In a large mixing bowl whisk the flour, cornstarch, baking powder, baking soda, cinnamon and salt until well combined. Set aside for now.
2½ cups (300 g) all purpose flour, 2 teaspoons cornstarch, 1 teaspoon baking powder, ½ teaspoon baking soda, 1 teaspoon cinnamon, optional
In the bowl of a stand mixer fitted with paddle attachment, cream together the cubes of cold butter, light brown sugar, granulated sugar and honey on medium speed for 2 - 3 minutes or until the butter and sugars are well combined.
¾ cup (170 g) cold unsalted butter, cubed, ¾ cup (150 g) granulated sugar, ¼ cup (50 g) light brown sugar, ¼ cup (60 ml) honey
On low, cream in the egg, egg yolk and vanilla extract until smooth and well combined. Mix the dry ingredients into the wet until just combined. Cover the cookie dough and transfer to the fridge to chill for 30 - 60 minutes. 1 large egg, room temperature, 1 large egg yolk, room temperature, 2 teaspoons (10 ml) vanilla extract
Preheat the oven to 375 F (190 C) for about 20-30 minutes before baking the cookies. Line a large baking sheet with parchment paper. Pour ¼ cup (50 g) of sugar into a small bowl if you would like to roll the cookies in sugar before baking. Using a medium cookie scoop (2 tablespoons, 30 ml), scoop the honey sugar cookie dough, roll the dough ball into the sugar and place the honey cookie dough balls onto the lined baking sheet about 3 inches (8 cm) apart. ¼ cup (50 g) granulated sugar for rolling, optional
Bake at 375 F (190 C) for 9 - 10 minutes or until the edges of the cookies are set and the centers are slightly puffed. Cool the chewy honey sugar cookies on the baking sheet for 5 minutes. Then transfer to a cooling rack to cool completely to room temperature.
