Irresistible Marbled Nutella Peanut Butter Bars: The Ultimate Fudgy Dessert Recipe
Prepare to tantalize your taste buds with a dessert that beautifully bridges two culinary worlds: our Marbled Nutella Peanut Butter Bars. Much like a harmonious blend of styles, these bars offer a delightful fusion of American comfort (peanut butter) and European decadence (Nutella). Imagine a rich, fudgy peanut butter brownie base, generously swirled with a luxurious, smooth mixture of dark chocolate and hazelnut spread. It’s a match made in heaven for anyone who craves a dessert that’s both comforting and elegantly flavored.
Peanut Butter Bars Swirled With Nutella: A Symphony of Flavors
At the heart of this recipe lies a gorgeously dense and fudgy peanut butter brownie base. This isn’t your average brownie; it’s a testament to the irresistible charm of peanut butter, creating a wonderfully moist and chewy foundation that’s deeply satisfying. Its robust nutty flavor perfectly complements the sweet, creamy swirl layered on top.
The star of the swirl is a luscious blend crafted from premium dark chocolate, rich Nutella, and a touch of butter. This combination creates a marble pattern that’s not only visually appealing but also adds layers of complex flavor. For an intensified hazelnut experience, we highly recommend opting for a dark chocolate bar that’s already infused with hazelnut. Brands like Ritter Sport offer squares with a distinct hazelnut profile that can elevate the swirl significantly. If you’re adventurous, a chocolate bar with hazelnuts and currants could also work, adding a subtle fruity note, provided you don’t mind a few textural surprises. Alternatively, a good quality plain dark chocolate, finely chopped, will still deliver an exquisite chocolatey punch, balancing the sweetness of the Nutella beautifully.
Choosing the right chocolate percentage for your swirl can make a difference. A dark chocolate with 60-70% cacao will provide a robust chocolate flavor without being overly bitter, ensuring it harmonizes with the sweet Nutella. The butter in the swirl mixture helps to achieve that silky, melt-in-your-mouth texture, allowing it to marble effortlessly into the peanut butter batter.
P.S. Patience is key! For the ultimate texture and cleanest cuts, allow these bars to cool completely before serving. Even better, chilling them in the refrigerator for an hour or two will firm them up, enhancing their fudginess and making them much easier to slice into perfect squares. While they are delicious at room temperature, a cold bar offers a delightfully dense and chewy experience that’s hard to beat.
P.P.S. My apologies for the earlier, slightly off-kilter joke. Blame it on the solitude and an overabundance of coffee – sometimes creativity takes unexpected turns!
Marbled Nutella Peanut Butter Bars: Recipe Refinement for Ultimate Fudginess
Recipes, like all good things, evolve. We’ve dedicated time to perfecting these Marbled Nutella Peanut Butter Bars, conducting several rounds of testing to ensure they reach their full potential. While the original version was certainly delicious, our goal was to achieve an even richer, more intensely fudgy texture that would truly make them irresistible. This pursuit led to a couple of key adjustments that we believe significantly enhance the final product.
The most notable change involves the egg composition. We transitioned from using two whole eggs to a combination of one large egg and one large egg yolk. This seemingly small alteration has a profound impact. Egg yolks are rich in fat, which contributes immensely to the fudginess and richness of baked goods. By reducing the whole egg and incorporating an extra yolk, we increased the fat content relative to the protein and water, resulting in a distinctly softer, more tender, and unequivocally fudgier bar. Nobody ever complains about a dessert being too fudgy, and this change truly delivers on that front!
Alongside the egg adjustment, we also reduced the amount of baking powder. Baking powder is a leavening agent responsible for creating lift and airiness in baked goods. By slightly decreasing its quantity, we encouraged a denser crumb structure rather than a cake-like one. This works hand-in-hand with the egg yolk modification to achieve that coveted fudgy chewiness that melts in your mouth.
We understand that individual preferences vary, and while we stand by our updated, fudgier version, we want to empower you to customize these bars to your liking. If you happen to prefer a brownie that is slightly dryer or possesses a more cake-like texture, you can easily revert to the old method by using two whole eggs and one full teaspoon of baking powder. Both versions are incredibly tasty, but for those who prioritize maximum fudginess, our refined recipe is the way to go. Give it a try, and we’re confident you’ll appreciate the delightful improvements!

