Method: One Layer Mocha Cake

Now that you have everything ready, let’s get to baking this delicious One Layer Mocha Cake.
Step 1: Prepare the Cake Pan
Start by preheating your oven to 350°F (175°C). Grease your 9-inch round cake pan with softened butter, then dust it with flour. This will help ensure your cake releases easily after baking.
Step 2: Combine Dry Ingredients
In a large mixing bowl, whisk together 2 cups of flour, ¾ cup of cocoa powder, 1 cup of granulated sugar (reserve 1 tablespoon for later), baking powder, baking soda, and salt until well combined.
Step 3: Mix the Wet Ingredients
In another bowl, combine the room temperature eggs, dark brown sugar, vegetable oil, melted bittersweet chocolate, buttermilk, instant coffee, and vanilla extract. Mix these ingredients until they form a smooth mixture.
Step 4: Combine Wet and Dry Ingredients
Gradually add the wet ingredients to the dry mixture. Use a whisk to mix until just combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 5: Pour the Batter into the Pan
Pour the cake batter into the prepared cake pan. Gently spread it into an even layer using your rubber spatula.
Step 6: Bake the Cake
Place the cake in the preheated oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Keep an eye on it towards the end to avoid overbaking.
Step 7: Cool the Cake
Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely.
Swap Guide

If you’re looking to personalize your One Layer Mocha Cake, consider these swaps:
- Flour: Whole wheat flour can work well for a healthier option.
- Cocoa powder: Use Dutch-processed cocoa for a different flavor profile.
- Vegetable oil: Melted coconut oil can be a great alternative.
- Buttermilk: Substitute with almond milk mixed with a tablespoon of vinegar or lemon juice.
- Instant coffee: Brewed coffee can replace instant coffee for a stronger flavor.
Easy-to-Miss Gotchas
When making your One Layer Mocha Cake, keep an eye out for these common pitfalls:
- Ensure ingredients like eggs and buttermilk are at room temperature for a better emulsion.
- Do not overmix the batter; this can lead to a dense cake.
- Check for doneness a few minutes early to prevent overbaking.
- Let the cake cool completely before frosting or serving to prevent any melting or sliding.
Storing Tips & Timelines
To keep your One Layer Mocha Cake fresh and delicious:
- Store the cake in an airtight container at room temperature for up to 3 days.
- If you need to store it for longer, wrap it tightly in plastic wrap and refrigerate for up to a week.
- For longer storage, freeze the cake for up to 3 months. Thaw in the refrigerator overnight before serving.
Frequently Asked Questions
Can I use a different type of chocolate instead of bittersweet?
Yes! You can use semisweet chocolate if that’s what you have on hand. Just keep in mind it may make the cake slightly sweeter.
