Ingredients
  

  • 2 cups blanched almond flour
  • 2 tablespoons coconut flour
  • 1 tablespoon baking powder (aluminum-free)
  • 1/2 teaspoon fine sea salt
  • 1 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/2 cup granulated erythritol or allulose (or your preferred keto granulated sweetener)
  • 3 large eggs, room temperature
  • 1/2 cup unsweetened almond milk (or other low-carb milk)
  • 1/3 cup melted unsalted butter or coconut oil, slightly cooled
  • 1 teaspoon vanilla extract
  • 1 teaspoon apple extract (optional but recommended for stronger apple flavor)
  • 1/2 cup finely chopped apple (about 1 small apple; peel if you like)
  • 2 tablespoons lemon juice (to toss with the apple and brighten flavor)
  • Optional topping: 2 tablespoons sliced almonds or a sprinkle of granular sweetener and cinnamon

Method
 

  1. Prep the pan and oven: Heat the oven to 350°F (175°C). Line an 8-inch round cake pan with parchment and lightly grease the sides.
  2. Prepare the apple: Finely chop the apple. Toss with the lemon juice and 1 teaspoon of the sweetener. Set aside to let the juices mellow.
  3. Combine dry ingredients: In a large bowl, whisk almond flour, coconut flour, baking powder, salt, cinnamon, nutmeg, and remaining sweetener until evenly mixed.
  4. Whisk the wet ingredients: In a separate bowl, whisk eggs, almond milk, melted butter, vanilla, and apple extract (if using) until smooth.
  5. Bring it together: Pour the wet mixture into the dry. Stir until just combined. The batter will be thicker than traditional cake batter—more like a soft scoopable dough.
  6. Fold in the apple: Gently fold in the chopped apple and any accumulated juices. Avoid overmixing so the cake stays tender.
  7. Fill the pan: Spread the batter into the prepared pan and smooth the top. If using, sprinkle sliced almonds or a light dusting of granulated sweetener and cinnamon over the surface.
  8. Bake: Bake for 28–35 minutes, until the top is golden and a toothpick comes out mostly clean with a few moist crumbs. Do not overbake.
  9. Cool: Let the cake cool in the pan for 15 minutes. Run a knife around the edge, then lift it out using the parchment. Cool fully on a rack before slicing for the cleanest cuts.
  10. Serve: Enjoy plain, with a dollop of unsweetened whipped cream, or a dusting of powdered erythritol for a bakery-style finish.
