Essential Ingredients for These Holiday Cookie Bars
For precise measurements and detailed instructions, kindly refer to the printable recipe card located at the bottom of this article.
Crafting these delectable Dark Chocolate Chip Peppermint Cookie Bars requires a handful of simple, high-quality ingredients, most of which you likely already have in your pantry. Each component plays a vital role in achieving that perfect balance of chewy, chocolatey, and minty goodness.
- Pantry Staples: You’ll need standard all-purpose flour for the structure, a touch of salt to balance the sweetness, baking soda for a perfect rise and chewy texture, and a combination of granulated sugar and light brown sugar for depth of flavor and moisture.
- Flavoring Extracts: Pure vanilla extract is crucial for a warm, classic cookie flavor, while peppermint extract provides that signature cool, festive kick. Be sure to use high-quality extracts for the best taste.
- Eggs: Large, room-temperature eggs act as a binder, contributing to the bars’ rich texture and structure.
- Unsalted Butter: Softened unsalted butter is key for achieving a tender, flavorful dough. Using unsalted butter gives you control over the overall saltiness of the recipe.
- Dark Chocolate Chips: These are the star of the show, providing a rich, slightly bitter contrast to the sweet cookie base and peppermint. A 10-ounce bag (approximately 1 ¾ cups) is usually sufficient. Feel free to substitute with semi-sweet, milk chocolate, or even white chocolate chips based on your preference.
- Crushed Peppermint Candy: This ingredient adds both a burst of refreshing flavor and a delightful crunch. You can often find pre-crushed peppermint candy in bags near the chocolate chips or holiday baking supplies at your local grocery store during the holidays. If not, they are also readily available on Amazon, or you can easily crush your own candy canes (see FAQ section for tips!).
Baking Your Own Dark Chocolate Chip Peppermint Cookie Bars
For the complete, step-by-step recipe, please refer to the detailed instructions in the recipe card at the bottom of this page.
Creating these festive cookie bars is a straightforward and rewarding process. Here’s a quick overview of the essential steps:
- Prepare Your Pan: Begin by preheating your oven to 350° F (175° C). Crucially, line a 9×13 inch baking pan with parchment paper, ensuring you leave a generous overhang on all sides. This simple trick will make lifting the cooled bars out of the pan incredibly easy, preventing sticking and ensuring clean cuts. Set your prepared pan aside.
- Craft the Cookie Dough: In a large bowl, you’ll first cream together the softened butter and both sugars until light and fluffy. Next, incorporate the eggs and both vanilla and peppermint extracts until thoroughly blended. In a separate bowl, whisk together your dry ingredients (flour, salt, baking soda). Gradually add the dry mixture to the wet ingredients, mixing until just combined. Finally, fold in those beautiful dark chocolate chips and crushed peppermint candy until they are evenly distributed throughout the rich dough. Using your hands can sometimes be the easiest way to ensure an even mix.
- Bake to Perfection: Gently transfer the prepared cookie dough into your parchment-lined pan. Press it into an even layer using your hands or a spatula. For an extra touch of visual appeal, you can press a few additional chocolate chips and peppermint pieces onto the top of the dough before baking. Bake for the recommended time (typically 20-22 minutes), or until the edges are lightly golden and a toothpick inserted into the center comes out with only moist crumbs.
- Cool and Slice: Once baked, allow the cookie bars to cool completely in the pan on a wire rack. This is a critical step for perfect texture and clean cuts. Once fully cooled, use the parchment paper overhang to lift the entire slab of cookie bars onto a cutting board. Then, slice them into your desired squares or bars.

Proper Storage for Freshness
To keep your delicious **Dark Chocolate Chip Peppermint Cookie Bars** fresh and flavorful for as long as possible, store them in an airtight container at room temperature. They will maintain their quality for up to one week. Choose a cool, dry spot away from direct sunlight to prevent them from drying out or melting. If you live in a particularly hot or humid climate, it’s advisable to store your cookie bars in the refrigerator to preserve their texture and prevent the chocolate from becoming too soft.
For longer storage, these cookie bars freeze exceptionally well. Once completely cooled and sliced, arrange them in a single layer on a baking sheet and freeze for about an hour until firm. Then, transfer the frozen bars to an airtight freezer-safe container or a heavy-duty freezer bag, separating layers with parchment paper to prevent sticking. They can be frozen for up to 2-3 months. Thaw them at room temperature or gently warm them for a few seconds in the microwave for a fresh-baked taste.
Expert Recipe Tips for Perfect Cookie Bars
Achieving bakery-quality **Dark Chocolate Chip Peppermint Cookie Bars** is easy with these helpful tips:
Bake on the Middle Rack: For optimal and even baking, always place your cookie bar pan on the middle rack of your oven. This ensures that the heat circulates properly around the pan, preventing over-browning on the bottom or under-baking in the center.
Use Softened Real Butter: Do not substitute butter for margarine in this recipe; real butter provides superior flavor and texture. Furthermore, ensure your unsalted butter is properly softened to room temperature. It should be cool to the touch but yield easily when you gently press it with your finger. This allows it to cream effectively with the sugars, creating a light and airy dough that results in chewy bars.
Crushed Peppermint Candy: For convenience, I recommend buying bags of pre-crushed peppermint candy, which are typically found near the chocolate chips or in the holiday baking section of most grocery stores during the festive season. If you can’t find them, they are also available online. Alternatively, crushing your own candy canes is simple (refer to the FAQ section for detailed instructions).
Chill for Clean Cuts: To achieve beautifully crisp and clean edges on your cookie bar squares, it’s highly recommended to chill the entire pan of baked cookie bars in the refrigerator for at least 30 minutes (or even longer) before attempting to cut them. Cold chocolate peppermint cookie bars will slice much more cleanly and easily than bars that are still warm or at room temperature, preventing crumbling and smudging.
Parchment Paper is Key: Always line your baking pan with parchment paper, leaving an overhang on the sides. This ensures that the bars don’t stick to the pan and allows you to easily lift the entire cooled slab out for effortless cutting. Never use wax paper for baking, as it is not heat-safe and can catch fire in the oven.

