Keto Skillet Cookie Recipe

This keto skillet cookie is rich, chewy, and baked right in a cast iron skillet for crisp edges and a soft, gooey center. Made with peanut butter, chocolate, and almond flour, it’s an easy dessert that feels indulgent and perfect for sharing.

Skillet cookies are all about texture. Crisp edges, a soft center, and that just baked warmth that makes them hard to resist. This keto skillet cookie delivers all of that with simple ingredients and minimal prep.

Baking the cookie in a skillet not only makes it visually impressive, but it also helps the cookie cook evenly while staying tender in the middle.

What Is a Keto Skillet Cookie?

A keto skillet cookie is a single large cookie baked in a cast iron skillet instead of portioned cookies. The skillet creates more surface contact, which means better browning around the edges while keeping the center soft.

This style of cookie is meant to be sliced or scooped and served warm, often with ice cream or toppings.

Why Baking a Skillet Cookie Works

The cast iron skillet holds heat evenly and retains it well, which helps the cookie bake consistently from edge to center.

Because the dough is thicker than traditional cookies, baking it as one large cookie prevents overbaking and keeps the texture chewy instead of dry.

Ingredients for Keto Skillet Cookie

• Almond Flour – I use a fine almond flour in place of traditional flour in this cookie. You can substitute coconut flour if desired, but use 1/2 cup less (coconut flour absorbs moisture differently), and it may come out a little more crumbly.
• No Sugar Added Peanut Butter- as I mentioned above, choose a no-sugar-added brand of peanut butter. If you prefer almond butter or other nut butters, you can sub as desired.
• Eggs – Eggs work best at room temperature. I like to whisk them into the peanut butter mixture as well. They will act as a binding agent for the almond flour.
• Butter- Softened and salted butter works best. Do not melt the butter!
• Low Carb Sweetener – Choose a sweetener you prefer. I used granulated allulose because I like the effect when baking, and it doesn’t have an aftertaste to me.
• Baking Powder- Leavening agent.
• Xanthan Gum- This works really well to promote a chewier texture to the cookie. When you remove gluten, you lose that effect, and this helps! You can sub with cornstarch or arrowroot powder, too.
• Keto Chocolate Chips or Dark Chocolate- I use Lilly’s brand or Choc Zero. A solid dark chocolate would work too. Use what fits your diet and macros!

How to make a keto skillet cookie:

This recipe follows a very similar process to most cookie doughs (keto or not). Start by always combining your dry ingredients (almond flour, sweetener, baking powder, xanthan gum) and whisk together until combined.

Take your softened butter and no-sugar added peanut butter and whisk that together in a separate bowl. Then beat in the eggs, one at a time.

Fold the peanut butter mixture into your dry ingredients. It will start to look like wet sand, then become a thicker cookie dough base.

Finally, add in your chocolate chips and reserve a small amount to push directly into the top to make the cookie skillet look pretty and presentable.

How to Bake a Skillet Cookie in the Oven

Preheat the oven to 350 degrees Fahrenheit. Lightly grease an 8-inch cast-iron skillet if needed.

Transfer the cookie dough into the skillet and spread it evenly across the pan. Press the reserved chocolate chips gently into the surface.

Bake for 18 to 20 minutes until the edges are lightly golden, and the center is set but still soft. The cookie will continue to firm up slightly as it cools.

For mini cast iron skillets, reduce the bake time to about 8 to 10 minutes.

Other helpful recipe notes:

• This recipe will not work as individual cookies. You can swap out the skillet for an 8×8-inch pan and make them into bars, but a rolled cookie will not form the same way.
• Make sure you’re using a seasoned cast iron skillet. You can also spray the skillet to help prevent sticking.
• Pair this cookie with my delicious No Churn Keto Ice Cream or even some homemade keto caramel sauce.
• This is a lower-carb cookie, but it is still high in fat. The full nutritional information (fat content, protein, sugars, and net carbs) is listed below.
