Pumpkin spice cake layers paired with a fragrant vanilla chai buttercream — inspired by Starbucks’ vanilla chai with pumpkin cold foam. This cake balances warm fall spices with a smooth, creamy frosting for a dessert that’s perfect for holiday gatherings.
With Thanksgiving approaching, it’s time to decide what dessert you’ll bring or serve. Whether you’re hosting the whole meal or contributing a dish to share, choose something everyone will love. This Pumpkin Vanilla Chai Cake delivers classic pumpkin flavor with a chai-spiced buttercream that guests will request year after year.
Pumpkin Cake layers
The pumpkin cake layers come from the same batter used in other popular variations like Oreo and Biscoff pumpkin cakes. They offer a tender, slightly crumbly crumb and a well-rounded pumpkin flavor, thanks to the balance of sugars, pumpkin purée, and warm spices.
Chai Buttercream
This buttercream is packed with flavor. Chai is a black tea blended with warming spices like cinnamon, cardamom, ginger, and cloves. For this recipe, a chai tea extract concentrates those flavors into the frosting without adding liquid. If you prefer, you can use a homemade chai spice blend powder (a suggested blend is provided in the recipe notes).
How to bake the most perfect pumpkin cake layers
Start by beating the eggs and sugars until light and airy. This step adds structure and helps the cake rise evenly. Add the dry ingredients to the wet mixture on low speed and avoid overmixing once the flour has been incorporated. Overmixing can develop gluten and lead to dense, domed, or dry cakes.
Bake “low and slow”: set the oven to 325°F (about 163°C). A lower temperature encourages a steady rise and reduces the risk of browned edges while the center is still baking. Allow the batter to set and bake through gently for a moist, even crumb.
How to store leftover cake
After serving, let any leftover cake cool completely and chill in the refrigerator for a few hours. Once cooled, wrap the cake layers tightly in plastic wrap (or double-wrap for extra protection) and freeze for up to six months. Properly stored slices or layers will keep their texture and flavor.
If you’d like more fall cake ideas, try variations like Pumpkin Oreo, Pumpkin Biscoff, or Maple Pecan cakes — each brings a different twist on classic autumn flavors.
Recipe
Pumpkin Vanilla Chai Cake
Ingredients
For the Pumpkin Cake
- 1 ½ cups granulated sugar
- ¾ cup light brown sugar, packed
- 5 large eggs, room temperature
- 1 cup vegetable oil
- 2 teaspoons vanilla
- 2 cups pumpkin purée (not pie filling)
- 3 cups all-purpose flour
- 2 Tablespoons baking powder
- ¼ teaspoon cardamom
- 3 teaspoons ground cinnamon
- 1 ½ teaspoons ground ginger
- 1 teaspoon nutmeg
- 1 teaspoon salt
For the Vanilla Chai Buttercream
- 2 cups unsalted butter, chilled
- 7 cups powdered sugar
- 2 teaspoons pure vanilla extract
- 2 Tablespoons heavy whipping cream, room temperature
- ¼ teaspoon salt
- 1 teaspoon chai tea extract (or see notes for a spice blend)
Instructions
- Preheat oven to 325°F. Spray four 6-inch pans or three 8-inch pans with cooking spray, line with parchment, and spray again. Set aside.
- In a medium bowl, whisk together flour, baking powder, cardamom, cinnamon, ginger, nutmeg, and salt. Set aside.
- In a stand mixer fitted with the paddle attachment, cream the granulated sugar and eggs on medium speed until light and fluffy.
- Add the oil and vanilla and beat on medium for about 30 seconds until incorporated. Add the pumpkin purée and mix until combined, about 30 seconds.
- With the mixer on the lowest speed, gradually add the dry ingredients to the pumpkin and egg mixture until just combined. Do not overmix.
- Divide the batter evenly among the prepared pans. Smooth the tops with the back of a spoon.
- Bake until a toothpick inserted in the center comes out clean or with a few moist crumbs. Mine took about 32 minutes; baking time may range from 30–35 minutes depending on your oven.
- Allow cakes to cool in the pans for 20 minutes, then transfer to a wire rack to finish cooling to room temperature.
- Once cooled, wrap layers in plastic and refrigerate or freeze. They will keep up to 5 days in the fridge or up to 6 months in the freezer when wrapped tightly.
- For the Vanilla Chai Buttercream: In a stand mixer fitted with the paddle attachment, beat the chilled butter on medium-high for about 6 minutes until creamy and light in color.
- Add the powdered sugar on the lowest speed, mixing just until incorporated. Add vanilla, cream, salt, and chai extract. Increase speed and beat on high for 3 minutes, scrape the bowl, and beat again until smooth.
- Use a rubber spatula or wooden spoon to press out any remaining air pockets for a silky buttercream texture.
- Assembly: Level the cake layers if needed. Place a small dollop of frosting on the cake board to anchor the cake. Place the first layer top-side up and spread about 1 cup of chai buttercream evenly. Place the next layer top-side down, add another cup of frosting, and repeat for remaining layers.
- Apply a thin crumb coat of buttercream around the cake and freeze for 10–15 minutes to set. Finish frosting the cake with the remaining buttercream and bring to room temperature before serving.
Notes
If you don’t have chai tea extract, make a substitute spice mix:
- 2 ½ teaspoons ground cinnamon
- 1 ¼ teaspoons ground ginger
- 1 ¼ teaspoons ground cardamom
- ½ teaspoon ground allspice
- ½ teaspoon black pepper
Blend these spices to taste and use approximately 1 teaspoon of the mixture in place of the chai extract for the buttercream.
