Ingredients

1 cup (120g) all-purpose flour
1/2 cup (50g) unsweetened cocoa powder (preferably Dutch-processed)
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
1/2 cup (100g) granulated sugar
1/2 cup (100g) packed brown sugar
2 large eggs
1/2 cup (120ml) vegetable oil
1 teaspoon vanilla extract
3/4 cup (180ml) buttermilk
1/2 cup (120ml) boiling water

Instructions

Preheat your oven to 350°F (175°C). Grease a standard loaf pan (8×4 inches) and line it with parchment paper for easy removal.
In a large mixing bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt until evenly combined.

In a separate bowl, beat the eggs with both sugars until the mixture is light and fluffy, about 2-3 minutes.
Add the vegetable oil and vanilla extract to the egg mixture, mixing well until combined.
Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix just until smooth.

Carefully pour in the boiling water and stir gently until the batter is uniform. The batter will be thin, which is normal.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Check around the 50-minute mark to prevent overbaking.

Remove from oven and let the cake cool in the pan for about 15 minutes. Then, transfer it to a wire rack to cool completely before slicing.

Tips

Use Dutch-processed cocoa for a richer flavor and darker color. Natural cocoa can be substituted but may alter the acidity slightly.
If you don’t have buttermilk, make a substitute by adding 1 teaspoon of vinegar or lemon juice to 3/4 cup of milk and letting it sit for 5 minutes.

Do not overmix the batter once the dry ingredients are added, as this can make the cake dense.
For a more intense chocolate flavor, add a handful of chocolate chips into the batter before baking.
Ensure your oven temperature is accurate with an oven thermometer for best results.

Serving Suggestions

Serve slices of the loaf cake plain, dusted with powdered sugar, or topped with a dollop of whipped cream. It pairs beautifully with a scoop of vanilla ice cream or a drizzle of chocolate ganache for extra indulgence. For a lighter option, serve with fresh berries on the side.

Variations

For a different twist, consider adding chopped nuts such as walnuts or pecans into the batter. You can also swirl in a layer of cream cheese or chocolate spread before baking for a marbled effect. To make it more decadent, top with a chocolate glaze or ganache once cooled.

Storage and Reheating

Store leftover cake in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. To keep it moist, cover the loaf with plastic wrap or foil. Reheat slices in the microwave for about 10-15 seconds if you prefer warm cake, or enjoy straight from the fridge for a firmer texture.

Frequently Asked Questions

Can I make this cake gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend designed for baking. Be sure to check that the cocoa powder and other ingredients are gluten-free as well.

Why is my cake dense or flat?

This can happen if the batter is overmixed, the oven temperature is too low, or if the baking soda and powder are expired. Make sure to mix gently after adding dry ingredients and verify your oven’s temperature for optimal baking conditions.

Can I use cocoa powder with a different fat content?

Yes, but the flavor and color may vary slightly. Dutch-processed cocoa tends to produce a richer, darker cake. Adjust the recipe if using natural cocoa, as it is more acidic and may require additional leavening adjustments.

Is this cake suitable for freezing?

Absolutely. Wrap the cooled loaf tightly in plastic wrap and then foil. Freeze for up to 3 months. Thaw at room temperature or in the refrigerator before slicing and serving.

What if I don’t have buttermilk?

Replace it with a homemade buttermilk substitute by adding 1 teaspoon of vinegar or lemon juice to 3/4 cup of milk. Let it sit for 5 minutes before adding to the batter. This helps mimic the acidity needed for a tender crumb.

How do I know when the cake is done?

Insert a toothpick into the center; if it comes out clean or with a few moist crumbs, the cake is ready. Because oven temperatures vary, start checking at the 50-minute mark to prevent overbaking.
