  • 0.25 tsp ground cloves

Equipment

  • 1 stand mixer

Method
 

Prep and crust
  1. Heat the oven to 325°F. Line a 9x13-inch pan with parchment, leaving an overhang on the long sides for lifting the bars out later.
  2. Stir the graham cracker crumbs, granulated sugar, melted butter, and salt until the mixture looks like damp sand and holds together when pressed.
  3. Press the crumbs firmly into the bottom of the pan using the flat bottom of a measuring cup, then bake for 10 minutes.
  4. Cool the crust for 15 minutes while you make the filling.
Make cheesecake filling
  1. Beat the softened cream cheese and sugar on medium for 3 minutes, scraping the bowl twice, until completely smooth with no lumps.
  2. Beat in the sour cream, then add the eggs one at a time on low speed, mixing just until each disappears.
  3. Stir in the vanilla, flour, and salt until just combined.
Make pumpkin swirl and assemble
  1. Scoop 1½ cups of the cheesecake batter into a separate bowl and whisk in the pumpkin purée, brown sugar, cinnamon, ginger, nutmeg, and cloves until smooth and deeply orange.
  2. Pour the plain cheesecake batter over the cooled crust and smooth the top.
  3. Dollop spoonfuls of the pumpkin batter across the surface, then drag a butter knife through them in long S-shaped passes to marble, stopping after 4 to 5 passes to keep swirls distinct.
Bake and chill
  1. Bake at 325°F for 38–45 minutes, until the edges are set and puffed and the center 3 inches still wobble slightly when you nudge the pan.
  2. Cool completely in the pan for about 2 hours, until room temperature.
  3. Chill at least 4 hours or overnight, until firm for clean cutting.
Cut and serve
  1. Lift the bars out using the parchment overhang and cut into 24 bars with a warm knife, wiping the blade between cuts.

Notes

For the smoothest, crack-resistant swirl, keep everything at room temperature and mix the eggs only until each one disappears—overbeating adds air. Store covered in the refrigerator up to 5 days; freeze the bars (already cut) up to 2 months. For a lighter option, use reduced-fat cream cheese in the same weight.
