1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
2. In a large bowl, beat butter and both sugars until light and fluffy (2–3 minutes).
3. Beat in egg and vanilla until smooth.
4. In another bowl, whisk flour, baking powder, and salt. Gradually add to wet ingredients, mixing until just combined.
5. Gently fold in M&Ms (don’t overmix to prevent color bleed).
6. Scoop tablespoon-sized balls of dough and place on trays (they spread slightly).
7. Bake 9–11 minutes, until edges are lightly golden.
8. Let cool on the tray 5 minutes—they’ll firm up as they cool. Then transfer to a wire rack.

✨ Perfect for:
• Cookie exchanges 🎁
• Santa’s plate 🎅
• DIY edible gifts in festive tins 🎀

💡 Make ahead: Dough freezes well—bake from frozen (+1–2 mins).
