Ingredients

For the Cake Batter:

  • 4 medium eggs (room temperature)
  • 4 tbsp unsalted butter (60g, melted and cooled)
  • 2 cups fine shredded unsweetened coconut (approx. 160g)
  • 2 tbsp stevia baking blend or erythritol blend (adjust to personal sweetness preference)
  • 2 tsp baking powder
  • 1 tsp organic apple cider vinegar
  • 2/3 cup whole-milk Greek yogurt (approx. 150g)
  • 1/2 tsp pure vanilla extract
  • A generous pinch of Himalayan pink salt
  • 2 tbsp unsweetened cocoa powder (reserved for the chocolate batter)

For the Silky Chocolate Glaze:

  • 4 tbsp virgin coconut oil
  • 4 tbsp raw cacao powder or unsweetened cocoa powder
  • 4 tsp allulose or 3 tsp powdered stevia baking blend
  • A pinch of pure vanilla extract and fine salt
  • Optional: 20g of 85%+ dark chocolate melted in for an extra rich, velvety gloss
  • Optional Garnish: Crushed toasted hazelnuts for garnish

Step-by-Step Instructions

  1. Prep the Pan: Preheat your oven to 170°C (340°F). Lightly grease an 8-inch round cake pan and line the bottom with parchment paper.
  2. Combine Dry Ingredients: In a mixing bowl, combine the shredded coconut, sweetener, baking powder, and salt. Stir until uniform.
  3. Whisk Wet Ingredients: In a separate bowl, whisk together the eggs, melted butter, Greek yogurt, apple cider vinegar, and vanilla until smooth and creamy.
  4. Bring Batter Together: Fold the wet ingredients into the dry coconut mixture. Mix thoroughly until a thick batter forms, then let it rest undisturbed for 2 minutes to allow the coconut to absorb moisture evenly.
  5. Separate the Batters: Divide the batter evenly into two separate bowls. Keep one bowl as vanilla. Add the 2 tablespoons of cocoa powder to the second bowl and blend well. (Tip: If the cocoa batter feels noticeably stiffer, blend in 1 extra tablespoon of Greek yogurt.)
  6. Create the Zebra Swirl: Dollop one generous spoon of vanilla batter straight into the center of the prepared pan. Spoon one dollop of chocolate batter directly into the center of the vanilla batter. Do not spread or smooth with a knife; simply repeat alternating spoons into the center—the batter will naturally spread into gorgeous concentric zebra rings.
  7. Bake: Bake at 170°C (340°F) for 30 to 40 minutes, until the cake is set and a wooden skewer inserted into the center comes out clean.
  8. Cool: Allow the cake to rest in the pan for 15 minutes, then transfer to a wire rack to cool completely before glazing.
  9. Glaze & Serve: Warm the coconut oil on gentle low heat. Whisk in cacao powder, sweetener, vanilla, and salt until glossy (stir in the dark chocolate pieces if using). Drizzle generously over the cooled cake and top with chopped hazelnuts.

💡 Ketoavie Pro Tips & Storage

  • Coconut Texture Matters: Be sure to choose finely shredded unsweetened desiccated coconut, rather than wide sweetened baking flakes, to achieve a soft, cake-like crumb.
  • Gentle Mixing: Avoid overworking the batter after the coconut is incorporated, which can release excess natural oils.
  • Sweetener Adjustments: If you are using concentrated pure stevia drops or pure powder, reduce to roughly 1 teaspoon to prevent overwhelming bitterness.
  • Storage: Store cake slices in an airtight container in the refrigerator for up to 3 days, or freeze individual pre-sliced portions between parchment sheets for up to 2 months.
