Ingredients

Scale

For the Cake

  • 400 g dark chocolate (50-70%)
  • 6 eggs
  • Pinch of salt
  • 4 tbsp coconut oil
  • 4 tbsp oil (for example sunflower)
  • 130 g (3 dl, ⅞ cup) rice flour
  • 2 tbsp honey (optional)
  • 1 tsp instant coffee
  • ½ tsp baking soda

For the Frosting

  • 300 g (5 dl, 2 cups) cashew nuts (soaked overnight)
  • 120 g (2 dl, ½ + ⅓ cup) blueberries (fresh or frozen)
  • 1 tsp dried lavender
  • 4 tsp lime juice
  • Zest of 1 lime
  • 2 tbsp honey
  • 2 tbsp coconut oil
  • 2 dl oat yogurt

For the Filling

  • 50 g dark chocolate (70%)

Instructions

  1. Preheat oven: Set the oven to 175°C (350°F) to prepare for baking the cake layers.
  2. Melt chocolate and coconut oil: Gently melt the 400 g dark chocolate and 4 tbsp coconut oil together using a bain-marie or microwave until smooth.
  3. Whip egg whites: Separate eggs, place egg whites in a bowl with a pinch of salt, and beat until firm peaks form. Set aside.
  4. Mix cake batter: Combine egg yolks, 4 tbsp sunflower oil, rice flour, instant coffee, baking soda, and optional honey into the melted chocolate mixture. Mix thoroughly but gently.
  5. Fold in egg whites: Using a spatula, carefully fold spoonfuls of the whipped egg whites into the chocolate batter. Avoid overmixing to keep the batter light and airy.
  6. Prepare pans and bake: Line two 16 cm (6½ inch) springform pans with baking paper, grease edges, and divide batter evenly between them. Bake for 25-30 minutes or until a toothpick inserted comes out clean.
  7. Cool cakes: Remove the cakes from the oven and let them cool completely in the pans.
  8. Prepare frosting: Drain and dry the soaked cashew nuts. Combine cashews, blueberries, dried lavender, lime juice, lime zest, honey, coconut oil, and oat yogurt in a blender. Blend until smooth and creamy.
  9. Chill frosting: Refrigerate the frosting for at least 30 minutes to allow it to thicken and harden slightly.
  10. Chop chocolate filling: Roughly chop 50 g dark chocolate with a knife to create chocolate crumbs for the filling.
  11. Slice cake layers: Remove cakes from pans once cooled, level tops with a knife, then cut each cake horizontally in half, creating four layers in total.
  12. Assemble cake: Place the first cake layer on a serving plate. Spread a thin layer of frosting evenly on top and sprinkle some chocolate crumbs gently, avoiding the edges.
  13. Repeat layering: Continue layering frosting and chocolate crumbs between all cake layers. Cover the entire cake with a very thin crumb coat of frosting.
  14. Chill and finalize frosting: Refrigerate the assembled cake with remaining frosting for at least 30 minutes to set. Then frost the cake again with a thicker, smooth layer of frosting, covering top and sides fully.

Notes

  • Soaking cashews overnight ensures a creamy and smooth frosting texture.
  • Instant coffee enhances the chocolate flavor without adding a strong coffee taste.
  • Honey is optional; adjust sweetness according to preference or dietary needs.
  • Rice flour keeps this cake gluten-free while providing a delicate crumb.
  • Ensure cakes are completely cooled before layering to prevent frosting from melting.
  • Lavender used in frosting is dried; use culinary-grade to avoid bitterness or pesticide residues.
  • Store the cake refrigerated and consume within 3-4 days for best freshness.
