Beat the room temperature butter with both sugar until creamy and smooth.
1 cup Butter, 1 cup Light Brown sugar, ½ cup Granulated sugar
Add in the egg, yolk, vanilla and almond extract. Mix well until the mixture is evenly smooth.
1 Egg, 1 Egg yolk, 1 teaspoon Almond extract, 2 teaspoon Vanilla extract
Sift all dry ingredients using a spatula and gently fold them into the mixture.
2 cups All-purpose flour, 1 cup Almond flour, ½ teaspoon Baking powder, ¼ teaspoon Baking soda, ¼ teaspoon Salt
Use a medium-sized ice cream scoop to make small balls of cookie dough. Roll the cookie dough balls in the silvered almond and place them on a baking sheet. Chill them for an hour.
1 cup Silvered almond
In the meantime, preheat the oven to 350F. Line a large baking sheet with Baking Mat or parchment paper.
Place the cookie dough balls on the mat and leave two 2-inch gaps between them. Bake them for 10-12 minutes or until they look set on the edges and the almonds look slightly golden brown. Immediately after removing them from the oven, go around them to soften their edges, and top them with more almond flakes if needed.
2 tablespoon powdered sugar
Let them cool down on the baking sheet for 10 minutes, then transfer them to the cooling rack to cool down completely. Sprinkle their top with powdered sugar.
