Christmas Cookie Bars Recipe
Introduction
These Christmas Cookie Bars are a festive twist on classic cookies, packed with colorful M&Ms and sprinkles. They’re easy to make, buttery, and perfect for holiday gatherings or cozy winter treats.

Ingredients
- 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
- 1 cup Christmas M&Ms
- 1/4 cup Christmas jimmies sprinkles
Instructions
- Step 1: Preheat the oven to 350°F and line a 9×13-inch baking pan with parchment paper.
- Step 2: In a large mixing bowl, beat the butter and brown sugar together until creamy. Add the eggs and vanilla extract, then mix until smooth and well combined.
- Step 3: In a separate bowl, whisk together the flour, salt, and baking powder. Gradually add these dry ingredients to the wet mixture and stir just until the dough forms. Avoid overmixing.
- Step 4: Fold in the Christmas M&Ms and sprinkles gently. Press the dough evenly into the prepared pan.
- Step 5: Bake for 22–25 minutes, or until the edges are golden and the center looks set.
- Step 6: Allow the cookie bars to cool completely in the pan. Use the parchment paper to lift them out, then slice into squares and serve.
Tips & Variations
- For extra crunch, add chopped nuts like pecans or walnuts to the dough.
- Swap out Christmas M&Ms for any festive chocolate candies you prefer.
- If you like a softer texture, slightly underbake the bars by a minute or two.
- Use white or brown sugar alone if you don’t have both; brown sugar adds more moisture and depth.
Storage
Store the cookie bars in an airtight container at room temperature for up to 5 days. For longer storage, freeze the bars wrapped tightly for up to 3 months. To reheat, let thaw at room temperature or warm briefly in the microwave.

- 1 tsp baking powder
- 2 cups all purpose flour

Instructions
- Preheat and Prepare Pan: Preheat the oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper to prevent sticking and ensure easy removal of the cookie bars.
- 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 creates a rich base for the cookies.
- Add Eggs and Vanilla: Incorporate the eggs and vanilla extract into the butter-sugar mixture, mixing well until fully combined and smooth.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, salt, and baking powder to evenly distribute the leavening agents and salt throughout the flour.
- Mix Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, stirring just until the dough comes together. Avoid overmixing to keep the bars tender.
- Add Festive Mix-ins: Gently fold in the Christmas M&Ms and jimmies sprinkles, ensuring an even spread of candy and color throughout the dough.
- Press Dough and Bake: Evenly press the dough into the prepared baking pan. Bake for 22 to 25 minutes until the edges are golden brown and the center appears set.

Notes
- For easier slicing, chill the bars in the refrigerator for 30 minutes after cooling.
- You can substitute the Christmas M&Ms with any colorful chocolate candies of your choice.
- Be careful not to overbake to maintain a soft and chewy texture.
