Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
Step 2: In a mixing bowl, combine the softened butter, granulated sugar, and powdered sugar. Cream until light and fluffy, about 2-3 minutes.
Step 3: Add the beaten egg, Butter Buds, vanilla extract, and almond extract to the creamed mixture. Mix until well incorporated.
Step 4: In a separate bowl, whisk together the flour, cream of tartar, baking soda, and salt. Gradually add to the wet ingredients, mixing just until combined.
Step 5: Gently fold in the finely chopped almonds until evenly distributed.
Step 6: Drop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper, leaving space for spreading.
Step 7: Bake for 12-15 minutes or until edges are lightly golden. Monitor closely as baking times may vary.
Step 8: Allow cookies to cool on the baking sheet for a few minutes before transferring to a cooling rack.
