Keto Hazelnut Chocolate Muffins - Rich, Nutty, and Low-Carb
Ingredients
- Blanched almond flour (fine grind)
- Hazelnut flour or finely ground roasted hazelnuts
- Unsweetened cocoa powder (Dutch-process or natural)
- Erythritol, allulose, or a monk fruit blend (granulated)
- Baking powder (aluminum-free)
- Fine sea salt
- Instant espresso powder (optional, enhances chocolate)
- Eggs (room temperature)
- Greek yogurt or full-fat sour cream
- Unsalted butter (melted and cooled) or refined coconut oil
- Vanilla extract
- Hazelnut extract (optional but great for aroma)
- Sugar-free dark chocolate chips or chopped sugar-free chocolate
- Chopped roasted hazelnuts (optional, for topping)
- Nonstick spray or silicone muffin liners
Instructions
- Preheat and prep: Heat the oven to 350°F (175°C). Line a 12-cup muffin tin with silicone liners or paper liners lightly sprayed with nonstick spray.
- Mix dry ingredients: In a large bowl, whisk together 1 1/2 cups almond flour, 1/2 cup hazelnut flour, 1/3 cup cocoa powder, 1/2 to 2/3 cup keto sweetener (to taste), 2 teaspoons baking powder, 1/4 teaspoon salt, and 1/2 teaspoon espresso powder.
- Whisk wet ingredients: In a separate bowl, whisk 3 large eggs, 1/2 cup Greek yogurt or sour cream, 1/3 cup melted butter (cooled) or coconut oil, 1 1/2 teaspoons vanilla, and 1/4 teaspoon hazelnut extract if using.
- Combine: Pour the wet ingredients into the dry. Stir with a spatula until just combined. The batter will be thick but scoopable. Fold in 1/2 cup sugar-free chocolate chips.
- Portion: Divide the batter evenly among the 12 cups. If you like, sprinkle a few chopped hazelnuts and extra chips on top for texture.
- Bake: Bake for 18–22 minutes, until the tops are set and a toothpick comes out with just a few moist crumbs. Do not overbake.
- Cool: Let muffins cool in the pan for 10 minutes, then transfer to a rack to finish cooling. Keto muffins firm up as they cool.
- Serve: Enjoy warm or at room temperature. A smear of butter or a dollop of whipped cream makes them feel extra special.
Why This Recipe Works
These muffins use a blend of almond flour and hazelnut meal for a tender, cake-like texture that stays moist. A touch of cocoa powder and espresso powder boosts the chocolate flavor without adding carbs. Erythritol or allulose sweetener keeps them keto-friendly while maintaining a clean taste and good structure.
Greek yogurt or sour cream adds richness and helps the muffins rise nicely with the help of baking powder. Finally, a handful of sugar-free chocolate chips makes them feel extra indulgent.

Storage Instructions
- Room temperature: Store in an airtight container for up to 2 days.
- Refrigerator: Keep up to 5–6 days. Rewarm for 10–15 seconds in the microwave to refresh texture.
- Freezer: Freeze for up to 2 months. Wrap individually and store in a freezer bag.
Thaw overnight in the fridge or at room temperature for 1 hour.
Health Benefits
- Low in carbs: Almond and hazelnut flours provide structure without spiking blood sugar.
- Healthy fats: Nuts and butter deliver satiating fats that help curb cravings.
- Gluten-free: Naturally free of wheat, so it’s friendly for gluten-sensitive eaters.
- Protein boost: Eggs and Greek yogurt contribute to a more balanced, filling snack.
- Reduced sugar: Using erythritol or allulose keeps sweetness high and carbs low.
What Not to Do
- Don’t pack the flour: Scoop almond and hazelnut flours lightly and level with a knife to avoid dense muffins.
- Don’t overmix: Stir until just combined. Overworking the batter deflates the rise.
- Don’t skip cooling: Warm keto muffins can seem soft; they set as they cool. Cutting too soon can make them crumble.
- Don’t overbake: Dryness happens fast with nut flours.
Check early and pull when crumbs are moist.
- Don’t use baking soda alone: This recipe relies on baking powder for lift and balanced flavor.
Alternatives
- Dairy-free: Swap butter for refined coconut oil and use a thick dairy-free yogurt (like coconut). Check that chocolate chips are dairy-free.
- No hazelnut flour: Use all almond flour and add 1/4 teaspoon extra hazelnut extract for flavor.
- Sweetener swaps: Allulose gives a softer crumb; erythritol gives more structure. A blend often works best.
Avoid liquid sweeteners as they can make the batter too loose.
- Add-ins: Stir in 1/4 cup chopped roasted hazelnuts for crunch or a tablespoon of cocoa nibs for extra chocolate bite.
- Frosted treat: Top with a quick keto ganache (sugar-free chocolate + a splash of cream or coconut cream) once cooled.
Can I make these muffins nut-free?
It’s tough, since the structure relies on nut flours. You can try superfine sunflower seed flour as a 1:1 swap for almond and hazelnut flours, but note that it may react with baking soda or powder and cause a green tint. The taste will still be good.
Which sweetener tastes best in chocolate muffins?
Allulose has the cleanest taste and a very tender crumb, while erythritol or monk fruit blends hold structure better.
If you’re sensitive to erythritol cooling, try a half-and-half mix with allulose for balance.
How do I keep them from sticking to liners?
Use silicone liners or parchment-style paper liners, and lightly spray them. Let muffins cool 10 minutes before removing. This reduces sticking and crumbling.
Can I make them larger or mini?
Yes.
For jumbo muffins, fill 6 cups and bake 22–26 minutes. For mini muffins, fill 24–30 wells and bake 10–12 minutes. Always check with a toothpick near the center.
Do I need the espresso powder?
No, but it deepens the chocolate flavor without making the muffins taste like coffee.
If you don’t have it, just leave it out.
How many carbs per muffin?
Exact macros vary by brand, but a typical muffin lands around 3–5g net carbs when using almond and hazelnut flours, a keto-friendly sweetener, and sugar-free chips. Check your ingredients and calculate for accuracy.
Final Thoughts
These keto hazelnut chocolate muffins are simple, satisfying, and full of rich flavor without the sugar. They’re easy enough for a weekday bake but special enough for a weekend brunch.
With a few smart swaps and a short ingredient list, you’ll have a reliable low-carb treat ready anytime cravings strike. Keep a batch in the freezer, and you’ll always have something sweet, cozy, and keto-friendly on hand.