Frequently Asked Questions About Dark Chocolate Chip Peppermint Cookie Bars
Here are answers to some common questions you might have while baking these delightful holiday treats:
How do you know when cookie bars are perfectly baked?
Your cookie bars are ready when the edges are lightly golden brown, and the center appears set but still slightly soft. The best way to check for doneness is to insert a clean toothpick into the very middle of the pan. If the toothpick comes out with only a few moist crumbs clinging to it, they are done. Avoid overbaking, as this will result in dry, crumbly bars instead of the desired soft and chewy texture. If the toothpick is covered in wet batter, the bars need a few more minutes in the oven.
Can I prepare the cookie bar dough in advance?
Absolutely! Preparing the cookie dough ahead of time is a fantastic way to streamline your holiday baking. You can store the unbaked cookie dough in the refrigerator, tightly covered with plastic wrap, for up to three days. When you’re ready to bake, allow the dough to come to room temperature for about 20-30 minutes before pressing it into the pan and baking as directed. This makes it a great option for busy schedules.
Is it necessary to chill the cookie bar dough before baking?
For this specific recipe, chilling the dough before baking isn’t strictly necessary; you can bake it right away. However, chilling cookie dough is almost always a good idea if you have the time. It allows the flavors to meld and deepen, resulting in a richer taste. More importantly, chilling solidifies the fats in the butter, which helps prevent the cookies from spreading too much in the oven, leading to thicker, chewier bars with a more defined texture. If you desire a slightly thicker bar, a 30-minute chill can work wonders.

What’s the best way to cut bar cookies cleanly?
Achieving perfectly neat and tidy cookie bar squares or rectangles is simpler than you think with these professional tips:
- Parchment Paper is Your Friend: Always start by lining your baking pan with parchment paper, leaving an overhang on all sides. This allows you to easily lift the entire cooled slab of cookie bars out of the pan, making cutting much simpler and mess-free.
- Chill Thoroughly: As mentioned in our tips, chilling the pan of baked cookie bars for at least 30 minutes (or up to a couple of hours) in the refrigerator is crucial. Cold chocolate peppermint cookie bars will cut significantly more cleanly and precisely than bars that are still warm or at room temperature. The chocolate will be firm, preventing smears.
- Use a Warm, Clean Knife: Once chilled, remove the uncut bars from the pan using the parchment overhang and place them on a sturdy cutting board. For the cleanest cuts, run a sharp, long knife under very hot water, then carefully wipe it completely dry. The warm blade will glide through the chocolate and cookie dough more smoothly.
- Measure and Trim: Use a ruler as a guide for consistent sizes. For truly pristine edges on all of your cookie bars, you might consider trimming off the very edges that were against the sides of the pan. This is optional but yields a professional look.
- Wipe Between Cuts: You may need to wipe the knife clean between each cut, and reheat it under hot water as needed, especially if the chocolate starts to stick. This ensures every bar is as perfect as the last.
How many servings can I get from a 9×13 inch pan?
The number of servings depends on your desired bar size. A standard 9×13 inch pan is quite versatile:
- For 12 generous servings: Cut the short side of the pan into three equal parts, then cut the long side into four equal parts. This will result in fairly large, satisfying chocolate chip cookie bars.
- For 15 standard servings: Cut the short side into three equal parts, and the long side into five equal parts. This yields a more standard-sized serving, perfect for most occasions.
- For 20 smaller servings: To get the most servings from your 9×13 pan, cut the short side into four equal parts and the long side into five equal parts. This is ideal for parties or when you want smaller portions.
Using a ruler as a guide will help ensure all your cuts are even and your bars are uniform.

What type of chocolate chips work best?
While the recipe calls for dark chocolate chips to complement the sweetness of the peppermint, the choice is ultimately yours! You can absolutely experiment with other varieties. Milk chocolate chips will yield a sweeter, creamier bar, while semi-sweet provides a classic balance. For a fun twist, consider white chocolate chips, which would offer a beautiful visual contrast and a different flavor profile. Whatever your preference, these cookie bars are incredibly adaptable and delicious with any kind of chocolate chip.
What’s the best method for crushing candy canes?
If you can’t find pre-crushed peppermint candy, crushing your own candy canes is easy and quite satisfying! My favorite method is to place them in a sturdy Ziploc bag, remove as much air as possible, and then use the flat side of a meat tenderizer to smash them. You can also achieve excellent results with a rolling pin or even a small hammer. The key is to take your time and aim for pieces that are about the size of “pop rocks” – visible enough to provide texture, but small enough to chew comfortably without any sharp edges. Avoid crushing them into a fine powder; you want those delightful little crunchy bits!
