Their elegant appearance and rich taste make them perfect for special occasions, while their simple preparation makes them approachable for everyday baking. You can even customize the ganache by using different types of chocolate or adding flavorings like espresso or orange zest.

These cookies also make a thoughtful gift. Package them in a decorative box or tin, and you have a delightful homemade present for friends and family. Imagine their surprise and joy as they open up a gift of hand-baked cookies, showcasing not only your baking skills but also your care and thoughtfulness.

Storage and Shelf Life

Once baked and filled with ganache, these cookies can be stored in an airtight container at room temperature for up to a week. However, they are best enjoyed fresh, as the ganache can soften over time. If you need to prepare them in advance, consider baking the cookies and filling them with ganache closer to serving time to maintain their delightful textures.

For longer storage, you can freeze the unfilled cookies. Simply bake and cool them, then place them in a freezer-safe container. When you're ready to enjoy them, thaw the cookies and fill them with freshly made ganache. This way, you can always have a batch of delicious Hazelnut Thumbprint Cookies ready to go!

Ingredients

For the Cookies

  • 1 cup hazelnuts, toasted and finely ground
  • 1 cup all-purpose flour
  • 1/2 cup unsalted butter, softened
  • 1/2 cup granulated sugar
  • 1 large egg yolk
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt

For the Ganache

  • 1/2 cup heavy cream
  • 4 ounces dark chocolate, chopped
  • 1 tablespoon unsalted butter

Make sure to have all the ingredients measured and prepared before starting the recipe.

Instructions

Prepare the Cookie Dough

In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the egg yolk, vanilla extract, and salt, mixing until well combined. Gradually stir in the ground hazelnuts and flour until a dough forms.

Shape the Cookies

Preheat your oven to 350°F (175°C). Roll the dough into 1-inch balls and place them on a lined baking sheet. Use your thumb or the back of a spoon to create an indentation in the center of each cookie.

Bake the Cookies

Bake in the preheated oven for 15-20 minutes, or until the edges are lightly golden. Remove from the oven and let them cool completely on a wire rack.

Make the Ganache

While the cookies are cooling, heat the heavy cream in a small saucepan until just simmering. Pour over the chopped dark chocolate and let it sit for a minute before stirring until smooth. Add the butter and mix until fully incorporated.

Fill the Cookies

Once the cookies are completely cooled, fill each indentation with the silky ganache. Allow the ganache to set before serving.

Tips for Perfect Cookies

To ensure the best texture and flavor, toast your hazelnuts before grinding them. This simple step enhances their nuttiness and adds depth to the cookie. If you're short on time, you can buy pre-ground hazelnuts, but freshly ground will always yield better results.

When shaping your cookies, make sure to create a deep enough indentation for the ganache without breaking the cookie. A well-defined thumbprint allows for more ganache, maximizing the chocolate experience in every bite.

Serving Suggestions

These cookies pair wonderfully with various beverages. A rich cup of coffee or a glass of cold milk complements the nutty flavors beautifully, enhancing the overall tasting experience. You can also serve them alongside a dessert wine for a more sophisticated pairing.

For a festive touch, consider garnishing the ganache with a sprinkle of sea salt or crushed hazelnuts. This not only adds visual appeal but also introduces an extra layer of flavor that your guests will love.
