Ingredients

Cake Wet ingredients

  • 1 cup (250g) dairy-free milk
  • ~1 (200g) large avocado or 2 medium avocados (weighed after removing the skin and seed, note 1)
  • 1 cup (200g) granulated sugar
  • ⅔ cup (165g) neutral flavored oil
  • 3 tablespoons (45g) lime juice (note 2)
  • 1 tablespoon lime zest
  • 1 teaspoon vanilla extract (optional)
  • 1 teaspoon coconut extract
  • teaspoon green food coloring as needed (optional, note 3)

Cake Dry ingredients

Buttercream frosting

Raspberry jam filling (note 5 for store-bought jam)

Avocado ganache

To decorate (optional)

Instructions

  • Preheat your oven to 180°C (355°F). Grease or line 2 x 8 inch (20 cm) round cake pans with parchment paper.

Make the vegan avocado lime coconut cake:

  • Add all the wet ingredients to a large mixing bowl and blend with a stick blender. Alternatively, blend all the wet ingredients in a stand blender or food processor, then transfer the mixture to a large bowl.
  • Add the dry ingredients to the bowl and mix until well combined. A few small lumps are fine, as long as they aren't lumps of dry flour.
  • Divide the cake batter into your prepared cake pans.
  • Bake the cakes for around 30-35 minutes or until you can insert a toothpick in the middle and it comes out clean. A few crumbs on the toothpick are fine.
  • Allow the cakes to cool in their pans for 15 minutes. Then transfer them to a wire rack to cool completely.

Make the buttercream:

  • Add the vegan butter to a large bowl or stand mixer and beat until it is light and fluffy. Add the sugar, lime juice and vanilla extract and beat until combined. Add more sugar for a firmer frosting or more lime juice (or dairy-free milk) for a softer frosting. Set aside until needed.

Make the quick jam:

  • Add all ingredients and a dash of water to a small saucepan and stir until combined. Bring the mixture to a gentle simmer for 10 minutes while stirring and mashing the berries. Add more water for a thinner jam or cook longer for a thicker jam.
  • When the jam has thickened, set aside to cool. It will thicken more while it cools.

Make the avocado ganache (optional):

  • Melt the coconut cream in a small saucepan. Remove from the heat. Add the white chocolate and allow the mixture to sit for 5 minutes to soften the chocolate. Mix until combined.
  • Add the avocado to the mixture. Blend with a stick blender or stand blender until smooth.
  • Allow the ganache to cool until it's a drizzle consistency. If needed, add a dash of milk to thin the ganache or more coconut cream to thicken the ganache. You'll need to work with the ganache quickly.

Assemble the cake:

  • Use a serrated knife to cut the domes off the cakes, if any. Place one cake layer on a serving plate.
  • Spread or pipe around ¾ cup of buttercream on the cake. If you're using the jam, create a 'frosting dam' then spread the raspberry jam in the middle. Place the remaining cake on top. Spread around 1 ½ cups of frosting around the tops and sides of the cake.
  • Optional: Drizzle the avocado ganache down the sides of the cake. If the ganache is too thick, warm it up for a few seconds in the microwave (see the blog post for more tips). Pipe the remaining frosting on top of the cake. Decorate the rest of the cake, as desired.
  • Store the cake in an airtight container at room temperature for 1 day or in the fridge. Allow the cake to come to room temperature for 1-2 hours before serving. Leftovers will keep in the fridge for 5 days or in the freezer for 1 month.

Notes

  1. I strongly recommend weighing the avocado flesh. Avocados vary a lot in size and adding too much avocado will make the cake dense.
  2. You'll need approx 2-3 medium limes for the cake and buttercream combined.
  3. All brands of food coloring vary in intensity so you may need to adjust accordingly. If you use a green coloring gel, I suggest using less than 1/8 teaspoon. Alternatively, you can use 1/2 - 1 cup of baby spinach leaves if you don't mind a denser cake. Puree the spinach with the avocado mixture.
  4. Vegan spreadable margarine (in a tub) will create a much softer frosting. If you only have access to this, I recommend increasing the amount of powdered sugar (for stability), minimizing or omitting the lime juice and keeping your cake chilled until 1-2 hours before serving. You can also add some vegan shortening to your frosting to make it more stable.
  5. Alternatively, use 160 grams of store-bought jam and 1 1/2 tablespoons corn starch. Mix them in a saucepan and cook until thickened.
