Ingredients

Hazelnuts

  • 3.5 oz. (100g) hazelnuts (skin on), toasted

Sugars and Liquids

  • 1/2 cup (100g) sugar
  • 1/2 cup (100g) brown sugar
  • 1/3 cup (80ml) water
  • 2 1/2 tbsp. rapeseed oil
  • 1 tsp. vanilla extract

Dry Ingredients

  • 2 1/2 cups (300g) all-purpose flour
  • 2 tsp. baking powder
  • 1 tsp. baking soda
  • 1 tsp. instant espresso powder

Chocolate & Toppings

  • 4.2 oz. (120g) semi-sweet chocolate, roughly chopped
  • some flaky sea salt (optional)

Instructions

  1. Toast hazelnuts: Preheat the oven to 180°C (350°F). Spread hazelnuts on a baking sheet and toast for 10-12 minutes until golden and fragrant. Allow to cool, then rub with a kitchen towel to remove most skins. Chop half roughly and grind the other half in a mixer to obtain ground hazelnuts.
  2. Prepare wet and dry mixtures: In a large bowl, mix sugar, brown sugar, water, rapeseed oil, and vanilla extract until well combined. In another bowl, whisk together flour, baking powder, baking soda, espresso powder, and ground hazelnuts.
  3. Combine dough: Add dry ingredients to wet mixture and mix until just combined. Fold in most of the roughly chopped hazelnuts and semi-sweet chocolate, reserving some for decoration. Cover and refrigerate the dough for at least 2 hours or overnight for best results.
  4. Preheat oven and prepare baking sheet: Heat oven to 200°C (390°F). Line a baking sheet with parchment paper.
  5. Shape and decorate cookies: Divide dough into 12-13 portions and shape each into a rough ball. Arrange on baking sheet with space between each. Decorate tops with reserved chopped hazelnuts and chocolate pieces, and optionally sprinkle with flaky sea salt.
  6. Bake cookies: Bake in preheated oven for about 12 minutes until edges are set and surfaces are cracked but still soft.
  7. Cool cookies: Remove from oven and cool on baking sheet briefly, then transfer to a wire rack to cool completely. Repeat with remaining dough.

Notes

  • Chilling the dough is essential for texture and flavor development; it also makes shaping easier.
  • Using toasted hazelnuts enhances nuttiness and aroma in the cookies.
  • Flaky sea salt is optional but adds a nice contrast to the sweet chocolate and espresso flavors.
  • Store cookies in an airtight container to maintain crispness.
  • For a stronger espresso flavor, you can increase the instant espresso powder slightly but avoid overpowering the chocolate.
