Fudgy Nutella Stuffed Brownies: Best Easy Homemade Dessert

I still remember the exact moment I realized I’d never order dessert from a restaurant again. It was a rainy Tuesday, my partner was complaining about being tired, and we were debating between ordering pizza or just making something quick. I was feeling particularly indulgent that night—maybe it was the stress, maybe it was just the weather—but I decided to stop by the store for a box of brownie mix. I know, I know. Don’t judge me. Sometimes you just need the shortcut.

But then I saw it. The jar. Nutella. Not just any jar, but the one I’d been hoarding for special occasions, waiting for the “perfect” moment. Well, this rainy Tuesday felt pretty perfect. I grabbed the jar, went home, and decided to stuff my brownies with it. I didn’t have a fancy recipe. I just had a box mix, a spoon, and a desperate need for chocolate.

When they came out of the oven, they were a mess. The Nutella had oozed out, creating these gooey, chocolatey lava pools that stained the pan. I scraped them out, burned my tongue on the first bite, and sat on my kitchen floor eating them with a spoon. That’s when I knew: these were different. These were better than anything I’d ever bought at a bakery. Better than takeout. Better than even the fancy dessert places downtown.

That accidental discovery turned into an obsession. I’ve made these Fudgy Nutella Stuffed Brownies probably two dozen times since then. I’ve tweaked the recipe, tested different brands of brownie mix, and even tried making the batter from scratch. The result? A brownie that’s dense, fudgy, and absolutely loaded with that hazelnut-chocolate center that melts in your mouth. They’re rich, they’re decadent, and they’re surprisingly easy to make. If you’re looking for a dessert that will make your friends and family lose their minds, this is it. And trust me, you won’t be ordering takeout dessert again.

Why You’ll Love These Nutella Stuffed Brownies

Look, I’m not trying to sell you on the idea that you need to bake every single day. But when you do want something sweet, these Fudgy Nutella Stuffed Brownies are the answer. They’re not just brownies; they’re an experience. Here’s why they’ve become my go-to dessert for everything from movie nights to holiday gatherings:

• The Gooey Factor — Seriously, the center is pure magic. When you bite into one, the Nutella spills out like lava. It’s not just a filling; it’s a surprise that makes every bite feel special. I’ve watched people’s eyes light up when they take that first bite.
• Stupid Simple — You don’t need to be a baker to make these. I use a boxed brownie mix as a base, which means I’m not measuring flour, cocoa powder, and sugar. I just mix, scoop, stuff, and bake. If you can boil water, you can make these. I’ve made them while half-asleep on Sunday mornings.
• Crowd-Pleaser — I’ve served these to my picky-eater niece, my chocolate-obsessed brother, and even my health-conscious friend (who still asked for seconds). Everyone loves them. They’re rich but not overly sweet, and the hazelnut flavor adds a sophisticated twist.
• Perfect for Meal Prep — Unlike some desserts that taste best fresh out of the oven, these actually get better after sitting in the fridge for a day. The flavors meld together, and the brownie becomes even fudgier. I make a batch on Sunday, and I have dessert for the rest of the week. It’s like having my own personal bakery.
• Budget-Friendly — You don’t need expensive ingredients. A box of brownie mix, a jar of Nutella, and some basic pantry staples. It’s way cheaper than buying a box of gourmet brownies from the store, and they taste way better.

This is my answer to “what’s for dessert?” when I want something indulgent but don’t want to spend hours in the kitchen. It’s reliable, it’s delicious, and it always makes everyone happy.

Ingredients You’ll Need

Here’s the best part: you probably have most of these ingredients already. I’m particular about a few things, but mostly, this is a simple list. I’ll tell you exactly why each one matters.

For the Brownie Base

Boxed Brownie Mix (1 box, usually 18-19 oz) — I use any standard brand like Ghirardelli or Duncan Hines. Dark chocolate brownie mix is my preference because it’s less sweet and lets the Nutella shine. If you want to go from scratch, I have a recipe for homemade brownie batter that works just as well, but the box mix is faster.

