Peanut Butter Bars Recipe

Peanut Butter Bars

History of Peanut Butter Bars

Peanut butter bars, a quintessential American treat, have been around for decades, delighting generations with their perfect blend of peanut butter and chocolate. While their exact origins are unclear, they gained popularity in the mid-20th century, often served as a simple yet indulgent dessert in households across the U.S. Combining pantry staples like graham crackers, peanut butter, and chocolate, they provide a no-bake, easy-to-make solution for satisfying sweet cravings. These bars are a modern twist on the classic peanut butter cup, which has roots going back to the 1920s with the invention of Reese's Peanut Butter Cups by Harry Burnett Reese.

Regional Variations

Though this treat is loved across the U.S., different regions have adapted the basic recipe to suit local tastes. In some areas, such as the Midwest, peanut butter bars are a popular offering at community potlucks and bake sales. In the South, variations often include additional ingredients like coconut or pecans, lending a regional flair to the simple bar. While some prefer their bars thicker or with a crunchier texture, others opt for a smoother, melt-in-your-mouth version that mirrors the texture of a peanut butter cup.

What Makes Peanut Butter Bars Unique?

While peanut butter bars may seem similar to other chocolate-peanut butter desserts, such as peanut butter cups or no-bake peanut butter cookies, they stand apart due to their balanced layering. Unlike traditional peanut butter cups, which feature a distinct chocolate coating, peanut butter bars incorporate a smooth, rich chocolate layer that covers the peanut butter base evenly. The use of graham crackers in the base also gives these bars a satisfying texture, unlike other desserts that might rely on cookies or cake for structure. Furthermore, the peanut butter filling in the bars is often smoother, making it easier to cut and serve than more crumbly peanut butter cookies.

Where Are Peanut Butter Bars Typically Served?

Peanut butter bars are a staple at family gatherings, bake sales, and parties, thanks to their simplicity and crowd-pleasing flavor. They are also commonly made for holidays like Christmas and Thanksgiving, often found in dessert tables alongside cookies and other sweet treats. Because of their ease of preparation, they are frequently prepared for last-minute events and potlucks, where they can be sliced and shared with minimal effort. In fact, their no-bake nature makes them an ideal choice for summer gatherings when turning on the oven is less appealing.

Interesting Facts About Peanut Butter Bars

  • The first commercially successful peanut butter cup, a precursor to the peanut butter bar, was created by H.B. Reese in 1928.
  • Many recipes for peanut butter bars call for minimal ingredients, making them one of the easiest desserts to prepare, often requiring just five to six items.
  • While they are often associated with the United States, variations of chocolate and peanut butter desserts exist in other countries, such as in the UK, where similar "biscuits" are enjoyed.
  • Peanut butter bars are incredibly versatile and can be adapted for different dietary preferences, such as using gluten-free graham crackers or vegan substitutes for butter and chocolate.
  • In recent years, many people have experimented with adding extra flavor to the bars, such as a dash of sea salt or even a hint of spice, to enhance the flavor profile.

FAQ about Peanut Butter Bars Recipe

Yes, you can substitute the graham cracker crumbs with crushed digestive biscuits or vanilla wafer crumbs. For the peanut butter, you can use natural peanut butter, but it may result in a slightly softer texture. You can also use milk or dark chocolate chips instead of semi-sweet chips depending on your preference.

To make the bars less sweet, you can reduce the amount of confectioners' sugar or use a sugar substitute. You could also opt for dark chocolate chips instead of semi-sweet or milk chocolate chips, as they are less sweet.

Absolutely delicious! If you're a fan of peanut butter and chocolate like me, this recipe is a must-try. I took the advice of other reviewers and simplified the process by melting the peanut butter with butter, then combining it with graham crackers and powdered sugar. Don't forget to chill the peanut butter base for 15 minutes before adding the chocolate topping - it makes a world of difference!

I made some adjustments to the recipe by reducing the butter to 1 1/2 sticks and using 14 graham crackers along with milk chocolate chips. Instead of melted butter, I opted for softened butter. It's important to finely pulverize the graham crackers to achieve the right texture (a food processor does the trick perfectly). I baked them in a 7x11 pan for a thicker result. The bars taste very similar to Reese's, although the filling is slightly coarser. Make sure to store them in the refrigerator to avoid ending up with a soft, gooey mess!

This recipe stands out among all the chocolate/peanut butter bar recipes on this site as the best in my opinion. The ratio of chocolate layer to peanut butter layer is just right, and it's not overly sweet, allowing the distinct flavors of chocolate and peanut butter to shine through. I made a few tweaks to suit my personal taste – I added an extra 1/2 cup of peanut butter to the bottom layer mixture, used Hershey's Special Dark chocolate chips instead of semi-sweet chips, and used the entire 12 oz bag (equivalent to 2 cups). With more chips on hand, I also incorporated 1/4 cup of butter into the chocolate/peanut butter melting mixture to ensure a smooth and easily spreadable chocolate layer that adheres well to the peanut butter layer.

