Ingredients for Your Decadent Reese’s Chocolate Chip Cookie Bars

Crafting these magnificent cookie bars requires just a handful of readily available ingredients, many of which you likely already have in your pantry. The beauty of this recipe lies in its simplicity and the clever use of a yellow cake mix as the foundation for a soft, chewy, and flavorful bar. Here’s a detailed look at what you’ll need:

• 1 box Yellow Cake Mix: This is the superstar ingredient that makes these bars incredibly easy and ensures a consistently moist and tender crumb. A standard 15.25 oz box, like Pillsbury, works perfectly. It provides the flour, sugar, and leavening all in one go.
• Large Eggs: Eggs bind the ingredients together, add moisture, and contribute to the rich texture of the cookie bars. We recommend using two large eggs for optimal results.
• Pure Vanilla Extract: A teaspoon of good quality vanilla extract enhances all the other flavors, adding a warm, aromatic depth that is essential in any sweet baked good.
• Melted Butter: Instead of oil, using melted butter gives these bars a wonderfully rich, buttery flavor and a tender chewiness that oil simply can’t replicate. Make sure it’s fully melted but not boiling hot before adding to the mix.
• Almond Milk (or alternative): Just two tablespoons of liquid help bring the dough to the right consistency. While almond milk is a great choice for its subtle flavor, feel free to use regular milk, heavy cream for extra richness, or even water if that’s all you have on hand.
• Salt: A quarter teaspoon of salt is crucial for balancing the sweetness and enhancing the overall flavor profile of the cookie bars. Don’t skip it, as it truly makes a difference.
• Milk Chocolate Chips: These provide classic, melt-in-your-mouth chocolate goodness. If you prefer a slightly less sweet bar, you can easily substitute with semi-sweet chocolate chips. Use a full cup for plenty of chocolate in every bite.
• Peanut Butter Chips: For an extra boost of peanut butter flavor and a delightful textural contrast, peanut butter chips are a must. A quarter cup is enough to distribute that creamy, nutty taste throughout.
• Mini Reese’s Peanut Butter Cups: The star attraction! These add an explosion of Reese’s flavor and a charming visual appeal. One cup of mini cups, chopped if desired, ensures a generous distribution of that beloved chocolate-peanut butter combination. You can also use other peanut butter cups of your choice, just chop them into smaller pieces.

How to Bake Your Easy Reese’s Chocolate Chip Cake Mix Cookie Bars

Getting these incredible cookie bars from concept to creation is surprisingly straightforward. Follow these simple steps for a perfect batch every time:

1. Prepare Your Baking Pan: Begin by selecting either an 8×8 inch or a 9×9 inch baking pan. For thicker, chewier bars (as pictured and highly recommended!), opt for the 8×8 inch pan. If you prefer slightly thinner bars, the 9×9 inch pan will work well. Lightly spray the entire inside of your chosen pan with a nonstick cooking spray to prevent sticking and ensure easy removal.
2. Combine the Wet and Dry Ingredients: In a large mixing bowl, combine the yellow cake mix, salt, eggs, vanilla extract, almond milk (or your chosen liquid), and melted butter. You can use an electric mixer on low speed or mix by hand with a sturdy spoon until all ingredients are just combined and a soft dough forms. Be careful not to overmix, as this can lead to tougher bars.
3. Fold in the Goodies: Gently fold in the milk chocolate chips, peanut butter chips, and mini Reese’s peanut butter cups into the dough. Distribute them evenly throughout the mixture to ensure every bite is packed with flavor.
4. Press into the Pan: The dough will be quite sticky, which is perfectly normal. To spread it evenly into the prepared pan, you have a couple of options:
   • Use an angled spatula that has been lightly sprayed with non-stick spray. This will help the dough release easily from the spatula.
   • Alternatively, lightly spray your hands with non-stick spray and gently press the dough into the pan. This method allows for good control and even distribution.

   Press the dough out to an even layer across the bottom of the pan.

