Essential Reese’s Cookie Bar Ingredients

Crafting the perfect batch of Reese’s Cookie Bars starts with high-quality ingredients, each playing a crucial role in achieving that sought-after chewy texture and rich flavor profile:

Butter: For a truly rich and buttery base, you’ll need 1 cup (or two sticks) of unsalted butter, softened to room temperature. Room temperature butter creams beautifully with sugar, incorporating air for a lighter, more tender crumb.

Granulated Sugar: Adding ¾ cup of granulated sugar helps achieve that perfect balance of sweetness and contributes significantly to the chewy texture we love in a good cookie bar. It also aids in spreading during baking.

Brown Sugar: A full 1 cup of packed light or dark brown sugar is key. Brown sugar adds moisture, depth of flavor, and a wonderful caramel-like note, making the bars incredibly soft and chewy.

Eggs: Two large eggs act as a binder, bringing all the ingredients together, adding richness, and contributing to the structure and moisture of the cookie bars. Ensure they are also at room temperature for better emulsification.

Vanilla Extract: To enhance the overall delicious flavors in this dough, incorporate 1 teaspoon of high-quality vanilla extract. Vanilla is a flavor enhancer that brings out the best in both the cookie and the candies.

All-Purpose Flour: The fundamental structure of these delightful cookie bars comes from 3 cups of all-purpose flour. Make sure to measure it correctly by spooning it into the measuring cup and leveling it off, rather than scooping directly from the bag, which can lead to too much flour.

Salt: A crucial ¾ teaspoon of salt is added to balance the sweetness of the sugars and the candies, bringing out all the complex flavors and preventing the bars from tasting overly sweet.

Baking Soda: For that perfect lift and tender texture, ¾ teaspoon of baking soda is essential. It reacts with the acidic brown sugar to help the cookie bars rise beautifully and become light and airy as they bake.

Reese’s Pieces: The star of the show! You’ll need 2 cups of Reese’s Pieces candies for their signature peanut butter flavor and satisfying crunch. Feel free to use either the standard size or the mini candies, depending on your preference for smaller or larger bursts of candy goodness.

How to Prepare Reese’s Pieces Cookie Bars: A Step-by-Step Guide

Making these decadent Reese’s Cookie Bars is incredibly straightforward. Follow these simple steps for a perfect batch every time:

Preparation Phase

Start by preheating your oven to 350°F (175°C). While the oven heats, take a 9×13 inch baking pan and thoroughly spray it with a non-stick cooking spray. This crucial step ensures your bars won’t stick and will release easily once cooled. Set the prepared pan aside, ready for the dough.

Crafting the Cookie Dough

In a large mixing bowl, combine the softened butter, granulated sugar, brown sugar, eggs, and vanilla extract. Using an electric mixer (handheld or stand mixer), cream these wet ingredients together until they are light, fluffy, and well combined. This usually takes about 2-3 minutes, and you should see the mixture lighten in color.

In a separate, smaller bowl, whisk together the dry ingredients: all-purpose flour, salt, and baking soda. Sifting these ingredients ensures they are evenly distributed and prevents lumps in your dough, leading to a perfectly consistent texture.

Gradually add the dry ingredient mixture to the wet butter and sugar mixture. Mix on low speed, or stir by hand, until just combined. Be careful not to overmix the dough once the flour is added, as this can develop the gluten too much, resulting in tougher bars. Stop mixing as soon as no white streaks of flour are visible.

Finally, gently fold in the 2 cups of Reese’s Pieces candies. Use a spatula to carefully incorporate them throughout the dough, ensuring they are evenly distributed in every delicious bite.

Baking to Golden Perfection

Once the dough is ready, press it evenly into the greased 9×13 inch pan. You can use your hands or the back of a spoon to ensure an even layer from edge to edge. An even thickness will help the bars bake uniformly.

Place the pan into your preheated oven and bake for 18-20 minutes. The bars are done when they appear puffy, the edges are lightly golden brown, and the center is set and no longer glossy. Avoid overbaking, as this can lead to dry bars. The residual heat from the pan will continue to cook them slightly even after they’re removed from the oven.

The most important step for perfectly structured bars: allow the cookie bars to cool completely in the pan before attempting to cut them. This allows them to firm up, making them much easier to slice into neat bars without crumbling. Patience is key for this step!

Once cooled and cut, serve these delightful Reese’s Cookie Bars and enjoy the cheers from happy faces!

Can I Freeze Peanut Butter Cookie Bars for Later?

Absolutely! These peanut butter cookie bars are an excellent candidate for freezing, making them ideal for meal prep or ensuring you always have a sweet treat on hand. You have two convenient options: freezing them after they’ve been baked and cooled, or freezing the prepared cookie dough.

