Prepare the Wet Ingredients: Add the maple syrup, dark brown sugar, vegetable oil, ground cinnamon, salt, and egg yolk to a mixing bowl fitted with a paddle attachment. Mix until the ingredients are thoroughly combined.
Mix the Cookie Dough: Add the all-purpose flour, almond meal, baking powder, and baking soda to the bowl. Mix until the ingredients come together to form a soft dough.
Chill the Dough: Cover the dough and refrigerate for approximately 1 hour to allow it to firm up before shaping.
Prepare the Oven and Trays: Preheat the oven to 170°C (338°F). Line the baking trays with baking paper.
Shape the Cookies: Take portions of the chilled dough and roll them into walnut-sized balls.
Coat the Dough Balls: Place the powdered sugar in a small bowl. Roll each dough ball in the sugar until it is generously coated.
Arrange the Cookies: Place the coated dough balls on the prepared baking trays, leaving space between them so they can spread during baking.
Bake the Cookies: Bake at 170°C (338°F) for 10–14 minutes, or until the cookies develop their characteristic crinkled surfaces and appear set.
Cool the Cookies: Remove the trays from the oven and allow the cookies to cool completely at room temperature before serving.
