Step 1: Preheat your oven to 350°F (175°C).
Step 2: In a large mixing bowl, cream together the softened butter, granulated sugar, brown sugar, and almond paste until light and fluffy, about 2-3 minutes.
Step 3: Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
Step 4: In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this mixture to the wet ingredients until just combined.
Step 5: Fold in the chocolate chips and toasted slivered almonds until evenly distributed.
Step 6: Drop rounded balls of dough onto a baking sheet lined with parchment paper, spacing them about 2 inches apart. Bake for 10-12 minutes.
Step 7: Let the cookies cool on the baking sheet for about 5 minutes before transferring to a cooling rack.
