In the bowl of your stand mixer, cream together the 1 cup unsalted butter. ¾ cup brown sugar and ¼ cup granulated white sugarwith the paddle attachment on medium speed until smooth.
Lower the mixer speed to stir and add in the 1 egg, 1 egg yolk, 3 tablespoons amaretto, and 2 teaspoon almond extract. Mix until thoroughly combined, about 30 seconds.
Add the 2 ½ cups bread flour, ½ teaspoon kosher salt, and 1 teaspoon baking soda, Stir until just combined.
Fold in the 1 cup semi-sweet chocolate chips and ½ cup slivered almonds with a spatula.
Wrap the dough in wax paper and refrigerate for at least 2-3 hours.
Preheat oven to 375°F (190°C). Remove the dough from the refrigerator and roll it into balls, about 2 tablespoons of dough each. The dough may be a bit crumbly but will become smoother as you roll it.
Place the balls on a baking sheet leaving at least 2 inches in between each cookie. Flatten the balls slightly with your hand to help them spread.
Bake for 10 - 12 minutes or until the edges are lightly browned. Allow the cookies to cool for at least 5 minutes before transferring them to a wire rack to cool completely.
