Whisk together the all-purpose flour, salt, and baking soda in a medium bowl.
1 Cup All-Purpose Flour, ¾ teaspoon Kosher Salt, ½ teaspoon Baking Soda
In a small skillet over medium-high heat, toast the rye flour until it is fragrant and a few shades darker, about 5 minutes, making sure that you're stirring often. Remove the skillet from the stove, add the butter and stir allowing the butter to melt into the rye flour before setting aside.
1 ¼ Cup Rye Flour, ¾ Cup Unsalted Butter
Mix together the sugar, eggs, molasses and vanilla in a large bowl. When the rye-butter mixture has cooled, stir into the wet ingredients. Add the dry ingredients and stir until everything is combined. Finally, stir in the chocolate chips and hazelnuts. Using a medium cookie scoop, scoop dough and place on a lined plate or small baking tray.
1 ¼ Cup Granulated Sugar, 2 Eggs, 1 Tablespoon Molasses, 1 Tablespoon Vanilla Extract, 1 Cup Dark Chocolate, 1 Cup Hazelnuts
Place your dough in the fridge overnight, or at a bare minimum for thirty minutes - this helps add to the texture, flavor and spreading of the cookie when they are ready to bake.
Prepare your baking sheets with parchment paper. Place the cookies about 2-inches apart on your baking sheets.
Preheat oven to 350 degrees and one sheet at a time, bake your cookies until the edges are firm and the centers are soft, about 12-14 minutes.
Cool your cookies on a wire rack, pour yourself a hefty glass of milk, dunk and enjoy!