These bars have quickly become a must-have in my household! It's my go-to recipe whenever I need to bring a sweet treat to any event. They are incredibly easy and quick to make, perfect for those times when I need to satisfy my cravings in a hurry. I always chill the peanut butter base for 15-20 minutes before adding the chocolate topping to prevent the warm chocolate from melting too much into the peanut butter. This ensures a perfect balance of chocolate and peanut butter in every bite!

I found these treats to be delicious and quite sweet. I initially made them to gift to a friend, but they didn't hold up as well as I had expected. Sadly, I'll be keeping this batch for myself. However, I plan to adjust the recipe by using less butter in the peanut butter mixture, reducing the amount of peanut butter in the chocolate, and adding a touch of salt for the next batch intended for my friend. Nonetheless, thank you for sharing the recipe!

I have to say, this candy recipe is hands down the best I've ever made. It's incredibly delicious and a breeze to whip up. I stuck to the recipe to a tee, letting the peanut butter base chill in the fridge for 30 minutes before adding the chocolate topping. After letting it set for a couple of hours, I sliced it up, and it was absolutely perfect. Honestly, I wouldn't change a single thing about it. I highly recommend following the recipe as is before considering any tweaks, as I can't imagine wanting to alter it in any way. It truly captures the flavor of a Reese's Peanut Butter Cup.

I've been making these bars for years, and I call them Stompers Delights, inspired by a recipe in Vogue. I prefer to mix the ingredients by hand instead of using a mixer, as I find it easier to control the texture that way. I take special care to smooth out the peanut butter, graham cracker, and 10X sugar mixture to ensure it's evenly spread, especially around the edges and corners. I often use a small fondant rolling pin for this. Once I pour on the chocolate, I let the bars cool at room temperature for easier cutting, though you can refrigerate them if you prefer - just keep an eye on the chocolate so it doesn't become too hard to cut. Sometimes I like to drizzle melted peanut butter chips on top for a decorative touch before slicing. And occasionally, I opt for chunky peanut butter instead of smooth to add extra texture.

I absolutely adore this recipe that reminds me of my grandmother's baking. I made a few tweaks by adding 1/2 cup of powdered sugar for a firmer texture, using butter-flavored Crisco just like she did, and incorporating 1/2 cup of peanut butter for a delicious twist. After chilling the crust for 10 minutes, I rolled it into balls, chilled them again, dipped them in chocolate, placed them on wax paper, and then chilled them once more. The result was pure perfection!

This recipe is fantastic! I followed the instructions exactly but used mini muffin tins with mini liners to create a Reese's peanut butter cup-like treat. Halving the recipe yielded 24 cups, and they easily came out of the liners. I added a sprinkle of Maldon finishing salt before refrigerating, and it was the perfect touch. My family absolutely adores these treats!

I have followed this recipe multiple times exactly as written and it always turns out delicious. Recently, I decided to make a small tweak and it worked out wonderfully, so I wanted to share my experience. In an effort to incorporate more flax seed and other fibers into my diet, I substituted 1/2 cup of crushed graham crackers with 1/2 cup of ground flax seed (which, to me, tastes like unsweetened graham crackers). After mixing the melted butter with the graham/flax mixture, I let it sit for about 20 minutes until the butter had cooled down. This allowed it to soak into and soften the flax seed and graham crackers before adding the remaining ingredients. The result? I couldn't even tell the difference! Adding ground flax seed is a great way to increase the fiber content of this already indulgent recipe without compromising on taste. The bars in the picture have been refrigerated due to the high temperatures here, but they maintain the original recipe's taste and texture. As someone with sensory sensitivities, I can assure you that I wouldn't enjoy it if that weren't the case. I highly recommend giving this modification a try.

Rewritten review: I would rate this recipe as 3 stars as is. Following the advice of other reviewers, I decided to melt the butter and peanut butter together, which worked well. I found that using only half a cup of butter was sufficient. Cutting the bars after 10-15 minutes in the refrigerator, as recommended by other reviewers, was definitely the right call; waiting an hour would have been a mistake. I suggest using a stoneware pan instead of a non-stick one for easier cutting with a paring knife. For a more authentic Reese's PB flavor, I swapped in milk chocolate chips instead of semi-sweet and also mixed in some leftover Reese's chips melted with the chocolate chips instead of using extra peanut butter.

I really enjoy this recipe because I'm a big fan of the chocolate and peanut butter combination. The only improvement I would suggest is to include specific instructions on how long to melt the chocolate chips and peanut butter together.

These cookies turned out perfectly! We had all the ingredients on hand which was a bonus. I made two substitutions: used dark chocolate chunks instead of semi-sweet chips and natural peanut butter. These tweaks resulted in cookies that were just the right level of sweetness, not too overpowering.

I added 1 tablespoon of icing sugar and slightly less than 1/2 cup of butter to the peanut butter layer when I made it for my dad. It turned out amazing! My sister even said it tasted just like a Reese's peanut butter cup!

I tried making these bars using organic natural peanut butter, but it turned out a bit too runny, so I ended up adding more graham crackers. Next time, I think I'll make a 1.5 batch to achieve the thicker consistency like in the pictures and videos, or I might use a 9x9 square pan for a single batch. Overall, the process was quick, not messy, and cleanup was easy.