If you opt to freeze baked cookie bars, ensure they are completely cooled before wrapping them tightly in plastic wrap, then placing them in an airtight container or heavy-duty ziplocked freezer bag. This double layer of protection helps prevent freezer burn and keeps them as fresh as possible. For best results, place parchment paper between individual bars to prevent sticking.

For freezing the cookie dough, you can press it into the prepared 9×13 inch pan, cover it tightly with plastic wrap and then foil, and freeze. When you’re ready to bake, you can either let the dough thaw in the refrigerator overnight or bake it directly from frozen, adding a few extra minutes to the baking time. Both the baked cookies and the raw dough will maintain their quality for up to 3 months when stored properly in the freezer. Simply thaw frozen baked bars on the counter or warm briefly in the microwave for a fresh-baked taste.

How Long Do These Delicious Cookie Bars Stay Fresh?

When stored correctly, these delightful Reese’s Cookie Bars will remain fresh and delicious for 3 to 5 days at room temperature. To ensure your treats stay as fresh and soft as possible, always keep them in an airtight container or a securely sealed ziplocked bag. This prevents them from drying out and maintains their wonderful chewy texture.

Here’s a clever trick I’ve learned over the years to keep cookies and bars extra fresh and soft: simply place a slice of plain bread (any type will do, but a softer white bread works best) into the airtight container along with your cooled cookie bars. The bread helps by transferring its moisture to the cookies, which prevents them from hardening. You’ll be amazed at how this simple trick keeps your bars wonderfully soft and chewy for a couple of extra days! Just remember to replace the bread slice every day or two if it becomes hard.

Selecting the Perfect Vanilla Extract

The quality of your vanilla extract can significantly impact the overall flavor of your baked goods. A few years ago, I conducted an extensive taste test of 10 different vanilla extracts, and I discovered some new favorites that I wholeheartedly recommend!

For everyday baking, I absolutely love using TOTONAC’s Mexican Vanilla. It’s a pure vanilla extract and, importantly, contains no alcohol. I personally prefer the taste of alcohol-free extracts, as I find they offer a cleaner, more authentic vanilla flavor without any harsh undertones. Every time I experiment with another brand, I quickly find myself returning to Totonac’s; it’s simply that good! Its rich, creamy profile enhances any dessert.

Another fantastic option I adore, especially when I want to see those beautiful vanilla specks in my treats, is Nielsen Massey Vanilla Bean Paste. This paste offers an unparalleled depth of flavor and a lovely visual appeal that truly takes your baking to the next level. If you can find it, it’s definitely worth the investment for its superior taste and aroma.

Tips for Baking Perfect Reese’s Cookie Bars Every Time

Achieving bakery-quality cookie bars at home is easier than you think with a few simple tips:

• Room Temperature Ingredients: Ensure your butter and eggs are at room temperature. This allows them to cream together more effectively, creating a smoother, more emulsified dough that results in a tender, even crumb.
• Measure Flour Correctly: For accurate results, spoon your flour into the measuring cup and level it off with a straight edge, rather than scooping directly from the bag. Too much flour can lead to dry, dense bars.
• Do Not Overmix: Once you’ve added the dry ingredients to the wet, mix only until just combined. Overmixing develops the gluten in the flour, which can make your cookie bars tough instead of wonderfully chewy.
• Evenly Press the Dough: When pressing the dough into the pan, make sure it’s spread in an even layer. This ensures uniform baking, so all parts of the bar cook at the same rate and come out perfectly.
• Don’t Overbake: Keep a close eye on your oven! Cookie bars can go from perfectly golden to overdone very quickly. Look for lightly golden edges and a center that is set but still slightly soft. They will continue to cook slightly as they cool.
• Cool Completely: This is arguably the most important tip for cutting neat bars. If you try to slice them while warm, they will likely crumble and be messy. Patience is key – let them cool completely in the pan before cutting.

Delightful Variations for Your Reese’s Cookie Bars

While the classic Reese’s Cookie Bar is perfect as is, you can easily customize this recipe to suit your preferences or what you have on hand:

• Mixed Candies: Instead of just Reese’s Pieces, try a combination of Reese’s Pieces and mini Reese’s Peanut Butter Cups, or even chocolate chips and M&M’s for a truly colorful and varied treat.
• Nutty Additions: Enhance the peanut butter flavor with a sprinkle of chopped roasted peanuts or other nuts like pecans or walnuts folded into the dough.
• Chocolate Drizzle: Once the bars are cooled, melt some chocolate chips (milk, dark, or white) and drizzle artfully over the top for an extra layer of sweetness and visual appeal.
• Swirl of Peanut Butter: Before baking, dollop spoonfuls of extra peanut butter onto the surface of the dough and swirl it gently with a knife for an even more intense peanut butter experience.
• Flaky Sea Salt: A sprinkle of flaky sea salt over the top of the warm bars after they come out of the oven can beautifully enhance the sweet and savory notes.
