This indulgent creation features moist, fudgy brownies baked to perfection and paired with creamy vanilla ice cream.

Perfect for a quick, easy dessert that satisfies chocolate cravings with a balance of sweetness and crunch.
I still remember the first time I made chocolate brownie sundaes for my roommates in college. It was a lazy Sunday afternoon, and I wanted to impress them without spending hours in the kitchen. I pulled together what I had—melted butter, sugar, eggs, and cocoa powder—and within an hour, we were gathered around bowls of warm, fudgy brownies topped with melting vanilla ice cream and rich chocolate sauce. That simple dessert became our go-to celebration, the one we'd make whenever something worth celebrating happened. Now, every time I prepare it, I'm transported back to that kitchen, to the laughter and the way chocolate sauce dripped down the sides of the ice cream.
I'll never forget when my nephew took his first bite of this sundae at his birthday party. His eyes went so wide, and he just kept saying 'more chocolate, more chocolate.' That's when I realized this wasn't just a dessert—it was a moment creator, something that made people happy in the simplest, most delicious way.
Ingredients
- Unsalted butter (115 g or 1/2 cup), melted: Melted butter creates that fudgy texture you're after. I learned the hard way that using cold butter means you'll overmix the batter trying to combine it, which makes brownies tough.
- Granulated sugar (200 g or 1 cup): This is your brownie's sweetness and structure. Don't skip it or reduce it—the sugar helps create those beautiful crackly edges.
- Large eggs (2): Eggs bind everything together and add richness. Room temperature eggs mix in more smoothly, so pull them out of the fridge 10 minutes before baking.
- Vanilla extract (1 tsp): A small amount that deepens the chocolate flavor without tasting vanilla-forward. Pure extract makes a noticeable difference.
- All-purpose flour (65 g or 1/2 cup): Keep your flour measurements precise—too much makes them cakey, too little makes them greasy. Spoon and level, don't scoop directly.
- Unsweetened cocoa powder (40 g or 1/3 cup): This is where the chocolate magic happens. Sifting it prevents lumps that can hide in your batter.
- Salt (1/4 tsp): A small pinch that makes the chocolate flavor sing. It's the secret ingredient no one notices but everyone tastes.
- Vanilla ice cream (1.5 liters or 6 cups): Let it soften slightly at room temperature for 5 minutes before scooping—it makes a beautiful, creamy serving.
- Chocolate sauce (180 ml or 3/4 cup): Warm it gently before drizzling so it pools beautifully over the ice cream. Store-bought is fine, but homemade adds a personal touch.
- Chopped toasted nuts (60 g or 1/2 cup): Pecans, walnuts, or peanuts all work. Toasting them first brings out their deep, roasty flavor that contrasts perfectly with sweet ice cream.
Instructions
- Prepare your pan:
- Preheat your oven to 180°C (350°F) and line your 20 cm (8-inch) square baking pan with parchment paper. This tiny step saves you so much heartache when it's time to lift those brownies out. I like to press the parchment into the corners and let the edges stick up a bit—it gives you something to grab.
- Combine your wet ingredients:
- In a mixing bowl, whisk together the melted butter and sugar until they're completely combined and look like wet sand. This should take about a minute. Add your eggs one at a time, whisking well after each addition, then stir in the vanilla extract until the mixture is smooth and glossy. You want it to look almost like chocolate mousse at this point.
- Sift in the dry ingredients:
- Sift the flour, cocoa powder, and salt directly over your wet mixture. This is the moment where patience matters—stir gently until the dry ingredients just disappear into the batter. You'll know you're done when you don't see any white flour streaks. The key is to not overmix; a few gentle folds with your spatula are all you need. Overmixing develops gluten and makes brownies tough rather than fudgy.
- Pour and bake:
- Pour the batter into your prepared pan and use a spatula to smooth the top into an even layer. Slide it into the oven and bake for 22–25 minutes. You're looking for a toothpick inserted into the center to come out with moist crumbs clinging to it—not clean, not wet, but glistening with chocolate. This is the difference between fudgy and undercooked, and it matters.
- Cool and cut:
- Let the brownies cool completely in the pan before cutting. I know it's tempting to slice them warm, but they'll fall apart. Once they're cool, use a sharp knife dipped in hot water (and wiped clean between cuts) to slice them into six equal squares. Each brownie should be about 10 cm (4 inches) on each side.
- Assemble your sundaes:
- Place a brownie square in the bottom of each serving bowl or plate. Top with a generous scoop of vanilla ice cream that's been sitting out for just 5 minutes so it's creamy but not melted. Drizzle warm chocolate sauce generously over the ice cream, letting it pool around the brownie. Sprinkle your toasted nuts over the top, add whipped cream if you're feeling indulgent, and crown it all with a maraschino cherry. Serve immediately so the ice cream is still cold but the chocolate sauce is still warm.
There's something magical about the moment when someone takes their first spoonful of brownie, ice cream, and chocolate sauce all together. It's the pause, that little intake of breath, and then the smile. That's the moment I'm chasing every time I make this.
Making Your Brownie Perfectly Fudgy
The secret to fudgy brownies lives in restraint. Resist the urge to bake them until a toothpick comes out clean—that's cake. You want that toothpick to come back glistening with chocolate and studded with moist crumbs. It feels risky the first time, like you're underbaking them, but that's exactly the point. The heat in the pan will continue cooking them for a few minutes after you pull them out of the oven. Once they cool, they'll set perfectly, with that dense, almost melting texture that makes people close their eyes when they eat them.
Ice Cream and Sauce Temperature
The magic of this dessert happens at the temperature contrast. Cold ice cream melting into warm chocolate sauce over a fudgy brownie is what makes this sundae transcendent. Before serving, let your vanilla ice cream sit on the counter for about 5 minutes so it's soft enough to scoop beautifully but still cold. Warm your chocolate sauce gently on the stovetop or in the microwave—it should be warm enough to drizzle easily but not so hot it cooks the ice cream. This attention to temperature is what separates a good dessert from one people talk about for years.
Variations and Personal Touches
Once you've made this sundae once, you'll start seeing possibilities everywhere. The brownie base is forgiving and delicious, but the toppings are where you can really make it your own. Try swapping vanilla ice cream for coffee, caramel, or even salted chocolate for something richer. If nuts aren't your thing, use chocolate chips, crushed cookies, or fresh berries—whatever makes your heart happy. For a nut-free version, simply omit the nuts and double-check that your ice cream and chocolate sauce don't contain traces of nuts if allergies are a concern.
- Coffee ice cream transforms this into an evening dessert that pairs beautifully with espresso.
- Caramel sauce instead of chocolate creates a different kind of indulgence—sweet, buttery, equally irresistible.
- A drizzle of salted caramel and a sprinkle of sea salt elevates the whole experience into something sophisticated.
This brownie sundae is the kind of dessert that doesn't need to be fancy to feel special. It's in the warmth of sharing it, in the moment of pure enjoyment, in the way it brings people together around something delicious and unpretentious.
