A bright tasting lightly spiced cake perfect for spring!



2 1/2 cups fine almond flour

1/2 cup tapioca flour/starch

2 Teaspoons baking powder, see notes

1 Teaspoon baking soda

1/2 Teaspoon sea salt

2 Tablespoons lemon zest, grated with a microplane

1 Teaspoon ground cardamom

1/2 Teaspoon ground nutmeg

1 1/2 cups grated zucchini

2 eggs

1/2 cup honey, see notes

1/3 cup avocado oil

1 Tablespoon vanilla extract

1/2 Teaspoon almond extract


1/4 cup coconut butter, at room temperature

2 Tablespoons freshly squeezed lemon juice

2 Tablespoons honey

Pinch of sea salt

24 Tablespoons water


Preheat the oven to 350ºF and line the bottom of a 9″ springform pan with parchment paper. Lightly oil the pan and the paper at the bottom, then set the pan aside.

In a medium sized mixing bowl, mix together the almond flour, tapioca, baking powder, baking soda, sea salt, lemon zest, cardamom, and nutmeg until completely combined. Add the grated zucchini and mix just until the zucchini is coated by the flour mixture.

Add the eggs, honey, avocado oil, and vanilla and almond extracts. Mix just to combine and pour the cake batter into the prepared pan.

Bake for 20 minutes, then cover the top of the cake with a small piece of foil creating a tent. Continue to cook for another 35-40 minutes, (for a total of 55-60 minutes) or until the cake is puffed in the middle and a toothpick inserted comes out with just moist crumbs.

Remove the cake from the oven and place it on a cooling rack for 10 minutes. Then carefully loosen the sides of the cake with a butter knife and remove the side of the springform pan.

For the frosting, melt the coconut butter in a small saucepan over low heat. When the coconut butter is melted, whisk in the lemon juice, honey, sea salt, and 2 tablespoons of the water. Don’t worry if the frosting breaks or seizes up, just whisk in a bit more water until it’s smooth again, (refer to the photo in the post). Drizzle the frosting over the cake using a spoon, or place it into a squeeze bottle if you’d like nice clean lines across the cake.

From here you can serve it off the bottom of the springform pan, or using 2 or more spatulas carefully slide them under the parchment paper of the cooled cake, and transfer it to a cake stand. It’s best not to move the cake before it’s completely cooled unless you have 2 people and several spatulas (I’ve used 4) under every single part of the cake as it’s not sturdy enough to transfer when hot or warm. This cake keeps well at room temperature for 3 days.


Baking powder can have all sorts of additives, and isn’t always gluten free or paleo. To be safe, you can make your own by mixing together 1 part baking soda to 2 parts cream of tartar, and use the mixture right away.

If your honey isn’t liquid, heat it over low heat just enough to liquify it, but don’t let it get hot.
