A certified nutritionist and self-taught chef with a love for entertaining and experimenting with food, Lolita Carrico created Ketology after struggling for years with her own hormonal changes and weight gain. After having two children, she found that managing her weight and moods became more and more of a struggle. After researching the ketogenic diet thoroughly and understanding the science and nutritional aspects, she began her keto journey in 2018. Within three months, she shed 25 pounds and her mood improved, focus sharpened and her energy was through the roof. Four years later, she has maintained a 65-pound weight loss and has learned to intuitively follow a balanced keto lifestyle without sacrificing a thing!

I obsess over lemons – they are beautiful to decorate with, so good for your body and perfect in so many sweet and savory dishes. These low carb muffins with lemon and creme fraiche (or sour cream) bring brightness and happiness in every bite!

As I’ve mentioned, I prefer combining coconut and almond flours when baking for the right consistency, and this recipe is no exception. They are easy to make and delightful for weekend brunch or to slip in as a treat with your lunch. The lemon zest is key to the flavor here – and organic lemons are pretty much a must when zesting to get the fresh zest without any waxes or preservatives.

As if the lemon doesn?t make these low carb muffins tangy enough, the creme fraiche (or sour cream) adds a mellow creaminess that helps mind the flours – coconut flour can get overly dry and then the ghee if you can get it also brings a mellow moist quality to this recipe.

Creme Fraiche and sour cream are quite similar – creme fraiche is a little thicker and less tangy – so I like it in baking however either works in this recipe! I sometimes even use only 1 or 1 1/2 cups of sweetener in the muffin portion of the recipe because the lemon glaze (which is amazing) brings a significant amount of sweetness. If you prefer muffins that aren’t overly sweet, start by trying this recipe with 1 1/2 cups vs 2 cups of sweetener.
