Ingredients
Dry Ingredients:
-
2½ cups (312 g) all-purpose flour
-
1 cup (100 g) unsweetened cocoa powder
-
2½ tsp baking soda
-
1 tsp baking powder
-
1 tsp salt
Wet Ingredients:
-
1 cup (227 g) unsalted butter, softened
-
2½ cups (500 g) granulated sugar
-
4 large eggs, room temperature
-
2 tsp vanilla extract
-
1 cup (240 ml) vegetable oil
-
1½ cups (360 ml) buttermilk, room temperature
-
1 cup (240 ml) hot coffee or boiling water
Instructions
1️⃣ Preheat & Prepare Pans
Preheat your oven to 175°C (350°F).
Grease and line three 8-inch round cake pans with parchment paper.
2️⃣ Combine Dry Ingredients
In a large bowl, whisk together:
-
Flour
-
Cocoa powder
-
Baking soda
-
Baking powder
-
Salt
Set aside.
3️⃣ Cream Butter & Sugar
In another large bowl, cream together softened butter and sugar using a hand or stand mixer.
Beat on high until light and fluffy (about 3–5 minutes).
4️⃣ Add Eggs, Vanilla & Oil
Beat in eggs, one at a time, mixing well after each.
Stir in vanilla extract and vegetable oil until smooth and emulsified.
5️⃣ Alternate Dry Ingredients & Buttermilk
Gradually add the dry ingredients in thirds, alternating with the buttermilk, starting and ending with dry.
Mix just until combined — don’t overmix.
6️⃣ Stir in Hot Coffee
Slowly pour in the hot coffee (or boiling water) and mix until the batter is smooth.
The batter will be thin — this is key to a super moist crumb.
7️⃣ Bake
Divide the batter evenly among the prepared pans.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
