This Keto Snickerdoodle Skillet Cookie has 4g net carbs per serving making it a delicious treat for a low-carb diet!
I've always loved snickerdoodles. The chewy Keto Snickerdoodle Skillet Cookie flaked with cinnamon and topped with a crunchy cinnamon-sugar topping is one of my favorite holiday treats. This sugar-free version is equally delicious from what I remember minus the sugar crash.
Did you know that snickerdoodles are a traditional Dutch-German food? Some food historians say that their name comes from the German term Schnecke Knödel which is translated as “snail dumpling.” Others say that “snicker” comes from the Dutch word snekrad or the German word schnecke, both of which refer to a small, snail-like shape. 
I don't know about you but I think snickerdoodle sounds a heck of a lot more appetizing than "snail dumpling", ha!
- unsalted butter - we use unsalted butter because that allows us to precisely tailor the correct amount of salt in a recipe. All of our recipes always use unsalted butter.
- egg - we always use large eggs and try to source organic pastured eggs for animal welfare and health reasons.
- pure vanilla extract or bourbon vanilla also works great too!
- brown erythritol - we use Swerve
- almond flour - Bob's Red Mill Super-Fine Almond Flour is our go-to
- ground cinnamon - did you know that all cinnamon is not created equal
- sea salt - contains way more trace minerals than regular table salt!
- baking powder - make sure it's gluten-free if that's important to you
- granulated erythritol - we use Swerve
What size skillet should I use?
An 8" cast iron skillet works perfectly for this recipe.
Can I make these into normal snickerdoodle cookies?
I wouldn't see why not! Just use a 2 tablespoon scoop for the dough and bake them for 7-10 minutes.
Can I use coconut flour?
We haven't tested this recipe with coconut flour but this how-to substitute coconut flour for almond flour guide may be helpful if you want to swap it out. If you give it a try, leave a comment below for others in the same boat.
