👩‍🍳 Step-by-Step Instructions

1. Preheat and Prep

Preheat your oven to 350°F (175°C).
Lightly grease a 9-inch cast iron skillet or oven-safe pan with butter or coconut oil.

2. Make the Dough

In a medium bowl, mix almond flour, baking soda, and salt with a whisk.
In another large bowl, beat the butter and sweetener until airy and fluffy.
Add in the egg and vanilla extract, and mix well.
Slowly mix the dry ingredients into the wet until a soft dough forms.

3. Add Chocolate and Marshmallows

Gently fold in most of the chocolate chips and marshmallows, saving a few for topping.

4. Press and Bake

Press the dough evenly into the skillet. Dot the top with remaining chocolate and marshmallows.
Bake for 18–22 minutes, or until golden around the edges and just set in the middle.
Don’t overbake—this is best gooey!

5. Cool Slightly & Serve

Let cool for 5–10 minutes. Savor it hot straight from the pan with a spoon or cut it into pieces like a pie.

📦 Storage Tips

Fridge: Store covered in the skillet or transfer to an airtight container. Keeps for up to 5 days.
Freezer: Slice into portions and freeze in a sealed bag for up to 2 months. Reheat in the microwave or oven.

🔁 Variations

Nut-free: Try sunflower seed flour instead of almond flour (1:1 ratio).
Dairy-free: Use coconut oil or plant-based butter.
Flavor twist: Add cinnamon for a graham cracker vibe or a swirl of peanut butter before baking.
Mini version: Use ramekins for individual skillet cookies—cut baking time to 12–15 minutes.

💡 Pro Tips & Tricks

Use golden sweetener: It mimics the brown sugar flavor of traditional s’mores.
Skillet size matters: If you use a smaller skillet, reduce oven time slightly.
Don’t overmix: Just combine the dough until it comes together to keep it tender.
Top with keto ice cream: For the ultimate indulgent treat.

❓ Frequently Asked Questions

Can coconut flour be used in place of almond flour?

No, coconut flour isn’t a good 1:1 substitute. It absorbs too much moisture and will dry out the cookie.

What brand of keto marshmallows do you recommend?

Max Mallow, Know Brainer, or homemade gelatin-based marshmallows. Always check net carbs on the label.

Do I need a cast iron skillet?

Nope! Any oven-safe 9-inch pan works. A pie dish or croquette dish can also be used

Can I make this ahead of time?

Yes! Bake ahead and reheat in the oven at 300°F for 10 minutes before serving.

Is this dessert kid-friendly?

Absolutely. Most kids won’t even notice it’s keto!
