Ingredients

• 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
• 1/2 cup (113g) pumpkin purée
• 2 teaspoons King Arthur Pumpkin Pie Spice*
• 1/2 cup (113g) sour cream
• 3 tablespoons (43g) hot water
• 3 tablespoons (37g) granulated sugar
• 1/8 teaspoon King Arthur Pure Vanilla Plus
• 1/2 cup (57g) sifted confectioners’ sugar
• 2 1/2 teaspoons (12g) water
• 1/4 teaspoon King Arthur Pure Vanilla Plus

Instructions

1. Step 1: Preheat the oven to 350°F with a rack in the middle position. Lightly grease one 8 1/2″ x 4 1/2″ loaf pan or a loaf pan with at least a 6-cup capacity. Place the pan on a baking sheet for added stability, especially if using a specialty loaf pan.
2. Step 2: To make the cake batter: In a large bowl or the bowl of a stand mixer fitted with a flat beater, beat the eggs and sugar until smooth. Gradually add the vegetable oil while beating continuously. Stir in the vanilla, baking powder, and salt.
3. Step 3: Gently mix in the flour, scraping the bowl as needed to fully incorporate it, until a stiff batter forms and no dry ingredients remain.
4. Step 4: Transfer half of the batter (about 1 cup or 350g) into a medium bowl. Stir in the pumpkin purée and pumpkin pie spice just until combined. Set aside.
5. Step 5: To the remaining batter, add the sour cream and beat just until incorporated, less than 1 minute.
6. Step 6: Alternating between the two batters, dollop roughly 2-tablespoon portions into the prepared loaf pan to create a checkerboard effect. Precise measurements aren’t necessary; the charm of this cake is in its free-form swirls.
7. Step 7: Insert an offset spatula or wooden skewer deep into the batter and drag it through in one figure-8 motion. Use just one figure 8 to create a beautiful swirl without over-mixing.
8. Step 8: Bake for 45 to 55 minutes, or until a paring knife inserted in the center comes out clean or with a few moist crumbs attached.
9. Step 9: Cool the cake in its pan for about 5 minutes before turning it out onto a wire rack to cool completely. While cooling, prepare either the soak or the glaze as described next.
10. Step 10: For the soak: In a small bowl, whisk together hot water and sugar until the sugar dissolves. Stir in vanilla, then brush the soak onto the cake. For the glaze (optional): whisk confectioners’ sugar, water, and vanilla until smooth and thin. Slowly pour the glaze over the cooled cake, allowing some drips down the sides.

Tips & Variations

• Use fresh pumpkin purée for the best flavor, or homemade if possible.
• Swap sour cream with Greek yogurt for a tangier taste and slightly lighter texture.
• Try adding chopped nuts or chocolate chips into the batter for extra texture.
• Adding one figure-8 swirl keeps the cake marbled without over-mixing, preserving the distinct pumpkin and plain batters.
• Choose soak for a moist cake or glaze for a sweeter, decorative finish.

Storage

Store leftover pumpkin swirl cake in an airtight container at room temperature for up to 4 days. For longer storage, freeze wrapped tightly. Reheat slices gently in the microwave or enjoy at room temperature for best flavor and texture.

FAQs

Ingredients

Scale 1x2x3x

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

Glaze

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

Instructions

1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and position the rack in the middle. Lightly grease an 8 1/2″ x 4 1/2″ loaf pan or a similarly sized pan with at least a 6-cup capacity. To ensure stability while baking, place the loaf pan on a baking sheet.
2. Make the cake batter: In a large mixing bowl or the bowl of a stand mixer fitted with the flat beater attachment, beat the eggs with granulated sugar until smooth and well combined. Gradually drizzle in the vegetable oil while continuing to beat. Stir in vanilla extract, baking powder, and salt thoroughly.
3. Add flour: Gently fold in the cake flour, scraping the bowl as necessary to combine, until you achieve a stiff batter with no dry flour remaining.
4. Prepare pumpkin batter: Transfer about half of the batter (approximately 1 cup or 350g) into a medium bowl. Fold in the pumpkin purée and pumpkin pie spice just until incorporated. Set aside.
5. Prepare sour cream batter: Add the sour cream to the remaining batter and beat briefly, less than one minute, until just combined.
6. Assemble the batters in the pan: Alternate dolloping roughly 2-tablespoon portions of the pumpkin and sour cream batters into the prepared loaf pan to create a checkerboard pattern. The mixing does not have to be exact; the rustic marbled effect is part of the cake’s charm.
7. Swirl the batters: Using an offset spatula or a wooden skewer, insert it deep into the batter and drag it through the pan in one smooth figure-8 motion to create a beautiful swirl pattern. Avoid over-mixing.
8. Bake: Place the pan in the oven and bake the cake for 45 to 55 minutes, or until a paring knife inserted into the center comes out clean or with only a few moist crumbs clinging.
9. Cool the cake: Let the cake cool in the pan for about 5 minutes. Then remove it from the pan and transfer to a wire rack to cool completely.
10. Make and apply soak or glaze: For the soak: whisk hot water and granulated sugar in a small bowl until sugar dissolves, then stir in vanilla. Brush this soak over the cake surface. Alternatively, for the glaze: whisk together sifted confectioners’ sugar, water, and vanilla until thin and pourable, then slowly pour over the cooled cake, allowing some drips down the sides.
11. Storage: Store leftover cake in an airtight container at room temperature for up to 4 days. For longer storage, freeze securely.

Notes

• The swirl effect is achieved by carefully dragging a skewer in a figure-8 pattern rather than mixing the batters thoroughly.
• Use a loaf pan of at least 6 cups volume to ensure even baking and proper rise.
• You can choose between brushing the cake with a sugar soak for moisture or a sweeter glaze for more pronounced sweetness and decoration.
• Letting the cake cool completely before glazing is important for the glaze to set properly.
• This cake freezes well; wrap it tightly before freezing to maintain freshness.
