Ultimate Devil’s Food Nutella Brownies: An Easy Recipe
Our journey into the world of cake mix baking began with a batch of delightful strawberry brownies made from cake mix, which were an instant hit. Since then, we’ve become enthusiasts of various cake mix recipes and hacks, even venturing into making fun cake mix donuts. This time, inspired by the rich, nutty flavor it brings to everything from sandwiches to desserts, we decided to incorporate Nutella into our Devil’s Food brownies. The outcome was nothing short of spectacular: fudgy, deeply chocolatey brownies with a subtle hazelnut undertone that will have everyone asking for more. This recipe proves that exceptional desserts don’t always require a long list of ingredients or complex techniques.

Essential Tips for Perfect Cake Mix Brownies
Achieving the perfect fudgy brownie texture from a cake mix is simple, but it requires a slight deviation from the box instructions. Our secret lies in the precise balance of ingredients and, crucially, avoiding overbaking. The goal is to bake them just until the edges are golden brown and appear slightly firm or cake-like, while the center still seems a bit underdone. This delicate balance ensures a lusciously moist and fudgy interior. Once removed from the oven, the residual heat will continue to cook the brownies slightly, bringing them to absolute perfection.
When selecting your ingredients, the quality of your Devil’s Food chocolate cake mix truly makes a difference. While many brands are available, we highly recommend opting for a reputable name brand. Often, a slight extra investment in a quality mix translates to superior flavor and texture in your final product. Beyond the mix, here are a few key ingredients and tools that will elevate your brownie baking:
- Eggs: Using eggs at room temperature is crucial. They incorporate more evenly into the batter, leading to a smoother mixture and a better overall texture.
- Oil: A neutral vegetable oil works best. For a healthier alternative or to add a subtle hint of moisture without altering the flavor, consider using canned pumpkin puree.
- Nutella: This is the star ingredient for enhancing fudginess and introducing that delightful hazelnut-chocolate complexity. It’s optional, but highly recommended for a richer brownie.
- Baking Pan: An 8×8 inch baking pan is ideal for achieving thick, chewy brownies. Always prepare it with a non-stick cooking spray or line it with parchment paper for easy removal.
Customize Your Brownies: Delicious Variations and Add-Ins
The beauty of this Nutella cake mix brownie recipe is its adaptability. While delicious on its own, you can easily customize it with a variety of add-ins to suit your preferences. Consider stirring in 1/4 cup of crushed nuts, such as walnuts or pecans, for added crunch and earthy flavor. For an even more intense chocolate experience, fold in semi-sweet, milk, or even white chocolate chips. Peanut butter chips offer a delightful sweet and salty contrast, while a handful of colorful sprinkles can add a festive touch.
Once your brownies are baked to perfection and cooled, the topping possibilities are endless. A drizzle of chocolate syrup, a dollop of rich cream cheese frosting, or a scoop of vanilla bean ice cream can take these brownies to the next level. However, we often find them to be sheer perfection on their own, requiring no additional embellishments. If you’re a fan of slow-cooker desserts, this recipe can even be adapted to make delicious Crockpot brownies, offering another convenient baking method for busy days.