Vegetable Oil (1/3 cup) — I use vegetable oil because it keeps the brownies fudgy. Butter works too, but it can make them cakey. If you’re using butter, melt it first.

Water (1/3 cup) — Some people use milk for a richer flavor, but water keeps the texture dense. If you’re using milk, reduce the amount slightly to account for the extra fat.

Eggs (2 large) — Room temperature eggs are best. They help bind the batter and add structure. Don’t skip them, or the brownies won’t set properly.

Vanilla Extract (1 teaspoon) — Just a splash to enhance the chocolate flavor. Pure vanilla is best, but imitation works in a pinch.

For the Filling

Nutella (1 jar, 13 oz) — This is the star. Use the real thing, not a generic hazelnut spread. The texture and flavor of Nutella are unique, and it makes a huge difference. I keep a jar stocked at all times.

Optional Add-ins

Chocolate Chips (1/2 cup) — I sometimes add semi-sweet chocolate chips to the batter for extra chocolatey goodness. It’s optional, but if you’re a chocolate lover, go for it.

Sea Salt (pinch) — A sprinkle of flaky sea salt on top after baking enhances the sweetness and adds a nice contrast. I love the salty-sweet combo.

Whipped Cream — For serving. I like to serve these warm with a dollop of whipped cream on top. It’s like a dessert from a high-end cafe.

Equipment Needed

You don’t need fancy equipment for this. Here’s what I actually use:

9×13 Inch Baking Pan — I use a metal pan for even baking. Glass pans work too, but you might need to reduce the baking time by 5 minutes. Line it with parchment paper for easy removal.

Mixing Bowls — Two medium bowls. One for the brownie batter, one for any extra mix-ins.

Whisk or Fork — To mix the batter. A whisk is better, but a fork works if you’re in a hurry.

Spoon or Small Scoop — For portioning the Nutella. I use a teaspoon to make uniform dollops.

Spatula — For spreading the batter and scraping the bowl.

Cooling Rack — To cool the brownies. Don’t skip this, or they’ll get soggy.

How to Make It: Step-by-Step

Alright, let’s make this! I’m walking you through exactly how I do it, including the little tricks I’ve picked up.

Step 1: Prep Your Pan (2 minutes)

Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This makes it easy to lift the brownies out once they’re done. Grease the parchment paper lightly with oil or butter to prevent sticking.

Step 2: Make the Brownie Batter (5 minutes)

In a large mixing bowl, combine the brownie mix, vegetable oil, water, eggs, and vanilla extract. Mix with a whisk or fork until just combined. Don’t overmix, or the brownies will be tough. The batter should be thick and glossy. If you’re adding chocolate chips, fold them in now.

Step 3: Portion the Nutella (3 minutes)

Take your jar of Nutella and scoop out small dollops, about 1 teaspoon each. You’ll need about 15-20 dollops for a 9×13 pan. Place them on a plate or small tray. This step takes a minute, but it’s crucial for even distribution.

Step 4: Assemble the Brownies (5 minutes)

Scoop half of the brownie batter into the prepared pan and spread it evenly. This is your base layer. Then, place the Nutella dollops on top of the batter, spacing them about 1 inch apart. Be generous—don’t skimp on the Nutella!

Step 5: Cover with Remaining Batter (3 minutes)

Scoop the remaining brownie batter over the Nutella dollops. Use a spoon or spatula to gently spread it, making sure to cover the Nutella completely. You don’t need to be perfect; the batter will settle as it bakes. If you see any Nutella peeking out, that’s okay—it’ll create those gooey pools.

Step 6: Bake (25-30 minutes)

Place the pan in the preheated oven and bake for 25-30 minutes. The brownies are done when a toothpick inserted into the center comes out with moist crumbs (not wet batter). If the toothpick is clean, they’re overbaked. Keep an eye on them around the 25-minute mark.

Step 7: Cool and Slice (30 minutes)

Let the brownies cool in the pan for at least 30 minutes. This is the hardest part, but it’s necessary for clean slicing. If you cut them hot, they’ll fall apart. Once cooled, lift them out of the pan using the parchment paper overhang. Slice into squares and serve.

Expert Tips & Tricks

Here’s everything I’ve learned from making these dozens of times. These tips will save you from my mistakes.

