Which low-carb flour is best for cupcakes?
I often develop healthy low-carb recipes using coconut flour more than almond flour. Why? If you are new here, you need to read this page – Ultimate Guide To Coconut Flour vs Almond Flour.
I love using coconut flour in low-carb recipes. Coconut flour is light, cheap, lower in carbs, and lower in inflammatory omega 6 compared to almond flour. Just take a look at the table in my ultimate guide.
Baking low-carb recipes using coconut flour does take some getting used to, but once you get the hang of it – wow. It is so versatile. Read all my tips and tricks in my Ultimate Guide.

If you have been here for a while, you will know my website is based on Real Food, Real Easy. These healthy low-carb blueberry cupcakes are no exception.
This easy sugar-free and gluten-free cupcake recipe only needs a few simple ingredients that you can find at your local grocery store.
- Eggs – whole fresh eggs.
- Butter – you can use salted butter or unsalted butter, then you can adjust the cupcake batter with a pinch of salt as required.
- Coconut flour – see notes above for swapping with almond flour.
- Baking powder – not to be confused with baking soda.
- Vanilla – vanilla extract, vanilla pods, or vanilla essence.
- Sugar-free sweetener – use your favorite sweeteners such as erythritol granules, monk fruit sweetener, allulose, xylitol, or stevia powder.
- Fresh berries.
TOP TIP: For those of you unaccustomed to using coconut flour, and the large number of eggs that are required – please, please, please taste before baking. The trick to avoiding an egg or subtle coconut flavor is to use lots of flavorings.
So make sure your batter is sweet enough, has enough vanilla, and enough lemon. I guarantee you will notice the difference. And mix well. No one wants a lump of coconut flour inside their cupcake.
