| Ingredient | Quantity |
| All-purpose flour | 1Âľ cups (220 g) |
| Unsweetened cocoa powder | ¾ cup (65–70 g) |
| Granulated sugar | 1½ cups (300 g) |
| Baking powder | 1 teaspoon |
| Baking soda | 1 teaspoon |
| Salt | ½ teaspoon |
| Semi-sweet chocolate chips | 1 cup (170 g) |
Wet Ingredients
| Ingredient | Quantity |
| Vegetable oil | ½ cup (120 ml) |
| Large eggs | 3, room temperature |
| Buttermilk | 1 cup (240 ml) |
| Vanilla extract | 1 teaspoon |
| Hot water | ½ cup (120 ml) |
Step-by-Step Instructions
Prepare the Loaf Pans
Preheat your oven to 350°F (175°C).
Lightly grease two 9 Ă— 5-inch loaf pans.
Line each pan with parchment paper, leaving some parchment extending over the long sides.
The overhang will act as handles, making it much easier to lift the finished cakes from the pans.
Prepare the Dry Ingredients
In a large mixing bowl, sift together the:
- All-purpose flour
- Cocoa powder
- Baking powder
- Baking soda
- Salt
Add the granulated sugar and whisk everything together until evenly distributed.
Sifting the cocoa powder is particularly helpful because cocoa can contain small lumps.
Prepare the Wet Ingredients
In a separate bowl, whisk together the vegetable oil, eggs, buttermilk, and vanilla extract.
Continue whisking until the mixture is smooth and evenly combined.
Using room-temperature eggs and buttermilk helps the ingredients incorporate more easily.
Combine the Batter
Make a well in the center of the dry ingredients.
Pour the wet mixture into the center.
Using a spatula or wooden spoon, gently fold the ingredients together.
Stop mixing as soon as there are no large pockets of dry flour remaining.
Do not overmix.
Overmixing can develop too much gluten and result in a heavier loaf.
Add the Hot Water
Slowly pour the ½ cup hot water into the batter while gently stirring.
The batter will become noticeably thinner.
Don’t worry — this is normal.
The hot water helps hydrate and intensify the cocoa flavor while contributing to the moist texture of the finished cake.
Add the Chocolate Chips
Fold the semi-sweet chocolate chips into the batter.
Reserve a small handful if you want to scatter a few chips over the tops before baking.
Fill the Pans
Divide the batter evenly between the two prepared loaf pans.
Try to distribute the batter equally so both cakes finish baking at approximately the same time.
If desired, sprinkle a few additional chocolate chips over the surface.
Bake
Place both loaf pans in the preheated oven.
Bake at 350°F (175°C) for approximately 45–55 minutes.
Begin checking around the 45-minute mark.
Insert a toothpick or cake tester into the center of each loaf.
The cakes are ready when the tester comes out with a few moist crumbs but no wet batter.
Avoid overbaking, as this can make the chocolate loaves drier.
Cool the Cakes
Remove the loaf pans from the oven.
Allow the cakes to cool in the pans for approximately 10 minutes.
Carefully use the parchment-paper overhang to lift each loaf from its pan.
Transfer the cakes to a wire rack.
Allow them to cool completely before slicing.
For the cleanest slices, wait until the cakes are fully cooled.
Best Tips for a Perfect Chocolate Loaf
Use parchment paper. The parchment overhang makes removing the cakes incredibly easy and helps preserve their delicate edges.
Measure flour accurately. Too much flour can make the loaf dense and dry. For the most consistent results, weighing the flour is ideal.
Don’t overmix. Once the flour disappears, stop mixing.
Don’t be concerned about thin batter. The addition of hot water intentionally creates a relatively loose batter.
Use room-temperature eggs. They blend more smoothly with the oil and buttermilk.
Don’t overbake. Chocolate cakes can look moist even when they are perfectly baked, so a few moist crumbs on the toothpick are desirable.
Cool completely before slicing. The crumb continues to set as the loaf cools, and the chocolate chips firm up.
Best Ingredient Options
Cocoa Powder
Unsweetened cocoa powder works well for this recipe.
Dutch-process cocoa can provide a darker color and smoother chocolate flavor, while natural cocoa powder gives a slightly more pronounced cocoa character.
Chocolate Chips
Semi-sweet chocolate chips provide a balanced sweetness.
You can substitute dark chocolate chips, milk chocolate chips, or chopped chocolate depending on your preference.
Buttermilk
Buttermilk adds moisture and a subtle tang that complements the chocolate.
If you don’t have buttermilk, combine 1 cup milk with 1 tablespoon white vinegar or lemon juice.
Let the mixture stand for approximately 5 minutes before using.
