Ingredients:
- 1 cup (225g) unsalted butter
- 1 cup (200g) brown sugar, packed
- 1/4 cup (50g) granulated sugar
- 1 large egg, room temperature
- 1/3 cup (105g) pure maple syrup
- 1 tsp maple extract
- 1 tsp vanilla extract
- 2.75 cups (345g) all-purpose flour
- 2 tsp cornstarch
- 1 tsp baking soda
- 0.5 tsp fine sea salt
- 0.25 cup (56g) unsalted butter, for icing
- 1.5 cups (180g) powdered sugar, sifted
- 2.5 tbsp (50g) pure maple syrup, for icing
- 1.5 tbsp (22g) heavy cream
- 1 pinch fine sea salt
Instructions:
- Brown the butter. Place 1 cup of butter in a light colored skillet over medium heat. Whisk constantly as it foams and develops brown specks. Note: The foam will clear right before the browning starts.
- Cool the fat. Once it smells nutty and reaches a toasted almond color, transfer to a heat proof bowl. Chill in the refrigerator for 20 minutes until it reaches a soft, spreadable consistency.
- Cream the base. In a stand mixer, cream the cooled browned butter with the brown sugar and granulated sugar on medium high speed for 2 to 3 minutes until pale and fluffy.
- Emulsify the wet ingredients. Add the egg, 1/3 cup maple syrup, maple extract, and vanilla extract. Beat until fully incorporated and smooth.
- Whisk the dry goods. In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt.
- Combine the mixtures. Gradually add the dry ingredients to the wet mixture on low speed, mixing only until no flour streaks remain. Note: Overmixing at this stage creates a tough cookie.
- Portion and chill. Scoop 1.5 to 2 tablespoon rounds of dough onto a tray. Chill in the refrigerator for 30 minutes until firm to the touch.
- Prepare for baking. Preheat your oven to 350°F (175°C). Place chilled dough rounds on parchment lined baking sheets.
- Bake the cookies. Bake for 10 minutes until the edges are just set but the centers remain soft.
- Glaze the tops. Brown the remaining 1/4 cup of butter. Whisk in powdered sugar, 2.5 tablespoons maple syrup, heavy cream, and a pinch of salt until the icing is velvety and glossy. Drizzle over cooled cookies.