5. Add Toppings (Optional but Recommended): For an even more visually appealing and flavor-packed top, barely press a few extra chocolate chips and mini Reese’s cups onto the surface of the dough. It’s important not to push them deep into the batter, as the bars will rise during baking, and you want these toppings to remain visible and slightly crisp on top.
6. Bake to Golden Perfection: Preheat your oven to 350°F (175°C). Bake the cookie bars for 25-30 minutes, or until the edges are lightly golden brown and a toothpick inserted into the center comes out with moist crumbs (not wet batter). The center may look slightly soft, but it will firm up as it cools.
7. Cool Completely: This step is crucial for perfectly structured bars. Remove the pan from the oven and allow the bars to cool completely on a wire cooling rack before attempting to cut them. Cutting them while warm will result in crumbly, messy bars. Patience is key here, but it will be worth it!

Pro Baking Tips for Flawless Cookie Bars

Achieving bakery-quality cookie bars at home is easier than you think, especially with a few expert tips up your sleeve. These simple techniques can elevate your baking experience and ensure your Reese’s Chocolate Chip Cookie Bars turn out perfectly every time:

• The Parchment Paper Liner Trick: For a truly mess-free experience and effortless removal, line your baking pan with parchment paper or aluminum foil before spraying with non-stick spray. Allow the paper or foil to extend over the sides of the pan, creating “handles.” Once the bars are completely cooled, you can simply lift them out of the pan onto a cutting board. This method is a game-changer for brownies and bars, making clean-up a breeze and preventing any sticking.
• Don’t Overbake: It’s tempting to bake until the bars look fully firm, but remember that bars continue to cook slightly even after they’re removed from the oven. Aim for a light golden-brown edge and a center that looks just set. Overbaking can lead to dry, crumbly bars instead of the desirable soft and chewy texture.
• Cooling is Crucial: As mentioned in the instructions, allowing the bars to cool completely on a wire rack is non-negotiable. This process allows them to set properly, making them much easier to cut into clean, neat squares. If you try to cut them while warm, they’ll be gooey and fall apart.
• Sharp Knife for Clean Cuts: Once cooled, use a sharp, non-serrated knife to cut your bars. For extra clean cuts, you can wipe the knife blade clean between each cut, especially if the chocolate or peanut butter chips are sticky.
• Room Temperature Ingredients: While this recipe uses melted butter, generally for baking, ensuring ingredients like eggs are at room temperature helps them incorporate more smoothly into the batter, leading to a more uniform texture.

Creative Cake Mix Bar Add-In Variations

One of the best aspects of this cake mix cookie bar recipe is its incredible versatility. While the Reese’s chocolate chip combination is a classic for a reason, you can easily customize these bars to suit your mood, available ingredients, or the occasion.

• Explore Other Peanut Butter Cup Varieties: Don’t limit yourself to just mini Reese’s cups! There’s a whole world of peanut butter cups out there. You might explore The Best Peanut Butter Cups You Can Buy, According to Candy Fanatics. Chop up dark chocolate peanut butter cups for a richer flavor, white chocolate peanut butter cups for a creamier twist, or even seasonal varieties for a festive touch.
• Utilize Leftover Holiday Candies: Holidays often leave us with an abundance of various candy bars. This recipe is an excellent way to use them up! Simply chop any leftover candy bars – Snickers, Twix, M&M’s, Butterfingers, etc. – into chunks and fold them into the dough. Each bite will be a delightful surprise.
• Mix and Match Chocolate Chips: While milk chocolate chips are fantastic, feel free to experiment with other types of chocolate chips. Dark chocolate chips will add a sophisticated bitterness, white chocolate chips will bring a creamy sweetness, and even butterscotch or caramel chips could be interesting additions.
• Embrace the Sprinkles: Who doesn’t love sprinkles? Stir them into the batter for a festive pop of color, or generously scatter them over the top before baking for a truly celebratory look. They’re especially great for birthdays or holiday themes!
• Add Nuts or Pretzels: For an extra layer of texture and flavor, consider folding in chopped walnuts, pecans, or even crushed pretzels. Nuts add a delightful crunch and earthy flavor, while pretzels introduce a salty-sweet dimension that perfectly complements the chocolate and peanut butter.
• Swirls of Goodness: After spreading half the dough into the pan, dollop spoonfuls of peanut butter, Nutella, or even marshmallow fluff on top. Then, cover with the remaining dough and gently swirl with a knife for beautiful ribbons of flavor throughout your bars.
