What Ingredients are in Festive Sweet-Salty Cookie Bars?
These cookie bars combine the perfect blend of sweet and salty ingredients to create a treat that’s irresistibly festive and crowd-pleasing.
- 3 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup unsalted butter, at room temperature
- 1 cup granulated sugar
- 1 cup light brown sugar, firmly packed
- 3 large eggs, at room temperature
- 2 teaspoons vanilla extract
- 1 cup holiday-colored M&M’s, plus extra for topping
- 1 cup semi-sweet chocolate chips, plus extra for topping
- 1 cup salted pretzels, broken into pieces, plus extra for topping
Room temperature ingredients really matter here—especially the butter and eggs—as they’ll incorporate much better and give you that perfect chewy texture we’re all looking for in a good cookie bar.
How to Make these Festive Sweet-Salty Cookie Bars
Making these cookie bars is wonderfully straightforward, perfect for busy holiday baking sessions when you want maximum impact with minimal fuss. Start by preheating your oven to 350°F and pulling out your 9×13″ baking pan—a metal one gives you crispier edges, while glass creates a more even bake. Grease that pan generously; nothing ruins a perfect cookie bar like having it stick to the bottom.
The magic begins by creaming together 1 cup of room temperature unsalted butter with 1 cup of granulated sugar and 1 cup of firmly packed light brown sugar until the mixture is fluffy and smooth. This might take 3-4 minutes with an electric mixer, and trust me, it’s worth the time. A quality stand mixer can make this creaming process much more efficient and produce consistently better results for your holiday baking. Add in your 3 large eggs one at a time, letting each incorporate fully before adding the next, then pour in 2 teaspoons of vanilla extract.
In a separate bowl, whisk together 3 cups of all-purpose flour with 1 teaspoon of baking soda and 1 teaspoon of salt. Gradually add this dry mixture to your wet ingredients, mixing just until combined—nobody wants tough cookie bars from overmixing. Gently fold in 1 cup each of holiday M&M’s, semi-sweet chocolate chips, and those delightfully salty broken pretzels.
Now comes my favorite part—spreading that glorious cookie dough into your prepared pan. The dough will be thick, so grab a spatula or use slightly dampened fingers to press it evenly into all corners. Want that extra-festive look? Sprinkle additional M&M’s, chocolate chips, and pretzel pieces over the top before sliding the pan into your preheated oven for 35-40 minutes. You’re looking for light golden edges and a slightly soft center—they’ll continue to set as they cool. Remember, patience pays off here; let them cool completely before cutting into squares. Want to keep them soft for days? Store them in an airtight container with a slice of bread, a grandma-approved trick that works wonders.
What to Serve with Festive Sweet-Salty Cookie Bars
When you’ve got a batch of these irresistible sweet-salty cookie bars cooling on your counter, pairing them with complementary treats and beverages can turn a simple dessert into a memorable holiday spread.
I love serving these bars with a scoop of vanilla ice cream or a mug of hot chocolate topped with whipped cream. The warm spices of chai tea also balance the sweetness perfectly.
For a fancy dessert board, I arrange them alongside fresh berries, caramel sauce for dipping, and candied nuts. Can you imagine the delight on your guests’ faces?
Leftovers and Storage for these Festive Sweet-Salty Cookie Bars
After enjoying these treats with friends and family, you’ll want to properly store any remaining cookie bars to maintain their delicious flavor and texture. I recommend keeping them in an airtight container at room temperature for up to five days. The old baker’s trick of adding a slice of bread to the container works wonders here—it helps keep the bars soft and chewy, not hard and dry. Nobody wants a stale cookie bar, right?
For longer storage, these bars freeze beautifully. Just wrap them individually in plastic, then place in a freezer bag. They’ll stay fresh for about three months.
Festive Sweet-Salty Cookie Bars Substitutions and Variations
One of the best things about this cookie bar recipe is how flexible it’s with substitutions, letting you adapt it to whatever you have in your pantry or to accommodate dietary needs.
Can’t do dairy? Swap the butter for coconut oil. Need them gluten-free? Try a one-to-one gluten-free flour blend. The mix-ins are totally customizable too—think white chocolate chips, crushed potato chips, or holiday-themed candies like Reese’s Pieces for Halloween.
For a healthier version, I’d reduce the sugar by 1/4 cup and add chopped nuts for protein. Want more decadence? Drizzle caramel sauce over the top before baking.
Final Thoughts
These festive cookie bars have become my absolute go-to for holiday gatherings. The perfect balance of sweet chocolate, crunchy pretzels, and colorful M&M’s creates a treat that disappears faster than snow on a warm day.
Trust me, there’s something magical about that sweet-salty combination that keeps everyone coming back for seconds. And isn’t that what holiday baking is all about?
The best part? While they look impressive, they’re actually so simple to make. Pop that bread slice in the storage container—a little trick that works wonders. Your future self will thank you when they’re still perfectly soft days later.
