  • 3 eggs

  • 2 cups carrots shredded and overflowing
  • 1/2 cup walnuts chopped
  • 1/2 cup unsweetened shredded coconut
  • 2 tsp vanilla extract
  • 2 tsp cinnamon
  • 1/2 tsp salt

The Carrot Cake

  • Mix the olive oil and coconut sugar in a bowl and then stir in the starter. Add in the eggs and then the vanilla.
  • Mix in the pineapple, carrots, walnuts, and coconut.
  • Combine the flour, cinnamon, salt, and baking soda in a separate bowl.
  • Add the dry ingredients to the wet ingredients, stirring just until combined. Pour the batter into the greased round pans, distributing evenly and tapping to level.
  • Bake the cakes for 45 minutes, or until a toothpick inserted into the center comes out clean, and the sides are just beginning to turn golden brown.
  • Remove the cake from the oven and let cool on a rack completely before frosting.

The Ricotta Frosting:

  • In a mixing bowl, beat ricotta until thinned out, about 30 seconds. Mix in yogurt and honey until combined.
  • Mix in cardamom, cinnamon, and lemon juice
  • The frosting should be thick with soft peaks and a nice spreadable consistency
  • Place one cake layer on the serving tray, coat with about 1/2 of the frosting and top with the other carrot cake round. Spread the remaining frosting evenly across the cake top and sides.
  • Optionally, crush some additional walnuts and spread around the edges for garnish.


Serve the cake at room temperature. Store it in the refrigerator for up to 5 days. You can also freeze the unfrosted up to 2 months and then frost just before serving.
