Ingredients

Dry Ingredients
1 1/4 cups all-purpose flour
3/4 cup white granulated sugar
1/2 cup unsweetened cocoa powder
1/2 tablespoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon salt
Wet Ingredients
1/2 cup canola or vegetable oil
1 teaspoon pure vanilla extract
2 large eggs (room temperature)
1/2 cup buttermilk (room temperature)
1/2 cup steaming hot water (or hot coffee)
Ganache Ingredients
2 cups semi-sweet chocolate chips
1 1/4 cups heavy cream

Baking the Chocolate Cake

Preheat the Oven

Start by preheating your oven to 350°F. Prepare a 9X9-inch square baking pan by spraying it with nonstick baking spray. To ensure easy removal, line the bottom with parchment paper and spray it again.

Combine Dry Ingredients

In a large mixing bowl, whisk together the all-purpose flour, sugar, cocoa powder, baking powder, baking soda, and salt. This ensures all dry ingredients blend well to create a flavorful base.

Prepare Wet Ingredients

Next, in a separate bowl, mix the canola oil, vanilla extract, eggs, and buttermilk. As you whisk, gradually add the steaming hot water until everything is fully combined and smooth. This step infuses moisture into the cake.

Mix Batter

Now, pour the wet ingredients into the bowl of dry ingredients. Stir gently until just combined; it’s okay if a few lumps remain. Overmixing can make the cake dense, so be careful.

Bake the Cake

Pour the batter into the prepared pan. Bake in the preheated oven for 25-30 minutes. To check for doneness, insert a toothpick into the center—if it comes out clean, your cake is ready! Allow the cake to cool in the pan for about 10 minutes before moving it to a wire rack to cool completely.

Making the Chocolate Ganache

Heat the Cream

As the cake cools, let’s work on the ganache. In a medium saucepan, heat the heavy cream over medium-low heat until it’s steaming but not boiling.

Combine Chocolate and Cream

Place the semi-sweet chocolate chips in a mixing bowl. Carefully pour the hot cream over the chocolate chips and let it sit for 2 minutes. This step helps soften the chocolate.

Mix Until Smooth

Using a rubber spatula, gently stir the mixture until smooth. If you notice any chocolate chunks that aren’t melting, feel free to heat the mixture in the microwave for a few seconds—just be careful not to overdo it.

Cool the Ganache

Let the ganache sit at room temperature for about 2 hours, stirring every 20 minutes. This allows it to thicken to a pudding-like consistency. Once it’s ready, use a hand mixer to beat the ganache until it’s fluffy.

Frost the Cake

Once the cake is completely cooled, it’s time to frost! Spread the fluffy ganache evenly over the top of the cake. Allow it to set for a little while before serving; this will help the ganache maintain its shape.

Serving Suggestions

Pair this Chocolate Ganache Cake with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence. And for an added touch, sprinkle with chocolate shavings or fresh berries. This elevates both the taste and look of your dessert.

Tips for Success

Ensure your eggs and buttermilk are at room temperature; this helps the batter mix smoothly.
If you’re using coffee instead of water, it will enhance the chocolate flavor beautifully.
Be patient when cooling the ganache; it’s crucial for achieving that fluffy frosting.

Variations

Consider adding a layer of raspberry or cherry preserves between the cake and ganache for a fruity twist.
For a richer flavor profile, substitute dark chocolate chips in the ganache. This will deliver a deeper chocolate taste.

FAQs

1. Can I use cake flour instead of all-purpose flour?
Yes, using cake flour will yield a lighter texture. Just be aware that adjusting the measurements slightly may be necessary.

2. How should I store the leftover cake?
Leftover cake can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for a week.

3. Can I freeze the Chocolate Ganache Cake?
Absolutely! Just wrap the cooled cake tightly in plastic wrap and then in aluminum foil. It can keep in the freezer for up to 3 months.

4. What can I substitute for buttermilk?
To make a buttermilk substitute, mix 1/2 cup of milk with 1/2 tablespoon of white vinegar or lemon juice. Let it sit for a few minutes before using.

5. How do I know when the cake is done?
The cake is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs.
