Chocolate Hazelnut Crunch Cookies
I grew up with a jar of store-bought chocolate-hazelnut spread and a soft spot for crunchy cookies; this recipe sits right between those memories and a warm, just-baked reality. These Chocolate Hazelnut Crunch Cookies combine cocoa-rich dough, toasted hazelnut bite, and pockets of melty chocolate—great for afternoon coffee breaks, lunchbox treats, or simple holiday cookie trays.
Why you’ll love this dish
These cookies are an easy way to get big chocolate flavor without complicated technique. They’re quick to mix, use pantry basics, and the toasted hazelnuts give a satisfying crunch that elevates an otherwise classic chocolate cookie. Make them when you want something comforting but a little grown-up—think potlucks, cookie swaps, or a weekend baking session with kids.

The cooking process explained
Before you gather ingredients: these cookies are basically creamed butter and sugar, enriched with one egg and vanilla, then combined with a cocoa-flour mixture and finished with hazelnuts and chocolate chips. Expect a short mixing time (no chilling required) and a quick 10–12 minute bake. The goal is a set edge with a slightly soft center that firms as it cools.
What you’ll need
- 1 cup hazelnuts, chopped (toast for better flavor — see tips)
- 1 cup all-purpose flour
- 1/2 cup cocoa powder (unsweetened)
- 1/2 cup butter, softened
- 1 cup sugar
- 1 egg
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup chocolate chips
Notes and substitutions: swap half the chocolate chips for chopped dark chocolate for deeper flavor; use avocado oil-based butter substitute for dairy-free results (texture will vary). If you like a crisper cookie, increase sugar to 1 1/4 cups or bake a minute longer.
Step-by-step overview
- Toast and chop hazelnuts (optional but recommended).
- Cream butter and sugar, then add egg and vanilla.
- Whisk dry ingredients, fold into wet mixture until just combined.
- Stir in hazelnuts and chocolate chips.
- Drop dough on a lined baking sheet and bake 10–12 minutes.
- Cool briefly on the sheet, then transfer to a rack to finish setting.
Directions to follow
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment.
- If toasting hazelnuts: spread them on a pan and roast 8–10 minutes at 350°F until fragrant. Rub in a towel to remove skins, then chop roughly.
- In a large bowl, cream the softened butter and sugar with a hand mixer or stand mixer until light and slightly fluffy, about 2–3 minutes.
- Beat in the egg and vanilla until smooth and combined.
- In a separate bowl, whisk together flour, cocoa powder, baking soda, and salt.
- Gradually add the dry mix to the wet ingredients, stirring with a spatula until just incorporated—avoid overmixing.
- Fold in the chopped hazelnuts and chocolate chips evenly through the dough.
- Use a spoon or small cookie scoop to drop rounded tablespoons of dough onto the prepared sheet, spacing about 2 inches apart.
- Bake for 10–12 minutes, watching for set edges; centers should still be slightly soft.
- Let cookies cool on the baking sheet for 3–4 minutes, then transfer to a wire rack to cool completely.
Best ways to enjoy it
Serve warm with a glass of milk, espresso, or a scoop of vanilla ice cream for a dessert mash-up. For a party tray, dust lightly with cocoa or drizzle melted chocolate on top for a finished look. These cookies also pair nicely with nutty spreads — try them alongside a plate of meringues or lighter cookies like these chocolate-dipped meringue cookies for contrast.
How to store & freeze
Store cooled cookies in an airtight container at room temperature for up to 5 days. Layer with parchment to prevent sticking. To freeze: place cookies in a single layer on a baking sheet until firm, then transfer to a freezer-safe bag or container for up to 3 months. Thaw at room temperature for 30–60 minutes. If reheating, warm a cookie in a 300°F oven for 5–7 minutes or 10 seconds in a microwave for a just-melted center. Always let warm items cool enough to handle safely.
Helpful cooking tips
- Toast the hazelnuts for deeper flavor: 350°F for 8–10 minutes, cool, then chop.
- Room-temperature butter creams better and traps air for lighter cookies—don’t melt it.
- Use Dutch-processed cocoa for a smoother, less acidic chocolate note; natural cocoa gives a brighter chocolate tang.
- If dough seems too wet, add a tablespoon of flour at a time; if too dry, a teaspoon of milk loosens it.
- For uniform cookies, use a 1-tablespoon scoop and flatten slightly before baking.

Flavor swaps
- Nut-free: replace hazelnuts with toasted rolled oats or crushed pretzels for crunch.
- Double chocolate: replace half the flour with an extra 1/4 cup cocoa for a fudgier cookie.
- Salted caramel: press a soft caramel candy into the center of each cookie after 6 minutes of baking, then finish baking.
- Vegan: use vegan butter and a flax egg (1 tbsp ground flax + 2.5 tbsp water, chilled) — texture will be slightly denser.
Helpful answers
Q: How long does it take to prep and bake these?
A: Active prep is about 15 minutes (toasting hazelnuts adds time), and bake time is 10–12 minutes—plan for ~30 minutes total.
Q: Can I make the dough ahead?
A: Yes. Refrigerate the dough for up to 24 hours (cover tightly) or freeze scooped dough balls for up to 3 months. Bake from frozen, adding 1–2 minutes to the bake time.
Q: Do I need to toast the hazelnuts?
A: You don’t have to, but toasting concentrates oils and flavors and makes the cookies taste noticeably richer.
Q: Can I substitute other nuts?
A: Absolutely—walnuts or pecans work well. Note texture and oil content vary, so chop to similar sizes for even distribution.
Q: What causes flat cookies and how to fix them?
A: Flat cookies usually stem from over-softened or melted butter, too much sugar, or too-warm dough. Chill the dough 15–20 minutes if your butter got too soft, and measure ingredients accurately.
