Coconut Flour Lemon Raspberry Cake (Paleo, Keto)

Many of you know I have a home keto bakery, soon to be baking out of a commercial kitchen. I have baked over 5,000 grain free cupcakes in the last year. Thus, I develop new recipes weekly!

Keto Lemon Raspberry Cake

Most of my baked goods are made with a combination of almond flour and coconut flour, but I wanted to see if I could do a great coconut flour only cake for those who can’t eat tree nuts. 

The texture on this coconut flour lemon raspberry cake is fluffy and there is a slight flavor of coconut even though that is the only flour in this cake. It’s the lemon flavor that comes forward loud and clear, followed by the tart raspberries.

Naturally low in carbs, low in calories, and with no nuts, it fits a healthy life style.

You can make this recipe into muffins, a skillet cake, or use a 9 inch round cake pan.

What is difference between coconut flour and almond flour in grain free baking? 

Coconut flour absorbs liquid but with proper ratios, bakes just like almond flour. However, in some recipes, you might taste coconut and that might be off putting for some. In my almond flour raspberry muffin here, which does have a little bit of coconut flour, you won’t taste it all. In this recipe, the lemon takes over and there is hardly any coconut flavor.  

I buy this brand of coconut flour here on Amazon. 

How to substitute almond flour in this recipe if you want less of a coconut flavor.

  • Substitute 2 1/2 cups of almond for 1/2 cup of coconut flour. 
  • Retain the 2 tablespoons of coconut flour.

What sweetener do I use for Lemon Raspberry Mufins?

I use Swerve Granulated for the cake and Swerve Confectioner’s for the glaze. I wrote an article here as to why this is my sweetener of choice. Zero calories. Zero net carbs that can be processed.

Why do I use sour cream?

I find the fat in the sour cream improves the texture in grain free baking. You could skip it and add another 1/4 cup of milk of choice (almond milk, coconut milk). 

Why do I use xanthan gum?

Xanthan gum, found in many foods you eat like cream cheese, helps to bind alternative flours. You can leave it out, but your cake may tend to fall apart more.  I use this brand.

Why do I use avocado oil instead of butter?

Oil makes the cakes fluffier. I stream that oil in slowly to very whipped eggs and the result is a fluffy cake texture you will love.

What is the nutrition value of Coconut Flour Lemon Raspberry Muffins?

A Muffin or 1/12 of a cake is 167 calories, 2 net carbs. 

How can I find your bakery?

The Spinach Tiger Bakery is a home cottage bakery located in Franklin Tennessee. We deliver to Franklin and Nashville on Saturdays. We will be soon baking in a commercial kitchen.

  1. I am enjoying your Gluten Free recipes!!

    My problem is that I am now sensitive to eggs. I have used the Eggs substitute, juice from canned chickpea or ground flax seed for some recipes but with no more than two eggs required. Do you have any other ideas of what I could use?

    Many thanks for all your work and passing on such great information.
