The Ultimate Fudgy Pumpkin Brownie Swirl Pie

A perfect slice of homemade Pumpkin-Brownie Swirl Pie being served with a scoop of melting vanilla ice cream.

A decadent hybrid dessert, this Pumpkin-Brownie Swirl Pie features a fudgy brownie layer and a creamy pumpkin pie filling baked together in a deep-dish pie plate. The recipe starts by creating a rich brownie batter, a portion of which is par-baked to form a bottom crust. A smooth, spiced pumpkin pie custard is then poured over the brownie base. The remaining brownie batter is thinned slightly and spooned on top, then swirled into the pumpkin filling to create a beautiful marbled pattern before the final bake.

Ingredients

Scale
  • For the Brownie Batter:
  • 1 stick (8 tablespoons) unsalted butter, plus more for the pie plate
  • 1 (12-ounce) bag semisweet chocolate chips
  • 2/3 cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon pure vanilla extract
  • 1/2 cup all-purpose flour
  • 2 tablespoons unsweetened cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • For the Pumpkin Filling:
  • 1 cup pure pumpkin puree
  • 1 cup heavy cream
  • 1 large egg
  • 1/4 cup granulated sugar
  • 1/4 cup all-purpose flour
  • 1/2 teaspoon pumpkin pie spice
  • For Serving (optional):
  • Vanilla ice cream

Instructions

  1. Preheat the oven to 350°F. Butter the bottom and side of a 9 1/2-inch deep-dish pie plate.
  2. Make the Brownie Batter: In a medium saucepan over medium heat, melt the butter, chocolate chips, and brown sugar, whisking occasionally, until smooth. Remove from the heat.
  3. Whisk in the eggs one at a time, then whisk in the vanilla until smooth.
  4. Whisk in the flour, cocoa powder, baking powder, and salt until just combined.
  5. Par-Bake the Crust: Pour about one-third of the brownie batter into the prepared pie plate and spread it to cover the bottom. Reserve the remaining batter. Bake for about 20 minutes, until just starting to set.
  6. Make the Pumpkin Filling: While the brownie crust bakes, combine the pumpkin puree, heavy cream, egg, granulated sugar, flour, and pumpkin pie spice in a medium bowl. Whisk until smooth.
  7. Assemble and Bake: Pour the pumpkin filling over the warm, par-baked brownie layer.
  8. Stir 1 tablespoon of water into the remaining brownie batter to thin it slightly. Spoon the batter in about 6 scoops onto the pumpkin filling.
  9. Use the back of a spoon to gently pull the brownie batter into the pumpkin filling to create a swirled pattern.
  10. Bake for 40 to 45 minutes, until the pie is set.
  11. Transfer the pie to a wire rack and let it cool completely before serving. Serve with vanilla ice cream, if desired.

Notes

  • This pie has a unique construction where the brownie batter serves as both the bottom crust and the decorative swirl on top.
  • Par-baking the bottom brownie layer is a key step to ensure it is fully cooked.
  • It is important to let the pie cool completely to allow the pumpkin custard to set properly before slicing.
