Spelt chocolate hazelnut sandwich cookies pair soft cocoa cookies made with whole spelt flour with a creamy chocolate hazelnut filling in between. The texture stays soft in the center with a slight chew at the edge.
Spelt flour gives the dough a nutty base note that pairs well with cocoa and hazelnut. The dough comes together in one bowl, so cleanup stays simple.
You chill the dough for 30 minutes before baking. This step keeps the cookies from spreading too thin in the oven.
These cookies work well as a make-ahead treat. Bake the cookies a day early and fill them closer to serving, so the filling stays glossy instead of soaking into the crumb.

Ingredient Notes
- spelt flour: Whole spelt flour gives a nuttier flavor and slightly denser crumb than all-purpose flour. You can swap in all-purpose at the same weight if that’s what you have.
- cocoa powder: Use natural unsweetened cocoa powder here, not a Dutch-process one, since it keeps the dough from tasting flat.
- butter: Soften the butter at room temperature until it gives slightly when pressed. Cold butter won’t cream properly with the sugar.
- hazelnuts: Toast the hazelnuts first to bring out the flavor, then chop them fine so they don’t tear the dough when rolling.
- chocolate hazelnut spread: Any jarred chocolate hazelnut spread works, including dairy-free versions. Let it sit at room temperature so it spreads without tearing the cookie.
- egg: Use one large egg at room temperature, so it blends into the butter mixture smoothly instead of curdling it.

Instructions
- Heat the oven to 180 C / 350 F. Line two sheet pans, 33 x 46 cm / 13 x 18 inch, with parchment.
- Whisk the spelt flour, cocoa powder, baking powder, and salt together in a bowl. Set aside.
- In a large mixing bowl, cream the butter, granulated sugar, and brown sugar with a hand mixer for 2 to 3 minutes, until light and fluffy.
- Beat in the egg and vanilla extract until smooth.
- Add the dry ingredients to the wet mixture and mix on low until the dough just comes together. Fold in the chopped hazelnuts.
- Cover the bowl and chill the dough for 30 minutes, until it feels firm to the touch.
- Scoop the dough into 27 g balls, about 24 total. Roll each into a ball and place on the sheet pans, spaced 5 cm / 2 inches apart, then flatten slightly with your palm.
- Bake one pan at a time for 10 to 12 minutes, until the edges look set and the surface looks dry. The centers should still look soft, they firm up as the cookies cool.
- Cool the cookies on the pan for 5 minutes, then transfer to a wire rack to cool completely.
- Spread about 1 tbsp chocolate hazelnut spread on the flat side of half the cookies. Top with the remaining cookies, flat side down, and press gently to sandwich.
