Chocolate Hazelnut Thumbprint Cookies

The rich aroma of chocolate and toasted hazelnuts fills my kitchen every time I make these thumbprint cookies, bringing back memories of European cafés and holiday gatherings. After countless batches and subtle tweaks, I've perfected this recipe that combines buttery cocoa dough with the irresistible combination of chocolate and hazelnuts. These cookies have become my signature contribution to family celebrations and cookie exchanges.

Just last week, I brought these to a friend's dinner party, and her young daughter declared them "fancy chocolate cookies!" That's exactly what I love about them - they're special enough for celebrations but simple enough to make any time the craving strikes.

Essential Ingredients Selection

• Butter: Use unsalted, room temperature butter for perfect cookie texture. I've found European-style butter creates an especially rich result
• Cocoa Powder: Choose Dutch-processed cocoa for deeper color and smoother flavor. Natural cocoa works too but gives a different taste
• Hazelnuts: Fresh, whole hazelnuts that you chop yourself provide the best flavor and texture. Look for ones without any bitter skins
• Chocolate Hazelnut Spread: Quality matters here. Choose a spread that's rich and glossy
• Vanilla Extract: Pure vanilla extract enhances both chocolate and nut flavors
• Salt: Fine sea salt balances the sweetness perfectly

Detailed Cooking Instructions

Dough Preparation:

Beat softened butter until creamy and light, about 2 minutes. Add sugar gradually, continuing to beat until fluffy. Mix in egg and vanilla until well combined. Whisk dry ingredients separately before adding. Mix until dough just comes together - don't overwork. Chill dough for 30 minutes for easier handling.

Shaping and Rolling:

Toast hazelnuts until fragrant, about 8-10 minutes. Let nuts cool, then chop finely in food processor. Roll dough into 1-inch balls using clean hands. Roll each ball in chopped hazelnuts until well-coated. Place on lined baking sheets 2 inches apart. Make deep indentation in center of each cookie.

Creating Perfect Thumbprints:

Use the back of a ¼ teaspoon measure for uniform indents. Press firmly but gently to avoid cracking. If dough is too soft, chill shaped cookies for 15 minutes. Re-press indentations immediately after baking. Let cookies cool completely before filling.

Filling and Finishing:

Warm chocolate hazelnut spread slightly for easier piping. Transfer to piping bag or zip-top bag with corner snipped. Fill each indentation carefully, avoiding overflow. Let filling set before storing. Drizzle with melted chocolate if desired.

Storage and Presentation:

Allow filling to set completely. Layer cookies between parchment paper. Store in airtight container at room temperature. Best enjoyed within 5 days.

The first time I made these cookies, I learned that patience really matters. Rushing through any step - especially the chilling time - results in cookies that spread too much or lose their shape.

Temperature Control

Working with room temperature ingredients creates a smoother dough that's easier to handle. I've found that leaving butter out for exactly one hour gives the perfect consistency.

Nut Preparation

Toasting the hazelnuts before chopping releases their oils and deepens their flavor. I discovered this makes a huge difference in the final taste of the cookies.

Filling Techniques

After many batches, I've found that slightly warming the chocolate hazelnut spread makes it easier to pipe and creates a smoother finish.

Making Ahead

The dough balls can be frozen before baking, making it easy to have fresh cookies anytime. Just add a minute or two to the baking time.

This recipe started as a way to use up extra hazelnuts during holiday baking. It's since evolved into one of my most requested cookies, combining the best elements of traditional thumbprints with rich chocolate flavor.

Final Thoughts: These chocolate hazelnut thumbprint cookies represent the perfect balance of homey comfort and elegant sophistication. They're equally at home on a holiday cookie platter or alongside afternoon coffee. The combination of tender chocolate cookie, crunchy nuts, and creamy filling creates an irresistible treat that never fails to bring smiles. Whether you're an experienced baker or just starting out, these cookies offer a rewarding baking experience with delicious results.
