Ingredients
Method
- Prep the pan. Line a rimmed baking sheet or a 9x13-inch pan with parchment paper. Leave overhang on the sides for easy lifting.
- Toast the hazelnuts. Place hazelnuts on a dry skillet over medium heat. Stir often for 5–7 minutes until fragrant and lightly browned. Remove from heat.
- Remove skins (if needed). If your hazelnuts still have skins, rub them in a clean kitchen towel to shed most of the papery skins. Don’t worry if some remain.
- Chop the nuts. Roughly chop the toasted hazelnuts so you get a mix of bigger chunks and smaller bits. Set aside.
- Melt the chocolate. Place the chocolate and coconut oil (or cocoa butter) in a heatproof bowl. Melt using a double boiler over gently simmering water, stirring until smooth. Or microwave in 20–30 second bursts, stirring between each, until glossy.
- Sweeten to taste. If your chocolate isn’t sweet enough, whisk in powdered allulose or erythritol. Start with 1 tbsp, taste, and add more if needed. Make sure it fully dissolves to avoid grittiness.
- Add flavor. Stir in vanilla (or almond) extract and 1/2 tsp flaky sea salt. If using espresso powder or orange zest, add it now.
- Combine with nuts. Fold in about 3/4 of the chopped hazelnuts, reserving a handful for topping. Mix so the nuts are evenly distributed.
- Spread the bark. Pour the mixture onto the prepared pan. Use an offset spatula to spread it into an even layer, about 1/4-inch thick. Sprinkle the remaining hazelnuts on top. Finish with a light pinch of flaky sea salt.
- Set and chill. Refrigerate for 20–30 minutes, or until firm. For best snap, let it set at cool room temperature first, then finish in the fridge.
- Break into pieces. Lift the bark using the parchment and break into uneven shards. Aim for palm-sized pieces for easy portioning.
- Serve and store. Keep a few pieces at room temperature for snacking and store the rest as directed below.

What Makes This Special
This bark focuses on pure flavor and smart swaps. The chocolate is sweetened with a keto-friendly sweetener, so you get real chocolate taste without the sugar spike.
Toasted hazelnuts add a bold, nutty crunch that pairs perfectly with dark chocolate. A hint of vanilla and sea salt rounds everything out and makes each bite feel balanced. It’s a low-effort recipe with high payoff—both in taste and texture.
Ingredients
- 10 oz (285 g) sugar-free dark chocolate (70–85% cacao, sweetened with erythritol, allulose, or stevia)
- 1 cup (135 g) hazelnuts, skinned and roughly chopped
- 2 tbsp powdered allulose or erythritol (optional, to taste, if your chocolate isn’t sweet enough)
- 1 tsp vanilla extract (or 1/2 tsp almond extract for a stronger nutty note)
- 1–2 tbsp coconut oil or cocoa butter (optional, for extra gloss and snap)
- 1/2 tsp flaky sea salt, plus more for finishing
- Optional add-ins: 1 tbsp unsweetened cocoa nibs, 1 tsp espresso powder, 1 tsp orange zest

Storage Instructions
- Room temperature: If your kitchen is cool (below 70°F/21°C), store in an airtight container for up to 1 week.
- Refrigerator: Keeps well for 2–3 weeks in a sealed container. Add parchment between layers to prevent sticking.
- Freezer: Freeze for up to 3 months. Thaw in the fridge for 30 minutes before serving to avoid condensation.
- Avoid heat swings: Rapid temperature changes can cause bloom (a white, streaky appearance).
It’s harmless but less pretty.
Health Benefits
- Low in sugar: Using keto-friendly chocolate keeps net carbs in check while delivering real cocoa flavor.
- Healthy fats: Hazelnuts and cocoa provide monounsaturated fats, which can support heart health and satiety.
- Antioxidants: Dark chocolate is rich in polyphenols that may support healthy inflammation response.
- Minerals: Hazelnuts add magnesium, manganese, and vitamin E for overall wellness.
- Steady energy: The fat and fiber combo can help curb cravings and keep you satisfied between meals.
What Not to Do
- Don’t use standard milk chocolate. It’s typically high in sugar and not keto-friendly.
- Don’t skip toasting the hazelnuts. Raw nuts taste flat. Toasting adds crunch and deep flavor.
- Don’t overheat the chocolate. High heat can scorch it or cause it to seize. Melt low and slow.
- Don’t add liquid sweeteners. Water-based syrups can cause the chocolate to seize.
Use powdered keto sweeteners.
- Don’t store near strong odors. Chocolate absorbs smells. Keep it sealed and away from pungent foods.
Recipe Variations
- Mocha Hazelnut Bark: Add 1–2 tsp espresso powder to the melted chocolate and sprinkle cocoa nibs on top.
- Orange Dark Chocolate Bark: Stir in 1 tsp finely grated orange zest and a tiny pinch of ground cardamom.
- Salted Almond-Hazelnut Mix: Swap half the hazelnuts for toasted sliced almonds and finish with extra flaky salt.
- Peppermint Crunch: Add 1/2 tsp peppermint extract and top with crushed sugar-free peppermint candies.
- Coconut Macadamia: Replace hazelnuts with a mix of toasted macadamias and unsweetened coconut flakes.
- Ultra-Dark: Use 90% cacao chocolate and add a touch more powdered allulose to balance bitterness.
FAQ
Is this truly keto-friendly?
Yes, as long as you use sugar-free dark chocolate and a keto-approved sweetener like allulose or erythritol. Always check the nutrition label for net carbs per serving.
Can I make it dairy-free?
Most dark chocolates used here are already dairy-free, but read labels to be sure.
Use coconut oil or cocoa butter, not butter, and you’re set.
My chocolate seized. Can I fix it?
If it becomes thick and grainy, whisk in 1–2 tsp warm coconut oil or cocoa butter until smooth. If it’s badly seized, start over with clean, dry tools.
How do I get that glossy finish?
Use gentle heat, stir often, and add a small amount of cocoa butter or coconut oil.
Let it set in a cool room before moving it to the fridge to help prevent bloom.
Can I lower the carbs even more?
Use a higher-percentage chocolate (85–90% cacao) and skip additional sweetener. Break the bark into smaller pieces to manage portions.
What if I’m allergic to hazelnuts?
Swap in toasted almonds, pecans, walnuts, or pumpkin seeds. Toasting is key for flavor and crunch, regardless of the nut or seed.
Why powdered sweetener instead of granular?
Powdered sweeteners dissolve more easily and don’t leave a gritty texture.
If you only have granular, blitz it in a blender to powder it before using.
Can I add protein powder?
You can, but add only 1–2 tbsp and whisk well. Too much can make the chocolate chalky and stiff.
How thick should the bark be?
A quarter-inch thickness gives the best snap and chew. Thinner bark is more brittle; thicker bark can be tough to bite through.
What’s a good serving size?
Typically 1–2 small pieces, about 1 ounce total.
Adjust based on your daily carb and calorie goals.
In Conclusion
Keto Toasted Hazelnut Chocolate Bark is a simple treat that feels luxurious. It’s quick to make, easy to customize, and satisfies chocolate cravings without the sugar crash. With toasted nuts, a pinch of salt, and rich dark chocolate, every bite tastes balanced and special.
Keep a batch on hand for a smart dessert or an afternoon pick-me-up that fits your goals.
