The Ultimate Keto Blueberry Coconut Skillet Cake!

This keto blueberry coconut skillet cake is so easy and delicious that it makes a low-carb lifestyle a breeze! It’s grain-free, nut-free, sugar-free, and keto-friendly.

The blueberries and toasted coconut flakes pair perfectly in this rich, moist, and super easy-to-make old-fashioned keto skillet cake.

Perfect for a brunch, after-school snack, or a la mode for a drool-worthy sugar-free dessert!

This keto blueberry toasted coconut cake can be made in a cake pan, cast iron skillet, or muffins, which makes it easy to customize.  

I chose to feature the recipe in a cast-iron skillet pan because I just love how well a cake bakes in it. Plus, presenting a low-carb blueberry cake in a skillet looks stunning and always turns heads!

Keto Blueberry Coconut Cake

Blueberry desserts have a special place in my heart because I used to make blueberry muffins for my friends a long time ago, and they hold many beautiful memories for me.

Since adopting the ketogenic lifestyle, if I want to enjoy blueberries in baked goods, it’s gotta be a low-carb, keto-friendly option, like this keto blueberry cake. 

So now, when I pick up a pint of blueberries, my thought process looks quite different. No longer am I thinking of how much sugar I can squeeze into a treat, winning!

Believe it or not, that used to be how this baker used to think. Now, it’s more about how I can pack the most flavor and nutrition into my goodies.

This low-carb blueberry coconut cake features good-for-you antioxidant-rich berries without compromising your carb intake.

If that’s not enough, it’s a quick dessert rich in blueberry flavor!

I find it’s perfect to pair with my morning cup of coffee or after dinner with a scoop of sugar-free vanilla ice cream as an irresistible sugar-free dessert!

What’s more, this keto blueberry coconut skillet cake is light, airy, and moist. Something you can’t say about all keto coconut cakes.

But I’ve somehow managed to crack the code on baking with low-carb keto flour, and thankfully, my treats are never dry.

I love that the flavor of coconut is amplified in this keto cake by using coconut flour and coconut flakes. It’s a coconut lover’s treat, for sure. 

How To Make Keto Blueberry Coconut Cake

This keto blueberry skillet cake is so quick and easy to make! You’ll start by simply combining your melted butter, eggs, and sugar substitute in a large mixing bowl. 

Then, add the sour cream, vanilla extract, and heavy whipping cream to this mixture and combine well.

Add in the dry ingredients, the coconut flour, ¾ cup of the coconut flakes (we’ll be using the rest later) baking powder, and salt.

Next, fold in the blueberries to the wet ingredients, spread the cake batter in your cast-iron skillet, and sprinkle the reserved toasted coconut flakes for the top of the cake.

If you don’t have a cast-iron skillet, you can bake this blueberry cake recipe in a 9-inch cake pan. Baking in the cast-iron skillet creates an incredible crust that can’t be beaten, though!

Bake until slightly golden and an inserted toothpick comes out clean, about 25 minutes, and enjoy this coffee cake!

Store any leftovers in an airtight container in the refrigerator for up to five days or freeze for up to three weeks.

The Best Sugar Substitute For Keto Baking

When it comes to choosing which sugar substitute to use for this keto skillet cake, I have several for you to choose from.  My go-to choice is  Lakanto Monk Fruit because the texture is spot-on since there is barely any aftertaste.

It is a monk fruit and erythritol blend. Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose.

That’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic index.

I’m also partial to Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.

It’s made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

Swerve is the name brand of erythritol, and it’s unlike other sugar alcohols because it has a 0 % impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure for most of my baked goods.

But if using Pyure you will want to use half the amount called for in this recipe since it’s much sweeter. 1/4 cup is enough if using this sweetener.

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda with great success. 

 Blueberry Benefits

• They are packed with a flavonoid called anthocyanin. It’s what gives blueberries their deep blue color and health benefits.
• Blueberries can enhance heart health, blood pressure, skin health, lower sugar levels, bone strength, and cancer prevention.

Coconut Prebiotic Benefits

Probiotics are the beneficial bacteria that live in the colon that help us digest and absorb the nutrients in our foods.

Most people are familiar with probiotics and their role in defending us against harmful bacteria.

However, as important as probiotics are for your gut to work properly, these friendly bacteria simply would not exist if they were not for prebiotics.

This is because prebiotics is the food that actually feeds probiotics. Without the feeding of probiotics, we can’t see the growth and repopulation in our gut.

An easy way to remember the role of prebiotics is to think of them as gut fertilizers.

Coconut meat is rich in a prebiotic fiber called inulin. Inulin is a fructan that promotes the growth of healthy bacteria in our gut.

Looking for intentional ways to add nutrition to my baked goods is now a priority. I chose to make this keto blueberry coconut cake with coconut flour because I wanted to find a delicious way to include more inulin and antioxidants into our diet.
