- 1 cup buttermilk: Provides a tender crumb; you can use oat or almond milk mixed with vinegar as a dairy-free option.

- 1 ½ cups unsalted butter, room temperature: Essential for a velvety frosting.
- ¾ cup natural unsweetened cocoa powder: Used for the frosting, adding rich chocolate flavor.

- ¼ tsp salt: Just a pinch to balance the sweetness.
- 2-4 tbsp heavy cream: Adjusts the consistency of the frosting for your perfect texture.
How to Make The Best 9×13 Chocolate Cake from Scratch
- Preheat the oven: Start by preheating your oven to 350ºF (180ºC). Grease or line a 9×13 inch baking pan for easy removal.
- Combine dry ingredients: In a large mixing bowl, whisk together 2 cups all-purpose flour, ½ cup unsweetened natural cocoa powder, 1¾ cups granulated sugar, 2 tsp baking powder, ½ tsp baking soda, and 1 tsp salt until fully combined.
- Mix wet ingredients: In another bowl, whisk together ½ cup vegetable oil, 3 oz melted bittersweet chocolate (cooled), 3 large eggs, 1 cup buttermilk, ½ cup hot strong coffee, and 1 tsp vanilla extract until everything is nicely blended.
- Combine the mixtures: Gradually fold the dry mixture into the wet mixture until just combined. Be careful not to overmix, as this can make the cake dense.
- Prepare the batter: Pour the batter into your prepared 9×13 inch pan, spreading it evenly for uniform baking.
- Bake the cake: Place in the oven and bake for 30-35 minutes. Keep an eye on it and start checking for doneness around 28 minutes by inserting a toothpick in the center; it should come out clean.
- Cool the cake: Once baked, allow the cake to cool completely in the pan before frosting. This prevents melting off the frosting or creating a mess.
- Make the frosting: Beat 1 ½ cups unsalted butter using a hand mixer for about 2 minutes until it’s smooth and creamy. Then, add ¾ cup cocoa powder, 1 tsp vanilla, and ¼ tsp salt; mix on low until combined.
- Add powdered sugar: Gradually add 3 cups of powdered sugar, mixing on low speed after each addition to keep the counter clean.
- Adjust frosting consistency: Pour in 2 tablespoons of heavy cream and beat on medium speed for around 1 minute until fluffy. Feel free to add more powdered sugar for thickness or milk for a lighter spread.
- Frost the cake: Once the cake is fully cooled, spread your luxurious chocolate frosting evenly over the top.
Storing & Reheating
Store your chocolate cake at room temperature for about 2-3 days, tightly wrapped to keep it fresh. For longer preservation, refrigerate it in an airtight container for up to a week. If you’re looking to prolong it further, you can freeze individual slices wrapped in plastic wrap and foil for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator or at room temperature, then warm it briefly in the oven at 350°F for about 10 minutes to revive its moist texture.
Chef’s Helpful Tips
- Avoid overmixing: Mix just until combined to keep your cake fluffy.
- Use room temperature ingredients: They blend better, giving a more even texture. Let eggs and butter sit out for about 30 minutes before use.
- Double-check your oven’s temperature: An oven thermometer can help ensure it’s accurate, as baking is a science.
- Let it cool properly: Allowing your cake to cool in the pan helps it set and prevents crumbling when you frost it.
- Frosting adjustments: If your frosting seems too thick, add more heavy cream a tablespoon at a time to achieve your desired consistency.
This rich and moist chocolate cake truly delivers, offering a perfect blend of flavors and textures that make it a timeless favorite. Not only is this recipe incredibly easy to master, but it also invites you to experiment with flavor combinations or toppings. You might consider adding chocolate chips for an extra treat or swapping out the frosting for something fruity. The possibilities are as vast as your imagination!
Recipe FAQs
Can I make this cake ahead of time?
Yes! This cake can be baked a day or two in advance. Just store it in an airtight container and frost it closer to serving time to keep it fresh.
Can I substitute the buttermilk?
Absolutely! If you don’t have buttermilk, you can create a quick substitute by mixing 1 cup of regular milk with 1 tablespoon of white vinegar or lemon juice, letting it sit for about 5-10 minutes.
How can I make this cake healthier?
You can reduce the granulated sugar slightly and use whole wheat flour in place of all-purpose flour. Additionally, you can opt for a dark chocolate knew frosting, using avocado or Greek yogurt as a base.
Why does my cake sink in the middle?
A common reason for sinking is underbaking. Ensure you bake the cake until it is set and a toothpick comes out clean. Also, check your oven temperature for accuracy, as baking too low can cause the cake to sink.
