Coconut Lime Cake (Keto, Paleo, Dairy Free, Nut Free)


Summer seems to be birthday season around here and having a killer cake on hand is a must! This dairy-free keto cake is as good as it gets. It tastes like decadent, tropical rum cake. It’s moist, flavorful, elegant and beautiful and it’s easy to make!

I made this cake for my unsuspecting stepdad who flew to Hawaii with my mom on his birthday! We had dinner, we had cake, everyone was hooked. Then I kind of forgot about this recipe until today!

Dairy Free Keto Cake… and Paleo? and Sweetener Free too?

So I remembered this cake because it came up in a dairy-free keto facebook group… does someone have a sweetener free cake and I thought of this one. It originally only uses 1/3 cup of erythritol for the entire cake… that could easily be omitted with little change to the flavor.

Then I thought … some delicious replacements would be Primal Fuel Vanilla Collagen (adds vanilla flavor and a hint of sweetness) or MCT Oil Powder for texture!

Either way, you can’t go wrong.

The Cream… Coconut Cream

Is simple. Chill a can of full fat, good quality coconut milk overnight. Open the can while it’s still very cold. Scoop out the hard, creamy, coconut milk fat. Promptly whip that up with lime zest, pinch of salt and the optional stevia.

Whip with egg beaters until it looks whipped, fluffy and smooth. Then keep cold, in the fridge. Quickly dress the cake. Keep that cold too until ready to serve.

  • Total Time: 45 minutes
  • Yield: 2 layer 6" cake


For the Cake:

1/2 cup coconut flour

1/3 cup erythritol or other granulated sweetner (optional, see notes)

2 tsp baking powder

1/4 pinch salt

2 limes zested

4 large eggs

1/4 cup coconut oil

1/2 cup coconut milk (left over from coconut milk can) 

1/4 cup unsalted ghee, softened butter or lard


2 cans full fat coconut milk, chilled (use the cream on top) 

1 lime zest

10 drops liquid stevia or 1 tablespoon honey (optional)

pinch of salt


Pre-heat oven to 350F. Lightly grease two 6″ cake pans. 

Sift the dry ingredients (flour, sweetener, baking powder, and salt) together in a small bowl. 

In a large bowl mix with an electric hand mixer beat the eggs, milk, lime zest, coconut oil, and lard for 2-3 minutes until foamy and fluffy. 

Add the dry ingredients to wet ingredients and beat until well combined. 

Pour the cake mix into the two prepared cake pans, place them on a sheet pan and bake 25-30 minutes until a toothpick inserted comes out mostly clean.

Let the cakes cool completely before unmolding. Set them to chill while you make the coconut cream.

In a small bowl whip the coconut milk fat until with a hand mixer until smooth and whipped. Add in the lime zest, stevia if you’re using it and salt. Then use a cold metal spatula to spread some on top of one cake round in the middle.

Stack the cakes and then use the rest of the cream to frost the outside of the cake. Keep the cake chilled until ready to serve!


*Use of sweetener is optional in this recipe the natural sweetness of the coconut and lime are enough if you don’t do keto sweeteners! Alternatively, you may use raw honey if you eat honey, Vanilla Collagen Primal Fuel or MCT Oil Powder instead of the erythritol too!*