How to Make Fudgy Brownies Every Time: The Key to Perfection
Whether you’re making a cake or these decadent brownies from a deep chocolate mix, the most critical step to achieving a truly fudgy texture is to avoid overbaking. Observe our brownies in the photos: they are ooey-gooey and incredibly moist, yet perfectly set—not liquid or raw. This is the ideal consistency you’re aiming for. In our experience, approximately 24 minutes in a preheated oven yields perfect results, though baking times can vary slightly depending on your oven and altitude. For your first batch, we recommend starting to check for doneness around the 21-minute mark. You want the edges to be just barely browned and the middle to show signs of firming up without being completely dry. Trust us, leaving them slightly underdone will result in an unforgettable fudgy experience you won’t regret.
Should You Let Brownies Cool in the Pan? Understanding the Cooling Process
Yes, absolutely! Allowing your brownies to cool completely in the pan is a crucial step for achieving the desired texture and making them easier to cut. As they rest on a cooling rack within the pan, the brownies undergo what’s known as “carry-over cooking.” This means the internal temperature remains high enough for a period, continuing to set the middle without drying out the edges. This process also helps the brownies solidify further, making them much more stable and preventing them from falling apart when sliced. For those who love a truly fudgy brownie, chilling them in the refrigerator for a couple of hours after they’ve cooled to room temperature can enhance their dense, rich texture and make for even cleaner cuts.
Beyond this brownie recipe, we offer numerous cake mix hacks. For instance, you can add an extra egg yolk to a cake mix for enhanced richness or use hot water to “bloom” the cocoa in chocolate mixes, intensifying their flavor. These small tips can make a significant difference in your baking endeavors.
Baking Cake Mix Brownies in an Air Fryer: A Quick & Convenient Method
For a quicker bake or if you prefer using smaller portions, you can certainly bake these cake mix brownies in an air fryer. Due to the typically smaller size of air fryer baking pans, you’ll likely need to bake them in two separate batches. Our dedicated air fryer brownies from mix guide provides more specific instructions, but the principle remains the same: monitor them closely. For an intensely ooey-gooey texture, remove them slightly earlier than you might in a conventional oven. If you lean towards a more cake-like brownie, a few extra minutes will achieve that perfectly firm yet tender crumb. The air fryer offers a fantastic way to enjoy freshly baked brownies with less waiting time.

Optimal Cooling Time: How Long Should Brownies Cool in the Pan?
The ideal cooling time for brownies in the pan is approximately 15 minutes. This window allows the brownies to set and firm up just enough to be handled and cut cleanly into perfect squares, without becoming overly dry. If you attempt to remove or cut them too soon, they will likely be too soft and fall apart. Conversely, leaving them in the pan for too long can lead to a drier texture, especially if your pan retains heat significantly. After the initial 15-minute rest, you can transfer them to a wire rack to cool completely, or, if you prefer, slice and enjoy them warm for a truly comforting treat.
For the fudgiest results, once slightly cooled in the pan, the easiest way to remove them is by lining your baking pan with parchment paper before adding the batter. When baked, carefully lift the entire sheet of brownies out of the pan using the parchment paper and transfer it to a wire rack to cool completely. For an extra dense, fudgy texture, you can chill the cooled brownies in the refrigerator for a couple of hours before cutting. This helps the chocolate set beautifully and creates that desirable rich, chewy consistency.
While you could technically scoop your Devil’s Food brownies out of the pan immediately, they tend to be quite delicate and might not hold their shape. For neatly cut squares, patience is key. Allow them to cool sufficiently in the pan, and if you’ve used non-stick spray or parchment paper, they will slice beautifully and present perfectly. Once you’ve mastered these, be sure to try our equally delicious red velvet brownies with cake mix for another delightful variation.

Instructions
-
In a large mixing bowl, combine the box of Devil’s Food cake mix with the eggs and vegetable oil. Mix until just combined, being careful not to overmix.
-
Gently fold in the Nutella until streaks are visible, creating a beautiful swirl. If adding optional chopped nuts (up to 1/2 cup), incorporate them now.

Prepare an 8×8 inch baking pan by greasing it with non-stick spray or lining it with parchment paper, leaving an overhang on the sides for easy removal.
-
Spread the brownie batter evenly into the prepared pan. Bake in a preheated oven at 350°F (175°C) for approximately 21-24 minutes. Crucially, do NOT overbake. Baking time can vary based on oven calibration and altitude. Brownies are done when the edges are set and slightly browned, and the center appears just barely firm to the touch, with a few moist crumbs clinging to a toothpick inserted into the center (not clean).
-
Remove the pan from the oven and place it on a wire cooling rack. Allow the brownies to cool completely in the pan before attempting to cut them. This step is essential for achieving fudgy brownies that hold their shape.

Notes
How to Know When Brownies are Done
For fudgy brownies, they are perfectly done when the outsides are slightly cracked, the middle is just beginning to crack, and it feels slightly firm to the touch. A toothpick inserted into the center should come out with moist crumbs attached, but not wet batter. Always allow them to cool completely in the pan on a cooling rack to allow them to continue setting before slicing.
For a more cakey brownie, you’ll want the entire top to be cracked, with the center firm to the touch. A toothpick inserted here should come out clean.
