Ingredients List
- Butter: 1/2 cup unsalted, softened - leave it out about an hour
- Brown Sugar: 2 cups packed - this creates that amazing chewiness!
- Eggs: 2 large ones, cold from the refrigerator works fine
- Vanilla: 1 teaspoon - using pure extract really counts here
- Salt: 1/2 teaspoon to cut through sweetness
- Baking Powder: 1 teaspoon for just enough rise
- Flour: 2 cups all-purpose - nothing fancy needed
- Holiday M&Ms: 1 cup of festive red and green ones
- Sprinkles: 1/2 cup Christmas colors - jimmies work best
How To Make Holiday Cookie Bars
- Prep Time
- Heat your oven to 350°F and put foil in a 9x13 pan. Don't forget to spray it with cooking spray so nothing sticks!
- Create Your Foundation
- Cream your butter and brown sugar together until well mixed. Don't stress if it looks a bit grainy at first!
- Incorporate Liquids
- Toss in your eggs and vanilla. Keep mixing until everything looks smooth and blended.
- Add Dry Components
- Toss in salt and baking powder, then slowly add flour. Don't overmix here - just until everything comes together.
- Add Some Color
- Gently stir in most M&Ms and sprinkles - keep some aside to put on top!
- Fill Your Pan
- Push the mixture into your pan (it'll be pretty thick!). Scatter remaining M&Ms and sprinkles on top for a pretty finish.
- Into The Oven
- Bake for 22-25 minutes. You want the edges slightly golden, but the center might still look soft - that's how you get gooey bars!
Foolproof Results
You know what's awesome about these bars? They never fail! No complicated steps or fancy tools needed - just mix stuff together and bake. They come out soft and chewy every single time, and the brown sugar gives them this amazing almost-caramel flavor you'll love.
Seasonal Variations
What's cool about this recipe? You can adapt it for any time of year! Just swap out the candy colors and sprinkles - try orange and black for Halloween, pink and red for Valentine's, or light pastels for Easter. Same tasty treat, completely different look!
Pro Tricks
Wanna know my top trick for these bars? Let that foil hang over the edges a bit when lining the pan - you can lift the whole thing out so easily. And here's another good one: take them out when they're slightly underdone. They'll finish cooking as they cool, giving you that perfect chewy texture.

Storage Advice
After your bars cool down, put them in an airtight container. They'll stay nice and chewy for about a week - if anyone leaves them alone that long! Want to prep ahead? They freeze really well for up to a month. Just wrap them tightly and thaw whenever you want a sweet treat.
Custom Touches
Feel free to switch things up with these bars! Try adding some crushed nuts, use different candy pieces, or even pour melted chocolate over the top. The base recipe is so reliable, it's hard to go wrong. Get creative and start your own holiday baking tradition!
