You’re going to want a couple dozen of these Chocolate Chunk Hazelnut Cookies! They’re so soft but chewy, loaded with dark chocolate, and are gluten-free!
If you’re a fan of hazelnut chocolates then you’re going to be a huge fan of these chocolate chunk hazelnut cookies. Made with hazelnut flour and topped with huge chunks of dark chocolate, you’re going to want to make these weekly!
We are obsessed with these cookies here. They remind me of Ferrero Rocher and they’re the perfect little holiday treat! They’re like next level chocolate chip cookies. I love to whip up a batch whenever we have guests on the way because not only does the house smell amazing, these cookies are dairy-free, gluten-free, and paleo friendly so they accommodate a lot of dietary preferences.

We use hazelnut flour for this cookie as a way to change up our usual routine with baking with almond flour. Here on Primevera Kitchen, I bake with many different types of flours so if you’re all out of hazelnut flour, try making my Gluten Free Chocolate Chunk Cookies, Chocolate Almond Butter Cookies, or Coconut Flour Chocolate Chip Cookies.
Hazelnut flour has more texture than almond flour and it gives these chocolate chunk hazelnut cookies a rich, nutty flavour throughout the cookie. On top of that, the big chocolate chunks throughout hazelnut cookies makes them soft in the center. You’ll want to use a quality chocolate for this as they are definitely the star of the show here.

How to Make Hazelnut Flour
If you cannot find hazelnut flour at your local grocery store, not to worry. You can make your own at home! Simply add 2 cups of raw hazelnuts (they can be found in the baking aisle at most grocery stores) to a food processor and blend until it is a fine powder.
Depending on your food processor, you might have to add more hazelnuts to make sure the blade is covered. Be sure to not over blend the hazelnuts. You can use a fine mesh strainer to remove any larger chunks that didn’t get grind up.
If you want to make a batch so you have hazelnut flour on hand regularly, store the flour in the fridge in an airtight container and it’ll last for several months!
Make Ahead and Freezer Tips
- You can make these chocolate chunk hazelnut cookies ahead of time if you would like.
- These cookies last up to 5 days when stored in an airtight container at room temperature.
- You can also wrap them tightly in plastic wrap and transfer the chocolate chunk hazelnut cookies to a freezer safe container and freeze them for later as well.
- When ready, thaw the cookies overnight in the fridge before bringing them to room temperature and serving.
- Cookies can be frozen for up to 3 months.
Substitutions and Tips
- If you don’t have dark chocolates on hand, you can substitute with other types of chocolates such as white chocolate, milk chocolate, caramel, and more! We like to use Lily’s 70% cacao chocolates for these cookies but we also love Ghirardelli as well.
- To add more hazelnut flavours, you can fold in some roasted hazelnuts as well to the dough to get that extra crunch.
- To get the perfect topped cookie, before baking, use the reserved chocolate chunks and place one or two on the top of the cookie. So when it bakes, the chocolate chunks remain visible.
- There’s no need to use a mixer for these chocolate chunk hazelnut cookies but if you do, make sure your chocolates are folded in by hand so the batter doesn’t get over mixed.

EmPea says
Just making these.. ingredients says maple syrup method says honey. I presume there isn’t much difference other than taste, presume also typo in recipe entry. Or should it be maple syrup/honey? Could also have different flavour with honey based on the specific honey you buy (e.g. Many places where I live have different types like apple blossom, yellow box, leatherwood, etc…), these have varying flavour.
Got 21 biscuits using tablespoon size, reckon if I use dessert spoon can spread further out and get more than 30. But will need to alter cooking time.
Awaiting the taste test, was looking for recipe to use a stack of hazelnut meal I had.
And it was……..good (I ate it warm for the nice hot melts choc texture. Should be ok cold too.
Thanks
Olivia says
I can use honey or maple. Both works just fine. I just adjusted the recipe to clear further confusion. Thanks for pointing it out!
