Pumpkin Swirl Brownies

Pumpkin Swirl Brownies are a rich and gooey fall dessert combining fudgy chocolate brownie layers with a creamy, spiced pumpkin swirl. Featuring warm pumpkin spice flavors blended perfectly with decadent chocolate, these brownies are moist, tender, and visually stunning with their marbled pumpkin design. Ideal for cozy autumn afternoons, holiday gatherings, or as a comforting treat, they offer an irresistible blend of indulgence and seasonal charm.

  • Total Time: 45-50 minutes
  • Yield: 16 brownies 1x

Ingredients

Scale

Chocolate Brownie Batter

  • 1/2 cup (115g) unsalted butter, melted
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1 cup (200g) brown sugar
  • 2 large eggs (room temperature)
  • 1 teaspoon vanilla extract
  • 3/4 cup (95g) all-purpose flour (or gluten-free flour blend for GF)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt

Pumpkin Swirl Mixture

  • 3/4 cup (180g) pure pumpkin puree (canned or fresh)
  • 1/4 cup (50g) granulated sugar
  • 1 teaspoon ground cinnamon
  • 1 teaspoon pumpkin spice blend
  • 1 tablespoon all-purpose flour (or gluten-free flour blend for GF)

Optional Add-ins and Variations

  • 1/2 cup semi-sweet or white chocolate chips
  • 1/2 cup chopped pecans or walnuts
  • Additional spices: ground ginger, nutmeg to taste
  • For vegan option: substitute eggs with flax eggs and butter with coconut oil

Instructions

  1. Prepare the brownie batter: Melt the butter, then stir in the cocoa powder, brown sugar, and vanilla extract until smooth and glossy. Whisk in the eggs one at a time to combine fully. Next, fold in the dry ingredients—flour, baking powder, and salt—just until incorporated to create a rich, fudgy brownie base.
  2. Make the pumpkin swirl mixture: In a separate bowl, mix together the pumpkin puree, granulated sugar, cinnamon, pumpkin spice blend, and flour until smooth and well combined. This will form the creamy, spiced pumpkin component that contrasts with the chocolate batter.
  3. Layer and swirl: Pour half of the chocolate brownie batter into a prepared baking pan. Dollop half of the pumpkin mixture on top. Repeat with the remaining batters. Use a knife or skewer to gently swirl the two mixtures together to create a beautiful marbled effect without blending completely.
  4. Bake to perfection: Bake the brownies in a preheated oven at 350°F (175°C) for 30 to 35 minutes, or until the edges are set but the center remains slightly gooey. Begin checking doneness around 25 minutes to avoid overbaking. Let the brownies cool slightly before slicing to preserve the swirl design.

Notes

  • Use room temperature eggs to help the batter mix more evenly and develop a smoother texture.
  • Do not overmix the batter to keep brownies tender and moist.
  • Swirl gently with a knife to maintain distinct marbled layers without blending the batters too much.
  • Test for doneness starting at 25 minutes to avoid drying out the brownies.
  • Allow brownies to cool completely or chill briefly before cutting for neat slices and to maintain the swirl pattern.
