Ingredients

For the Cake

• 3/4 cup All-Purpose Flour
• 1/2 cup Granulated Sugar
• 1/4 cup Unsweetened Cocoa Powder
• 1/2 tsp Baking Soda
• 1/4 tsp Baking Powder
• 1/4 tsp Salt
• 1 large Egg
• 1/4 cup Buttermilk
• 1/4 cup Warm Water
• 2 tbsp Vegetable Oil
• 1/2 tsp Vanilla Extract
• Nonstick Cooking Spray

For the Chocolate Ganache

• 3 oz Semi-Sweet Chocolate, finely chopped
• 1/4 cup Heavy Cream
• 1 tsp Unsalted Butter

How To Make

Step 1

In a large bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt until well combined with no lumps of cocoa remaining.

Step 2

In a separate bowl, whisk the egg, buttermilk, warm water, vegetable oil, and vanilla extract until smooth. Pour the wet ingredients into the dry ingredients and stir until just combined into a smooth, thin batter. Do not overmix.

Step 3

Spray a 6-inch round cake pan with nonstick cooking spray and line the bottom with a circle of parchment paper for easy removal. Pour the batter into the prepared pan.

Step 4

Preheat the air fryer to 310 degrees F. Carefully place the cake pan into the air fryer basket. Cook for 25 to 30 minutes, until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

Step 5

Remove the pan from the air fryer and let the cake cool in the pan for 10 minutes. Then turn it out onto a wire rack to cool completely before adding the ganache.

Step 6

While the cake cools, prepare the chocolate ganache. Place the finely chopped semi-sweet chocolate in a heatproof bowl. Heat the heavy cream in a small saucepan until it just begins to simmer, then pour it over the chocolate. Let it sit for 1 minute, then add the butter and stir slowly from the center outward until completely smooth and glossy.

Step 7

Place the cooled cake on a serving plate and pour the ganache over the top, letting it drip down the sides naturally. Allow the ganache to set for about 15 minutes before slicing and serving.

Tips

Use a 6-Inch Pan That Fits

Before you start, make sure your 6-inch round cake pan actually fits inside your air fryer basket with a little space around the edges. Air needs to circulate around the pan for the cake to bake evenly.

If the pan sits too snug against the walls of the basket, the outside of the cake will cook faster than the center. You’ll end up with dry edges and a raw middle.

If you don’t have a 6-inch cake pan, a 6-inch springform pan works great too and makes it even easier to get the cake out in one piece.

Keep the Temperature at 310°F

Air fryers cook with intense circulating heat, so baking at a typical oven temperature like 350°F will burn the top of the cake before the inside is done. That’s why 310°F is the sweet spot for this recipe.

If you notice the top browning too fast around the 15-minute mark, loosely place a small piece of foil over the pan for the rest of the cook time. Don’t wrap it tightly – just rest it on top so air can still flow.

Use Warm Water, Not Hot

The recipe calls for warm water for a reason. Warm water helps the cocoa powder dissolve better into the batter, which gives you a richer chocolate flavor and a smoother texture.

But don’t use hot or boiling water. If the water is too hot, it can partially cook the egg when you mix everything together, and you’ll get little scrambled bits in your batter. Aim for water that feels warm to the touch, like bath temperature.

Frequently Asked Questions

What size air fryer do I need for this cake?

You need an air fryer that can comfortably fit a 6-inch round cake pan inside the basket with a little space around the edges for air to circulate. Most air fryers that are 3.5 quarts or larger will work just fine.

If you are not sure whether your pan fits, place it inside the basket before you start and make sure there is at least a small gap on all sides. Without that airflow, the cake will not cook evenly.
