Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Light brown sugar provides both sweetness and depth of flavor with its molasses notes that complement the chocolate perfectly. Its moisture also helps bind these cookies together.

Butter creates richness and helps the cookies achieve the perfect fudgy texture. It also aids in binding all the ingredients together as it cools.

Whole milk adds creaminess and helps dissolve the sugar. You can substitute with 2% milk, but whole milk gives the best consistency.

Unsweetened cocoa powder delivers that deep chocolate flavor without additional sweetness. Use Dutch-processed for a smoother taste or regular cocoa powder for a more intense chocolate flavor.

Old-fashioned oats form the backbone of these cookies, providing hearty texture and substance. Don’t substitute with quick oats as they’ll make the cookies mushy, and steel-cut oats would be too crunchy.

Sweetened flaked coconut adds a wonderful texture and subtle tropical flavor that complements the chocolate beautifully. The coconut also helps bind the cookies together as they set.

Creamy peanut butter brings a nutty dimension and helps the cookies hold their shape. You can use natural peanut butter, but the cookies may be slightly less firm.

Chocolate-hazelnut spread intensifies the chocolate flavor while adding a beautiful nuttiness. This ingredient makes these cookies extra special and irresistible.

Vanilla extract balances and enhances all the other flavors in the cookie. Pure vanilla extract works best for the cleanest flavor.

Salt is crucial for balancing sweetness and bringing out the chocolate flavor. Even in sweet recipes, salt plays a vital role in developing complex flavors.

Directions

Line two rimmed baking sheets with parchment or wax paper and set aside.
In a medium saucepan, bring the sugar, butter, milk, and cocoa powder to a rolling boil over medium-high heat. Let it boil for 1 to 2 minutes, stirring often, until the mixture reaches 230°F on an instant-read thermometer. Remove from heat.
Stir in oats, coconut, peanut butter, chocolate-hazelnut spread, vanilla, and salt until well combined.
Working quickly, drop tablespoons of the mixture onto the prepared pans, flattening slightly. Sprinkle with more coconut and press gently to stick. Let stand at room temperature for about 30 minutes, or until firm.
Store in an airtight container in a cool, dry place for up to 1 week.

Variations

Nutty Delight: Add 1/2 cup of chopped walnuts or pecans to the mixture for added crunch and nutty flavor.

Chocolate Chip Boost: Fold in 1/2 cup of mini chocolate chips after the mixture has cooled slightly for pockets of melty chocolate.

Almond Joy: Replace the peanut butter with almond butter and add 1/2 teaspoon of almond extract for an Almond Joy-inspired cookie.

Spiced Version: Add 1/2 teaspoon of cinnamon and a pinch of cayenne for a Mexican chocolate twist.

Healthier Option: Reduce sugar to 1 1/2 cups and use unsweetened coconut to lower the overall sweetness.

Vegan Adaptation: Use coconut oil instead of butter, plant-based milk, and ensure your chocolate-hazelnut spread is vegan-friendly.

Gluten-Free: Make sure to use certified gluten-free oats if serving to someone with celiac disease or gluten sensitivity.

Storage/Reheating

Counter Storage: Store cookies in an airtight container at room temperature for up to 1 week. Place parchment paper between layers to prevent sticking.

Refrigerator: For a firmer texture and longer shelf life, store in the refrigerator for up to 2 weeks. Allow to come to room temperature before serving for the best flavor and texture.

Freezer: These cookies freeze beautifully. Place them in a single layer on a baking sheet until frozen, then transfer to a freezer bag or container with parchment paper between layers. They’ll keep for up to 3 months. Thaw at room temperature for about 30 minutes before enjoying.

Reheating: These cookies are designed to be enjoyed at room temperature, but if you’d like them slightly warm, microwave for 5-10 seconds. Be careful not to overheat, as they will melt.

FAQs

Why didn’t my cookies set properly?

The most common reason cookies don’t set properly is that the boiling mixture didn’t reach the right temperature. Use a candy thermometer to ensure it reaches 230°F. If you don’t have a thermometer, make sure to boil for the full 1-2 minutes to evaporate enough moisture.

Can I use quick oats instead of old-fashioned oats?

While quick oats will work in a pinch, they absorb more moisture and create a denser cookie. Old-fashioned oats provide the best texture. If using quick oats, reduce the amount by about 1/4 cup.

How can I make these cookies less sweet?

Reduce the brown sugar to 1 1/2 cups and use unsweetened coconut. You could also use natural peanut butter with no added sugar and a darker chocolate-hazelnut spread if available.

Can I make these cookies without peanut butter due to allergies?

Absolutely! You can replace the peanut butter with sunflower seed butter, almond butter, or even tahini for a peanut-free version. You could also simply double the chocolate-hazelnut spread, though the cookies may be slightly softer.

What if I don’t have chocolate-hazelnut spread?

You can substitute with additional peanut butter and add 2 tablespoons of cocoa powder and 2 tablespoons of sugar to maintain the sweetness and chocolate flavor.

My mixture hardened before I could form all the cookies. What happened?

The mixture does set up quickly as it cools. If this happens, return the saucepan to low heat for a few seconds, stirring constantly, until it’s just pliable enough to work with again.

Can I make these cookies smaller to get more servings?

Yes! Use a teaspoon instead of a tablespoon to drop smaller portions, which will yield approximately 50-60 cookies. Just watch them closely as smaller cookies will set faster.

Are these cookies gluten-free?

If you use certified gluten-free oats, these cookies can be gluten-free. However, always check the labels on your other ingredients, particularly the chocolate-hazelnut spread, as some brands may contain gluten.

How do I know when the cookies are fully set?

The cookies should be firm to the touch and not stick to your finger when gently pressed. If your kitchen is warm or humid, it may take longer than 30 minutes for them to set completely.

Can I make this recipe dairy-free?

Yes, substitute the butter with coconut oil or a plant-based butter alternative and use almond milk or another non-dairy milk in place of whole milk. Ensure your chocolate-hazelnut spread is dairy-free as well.