Don’t Overbake

This is the #1 mistake. Brownies continue to cook after you take them out of the oven. If you wait until the toothpick is clean, they’ll be dry. Aim for moist crumbs. If you prefer fudgier brownies, pull them out even earlier.

Use Room Temperature Ingredients

Make sure your eggs are at room temperature. Cold eggs can cause the batter to separate, leading to uneven baking. If you forget, just soak the eggs in warm water for 5 minutes.

Chill the Nutella Dollops

If you’re worried about the Nutella leaking out too much, pop the dollops in the freezer for 10 minutes before placing them in the batter. This helps them hold their shape longer.

Add a Pinch of Salt

A pinch of sea salt on top after baking enhances the chocolate flavor and balances the sweetness. It’s a small step that makes a big difference.

Store Properly

Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. They actually taste better after sitting for a day.

Variations & Substitutions

Once you’ve nailed the basic version, here’s how you can mix it up. I’ve tried all of these.

Gluten-Free

Use a gluten-free brownie mix. Everything else is naturally gluten-free. I’ve used Bob’s Red Mill gluten-free mix, and it works great.

Dairy-Free

Replace Nutella with a dairy-free hazelnut spread (like Nutella’s own dairy-free version or a homemade alternative). Use vegan brownie mix and dairy-free chocolate chips.

Less Sweet

Use dark chocolate brownie mix and reduce the amount of Nutella by half. Add a sprinkle of sea salt to balance the sweetness.

Add-Ins

Stir in chopped walnuts or pecans for crunch. Or add a layer of caramel sauce between the batter and Nutella for extra richness.

Mini Muffin Version

Divide the batter and Nutella into a muffin tin. Bake for 15-18 minutes. Perfect for portion control and party favors.

Serving & Storage

How to serve these bad boys:

Warm and Gooey — Microwave individual brownies for 10-15 seconds to warm the Nutella center. Serve with a scoop of vanilla ice cream or a dollop of whipped cream.

Cold and Fudgy — Serve them straight from the fridge. They’re denser and more intense. Great for lunchboxes or snacks.

Party Style — Cut them into small squares and serve on a platter with toothpicks. They disappear fast!

Storage — Keep in an airtight container at room temperature for 3 days. For longer storage, refrigerate for up to a week. They freeze well too! Wrap individual brownies in plastic wrap and freeze for up to 3 months. Thaw at room temperature before serving.

Reheating — To reheat, microwave for 10-15 seconds. Don’t overdo it, or the Nutella will become too runny. You want it warm and gooey, not liquid.

Frequently Asked Questions

Can I use homemade brownie batter instead of box mix?

Absolutely! I have a recipe for homemade brownie batter that works just as well. Just make sure it’s thick and fudgy, not cakey. If your homemade batter is too thin, add a little more flour.

Why did my Nutella leak out?

This usually happens if the brownies are overbaked or if you didn’t cover the Nutella dollops completely with batter. Make sure to spread the top layer of batter evenly over the Nutella. Also, don’t overbake—remove the brownies when the toothpick has moist crumbs.

Can I make these ahead of time?

Yes! Make the brownies up to 2 days ahead and store in an airtight container at room temperature. They actually taste better after sitting for a day as the flavors meld together. You can also freeze them for up to 3 months.

Can I use a different nut butter?

You can, but Nutella is unique because of its hazelnut and chocolate flavor. Peanut butter or almond butter will work, but the taste will be different. I recommend sticking with Nutella for the classic flavor.

How do I store leftovers?

Store in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. They freeze well too! Wrap individual brownies in plastic wrap and freeze for up to 3 months.

Can I double this recipe?

Yes! Double all ingredients and use a larger pan (like a 9×13 inch pan for a double batch, or two 8×8 inch pans). Baking time may increase by 5-10 minutes, so keep an eye on them.

Why are my brownies cakey instead of fudgy?

This usually happens if you overmix the batter or use too much flour. Make sure to mix just until combined. Also, use a fudgy brownie mix, not a cakey one. If using homemade batter, reduce the amount of flour slightly.
