Ingredients
  

  • 200 g plain flour (all-purpose flour) (approx. 1.6 cups)
  • 150 g dark chocolate chips (approx. 3/4 cups)
  • 100 g hazelnuts (approx. 2/3 cups)
  • 225 g unsalted butter (room temperature) (approx. 1 cup)
  • 250 g coconut sugar (approx. 1 cup)
  • 1/2 tsp vanilla extract
  • 1 large egg
  • 1 egg yolk
  • 200 g rolled oats (old-fashioned oats) (approx. 1 1/4 cup)
  • 1 tsp bicarbonate of soda (baking soda)
  • 1 pinch salt

Instructions
 

  • Preheat the oven to 180°C (356°F)
  • Lay the hazelnuts and oats on two different oven trays.
  • Bake them in the heated oven for about 10-15 minutes. Just to slightly toast them.
  • Take them out of the oven and let them cool off completely.
  • In a large bowl, cream the butter, coconut sugar, and vanilla extract. For best results, use an electric mixer.
  • Add in the eggs and mix well.
  • Mix the salt and bicarbonate of soda in the flour
  • Start incorporating the flour mixture into the wet ingredients.
  • In a food processor, pulse the hazelnuts until roughly chopped.
  • Using a wooden spoon or spatula, fold in the oats, chocolate chips, and ground hazelnuts.
  • Using a cookie scoop or a spoon, scoop out the cookie batter and form cookie dough balls.
  • Place them on a baking sheet or baking tray lined with parchment paper.
  • Bake cookies for about 15 minutes, or until golden brown and have crispy edges.
  • Take the cookies out and place them on a wire rack to cool off.
  • Once cool, they will become more crispy.
  • Serve and enjoy!

Notes

  • Avoid using other types of oats than the ones mentioned, for the best crunchy texture. 
  • Use chocolate chunks instead of chocolate chips for a more chewy middle.
  • Replace the chocolate with raisins if you don't like chocolate.
  • If you prefer a chewy texture, skip the toasting of hazelnuts and oats, and replace the coconut sugar with brown sugar.
  • If you like a more intense chocolate flavor, add a tablespoon of cocoa powder to the mixture. Reduce the flour amount accordingly.
  • Keep an eye on the cookies while baking them. You want to avoid burning them as they will become bitter.