- Visually Stunning: The marbled pattern is naturally elegant, making these bars a fantastic dessert to share at gatherings or as a special treat.
- Versatile & Adaptable: Easy to customize for different preferences – whether you like them extra fudgy or slightly cakier. Add nuts, sea salt, or different chocolate for variations.
- Crowd-Pleaser: Peanut butter and chocolate are universally loved, and combining them with Nutella creates a dessert that’s guaranteed to disappear fast.
Tips for Achieving the Perfect Swirl and Fudgy Texture:
- Don’t Overmix the Batter: Once you add the flour, mix just until combined. Overmixing develops gluten, which can lead to tough bars.
- Gentle Marbling: When dropping the Nutella mixture, don’t be afraid to be a little messy. For the swirl, a simple back-and-forth or figure-eight motion with a knife or skewer is all you need. Don’t overdo it, or the colors will blend too much.
- Pan Choice Matters: Metal pans conduct heat more efficiently, often resulting in crispier edges. Glass pans retain heat longer and can lead to a more even, slightly softer bake. Adjust baking time slightly if using glass.
- Cooling is Crucial: Seriously, resist the urge to cut into them immediately. Allowing the bars to cool completely, and then chilling them, helps them set properly, making them firmer and easier to slice. This also intensifies the fudgy texture.
- Clean Cuts: For perfectly neat squares, use a sharp knife and wipe the blade clean with a warm, damp cloth after each cut.

Marbled Nutella Peanut Butter Bars

Pin Recipe
Ingredients
- 6 tablespoons unsalted butter, softened (96 grams)
- 1 ¼ cup packed brown sugar (260 grams)
- ½ cup creamy peanut butter (130 grams)
- 1 teaspoon vanilla extract
- 1 large egg
- 1 large egg yolk
- ¾ cup all purpose flour (100 grams)
- ½ teaspoon baking powder
- ¼ teaspoon salt
Swirl Mixture:
- 1 ½ oz dark chocolate (or dark chocolate with hazelnuts) finely chopped
- ½ teaspoon unsalted butter
- ¼ cup Nutella hazelnut spread
Instructions
-
Prepare Your Oven and Pan: Preheat your oven to 325°F (160°C). Line an 8-inch (20cm) square metal baking pan with non-stick foil, or use regular foil and generously grease the bottom and sides to prevent sticking. Pro Tip on Temperature: If you desire noticeable, crispy edges, you can opt for 350°F (175°C). However, 325°F (160°C) generally provides a more even bake throughout the bar, which is ideal for fudginess. If you’re using a glass baking dish, always stick to 325°F (160°C) as glass retains heat more aggressively.

Craft the Peanut Butter Batter: In a large mixing bowl, using an electric mixer on medium speed, cream together the softened unsalted butter and packed brown sugar until the mixture is light, fluffy, and well combined (this usually takes 2-3 minutes). Beat in the creamy peanut butter and vanilla extract until smooth. Next, add the large egg and the single egg yolk, beating just until they are fully incorporated into the mixture. Be careful not to overmix at this stage. Scrape down the sides of the bowl to ensure everything is evenly combined. Sprinkle in the baking powder and salt, beating briefly until they are uniformly distributed. Finally, add the all-purpose flour and stir it in gently with a spoon or spatula until just combined. Overmixing the flour can lead to a tougher bar. Spread this delicious peanut butter batter evenly into your prepared 8-inch square pan.
-
Prepare and Swirl the Nutella Mixture: For the decadent swirl, take your finely chopped dark chocolate and ½ teaspoon of butter and place them in a small microwave-safe bowl. Melt the chocolate and butter together by heating them at 50% power in 30-second intervals, stirring in between, until smooth and fully melted. Remove the melted chocolate from the heat and stir in the ¼ cup of Nutella hazelnut spread until completely combined and glossy. Now, artistic time! Drop spoonfuls of this rich Nutella mixture randomly over the peanut butter brownie batter in the pan. Take a knife, skewer, or a toothpick and gently drag it through the two batters, creating beautiful swirls and marbled patterns. Don’t overmix the swirl, a few passes are enough to create an appealing design.
-
Bake to Perfection: Place the pan on the center rack of your preheated oven and bake for approximately 30 minutes. The bars are ready when the edges begin to slightly pull away from the sides of the pan and the center appears mostly set but might still seem a little soft. This softness in the center is exactly what you want for a perfectly fudgy texture; don’t overbake! The edges will likely be puffed up and golden. Once baked, remove the pan from the oven and immediately place it on a wire rack to begin cooling.
-
Cool, Chill, and Serve: Allow the Marbled Nutella Peanut Butter Bars to cool completely in the pan on the wire rack until they reach room temperature. This step is crucial for the bars to properly set and achieve their optimal texture. For an even firmer and tidier slice, once at room temperature, transfer the pan to the refrigerator and chill them for at least an hour, or until they are thoroughly cold. Once chilled, lift the entire slab of bars from the pan using the foil lining, transfer it to a cutting board, and cut into 12 delicious squares. Enjoy!
Storage and Serving Suggestions:
These Marbled Nutella Peanut Butter Bars are perfect for making ahead! Store them in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. If refrigerated, allow them to come to room temperature for about 15-20 minutes before serving for optimal softness, or enjoy them cold for a chewier, fudgier bite. They also freeze beautifully for up to 2-3 months; simply wrap individual bars tightly in plastic wrap and then foil, then thaw at room temperature when cravings strike. Serve them as an after-dinner treat, a delightful snack, or even warmed slightly with a scoop of vanilla ice cream for an extra indulgent experience.
