Whisk the dry ingredients:
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Combine wet and dry:
Slowly mix the dry ingredients into the wet mixture until just combined—don’t overmix.
Fold in the magic:
Stir in the chocolate chips, white chocolate chips, and festive sprinkles. Add peppermint pieces if using.
Scoop the dough:
Roll or scoop tablespoon-sized balls onto the prepared baking sheet, leaving about 2 inches between cookies.
Bake:
Bake for 10–12 minutes, or until the edges are lightly golden and the centers look slightly soft. They’ll firm up as they cool.
Cool:
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack.
Tips for Extra Holiday Charm
✨ Sprinkle additional Christmas sprinkles on top right before baking.
✨ Drizzle melted white chocolate over cooled cookies for a snow-kissed finish.
✨ Add a dash of cinnamon or nutmeg to the dough for warm spice notes.
