How To Make Easy Air Fryer Walnut Cake

Mixing walnut cake batter with flour, sugar, eggs, vanilla, oil, and milk in a bowl after preparing a parchment-lined 7-inch baking pan.

Step One: Grease a 7-inch baking pan thoroughly and line the bottom with a circle of parchment paper.

Step Two: In a mixing bowl, whisk together the flour, sugar, and baking powder. Add the eggs and vanilla, mixing gently until combined, the batter will be quite thick at first. Pour in the oil and milk, then whisk until the batter becomes smooth and well blended.

Step Three: Fold the walnuts into the batter and stir gently until they are evenly distributed, being careful not to overmix. Pour the batter into the prepared pan and place it in the air fryer basket. Bake at 340°F for about 40 minutes, or until a wooden skewer inserted in the center comes out clean. Begin checking for doneness around 32–35 minutes and continue baking if needed.

Step Four: Allow the cake to cool completely before adding the frosting. In a large bowl, beat the butter, walnuts, and icing sugar with an electric mixer until light and fluffy. Slowly pour in the milk while mixing on high speed, continuing to beat for 2-3 minutes until the frosting becomes smooth, airy, and slightly increased in volume.

Step Five: Level the cake by carefully slicing off the top with a serrated knife. Save the trimmed piece for decoration or enjoy it as a tasty snack.

Step Six: Slice the cake horizontally into two even layers. Set the bottom layer on a serving plate, spread ⅓ to ½ of the frosting over it, then place the second layer on

Step Seven: If you like, save about a tablespoon of frosting and combine it with crumbs from the trimmed cake top. Roll the mixture into small balls to create truffles for decorating your cake.

Easy Air Fryer Walnut Cake Recipe Tips

  • Use Room Temperature Ingredients: Eggs, milk, and butter mix more evenly, giving a smoother, fluffier batter.
  • Don’t Overmix the Batter: Once the flour is added, whisk gently to avoid a dense cake.
  • Check for Doneness Early: Start testing at 32–35 minutes with a skewer to avoid overbaking.
  • Rotate the Pan if Needed: Air fryers can have hot spots; gently rotate halfway through baking for even browning.
  • Cool Completely Before Frosting: Frosting slides and melts if the cake is warm, so let it cool fully for best results.
  • Optional Nut Boost: Toast walnuts lightly before folding in for extra crunch and deeper flavor.

Storing, Freezing and Make Ahead Instructions

  • Storing Instructions: Store the cooled walnut cake in an airtight container at room temperature for up to 3 days. Keep it away from direct sunlight or heat to maintain freshness and texture.
  • Freezing Instructions: Wrap the fully frosted cake tightly in plastic wrap, then in aluminum foil, and freeze for up to 2 months. Thaw in the refrigerator overnight before serving for best results.
  • Make-Ahead Instructions: You can bake the cake layers a day ahead and keep them wrapped at room temperature. Prepare the frosting separately and assemble the cake just before serving for maximum freshness.

How do I know when the cake is done? Insert a wooden skewer into the center of the cake; it should come out clean or with just a few crumbs attached.

  • 3/4 cup caster sugar
  • 2 large eggs
  • 1/2 cup milk
  • 2 teaspoons baking powder

  • 1/2 cup unsalted butter, room temperature
  • 1/2 cup ground walnuts
  • 1/2 cup icing sugar, (powdered sugar)

Instructions

  • Grease very well a 7 inch baking pan and line it with a circle of parchment paper.
  • In a mixing bowl whisk together the 1 1/2 cup all-purpose flour, 3/4 cup caster sugar and 2 teaspoons baking powder. Add the 2 large eggs and 1 teaspoon pure vanilla extract , and stir gently.
  • The mixture will be thick. Add 1/3 cup vegetable oil and the 1/2 cup milk and continue whisking until the mixture becomes smooth.

  • Pour the batter into the prepared pan. Place the pan into the basket of the air fryer.
  • Bake the cake for about 40 minutes at 340º F or until a wooden skewer inserted in several places comes out clean. Check after at about 32-35 minutes and continue baking if it is not done yet.
  • Let the cake cool completely before assembling it. The frosting is optional: it is perfectly tasty also plain.

To Frost And Assemble:
