This delectable cake is as delicious as it is beautiful. It’s straightforward to assemble and makes a perfect family-sized dessert.

Happy Halloween! I couldn’t resist sharing this recipe today, though it’s wonderful any time during pumpkin season. Rich, black cocoa chocolate swirls meet spiced pumpkin-vanilla batter to create a marbled cake that looks stunning and tastes even better.

I’ve been juggling several photography and recipe projects lately—cookbook work for a documentary, shoots for VegNews, a holiday spread focused on vegan caramel, plus freelance jobs—so I’m excited to have a bit more time during the holidays to share recipes here. Cooking remains my favorite way to be creative.

If you follow me on social media, you may have seen some of the video content I’ve been posting. I appreciate feedback on the new site design—if anything feels difficult to use or read, let me know. Now onto helpful substitutions and tips for this recipe.

Substitutions & Tips

• All-purpose flour – You can likely use a 1:1 gluten-free flour blend; expect a slightly denser texture than with regular AP flour.
• Sugar – Evaporated cane sugar works well for this cake. Replacing some of it in the pumpkin batter with light brown sugar will add warmth and moisture.
• Black cocoa vs. Dutch-processed cocoa – Black cocoa gives a very dark color and intense chocolate flavor, so the recipe calls for a smaller amount. If you only have Dutch-processed cocoa, use 1/3 cup instead of 1/4 cup.
• Olive oil – To reduce oil, substitute an equal amount of pumpkin puree in the batter.
• Apple cider vinegar – White vinegar is an acceptable swap; both activate baking soda effectively.
• Vegetable shortening – Shortening keeps vegan frostings stable at room temperature. Use fresh shortening to avoid graininess in the frosting.
• Vegan butter – I used salted vegan butter in a half-shortening, half-butter frosting. Choose the vegan butter you prefer; chilling briefly can help if it becomes too soft.
• Powdered sugar – Sift powdered sugar before using it in frosting to avoid lumps. As an alternative, blend granulated sugar until very fine.
• Coloring – I used a combination of spices and gel food coloring for the orange frosting. Use what you prefer; gel colors work well and require only a small amount.
• Frosting handling – If your frosting becomes too soft while assembling, chill it 5–10 minutes so it firms up for smoothing and piping.

This cake was partly inspired by a layered cake on a recent seasonal magazine cover. If the full marbled layer cake feels like too much, consider a simpler pumpkin cake with cream cheese frosting as an easier alternative.

Ingredients

Chocolate Batter

• 1 1/2 cups (212 g) unbleached all-purpose flour
• 1 cup (230 g) sugar
• 1/4 cup (25 g) black cocoa powder
• 1 teaspoon baking soda
• 1/4 teaspoon sea salt
• 1 cup (245 ml) cold water
• 2 tablespoons (30 ml) olive oil
• 2 tablespoons (30 g) pumpkin puree
• 1 tablespoon (15 ml) apple cider vinegar
• 1 teaspoon vanilla extract

Pumpkin Spice Batter

• 1 3/4 cups (242 g) unbleached all-purpose flour
• 1 cup (230 g) sugar
• 1 teaspoon baking soda
• 1 teaspoon pumpkin pie spice
• 1/2 teaspoon ground turmeric, optional (for color)
• 1/4 teaspoon sea salt
• 1 cup (245 ml) cold water
• 3 tablespoons (45 g) pumpkin puree
• 1 tablespoon (15 ml) olive oil
• 1 tablespoon (15 ml) apple cider vinegar
• 1 teaspoon vanilla extract

Frosting

• 1 cup (227 g) vegan butter
• 1 cup (140 g) vegetable shortening
• 4 cups (450 g) powdered sugar, sifted
• 2 tablespoons (30 ml) non-dairy milk
• 1 teaspoon vanilla extract
• 1 teaspoon orange gel food coloring, optional
• 1/2 teaspoon yellow gel food coloring, optional

Ganache

• 1/2 cup (95 g) vegan chocolate chips
• 1/4 cup (60 ml) non-dairy milk
• Vegan sprinkles, optional

Instructions

1. Preheat oven to 350°F and lightly grease three 6-inch cake pans.
2. For the chocolate batter: sift flour, sugar, black cocoa, baking soda, and salt. Whisk in water, olive oil, pumpkin puree, apple cider vinegar, and vanilla until smooth. Set aside.
3. For the pumpkin batter: sift flour, sugar, baking soda, pumpkin pie spice, turmeric (if using), and salt. Whisk in water, pumpkin puree, olive oil, apple cider vinegar, and vanilla until smooth.
4. Divide the two batters between the three pans, alternating spoonfuls. Use a toothpick or butter knife to swirl gently—avoid over-mixing to keep distinct marbling.
5. Bake on the middle rack for 38–40 minutes, or until a toothpick comes out clean. Cool on a rack for 20 minutes, then chill in the refrigerator.
6. For the frosting: beat shortening and vegan butter until very fluffy. Gradually add sifted powdered sugar, 1/2 cup at a time, mixing on high. Add non-dairy milk and vanilla, beating until smooth and light.
7. Reserve 1 cup (about 150 g) of frosting for piping. Tint the remaining frosting with gel colors as desired.
8. Trim the rounded tops of the chilled layers. Place one layer on a serving plate, spread a 1/2-inch layer of frosting, add the next layer, repeat, then place the final layer cut-side down.
9. Crumb-coat the cake with a thin layer of tinted frosting and refrigerate for 20 minutes. Smooth the sides with a metal scraper if needed.
10. Make the ganache: heat chocolate chips with non-dairy milk in 30–45 second bursts in the microwave or use a double boiler. Stir until smooth and let cool 2–3 minutes.
11. Pour the ganache over the top, letting drips fall down the sides. Add sprinkles if you like. Chill 15 minutes, then pipe a border with the reserved white frosting. Chill until ready to serve.
12. Allow the cake to warm toward room temperature before serving so the frosting is easy to cut and enjoy.
