You get:

• Texture:
  • Soft, tender crumb
  • Moist without being dense

Chocolate Cake (Two 8- or 9-inch Layers)

• 1¾ cups (220 g) all-purpose flour
• 1¾ cups (350 g) granulated sugar
• ¾ cup (75 g) unsweetened cocoa powder (natural or Dutch-process)
• 2 tsp baking soda
• 1 tsp baking powder
• 1 tsp fine sea salt
• 2 large eggs, room temperature
• 1 cup (240 ml) buttermilk, room temperature
  • or 1 cup milk + 1 tbsp lemon juice/vinegar, rested 5–10 minutes
• ½ cup (120 ml) neutral oil (canola, vegetable, or light olive)
• 2 tsp vanilla extract
• 1 cup (240 ml) hot coffee or boiling water

Chocolate Buttercream Frosting

• 1½ cups (340 g) unsalted butter, softened
• 3½–4 cups (420–480 g) powdered sugar, sifted
• ¾ cup (75 g) unsweetened cocoa powder
• ½ tsp fine sea salt
• 2 tsp vanilla extract
• 4–6 tbsp (60–90 ml) heavy cream or milk

Optional Decoration

• Chocolate curls or shavings
• Sprinkles
• Fresh berries (raspberries/strawberries)

Instructions: Step-by-Step Preparation

1. Prep Pans & Oven

• Preheat oven to 175°C / 350°F.
• Grease and line two 8- or 9-inch (20–23 cm) round cake pans:
  • Line bottoms with parchment
  • Lightly grease and flour the sides

2. Mix Dry Ingredients

In a large bowl, whisk:

• Flour
• Sugar
• Cocoa powder
• Baking soda
• Baking powder
• Salt

Set aside.

3. Mix Wet Ingredients (Except Coffee/Water)

In another bowl (or large jug), whisk:

• Eggs
• Buttermilk
• Oil
• Vanilla

Whisk until smooth and fully combined.

4. Combine Batter

• Pour the wet mixture into the dry ingredients.
• Mix on low with a hand mixer (or whisk) just until combined.
• Slowly pour in hot coffee or boiling water, mixing on low:
  • The batter will become thin—this is correct and gives a moist cake.

5. Bake

• Divide batter evenly between prepared pans.
• Bake for 28–32 minutes (8-inch) or 24–30 minutes (9-inch), until:
  • Tops spring back lightly to the touch
  • A toothpick comes out with a few moist crumbs
• Cool in pans for 10–15 minutes, then turn out onto wire racks to cool completely.

6. Make the Chocolate Buttercream

1. Beat softened butter on medium-high until pale and creamy (2–3 minutes).
2. Add powdered sugar and cocoa powder, 1 cup at a time, mixing on low until combined.
3. Add salt, vanilla, and 4 tbsp cream/milk.
4. Beat on medium-high for 3–4 minutes until light and fluffy.
5. Adjust:
   • Too thick? Add more cream, 1 tbsp at a time.
   • Too thin? Add more powdered sugar.

7. Assemble & Frost the Cake

1. Level layers:
   • If cakes are domed, trim tops with a serrated knife so they’re flat.
2. Layer:
   • Place one cake layer on a stand/plate.
   • Spread a generous layer of frosting over the top.
   • Place the second layer on top, flat side down.
3. Crumb coat:
   • Spread a thin layer of frosting over the top and sides to trap crumbs.
   • Chill 15–20 minutes.
4. Final coat:
   • Add a thicker, smooth layer of frosting over the chilled cake.
   • Decorate with chocolate curls, sprinkles, or berries, if desired.

Let the cake sit at room temperature for 20–30 minutes before slicing.

How to Store It

• Room temperature:
  • Up to 1 day in a cool room, covered.
• Refrigerator:
  • Up to 4–5 days, covered.
  • Bring to room temp before serving for the best texture.
• Leftovers:
  • Store slices in an airtight container.

Smart Ingredient Swaps

• No buttermilk:
  • Use milk + vinegar/lemon juice as noted above.
• Extra rich flavor:
  • Use espresso instead of coffee/water.
• Sweeter frosting:
  • Increase powdered sugar to taste.
• Darker chocolate cake:
  • Use Dutch-process cocoa for a more intense, deep chocolate flavor.
• Dairy-free:
  • Use plant-based milk and vegan butter; frosting texture may vary slightly.

How to Serve It

• Classic:
  • Room-temp slices with a glass of cold milk or coffee.
• Celebration-ready:
  • Decorate with sprinkles, candles, and chocolate shavings.
• Dessert plate:
  • Serve with a scoop of vanilla ice cream or a dollop of whipped cream and berries.

Why is my cake dry?

• Overbaked (check a few minutes early)
• Too much flour (weigh or spoon-and-level)
• Oven too hot (use an oven thermometer if possible)

Do I have to use coffee?
No. Use boiling water instead; coffee just enhances chocolate flavor.
