Christmas Oatmeal Cookie Bars

These Christmas Oatmeal Cookie Bars are my go-to festive treat each holiday season—chewy, spiced, and studded with cranberries. You won’t resist sneaking a square (or two!) straight from the pan.

Ingredients
  

  • 2 cups old-fashioned rolled oats Bob’s Red Mill recommended
  • cups all-purpose flour or 1:1 gluten-free blend
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon sea salt
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg optional, for extra warmth
  • 1 cup unsalted butter melted and slightly cooled (grass-fed if preferred)
  • ¾ cup light brown sugar packed
  • ½ cup granulated sugar
  • 1 large egg room temperature
  • 1 teaspoon pure vanilla extract
  • ¾ cup dried cranberries or cherries
  • ½ cup dark chocolate chips Ghirardelli
  • ½ cup chopped pecans or walnuts optional

Instructions
 

  • Preheat your oven to 350°F (175°C). Line a 9×13-inch pan with parchment paper, letting the edges hang over for easy lift-out. This trick helps keep bars intact.
  • In a medium bowl, whisk together oats, flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Set aside.
  • In a large bowl, whisk melted butter with brown sugar and granulated sugar until smooth and glossy.
  • Mix in the egg and vanilla extract until the batter is smooth.
  • Fold the oat-flour mix into the butter mixture until combined.
  • Gently fold in cranberries, chocolate chips, and nuts.
  • Transfer the dough to the prepared pan and press into an even layer.
  • Bake for 20–25 minutes until golden brown. The center should be set.
  • Let the bars cool completely in the pan before slicing into 18–20 squares.
  • Enjoy the bars at your next gathering or store them for later.

Notes

Store cooled bars in an airtight container for up to 5 days or freeze for up to 2 months.
