Ingredients
Equipment
Method
Preheat and prep pan
- Preheat the oven to 350F and grease a 9x13 baking pan with a thin, even coating so the bars release cleanly.
Make the cake mix crust
- Combine the yellow cake mix, melted unsalted butter, and egg, stirring just until a thick dough forms.
- Press the crust firmly into the bottom of the pan so it forms an even, compact layer.
Make the gooey pumpkin filling
- Beat the cream cheese until smooth, scraping the sides as needed to remove lumps.
- Add the pumpkin puree, eggs, and vanilla extract, then beat until fully combined.
- Beat in the second batch of melted unsalted butter until the filling looks glossy and uniform.
- Add the powdered sugar, pumpkin pie spice, and cinnamon, then beat until smooth and thick enough to pour.
Bake and finish
- Pour the gooey filling over the crust and spread it to the corners.
- Bake for 40-45 minutes at 350F, until the edges are set but the center is slightly jiggly—do not overbake.
- Cool completely on a rack before cutting to keep the gooey texture intact.
- Dust heavily with extra powdered sugar, then cut into bars.
Notes
For clean slices, cool completely (at least 2 hours) so the center can set to that controlled jiggle. Store airtight in the refrigerator up to 5 days; freezer yes—freeze bars up to 2 months and thaw in the fridge. For a lighter option, use low-fat cream cheese and reduce powdered sugar by about 1/4 cup while keeping the texture stable.
