Keto Lemon Cookies: Thick and Soft


In the summer and spring months, there is nothing better than citrus! Maybe I’m just a stereotypical Floridian, but I love the refreshing sweet-tanginess of citrus!

If you’re anything like me and you love citrus too, you will adore these keto lemon cookies!

Some of our favorite citrusy recipes are our Low Carb Orange Creamsicle CakeCreamy Keto Orange Creamsicle Ice Cream, and Sugar-Free Keto Lemonade! If you are craving anything with citrus this summer, be sure to check out these great recipes.

Creating this recipe, I had really high hopes. Of course I always expect everything we make to be great, I was especially excited for this one (maybe because I love citrus… did I already mention that?).

When these finally came out of the oven and I first smelled them, I knew they would be delicious!

My tastebuds definitely confirmed what my nose already knew… these keto lemon cookies came out so great!

These sugar free lemon cookies turned out exactly how we hoped they would! 

I modeled the thickness and softness of this cookie after our Thick and Soft Keto Snickerdoodle Cookies and I think they turned out with the same consistency and feel.

If you enjoyed our keto snickerdoodles, you will definitely love these keto lemon cookies!!

Making Thick and Soft Keto Cookies

Maybe the most important ingredient that we used for these keto lemon cookies is, well, lemon. We opted to use fresh lemon juice instead of bottled, though bottled lemon juice would work fine as well.

The benefits of fresh lemons are similar to the benefits of using any fresh ingredient while cooking. Usually, fresh lemons are more flavorful, have no preservatives or additives, and just taste better overall.

Another great benefit of using fresh lemons is lemon zest. We zested a little bit of lemon for these keto lemon cookies and I think it added to the delicious flavor of these cookies!

In addition, one more important ingredient in these cookies is cream of tartar. Cream of tartar is one of those things that I had never heard of until I started baking frequently.

Basically, cream of tartar is an ingredient that helps these cookies to rise while they bake, and it also prevents them from burning on the bottom while they bake.

Cream of tartar is not necessarily required to make these keto lemon cookies, but it will surely make your cookies turn out even better! 

If you don’t have any in your pantry and really want to whip up a batch of these cookies, don’t fret!

One of the great things about these cookies, and most of our recipes for that matter, is that they are totally customizable and can be adapted to suit whatever you love.

If lemon isn’t your thing, or if you just want to try something new, you can swap out lemon for orange or lime.

Certain citrus fruits contain some sugar, but in small amounts, it should not affect your insulin levels or affect your state of ketosis (unless you eat the entire batch of cookies… then maybe).

No matter what citrus you decide to use, these keto lemon cookies will turn out looking great and tasting delicious!

How To Make Keto Lemon Cookies

  1. In a large bowl, combine all dry ingredients.
  2. In a separate bowl, combine together all wet ingredients, including lemon zest.
  3. Combine wet and dry ingredients into one bowl.
  4. Scoop out cookies into 1×1 inch balls.
  5. Slightly flatten on a parchment paper lined baking sheet. Note: The cookies won’t rise very much while baking so form them into the desired shape before baking.

Keto Glaze And Other Ideas

The most important ingredient when making the keto friendly glaze is definitely Lakanto’s Powdered Monkfruit. It tastes, looks, and works just like powdered sugar, just… well, without the sugar!

If you want to give Lakanto’s Powdered Monkfruit a try, or if you want to check out any of their other great products, check out their website HERE.

In addition to powerderd Monkfruit, we used almond milk to create the glaze. It worked fine and tasted great, but if you are worried about an almond flavored icing, you have other options!

You can create a glaze using any other keto friendly milk, or you could also make a lemon glaze using powdered sweetener and about a tablespoon of lemon juice and a tablespoon of butter. This will obviously result in a more tangy flavor, but there is nothing wrong with that!

Finally, you could also choose to make lemon crinkle cookies! To do this, all you will need to do is roll your cookie dough in some powdered sweetener before you bake them!

The options are endless!

  • Zester – It’s important to have a good lemon zester when you need it! This is a great one to have.
  • Cream of tartar – I love using cream of tartar in certain cookie recipes as it helps the cookies to rise more and helps gives a more lighter texture.
  • Fresh lemon – Be sure to use fresh lemon juice instead of the fake stuff you find at the grocery store! It truly makes a difference when you use the real stuff when it comes to making these cookies.
  • Lemon Zest – lemon zest is essential for increasing maximal flavor that you’ll want!
  • Lemon Extract – Using lemon extract rather than vanilla extract is a smart move! It’s an extra flavor addition that you don’t want to miss!
