NUTRITION (per 1/8 slice):
Calories: 210 | Fat: 18g | Protein: 5g | Total Carbs: 6g | Net Carbs: 3g | Fiber: 3g
INGREDIENTS — COOKIE BASE:
• 2 cups almond flour
• 1/2 tsp baking soda
• 1/4 tsp salt
• 1/2 cup unsalted butter, softened
• 1/3 cup golden erythritol or brown monk fruit sweetener
• 1 tsp vanilla extract
• 1 large egg
INGREDIENTS — MIX-INS & TOPPING:
• 1/3 cup sugar-free chocolate chunks (Lily's or ChocZero)
• 1/3 cup keto marshmallows (Max Mallow or homemade), halved or quartered
• Optional: crushed nuts or unsweetened shredded coconut for garnish
INSTRUCTIONS:
1. Preheat and prep: Preheat 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, whisk almond flour, baking soda, and salt. In another bowl, beat butter and sweetener until fluffy. Add egg and vanilla; mix well. Gradually mix dry into wet until soft dough forms.
3. Add chocolate and marshmallows: Gently fold in most chocolate chips and marshmallows, reserving a few for topping.
4. Press and bake: Press dough evenly into skillet. Dot top with remaining chocolate and marshmallows. Bake 18-22 minutes until golden at edges and just set in middle. Don't overbake—gooey is the goal!
5. Cool slightly & serve: Let cool 5-10 minutes. Serve warm straight from the pan with a spoon or cut into wedges like a pie.
PRO TIPS:
- Use golden sweetener for that brown sugar s'mores flavor.
- Skillet size matters: smaller pan = reduce bake time slightly.
- Don't overmix—just combine until dough comes together for tender results.
- Top with keto ice cream for the ultimate indulgent treat.
VARIATIONS:
- Nut-free: Swap almond flour for sunflower seed flour (1:1 ratio).
- Dairy-free: Use coconut oil or plant-based butter.
- Flavor twist: Add cinnamon for graham cracker vibe or swirl in peanut butter.
- Mini version: Use ramekins for individual cookies—bake 12-15 minutes.
STORAGE:
- Fridge: Covered in skillet or airtight container, up to 5 days.
- Freezer: Slice and freeze in sealed bag, up to 2 months. Reheat in microwave or oven.
- Reheat: Warm at 300°F for 10 minutes before serving for fresh-baked texture.

🧾 Ingredients
For the Cookie Base
2 cups almond flour
1/2 tsp baking soda
1/4 tsp salt
1/2 cup unsalted butter, softened
1/3 cup golden erythritol or brown monk fruit sweetener
1 tsp vanilla extract
1 large egg
Mix-Ins & Topping
1/3 cup sugar-free chocolate chunks (Lily's or ChocZero)
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. Cast iron gives the best crust, but any oven-safe dish works.
2
Make the dough. In a medium bowl, whisk almond flour, baking soda, and salt until well combined. In another large bowl, beat the softened butter and golden sweetener until airy and fluffy—this step is key for tender cookies. Add the egg and vanilla extract, mixing well. Gradually mix the dry ingredients into the wet until a soft, cohesive dough forms. Don't overmix—just combine until it comes together.
3
Add chocolate and marshmallows. Gently fold in most of the sugar-free chocolate chips and keto marshmallows, saving a few for topping. Folding (not stirring vigorously) keeps the marshmallows intact so they melt into gooey pockets instead of disappearing into the dough.
4
Press and bake. Press the dough evenly into the prepared skillet, using wet fingers or a spatula to smooth the top. Dot with the reserved chocolate and marshmallows. Bake for 18–22 minutes, or until golden around the edges and just set in the middle. The center should still look slightly soft—that's perfect. Don't overbake; this cookie is best gooey!
5
Cool slightly & serve. Let cool for 5–10 minutes before diving in. Serve warm straight from the skillet with a spoon for that melty, campfire vibe, or cut into wedges like a pie. Top with a scoop of keto ice cream if you're feeling extra indulgent.
💡 Pro Tip: Use golden erythritol or brown monk fruit sweetener—it mimics the rich, caramel-like flavor of traditional graham crackers. White sweeteners work, but you'll miss that authentic s'mores depth.
❓ Questions I Get (Usually With Chocolate on My Face)
"Can I use coconut flour instead of almond flour?"
No, coconut flour isn't a good 1:1 substitute here. It absorbs way more moisture and will dry out the cookie, giving you a dense, crumbly result. Stick with almond flour for that tender, buttery texture.
"What brand of keto marshmallows do you recommend?"
Max Mallow and Know Brainer are great store-bought options. Or make your own with gelatin, erythritol, and vanilla for total control. Always check the net carbs on the label—some "sugar-free" brands still pack hidden carbs.
"Do I need a cast iron skillet?"
Nope! Any oven-safe 9-inch pan works—a pie dish, ceramic baker, or even individual ramekins. Just adjust bake time slightly if using smaller vessels (ramekins need about 12-15 minutes).
"Can I make this ahead of time?"
Yes! Bake ahead, let cool completely, then cover and store at room temperature for 1 day or fridge for up to 5 days. Reheat in a 300°F oven for 10 minutes before serving to refresh that warm, gooey texture.
"Is this dessert kid-friendly?"
Absolutely! Most kids won't even notice it's keto. The chocolate-marshmallow combo is universally loved, and the almond flour base tastes just like a classic cookie. Just keep an eye on portions if they're new to sugar alcohols.
The Secret to Perfect Gooey Texture
Here's what most people skip: pulling it out early. I know it feels wrong to remove a cookie that still looks soft in the center, but that's exactly when it's perfect. The residual heat finishes the cooking as it cools, giving you that ideal balance of set edges and melty middle.
Also, don't skip the golden sweetener. White erythritol works, but the golden version has that subtle molasses note that mimics brown sugar—the backbone of classic s'mores flavor. It's a small swap that makes a huge difference in authenticity.
⚠️ Most Important Step: Don't overmix the dough. Once the dry ingredients are incorporated, stop. Overmixing develops the almond flour's proteins and leads to a tough, dense cookie. Mix just until no flour streaks remain, then fold in your mix-ins gently.
