Ingredients

Scale

Cookie Bar Base

  • 1/2 cup unsalted butter, softened
  • 2 cups brown sugar
  • 2 eggs
  • 1 tsp vanilla extract
  • 1/2 tsp salt
  • 1 tsp baking powder
  • 2 cups all-purpose flour

Festive Add-Ins

  • 1 cup Christmas M&Ms
  • 1/4 cup Christmas jimmies sprinkles

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper to prevent sticking and make removal easy after baking.
  2. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and brown sugar together until the mixture is creamy and smooth. This ensures a tender and flavorful base.
  3. Add Wet Ingredients: Incorporate the eggs one at a time along with the vanilla extract. Continue mixing until all wet ingredients are fully combined and the batter is smooth.
  4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, salt, and baking powder. This evenly distributes the leavening agent and seasoning.
  5. Mix Dry into Wet: Gradually add the dry ingredients to the wet mixture. Stir just until the dough comes together — avoid overmixing to keep the bars soft and tender.
  6. Fold in Festive Add-Ins: Gently fold in the Christmas M&Ms and jimmies sprinkles, distributing them evenly throughout the dough.
  7. Press and Bake: Evenly press the dough into the prepared baking pan. Bake in the preheated oven for 22 to 25 minutes, or until the edges turn golden and the center looks set but still soft.
  8. Cool and Slice: Allow the cookie bars to cool completely in the pan. Use the parchment paper to lift the bars out, then slice into squares for serving.

Notes

  • Do not overmix the dough once the dry ingredients are added to avoid tough cookie bars.
  • Make sure to cool the bars completely before slicing to keep them intact and prevent crumbling.
  • You can substitute the Christmas M&Ms with other holiday-themed candies or chocolate chips if preferred.
  • Store bars in an airtight container at room temperature for up to 5 days, or freeze for longer storage.
  • Line the pan with parchment paper extending over the edges to easily lift out the entire slab after baking.
