  • 1/3 cup (70g) granulated sugar
  • 1/4 cup (35g) powdered sugar
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt

For the Silky Ganache:

  • 4 oz (115g) high-quality dark chocolate, chopped
  • 1/4 cup (60ml) heavy cream
  • 1 teaspoon unsalted butter (optional, for shine)
  • Pinch of salt

Step-by-Step Instructions

Step 1: Prepare the Cookie Dough

  1. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a bowl, cream together butter, granulated sugar, and powdered sugar until light and fluffy.
  3. Mix in vanilla extract.
  4. In a separate bowl, whisk together flour, ground hazelnuts, and salt.
  5. Gradually combine dry ingredients into the butter mixture until a soft dough forms.

Step 2: Shape the Cookies

  1. Roll the dough into 1-inch balls and place on the prepared baking sheet.
  2. Use your thumb or the back of a small spoon to gently press an indentation into the center of each cookie.

Step 3: Bake the Cookies

  1. Bake for 12–15 minutes, until edges are lightly golden.
  2. Remove from oven and allow cookies to cool completely on the baking sheet.

Step 4: Prepare the Ganache

  1. Place chopped chocolate in a heatproof bowl.
  2. In a small saucepan, heat heavy cream until it just begins to simmer.
  3. Pour hot cream over the chocolate and let sit for 2–3 minutes.
  4. Stir until smooth, then add butter and a pinch of salt for extra shine.

Step 5: Fill the Cookies

  1. Spoon or pipe the ganache into the cooled cookie indentations.
  2. Let ganache set at room temperature or in the fridge until firm.

Step 6: Serve and Store

  1. Arrange cookies on a platter or store in an airtight container.
  2. They stay fresh for up to a week and are perfect for gifting in decorative tins.

Tips for Perfect Hazelnut Thumbprint Cookies

  1. Use Fresh Nuts: Roasted, freshly ground hazelnuts add the best flavor.
  2. Keep Dough Cool: Slightly chilled dough makes shaping easier.
  3. Don’t Overbake: Cookies should be lightly golden, not browned, for a tender center.
  4. Smooth Ganache: Chop chocolate finely to ensure a silky, lump-free filling.
  5. Flavor Variations: Add a pinch of espresso powder or orange zest to the ganache for a flavor twist.

Variations to Try

  • Almond Version: Substitute hazelnuts with almonds for a different nutty flavor.
  • White Chocolate Ganache: Use white chocolate instead of dark for a sweeter filling.
  • Jam-Filled: Mix raspberry or apricot jam with ganache for a fruity twist.
  • Nut Garnish: Top with half a roasted hazelnut or almond for extra texture.
  • Mini Cookies: Make bite-sized versions for parties or cookie platters.
