Homemade chocolate-hazelnut filling joins crunchy hazelnut cookies in to create a delicious, melt-in-your-mouth cookie sandwich.
Ingredients
For cookies:
  • 150 g hazelnuts, roasted and ground (Note 1)
  • 175 g coconut oil (softened, not completely melted)
  • 150 g clear honey
  • 1 egg and 1 egg yolk
  • 1 tsp vanilla extract
  • 325 g gluten free flour
  • ½ tsp baking powder
  • ½ tsp bicarbonate of soda
  • pinch of salt
  • 1 tsp cinnamon

For assembling:
  • 1 tbsp clear honey
  • melted chocolate (Note 2)
  • 50 g hazelnuts, roasted and ground
Instructions
For cookies:
  1. Pre-heat the oven to 350F (175C) and line a baking tray/sheet with baking/greaseproof paper.
  2. Cream together softened coconut oil, honey and vanilla extract.
  3. Add the egg and egg yolk, mix thoroughly.
  4. In a separate bowl, sift together gluten free flour, baking powder, baking soda, salt and cinnamon. Mix in the ground hazelnuts.
  5. Add the flour mix to the wet ingredients, and mix well until a smooth cookie dough comes together. The dough will appear a bit oily – it's supposed to be like that!
  6. Shape individual portions of cookie dough, roughly 1 – 1½ tbsp in amount, into balls.
  7. Place the cookie dough balls onto the baking tray, leaving about ½ inch (about 1.5 cm) between them. Flatten them (very slightly).
  8. Bake in the pre-heated oven at 350F (175C) for about 12 minutes, or until golden brown around the edges.
  9. Leave the baked cookies to cool before sandwich cookie assembly.
For homemade Nutella filling:
  1. Combine all ingredients in a blender and blend until smooth (or slightly chunky/crunchy, depending on the strength of your blender – it will be delicious in all cases).
  2. The "Nutella" will be dense and gooey, and you will be able to shape it using your hands (or a spoon)
For assembly:
  1. Smear a small amount of honey on the bottom part of two cookies.
  2. Shape the "Nutella" filling into a ball roughly the size of the cookie balls before baking.
  3. Sandwich the "Nutella" filling between the two cookies, and repeat until no cookies and/or filling remains.
  4. Dip half of each sandwich cookie into the melted chocolate, letting any excess drip down.
  5. Dip the chocolate-covered half into the remaining ground roasted hazelnuts.
  6. Let the chocolate to set, and enjoy!
  7. The sandwich cookies keep well in a closed container in a cool dry place for about a week (but I give them a day, at most).
Notes
Note 1: Roast the hazelnuts in a pan on the hob at medium to high heat for 5 – 7 minutes, until dark golden brown. Alternatively, you can roast them in the oven heated to 390F (220C) in a baking tray for about 10 minutes. If not using blanched hazelnuts, peel the skin off the hazelnuts before they cool completely. When cooled down, grind the hazelnuts into a relatively fine powder, using a blender/mixer.

Note 2: You can simply melt store-bought (sugar free!) chocolate of your preference, or follow the procedure for my raw vegan chocolate truffles to make your own (but WITHOUT adding the water!).
