A walnut cake made in the air fryer is a moist and flavorful dessert with a rich nutty flavor. The combination of ground walnuts and a soft, spongy cake creates a perfect balance of texture and taste. The air fryer helps achieve a tender, golden crust with a slightly crisp top, while the inside remains fluffy and delicious. This walnut cake is perfect for those who enjoy a nutty treat that’s not overly sweet but still indulgent.
Ingredients:
- 1 cup all-purpose flour
- 1/2 cup ground walnuts (you can grind them yourself or buy pre-ground)
- 1/2 cup sugar
- 1 teaspoon baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup milk (or dairy-free milk)
- 1/4 cup chopped walnuts (for topping, optional)
- Powdered sugar (optional, for dusting)
Instructions:
- Prepare the Cake Batter: In a large bowl, whisk together the flour, ground walnuts, sugar, baking powder, baking soda, and salt. In another bowl, beat together the softened butter, eggs, and vanilla extract until smooth and creamy. Gradually add the dry ingredients to the wet ingredients, alternating with the milk. Mix until the batter is smooth and well combined.
- Prepare the Air Fryer Pan: Grease a small round or square cake pan that will fit in your air fryer basket. You can also line it with parchment paper for easier removal. If you’d like, sprinkle a little flour over the greased pan to help prevent sticking.
- Pour the Batter into the Pan: Pour the batter into the prepared cake pan and smooth the top with a spatula. Sprinkle the chopped walnuts on top of the batter for added texture and flavor.
- Preheat the Air Fryer: Preheat your air fryer to 330°F (165°C) for 3-5 minutes.
- Bake the Cake: Place the cake pan in the air fryer basket and bake at 330°F (165°C) for 18-22 minutes. Check the cake at around 18 minutes by inserting a toothpick into the center. If it comes out clean or with just a few crumbs, the cake is done. If it’s still wet, continue baking for a few more minutes.
- Cool & Serve: Let the cake cool in the pan for about 10 minutes before transferring it to a wire rack. Once fully cooled, you can dust the top with powdered sugar for a decorative touch. Slice and serve.
