These indulgent Chocolate Hazelnut Crunch Cookies combine the rich flavors of toasted hazelnuts and cocoa in a buttery cookie base. The dough is studded with chopped hazelnuts for texture, then baked to perfection. Once cooled, each cookie is dipped in melted chocolate and topped with additional hazelnuts for extra crunch. The combination of chocolate and hazelnut creates a flavor reminiscent of popular European chocolate-hazelnut spreads, making these cookies perfect for special occasions or as an elevated everyday treat.

Step-by-Step Instructions

Toast the Hazelnuts:
Spread hazelnuts evenly on a baking sheet and bake at three hundred fifty degrees Fahrenheit for around ten to twelve minutes Stir halfway through to prevent burning After cooling rub the hazelnuts gently in a towel to loosen skins then roughly chop For topping set aside half a cup of the chopped nuts which gives the cookies their finishing crunch
Make the Cookie Dough:
In a medium bowl whisk together flour cocoa powder baking powder and salt to create an even mixture In a separate large bowl use a mixer to cream the butter granulated sugar and brown sugar until light in color and fluffy about two to three minutes Beat in the egg and vanilla extract until mixture is smooth Gradually add the flour mixture stirring just until you see no more flour Fold in the remaining chopped toasted hazelnuts so every cookie gets some pieces
Shape and Bake the Cookies:
Line your baking sheet with parchment paper for easy removal Scoop out tablespoon sized mounds of dough Roll between your hands into even balls and then gently press each ball down to form a thick disc Place each at least two inches apart Bake in the preheated oven for ten to twelve minutes Edges should be set but centers still look soft Let cookies cool completely on a wire rack which ensures they stay crisp yet tender
Coat the Cookies:
In a microwave safe bowl melt chopped chocolate and optional coconut oil Stir every thirty seconds until fully smooth Dip the top of each cooled cookie into the chocolate so it is nicely coated Lay dipped cookies flat on parchment or a wire rack Immediately sprinkle with reserved chopped hazelnuts so they adhere Let chocolate set at room temperature or chill in the fridge if you are impatient

Hazelnuts are my weakness and make every bite memorable Once I let my daughter drizzle the chocolate herself and she declared it the best baking day ever so now it has become our rainy Sunday ritual

Storage Tips

Store cooled cookies in an airtight container at room temperature for up to five days For longer storage freeze uncoated cookies then dip in chocolate after thawing just before serving This keeps the coating shiny and fresh

Ingredient Substitutions

If you need a nut free option sunflower seeds provide crunch though the flavor will differ Swap coconut oil with the same amount of neutral vegetable shortening or leave out for a firmer shell For a deeper chocolate note use dark chocolate instead of semi sweet

Serving Suggestions

Stack these cookies high on a dessert tray beside coffee or tea Their rich taste pairs beautifully with a scoop of vanilla ice cream As a special treat try sandwiching two cookies together with a layer of Nutella or your favorite chocolate spread

Frequently Asked Questions

→ Can I use pre-chopped hazelnuts for this recipe?

Yes, you can use pre-chopped hazelnuts, but toasting them yourself will significantly enhance the flavor. If using pre-chopped nuts, reduce the toasting time to 5-7 minutes to prevent burning, watching carefully as smaller pieces toast faster.

→ How do I properly store these cookies?

Store the cookies in an airtight container at room temperature for up to 5 days. For longer storage, place them in the refrigerator for up to 2 weeks. You can also freeze them (before adding the chocolate coating) for up to 3 months.

→ Can I substitute the hazelnuts with other nuts?

Absolutely! While hazelnuts pair beautifully with chocolate, you can substitute them with almonds, walnuts, or pecans for different flavor profiles. Just make sure to toast them before adding to the dough for the best flavor.

→ Why add coconut oil to the chocolate coating?

Coconut oil or shortening helps thin the chocolate, creating a smoother coating that's easier to work with. It also helps the chocolate set with a nice shine and prevents it from becoming too brittle when hardened.

→ How can I tell when the cookies are perfectly baked?

The cookies are done when the edges are set but the centers still look slightly soft. They will continue to firm up as they cool. Overbaking will result in dry cookies, so it's better to slightly underbake than overbake.

→ Can I make the dough ahead of time?

Yes, you can make the dough up to 3 days in advance and store it covered in the refrigerator. You can also form the dough balls and freeze them for up to 3 months. Bake directly from frozen, adding 1-2 minutes to the baking time.

Instructions

Step 01

Preheat oven to 175°C. Spread hazelnuts on a baking sheet and toast for 10-12 minutes, stirring halfway through. Allow to cool, then roughly chop. Reserve 60g of chopped hazelnuts for the topping.

Step 02

In a medium bowl, whisk together flour, cocoa powder, baking powder, and salt. In a large bowl, cream butter with granulated and brown sugars until light and fluffy (2-3 minutes). Add egg and vanilla extract, mixing until smooth. Gradually incorporate the dry ingredients, then fold in the toasted hazelnuts.

Line a baking sheet with parchment paper. Scoop tablespoon-sized portions of dough, roll into balls, then gently flatten into discs. Bake in the preheated oven for 10-12 minutes, until edges are set. Cool completely on a wire rack.

Step 04
