I whip up these addictive cookie bars every Christmas that fill my kitchen with happiness. They're packed with holiday-colored M&Ms, gooey caramel and snappy pretzels - my favorite when I need something impressive yet straightforward. The mix of soft, sweet and salty makes everyone grab for these colorful treats when they appear on my holiday dessert tray.
Why These Treats Stand Out
The best thing about these bars is how they deliver everything you want from cookies without dealing with spoonfuls of dough. They've got that perfect consistency - soft and gooey inside with surprising crunches from candy and pretzels. And that caramel really makes them something special. They're my go-to when holiday baking gets hectic.
Essential Components
- Caramel: I grab Kraft or Werther's and chop them small so they create delicious sweet spots throughout.
- Semi-Sweet Chocolate Chips: These bring that familiar cookie flavor, and sometimes I throw in a mix of dark and milk varieties.
- M&M's: The green and red ones really bring Christmas cheer to these treats.
- Pretzels: Just snap them into chunks for that wonderful salt crunch.
- Butter: Stick with unsalted and melted for the softest bar texture.
- Sprinkles: Red and green jimmies add extra holiday flair when I want them to look festive.
Simple Preparation Guide
- Ready Your Add-ins
- I start by cutting those caramels and snapping pretzels into smaller bits.
- Create Your Base
- Combine your melted butter with sugars, drop in eggs and vanilla. Gently add dry stuff until just mixed, then fold in all those tasty extras.
- Set Up Your Tray
- Spread everything into your paper-lined pan and flatten with a measuring cup bottom. Scatter some extra goodies on top for looks.
- Cook Through
- Slide it into a 350°F oven around 16 minutes until you see golden edges. Cool them right in the pan.
- Cool and Cut
- For clean-looking pieces, I always cool them in the fridge first. Makes cutting so much easier.
Storage Solutions
These goodies stay soft for 3 days in a box on your counter, or nearly a week when refrigerated. You can make them ahead and freeze them for a couple months too. Just know that those pretzels might soften over time, so I typically save those batches for eating soon.
Smart Baking Tricks
Want clean-cut squares? Stick the whole pan in the freezer briefly before cutting. I always warm my knife under hot water, dry it off and then slice. Try different mix-ins too - white chocolate bits or butterscotch work great. A tiny bit of sea salt on top really wakes up all the flavors.
Seasonal Variations
I love how flexible these bars are - I make them throughout the year just swapping M&M colors for whatever holiday's coming. At Christmas, I sometimes mix in smashed candy canes or add white chocolate drizzles. You can toss in whatever festive treats you fancy.
Great for Sharing
These treats always get compliments at cookie exchanges and holiday gatherings. Their bright colors catch attention right away and their taste keeps folks coming back. Put them in cute boxes with some tissue and you've got wonderful handmade presents.
