Step 1: Preheat your oven to 350°F (175°C). This is crucial for even baking.
Step 2: In a large mixing bowl, beat the softened butter and sugar together using an electric mixer until light and fluffy, about 3-5 minutes.
Step 3: Mix in the vanilla extract until well incorporated.
Step 4: Gradually add the all-purpose flour, mixing on low speed until the dough begins to come together. Add milk if the dough seems too dry.
Step 5: Turn the dough out onto a lightly floured surface, roll it to about ½ inch thick, and cut into desired shapes.
Step 6: Place the shaped cookies onto a baking sheet lined with parchment paper, spaced apart.
Step 7: Bake for 15-20 minutes until the edges are lightly golden.
Step 8: Cool on the baking sheet for a few minutes before transferring to a wire rack.
