How to Make Hazella Brownie Sundae Recipe

Step 1: Preparing the Batter

Start by preheating your oven to 180°C fan bake to get everything ready for the perfect bake. Line a 26 x 32 cm tray with baking paper—it ensures your brownies lift out effortlessly and keeps the edges perfectly soft. In a mixing bowl, combine the sugar, salt, vanilla, oil, and melted butter, whisking them together until smooth. Adding the eggs one at a time and whisking well ensures the batter becomes light and glossy, setting the stage for fudgy brownies that melt in your mouth.

Step 2: Mixing the Dry Ingredients

Sift the flour, cocoa powder, and baking powder directly into the wet mixture. Sifting prevents lumps and ensures a silky batter. Gently fold the dry ingredients until the mixture is smooth, with no streaks of flour or cocoa, creating a luxurious chocolate base that’s neither too thick nor too runny.

Step 3: Adding the Hazella Chocolate

Break up 125g of Whittakers Hazella Chocolate into squares and toggle them through the batter, distributing the hazelnut-studded chocolate evenly. These chunks will melt during baking, creating little pockets of gooey delight that elevate every bite.

Step 4: Baking to Perfection

Pour the batter into your lined tray, spreading it out evenly so every slice has its share of chocolate treasures. Place it in the oven and bake for 25-30 minutes until the edges are set and the center springs back lightly when you press it with your fingertip. This slight springiness is the key to achieving that moist, fudgy texture that makes this Hazella Brownie Sundae Recipe so extraordinary. Let the brownies cool for at least 30 minutes before cutting to lock in their structure and flavors.

Step 5: Optional Chocolate Drizzle

For a finishing touch, gently melt the remaining 50g of Whittakers Hazella Chocolate in short bursts in the microwave, stirring each time to avoid burning. Add a little oil to thin the melted chocolate until it’s perfect for drizzling. This drizzle doesn’t just look gorgeous but adds an extra luscious, nutty chocolate layer that’s utterly divine.

Garnishes

Serving your Hazella Brownie Sundae with a scoop of creamy vanilla ice cream is a no-brainer—its cold smoothness cuts through the warm, rich brownies beautifully. Sprinkle toasted chopped hazelnuts on top for crunch and amplified nutty flavor. A glossy drizzle of melted Hazella chocolate completes this stunning dessert, making every spoonful a perfect balance of creamy, crunchy, and indulgent.

Side Dishes

This decadent sundae pairs wonderfully with freshly brewed coffee or a glass of cold milk for a comforting combo. If you want to elevate the experience, try serving alongside a simple fruit salad with tart berries to add a refreshing contrast that brightens the richness of the brownies and ice cream.

Creative Ways to Present

Why not layer your brownie pieces, ice cream, and hazelnuts in tall glasses for an elegant brownie parfait? Or assemble mini sundae jars for parties, making it easy for guests to grab and enjoy. You can even experiment by adding a splash of hazelnut liqueur to the ice cream for an adult twist on the classic Hazella Brownie Sundae Recipe.

Make Ahead and Storage

Storing Leftovers

Keep any leftover brownies stored in an airtight container at room temperature for up to three days, where they’ll stay moist and fresh. If you’ve already topped them with ice cream, be sure to store the components separately for the best texture.

Freezing

For longer storage, wrap individual brownie pieces tightly in plastic wrap and place them in a freezer-safe bag. Frozen brownies can be kept for up to two months and make a great ready-to-go treat—just thaw them at room temperature or enjoy them slightly frozen for a chilly twist.

Reheating

To enjoy brownies warm, pop them in the microwave for 15-20 seconds or heat gently in the oven at 160°C for about 5 minutes. Freshen them up with a scoop of vanilla ice cream and a sprinkle of toasted hazelnuts to recreate that flawless Hazella Brownie Sundae experience at home.

FAQs

Can I use a different type of chocolate instead of Whittakers Hazella?

While Whittakers Hazella Chocolate adds a signature hazelnut flair, you can substitute with other hazelnut or milk chocolates if you prefer. Just be mindful that the texture and nutty flavor may vary slightly.

Is there a vegan version of the Hazella Brownie Sundae Recipe?

Yes, you can try replacing the butter with coconut oil, using flax eggs instead of real eggs, and opting for dairy-free chocolate and ice cream. The results will be a bit different, but still delicious!

How do I know when the brownies are done baking?

Check by gently pressing the center with your fingertip. It should spring back slightly but still feel soft. If it’s too wobbly or wet, it needs more time. Overbaking will dry them out, so keep a close eye toward the end.

Can I prepare the brownie batter ahead of time?

Yes, you can make the batter a few hours in advance and keep it covered in the fridge. Let it come to room temperature before baking for best results. This is great for prepping dessert in advance.

What’s the best way to toast hazelnuts for the sundae?

Toast them in a dry skillet over medium heat for about 5 minutes, shaking often, until fragrant and golden. Let them cool before chopping to preserve their crunch and flavor.
