Soften butter properly for best texture. Use pure peppermint extract for best flavor. Crush peppermint candies finely for even flavor distribution. Use parchment paper or silicone mats to prevent sticking. Watch baking time carefully to avoid overbaking. Rolling dough balls in sugar is optional for a sparkle effect. Variations include adding chocolate drizzle, using gluten-free flour, or making vegan adaptations.
