and any can of filling to make the variation on these fit for any season. My personal favorite is using lemon cake mix and lemon pie filling. The lemon bars are so refreshing in the summertime!
