Ingredients
Chocolate Cake Batter:
- 2 cups + 2 tbsp cake flour
- 1 ½ cups granulated sugar
- ½ cup packed dark brown sugar
- 1 ½ tsp baking powder
- ¾ tsp baking soda
- 1 tsp fine sea salt
- 6 ½ tbsp unsalted butter, cubed and at room temp
- 1 cup sour cream, room temp
- ½ cup whole milk, room temp
- 2 large eggs, room temp
- ¼ cup vegetable oil
- 1 ½ tsp vanilla extract
- 1 cup hot coffee
- ¾ cup unsweetened dark cocoa powder
- 1 batch chocolate fudge frosting
Chocolate Cake Soak:
- 5 tbsp water
- ⅛ cup unsweetened cocoa powder
- 2 ½ tbsp granulated sugar
- 1 tsp vanilla extract

Step-by-Step Instructions
- Preheat & Prep Pans:
Preheat oven to 350°F (180°C). Line two 8-inch cake pans with parchment paper. - Mix Dry Ingredients:
In a stand mixer, combine cake flour, sugars, baking powder, baking soda, salt, and butter. Mix on low until it resembles coarse sand (~3 mins). - Combine Wet Ingredients:
In a bowl, whisk sour cream, milk, eggs, oil, and vanilla. Separately, mix hot coffee and cocoa powder until smooth. - Make Batter:
Stream wet mixture into the dry ingredients, followed by the coffee-cocoa mix. Mix until just combined. Scrape bowl as needed. 🌀 - Bake the Cakes:
Divide batter evenly (~740g each pan). Bake for 30–35 mins or until a toothpick comes out with moist crumbs. - Cool & Release:
Cool in pans for 20 mins, run a spatula around edges, then flip out onto a rack to cool completely. - Make Cake Soak:
In a pot, combine water, cocoa, sugar, and vanilla. Simmer until slightly thickened. Cool completely. - Trim & Soak Cakes:
Trim a thin layer from the cake tops. Brush each layer with the chocolate soak for extra moistness. 🍫 - Assemble & Frost:
Use your favorite chocolate fudge frosting to stack and cover the cake. Garnish with chocolate shavings for a bakery-worthy finish!

Pro Tips
- Make Ahead: Bake cakes a day early and store tightly wrapped to save time!
- Sour Cream Swap: Greek yogurt works well if you’re out of sour cream.
- Storage: Store leftovers in an airtight container at room temp for 2–3 days or refrigerate for longer freshness.
