1 and 3/4 cups (220g) all-purpose flour
3/4 cup (65g) unsweetened natural cocoa powder
1 and 3/4 cups (350g) granulated sugar
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon salt
optional: 2 teaspoons espresso powder
1/2 cup (120ml) canola or vegetable oil
2 large eggs, at room temperature
3/4 cup (180g) full fat sour cream, at room temperature1
1/2 cup (120ml) buttermilk, at room temperature1
2 teaspoons pure vanilla extract
1/2 cup (120ml) boiling hot water2
Cream Cheese Filling
12 ounces (336g) full-fat block cream cheese, softened to room temperature
1 large egg
1/4 cup (50g) granulated sugar
1/2 teaspoon pure vanilla extract
Salted caramel sauce or chocolate ganache
Preheat the oven to 350°F (177°C) and grease a 10-inch bundt pan.
Whisk the flour, cocoa powder, sugar, baking soda, baking powder, salt, and espresso powder (if using) together in a large bowl. Set aside. Using a handheld or stand mixer fitted with a whisk attachment (or you can use a whisk) mix the oil, eggs, sour cream, buttermilk, and vanilla together until combined. Pour the wet ingredients into the dry ingredients, add the hot water, and whisk or beat it all until the batter is completely combined. Set aside as you prepare the cream cheese filling.
Make the cream cheese filling: Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the cream cheese on high speed until no lumps remain. Beat in the remaining ingredients on medium-high speed until combined.
Pour half of the chocolate batter evenly into the prepared bundt pan. Spread all of the cream cheese filling evenly on top. The cream cheese batter is thick, so you’ll have to spoon it on top and do your best to spread it around– avoid it touching the sides of the pan. See photo above for a visual. Pour the remaining chocolate batter evenly on top.
Bake for 55-65 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.
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 cake to cool completely, then refrigerate for 2 hours. Garnish with optional toppings, then slice and serve.
Leftovers keep well stored in the refrigerator for a few days.
Make ahead tip: Baked cake can be frozen up to 3 months. Allow to thaw overnight in the refrigerator before serving.
