In a large bowl, beat butter, sugar, and brown sugar together until light and fluffy.

Beat until the mixture becomes smooth.
4. Mix Dry Ingredients
In another bowl whisk together:

Gradually add the dry ingredients to the wet mixture.
Mix until a soft dough forms.

7. Shape the Cookies
Scoop about 1–2 tablespoons of dough and place them on the baking sheet, leaving space between each cookie.
8. Bake
Bake for 10–12 minutes until the edges are set but the centers remain soft.
9. Cool and Serve
Let the cookies cool for 5 minutes on the baking sheet, then transfer to a wire rack.
✅ Tip: Sprinkle extra crushed peppermint on top right after baking for a bakery-style look.