Vegetable Oil
A neutral vegetable oil helps create a moist crumb.
Canola oil, sunflower oil, or another neutral-flavored oil can also work well.
🍫 Recipe Variations
Triple Chocolate Loaf
For an even more decadent cake, add ½ cup chocolate chunks in addition to the chocolate chips.
You can also finish the cooled loaves with a simple chocolate glaze.
Chocolate Orange Loaf
Add 1 tablespoon finely grated orange zest to the wet ingredients for a bright citrus-chocolate combination.
Chocolate Espresso Loaf
Add 1–2 teaspoons instant espresso powder to the dry ingredients. The coffee flavor doesn’t need to be dominant; it simply enhances the chocolate character.
Chocolate Nut Loaf
Fold ½ cup chopped walnuts or pecans into the batter along with the chocolate chips.
Chocolate Raspberry Loaf
Add fresh or frozen raspberries carefully to the batter for a fruity contrast.
If using frozen berries, don’t thaw them first.
Plain Chocolate Loaf
Simply leave out the chocolate chips for a smooth, classic chocolate cake with a more uniform crumb.
🍫 Optional Chocolate Glaze
If you prefer a more elegant finish, allow the loaves to cool completely before glazing.
Combine:
| Ingredient | Quantity |
| Powdered sugar | 1 cup |
| Unsweetened cocoa powder | 2 tablespoons |
| Milk | 2–3 tablespoons |
| Vanilla extract | ½ teaspoon |
Whisk everything together until smooth.
Drizzle over the completely cooled loaf and allow the glaze to set for approximately 15–20 minutes before slicing.
What to Serve With
Serve slices of chocolate loaf with a cup of coffee, espresso, tea, or cold milk.
For dessert, add a scoop of vanilla ice cream and a drizzle of chocolate sauce.
Fresh strawberries, raspberries, or whipped cream also make beautiful accompaniments.
For a simple presentation, dust the cooled loaf lightly with powdered sugar.
Make-Ahead Instructions
These chocolate loaves are excellent for making ahead.
Bake them up to one day before serving and allow them to cool completely.
Wrap each loaf tightly in plastic wrap and keep it at room temperature.
The flavor and texture are often even better after resting overnight.
Storage
Store the completely cooled loaf in an airtight container or wrap it tightly.
At room temperature, it will generally keep well for approximately 3–4 days.
For longer storage, refrigerate the wrapped loaf for up to 1 week.
Allow refrigerated slices to come closer to room temperature before serving for the best texture.
Reheating
Chocolate loaf is delicious at room temperature, but individual slices can also be gently warmed.
Place one slice in the microwave for approximately 10–15 seconds.
Avoid overheating, as too much heat can dry the cake.
Freezing
These loaves freeze very well.
Allow them to cool completely before freezing.
Wrap each loaf tightly in plastic wrap, followed by aluminum foil or a freezer-safe bag.
Freeze for up to 3 months.
To thaw, place the wrapped loaf in the refrigerator overnight or leave it at room temperature for several hours.
For convenience, you can also slice the loaf before freezing and separate the slices with parchment paper.
Common Mistakes to Avoid
Overmixing the Batter
Mix only until the ingredients are combined. Excessive mixing can create a dense texture.
Using Cold Ingredients
Very cold eggs and buttermilk may not combine as smoothly with the oil. Room-temperature ingredients are preferable.
Overbaking
Start checking the loaves around 45 minutes. A toothpick should come out with a few moist crumbs.
Cutting Too Soon
A freshly baked chocolate loaf is fragile. Allow it to cool completely for cleaner slices.
Filling the Pans Too Much
Divide the batter evenly between the two loaf pans and leave enough room for the cakes to rise.

Frequently Asked Questions
Can I make this recipe as one large loaf?
The recipe is designed for two 9 Ă— 5-inch loaf pans. Baking all of the batter in one pan can result in an underbaked center and an overbaked exterior, so two pans are recommended.
Can I use milk instead of buttermilk?
Yes. Use regular milk combined with 1 tablespoon vinegar or lemon juice per cup of milk, and allow it to stand for about 5 minutes.
Why is the batter so thin?
The hot water creates a relatively thin batter. This is intentional and helps produce a moist, tender chocolate crumb.
Can I leave out the chocolate chips?
Absolutely. The cocoa powder provides the primary chocolate flavor, so the loaves will still be delicious without the chips.
Can I use dark chocolate chips?
Yes. Dark chocolate chips are an excellent choice if you prefer a less sweet, more intense chocolate flavor.
How do I get clean slices?
Cool the loaf completely before cutting. Use a sharp serrated knife and wipe the blade clean between slices.
