- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 3/4 cup granulated sugar
- 1/2 cup brown sugar
- 2 large eggs, room temperature
- 1/2 cup vegetable oil
- 1/2 cup whole milk
- 1/4 cup hot brewed coffee
- 2 teaspoons vanilla extract
Chocolate Filling
- 1/2 cup Nutella or chocolate hazelnut spread
- 1/4 cup cream cheese, softened
- 2 tablespoons powdered sugar
Chocolate Ganache
- 1 cup semi-sweet chocolate, finely chopped
- 1/2 cup heavy cream
- 1 tablespoon unsalted butter
Decoration
- 2-4 KitKat bars
- Chocolate curls or shavings (optional)
Equipment
- Mixing bowls
- Whisk
- Measuring cups and spoons
- Rubber spatula
- Small bowl
- Saucepan
- Wire cooling rack
- 8×4-inch loaf pan
- Parchment paper
Optional Substitutions
- For a dairy-free version, replace milk with almond or oat milk and use dairy-free chocolate in the ganache.
- Swap Nutella for peanut butter or dairy-free chocolate spread if preferred.
- Gluten-free flour can be used as a 1:1 substitute for all-purpose flour.
Step-by-Step Instructions
Preheat the oven to 350°F (175°C). Grease an 8×4-inch loaf pan and line it with parchment paper for easy removal.
In a mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
In another bowl, whisk granulated sugar, brown sugar, eggs, vegetable oil, milk, vanilla extract, and hot coffee until smooth.
Gently fold the wet ingredients into the dry ingredients until just combined. Avoid overmixing to keep the cake light and fluffy.
In a small bowl, mix Nutella, softened cream cheese, and powdered sugar until smooth.
Pour half of the cake batter into the prepared loaf pan. Spoon the Nutella filling down the center, keeping it slightly away from the edges to prevent over-spreading.
Cover with the remaining batter, spreading it evenly. Bake for 45 to 55 minutes or until a toothpick inserted near the edge comes out clean.
Let the cake cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
For the ganache, heat the heavy cream until it simmers, then pour it over the chopped chocolate. Let it sit for 2 minutes before stirring in the butter until smooth and glossy.
Pour the ganache over the cooled loaf cake, allowing it to drip naturally down the sides.
Decorate with KitKat bars and optional chocolate curls while the ganache is still soft. Refrigerate for 20 minutes to set before slicing.
