Gooey Christmas Cookie Bars

Ingredients

  • ½ cup all-purpose flour
  • ¼ tsp baking powder
  • Pinch of salt
  • 4 tbsp unsalted butter, melted
  • ¼ cup brown sugar
  • 2 tbsp granulated sugar
  • 1 egg yolk
  • ½ tsp vanilla extract
  • ¼ cup mini chocolate chips
  • 2 tbsp holiday M&M minis or red/green sprinkles

Optional swap: Use white chocolate chips or chopped candy canes for a more festive flavor.

Steps

  1. Whisk the flour, baking powder, and salt in a small bowl. It keeps the texture light.
  2. Stir the melted butter with both sugars until glossy and smooth this is what makes the bars so gooey.
  3. Mix in the egg yolk and vanilla, and don’t worry if the batter looks thick; it should.
  4. Fold in the chocolate chips and M&M minis gently so the candy stays whole.
  5. Press the batter into a mini baking dish (about 4×6 inches or similar) lined with parchment.
  6. Bake at 350°F for 12–15 minutes, just until the center looks set but still soft.
  7. Cool 10 minutes before slicing into tiny squares they hold their shape better once rested.

Chef’s Tips

  • For extra gooey bars, pull them from the oven when the center still jiggles slightly.
  • Lightly dampen your fingertips to press the dough evenly without sticking.
  • These bars stay soft for 3 days when stored in an airtight container.

Variations

  • White Chocolate Cranberry: Swap chips for white chocolate and add 1 tbsp dried cranberries.
  • Peppermint Crunch: Fold in crushed candy cane pieces.
  • Gingerbread Glow: Add ¼ tsp ground ginger and a pinch of cinnamon to the batter.
