The History of Chocolate and Peanut Butter Pairing
The pairing of chocolate and peanut butter is a timeless classic that has roots in American candy-making traditions. While the exact origin of the combination is difficult to pinpoint, it is widely believed that the marriage of chocolate and peanut butter became popular in the early 20th century. One of the earliest commercial products to feature this pairing was the Reese’s Peanut Butter Cup, introduced in 1928 by Harry Burnett Reese. Reese’s success with the candy led to the widespread recognition of chocolate and peanut butter as a complementary flavor duo. Over time, this combination became a staple in desserts, from cookies and cakes to brownies and bars, much like the simple yet irresistible 5-ingredient chocolate peanut butter bars. The concept of quick and easy no-bake bars also gained popularity in the 1960s and 1970s, as home cooks sought simple ways to create indulgent treats without the hassle of baking. These bars are a direct reflection of that trend, offering a no-bake solution that brings together two beloved ingredients in an easy-to-make form.
Ingredients Breakdown
The beauty of these chocolate peanut butter bars lies in their simplicity. With only five ingredients, you can create a dessert that tastes rich and decadent without spending a lot of time in the kitchen. The base of the bars is made from graham cracker crumbs, which provide a slightly sweet, crunchy texture and help to hold the bars together. Peanut butter is the star ingredient, giving the bars their creamy, nutty flavor. It’s important to use smooth, creamy peanut butter for the best results, as it helps create a smooth, spreadable layer. The chocolate topping is typically made from semi-sweet chocolate chips, which provide a balanced sweetness that pairs perfectly with the peanut butter. For added richness, a bit of butter is often melted with the chocolate to give the topping a smooth, glossy finish. A pinch of salt may be added to enhance the flavors, and if you like a sweeter bar, you can also include a bit of powdered sugar in the peanut butter layer to make it sweeter. The ingredients come together in a harmonious blend, offering a delicious treat that is both simple and indulgent.
Step-by-Step Recipe
- Prepare the Pan: Line an 8×8-inch square baking pan with parchment paper or lightly grease it to prevent sticking.
- Make the Peanut Butter Layer: In a large bowl, combine 1 cup of peanut butter with 1 cup of powdered sugar (if using). Stir until well mixed and smooth. Then, add 1 ½ cups of graham cracker crumbs and mix until everything is fully incorporated.
- Press the Peanut Butter Mixture into the Pan: Transfer the peanut butter mixture into the prepared baking pan. Using a spatula or your fingers, press the mixture down firmly to create an even layer.
- Melt the Chocolate: In a microwave-safe bowl, combine 1 cup of semi-sweet chocolate chips with 2 tablespoons of butter. Heat in 20-30 second intervals, stirring in between, until the chocolate is melted and smooth.
- Pour the Chocolate Over the Peanut Butter Layer: Once the chocolate has melted, pour it over the peanut butter layer, spreading it evenly with a spatula or the back of a spoon.
- Chill and Set: Refrigerate the bars for at least 2 hours, or until the chocolate layer is firm and set.
- Cut and Serve: Once the bars are set, lift them out of the pan using the parchment paper overhang, and cut into squares or bars. Serve and enjoy!
Tips for the Perfect 5-Ingredient Chocolate Peanut Butter Bars
The key to getting these bars just right is pressing the peanut butter mixture firmly into the pan to avoid any air pockets. This will help the bars hold together when you cut them. If you prefer a firmer peanut butter layer, you can refrigerate it for 15-20 minutes before adding the chocolate topping. For the chocolate topping, you can use milk chocolate chips if you prefer a sweeter, creamier taste, or dark chocolate for a more intense, bittersweet flavor. When melting the chocolate, be careful not to overheat it, as this can cause it to seize. Instead, melt it slowly in short intervals and stir in between. If you don’t have graham cracker crumbs, you can substitute them with crushed digestive biscuits, shortbread cookies, or even oats for a different texture. Make sure to refrigerate the bars long enough for the chocolate to harden and set completely; this will ensure clean, smooth cuts when you slice the bars.
Variations and Customizations
While the classic version of these bars is simple and delicious, there are plenty of ways to personalize them. For a crunchier texture, you can add chopped peanuts or even other types of nuts like almonds or cashews to the peanut butter mixture. For a touch of extra flavor, try adding a teaspoon of vanilla extract to the peanut butter layer or a pinch of sea salt on top of the chocolate for that sweet-and-salty contrast. You can also add a drizzle of caramel or white chocolate over the top for an added layer of flavor. If you’re feeling adventurous, mix in a handful of mini marshmallows or coconut flakes into the peanut butter layer for a fun, chewy texture. To make the bars dairy-free, simply substitute the butter with a dairy-free option like coconut oil, and use dairy-free chocolate chips. For a gluten-free version, ensure that the graham cracker crumbs are gluten-free or opt for a gluten-free cookie crumb base.
Health Considerations and Nutritional Value
Although these chocolate peanut butter bars are indulgent, they do offer some health benefits, particularly from the peanut butter, which provides healthy fats, protein, and fiber. The bars also contain graham cracker crumbs, which offer some carbohydrates and small amounts of fiber. However, they are still quite high in calories, fats, and sugars, so they should be enjoyed in moderation. One bar typically contains around 200-250 calories, with most of the calories coming from the fat content in the peanut butter and chocolate. If you’re looking to reduce the sugar content, you can swap the powdered sugar for a sugar alternative like stevia or monk fruit, although this may affect the texture slightly. To make these bars a bit healthier, you could also use natural peanut butter without added sugar and use dark chocolate to reduce the sugar content. While these bars are not a low-calorie snack, they can be a satisfying treat when you’re craving something sweet, and they can also offer a quick energy boost thanks to their combination of protein and healthy fats.

Instructions
- Line an 8-inch or 9-inch square baking pan with aluminum foil or parchment paper. Set aside.

- Butter: Unsalted butter can be used as a substitute. If doing so, add ¼ teaspoon of salt along with the peanut butter in step 2.
- Peanut Butter: For the best texture, I recommend using a processed creamy peanut butter like Jif or Skippy. I do not recommend oily or natural-style peanut butter for this recipe. You can use chunky peanut butter, but the bars may become a little crumbly.
- Graham Crackers: If you can’t find graham crackers, substitute them with 120g of ground digestive biscuits (about 8 biscuits).
- This recipe was updated in 2019 with additional confectioners’ sugar and peanut butter to create thicker bars.
