Ingredients

Scale

Cake Batter

  • 2 large eggs, at room temperature
  • 1 cup (198g) granulated sugar
  • 3/4 cup (149g) vegetable oil
  • 1 tablespoon (17g) King Arthur Pure Vanilla Plus
  • 2 teaspoons baking powder
  • 3/4 teaspoon table salt
  • 2 cups (240g) King Arthur Unbleached Cake Flour

Pumpkin Batter

  • 1/2 cup (113g) pumpkin purée
  • 2 teaspoons King Arthur Pumpkin Pie Spice

Sour Cream Batter

  • 1/2 cup (113g) sour cream

Soak

  • 3 tablespoons (43g) hot water
  • 3 tablespoons (37g) granulated sugar
  • 1/8 teaspoon King Arthur Pure Vanilla Plus

Glaze (optional)

  • 1/2 cup (57g) confectioners’ sugar, sifted
  • 2 1/2 teaspoons (12g) water
  • 1/4 teaspoon King Arthur Pure Vanilla Plus

Instructions

  1. Preheat Oven and Prepare Pan: Preheat the oven to 350°F and place a rack in the middle position. Lightly grease an 8 1/2″ x 4 1/2″ loaf pan or another pan with at least 6-cup capacity. Place the pan on a baking sheet for added stability.
  2. Make Cake Batter: In a large bowl or stand mixer with a flat beater, beat the eggs and granulated sugar until smooth and well combined. Gradually add the vegetable oil, continuing to beat. Stir in vanilla extract, baking powder, and salt.
  3. Add Flour: Gently mix in the cake flour, scraping the bowl as needed, until a stiff batter forms with no dry flour remaining.
  4. Prepare Pumpkin Batter: Transfer half of the batter (about 1 cup or 350g) to a medium bowl. Mix in pumpkin purée and pumpkin pie spice until just combined. Set aside.
  5. Add Sour Cream: To the remaining batter, beat in the sour cream until fully incorporated, about less than a minute.
  6. Layer Batters in Pan: Alternating between pumpkin and sour cream batters, dollop 2-tablespoon portions into the prepared loaf pan in a checkerboard pattern. Precise measurements aren’t critical; a free-form approach creates the best swirl effect.
  7. Create Swirl: Insert an offset spatula or wooden skewer deep into the batter and drag it through in one figure-8 motion to create a swirl. Avoid over-mixing to keep distinct patterns.
  8. Bake: Bake the cake for 45 to 55 minutes, or until a paring knife inserted into the center comes out clean or with a few moist crumbs attached.
  9. Cool Cake: Let the cake cool in the pan for about 5 minutes before removing it onto a wire rack to cool completely.
  10. Prepare Soak or Glaze: For the soak, whisk hot water and granulated sugar in a small bowl until dissolved, then add vanilla extract and brush onto the warm cake. Alternatively, prepare the glaze by whisking together sifted confectioners’ sugar, water, and vanilla to form a thin glaze and slowly pour it over the cooled cake allowing drips over the sides.
  11. Store: Store leftover cake in an airtight container at room temperature for up to 4 days or freeze for longer storage.

Notes

  • Use room temperature eggs for better mixing and texture.
  • Be careful not to over-swirl the batters to preserve the marbled effect.
  • Choose between soaking the warm cake with a sugar vanilla soak or glazing the cooled cake according to your preference.
  • Loaf pans smaller than 6 cups capacity may cause overflow; use a baking sheet under the pan for stability.
  • Freezing the cake is a great option to extend shelf life; thaw at room temperature before serving.
