This year I'm changing up my usual holiday baking routine and making things easier on myself by getting out my 9x13-inch pan and sticking with bar cookies. These underrated treats pack in layer upon layer of sweet goodness, and I only need to make one batch to feed a crowd.

Here are 10 of my favorite bar cookie recipes. From kid-friendly PB&J crumble bars to more elegant white chocolate-cranberry bars, there's something here for everyone.

Two kinds of bars — candy and cookie — come together in a superhero-worthy pairing that, yes, truly satisfies.

These are the no-fuss cookies to keep in your back pocket when you forget about the kids' school holiday party or that cookie swap you committed to weeks ago. They're lightly scented with orange zest and studded with white chocolate chips and dried cranberries.

Imagine the flavors of fire-roasted s'mores packed into a bar that includes a chewy cookie-like graham cracker crust and the golden-crisp exterior of a fresh-roasted marshmallow — all in one tidy bar that you can eat anywhere.

What makes this no-bake, double-layered treat of brown butter- and marshmallow-coated oats so special is the streak of salted chocolate through the center. And they're just as easy to make as Rice Krispies treats.

These nutty, buttery bars are just like classic, jam-filled linzer cookies, but they're so much easier to make.

No matter what name you know these bars by, one thing is certain: These sweet bars are absolutely amazing. A slew of pantry ingredients are layered together for a chocolatey, nutty bar that's part cookie and part candy.

These bars are sweet nostalgia through and through. There's a double dose of peanut butter in the base and topping, with a layer of your favorite jam sandwiched in the center.

As far as bar cookies go, this recipe just might be the ultimate win. The shortbread bottom is buttery and rich, and just the right balance for the toffee and chocolate.

If this time of year makes you swoon over all things cranberry, these bars will be right up your alley. They're inspired by classic lemon bars, and have a sweet-tart bite that is nothing but delicious.

With a chewy cookie on the bottom, marshmallow-like meringue on top, and a rich layer of chocolate sandwiched in between, these bar cookies were created with sweet tooths in mind.
