The quest for the perfect, stress-free holiday treat ended the moment I pulled my first pan of these Festive Christmas Cookie Bars from the oven. My kitchen was wrapped in the warm, buttery scent of vanilla and toasty brown sugar, punctuated by the cheerful, colorful promise of melted M&Ms and sprinkles. I remember the feeling of sheer joy—and relief—as I sliced into them, revealing a dense, soft, chewy interior studded with pockets of white chocolate and vibrant candy shells. These bars are my holiday kitchen victory: all the nostalgic flavor of classic Christmas cookies, but simpler, faster, and perfect for sharing. They capture the very essence of holiday baking magic in every single square.

Ingredients
- 1 cup (2 sticks) unsalted butter, melted and slightly cooled
- 1 ½ cups packed light brown sugar
- ½ cup granulated sugar
- 2 large eggs + 1 egg yolk, at room temperature
- 1 tablespoon pure vanilla extract
- 3 cups bread flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- 1 teaspoon salt
- 1 ½ cups Christmas M&Ms
- 1 cup white chocolate chips
- ½ cup festive sprinkles (plus more for topping)
Let’s talk about a few key ingredients that make these bars special. Using bread flour instead of all-purpose was a game-changer I discovered after some testing; its higher protein content gives these bars a wonderfully chewy, substantial texture that doesn’t fall apart. Don’t skip the extra egg yolk—it adds incredible richness and softness. And for the butter, make sure it’s just melted, not hot. I once rushed it and poured in hot butter, which started to cook the eggs. Letting it cool for 5-10 minutes makes all the difference. Finally, using pure vanilla extract over imitation is non-negotiable here; its warm flavor is the soul of the dough.(See the next page below to continue…)
