These cookies don’t just taste like the holidays, they feel like them—warm, nostalgic, and oh so indulgent.

Behind the Recipe

This recipe brings back memories of my grandmother’s kitchen where cookie tins were stacked high, each filled with carefully crafted bites of love. The thumbprint cookie was always my favorite. Something about pressing your thumb into the soft dough felt playful and intimate. The ganache was her modern touch—rich, glossy, and always perfectly pooled in the center. This version, with crunchy hazelnuts and smooth ganache, is my way of keeping that memory alive and adding a little extra magic.

Recipe Origin or Trivia

Thumbprint cookies, or “hallongrotta” as they’re called in Sweden, date back generations. Traditionally filled with raspberry jam, their transformation across cultures has led to countless variations—from fruit preserves to caramel to, of course, ganache. Hazelnuts and chocolate have long been a beloved pairing in European desserts, especially in Italy where gianduja reigns. This cookie is a delightful nod to that timeless flavor combination.

Ready to bring these beauties to life? Here’s exactly how:

1. Preheat Your Equipment:
   Set your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Combine Ingredients:
   In a large bowl, cream together the softened butter and sugar until light and fluffy. Add in the vanilla extract. Gradually mix in the flour and salt until a soft dough forms.
3. Prepare Your Cooking Vessel:
   Lightly toast the hazelnuts if not already toasted. Place chopped nuts in a shallow bowl and whisk egg whites in another.
4. Assemble the Dish:
   Scoop dough into 1-inch balls. Dip each ball into the egg whites, then roll in chopped hazelnuts. Place on baking sheet about 2 inches apart. Use your thumb or a rounded spoon to press a small indent into the center of each.
5. Cook to Perfection:
   Bake for 12–14 minutes or until edges are golden. If the centers have puffed, gently press them down again while still warm.
6. Finishing Touches:
   For the ganache, heat heavy cream in a small saucepan until just simmering. Pour over chocolate chips and butter in a bowl. Let sit 2 minutes, then stir until smooth.
7. Serve and Enjoy:
   Spoon ganache into the cookie centers and let set. Enjoy once the chocolate has firmed slightly.
