Chai Cinnamon Swirl Bundt Cake

Ingredients:

  • 3 cups (375g) all-purpose flour (spoon & leveled)
  • 2 and 1/2 teaspoons baking powder
  • 1 and 1/2 teaspoons salt
  • 1 and 1/2 cups (3 sticks; 345g) unsalted butter, softened to room temperature
  • 1 cup (200g) packed light or dark brown sugar
  • 1/2 cup (100g) granulated sugar
  • 5 large eggs, at room temperature
  • 1/2 cup (120g) full fat sour cream, at room temperature
  • 2 teaspoons pure vanilla extract
  • 3/4 cup (180ml) milk, at room temperature
  • optional for topping: brown butter icing, salted caramel, or maple icing

Chai Cinnamon Swirl

  • 3/4 cup (150g) packed light or brown sugar
  • 2 teaspoons ground cinnamon
  • 1 teaspoon ground ginger
  • 1 teaspoon ground cardamom
  • 1/2 teaspoon ground allspice

Directions:

  1. Preheat the oven to 350°F (177°C) and grease a 10-inch bundt pan.
  2. For the cake: Whisk the flour, baking powder, and salt together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a paddle or whisk attachment beat the butter, brown sugar, and granulated sugar together until creamed, about 2 minutes. Add the eggs, sour cream, and vanilla and beat on medium speed until combined. Scrape down the sides and bottom of the bowl as needed. The mixture will look curdled; that's ok-- it will come together when you add the dry ingredients.
  3. Pour the dry ingredients into the wet ingredients, add the milk, and beat on medium speed it all until the batter is completely combined. Batter is thick, yet silky.
  4. For the chai cinnamon swirl: Mix the swirl ingredients together in a medium bowl.
  5. Pour half of the cake batter evenly into the prepared bundt pan. Sprinkle the swirl ingredients evenly on top-- it will be a thick layer of swirl! Cover evenly with remaining cake batter.
  6. Bake for 55-70 minutes or until a toothpick inserted into the cake comes out clean with just a couple lightly moist crumbs. This is a large, heavy cake so don't be alarmed if it takes a little longer in your oven.
  7. Once done, remove from the oven and allow to cool for 2 hours inside the pan. Then, invert the slightly cooled bundt cake onto a wire rack or serving dish. Allow to cool completely.
  8. As the cake cools, prepare the icing. Try my brown butter icing, salted caramel, or maple icing. I used the brown butter icing in these photos. Drizzle icing over cake before slicing and serving.
  9. Cover leftover cake tightly and store at room temperature for a couple days and/or in the refrigerator for up to 5 days.

Make ahead tip: You can make the entire cake ahead of time (before topping with icing). Cover cooled cake and refrigerate for up to 2 days. Bring to room temperature before icing and serving. Baked cake can be frozen up to 3 months. Allow to thaw overnight in the refrigerator and bring to room temperature (if desired) before icing and serving.

Recipe Notes:

Why is everything at room temperature? All refrigerated items should be at room temperature so the batter mixes together easily and evenly. Read here for more information.
