Ingredients
The foundation of any great brownie is a harmony of rich cocoa, butter, and sugar. Here we add Nutella for that unmistakable hazelnut‑chocolate swirl, while a touch of espresso powder deepens the cocoa flavor. A sprinkle of flaky sea salt on top creates a delightful contrast that makes each bite sing.
Main Ingredients
- 1 ½ cups all‑purpose flour
- ¾ cup unsweetened cocoa powder
- ¼ teaspoon espresso powder
Wet Ingredients
- ¾ cup unsalted butter, melted
- 1 ¼ cups granulated sugar
- 3 large eggs, room temperature
- 1 ½ teaspoons pure vanilla extract
Nutella Swirl & Toppings
- ½ cup Nutella (hazelnut‑chocolate spread)
- ¼ teaspoon flaky sea salt, for garnish
These ingredients work together to create a brownie that’s both dense and airy. The melted butter and sugar form a glossy, chewy base, while the cocoa and espresso powder give depth. Nutella adds a creamy, nutty ribbon, and the final pinch of sea salt lifts the chocolate flavor, making each forkful unforgettable.
Step-by-Step Instructions
Preparing the Batter
Start by preheating your oven to 350°F (175°C) and greasing a 9‑inch square pan with butter or parchment. In a medium bowl whisk together the flour, cocoa powder, and espresso powder; this ensures the dry ingredients are evenly distributed and prevents lumps.
Mixing Wet Components
In a large mixing bowl combine melted butter and sugar, stirring until the mixture is glossy and slightly cooled. Beat in the eggs one at a time, allowing each to incorporate fully before adding the next. Finish with vanilla extract, which adds a subtle aromatic backdrop.
Creating the Fudgy Base
- Combine wet and dry. Gently fold the flour‑cocoa mixture into the butter‑egg mixture using a spatula. Stir just until you see no dry streaks; over‑mixing would develop gluten and make the brownies cakey.
- Swirl in Nutella. Drop the Nutella in three generous spoonfuls over the batter. Using a knife or skewer, swirl the Nutella in a figure‑eight pattern, creating ribbons without fully mixing it in.
- Transfer to pan. Pour the batter into the prepared pan, smoothing the top with the spatula. Sprinkle flaky sea salt evenly across the surface; the salt will caramelize slightly during baking, enhancing the chocolate flavor.
- Bake to perfection. Place the pan in the center of the oven and bake for 30‑35 minutes. The edges should look set while a toothpick inserted near the center comes out with a few moist crumbs—this is the hallmark of a fudgy brownie.
- Cool and cut. Allow the brownies to cool completely in the pan (about 20 minutes) before lifting them out with the parchment and cutting into 12 squares. Cooling helps the crumb set and makes clean cuts.
Finishing Touches
Serve the brownies warm with a scoop of vanilla ice cream, a drizzle of extra Nutella, or simply dust them with powdered sugar. The combination of warm fudgy chocolate and the silky Nutella swirl makes each bite an indulgent experience.
Tips & Tricks
Perfecting the Recipe
Room‑temperature eggs. Using eggs that are not cold helps them emulsify with butter, giving a smoother, more cohesive batter.
Don’t over‑mix. Once the flour is added, mix only until just combined. This prevents gluten development and keeps the brownies dense.
Even swirls. Drop Nutella in distinct blobs and swirl quickly; lingering too long will blend the colors and lose the ribbon effect.
Flavor Enhancements
Add a teaspoon of instant coffee granules to the dry mix for an extra depth of chocolate flavor, or fold in toasted hazelnut pieces for crunch. A light drizzle of caramel sauce just before serving adds a sweet contrast.
Common Mistakes to Avoid
Opening the oven too early can cause the brownies to sink. Also, avoid using too much flour; a level measuring cup is essential. Finally, don’t skip the cooling step—cutting while hot leads to crumbly pieces.
Pro Tips
Use high‑quality cocoa. A Dutch‑process cocoa gives a richer, smoother chocolate flavor than natural cocoa.
Line the pan with parchment. This ensures a clean release and preserves the beautiful top crust.
Check with a toothpick. A few moist crumbs indicate fudginess; a clean toothpick means you’ve baked too long.
Finish with flaky salt. The tiny bursts of salt brighten the chocolate and create a sophisticated flavor contrast.
Variations
Ingredient Swaps
Replace the butter with an equal amount of coconut oil for a subtle tropical note, or swap half the all‑purpose flour for almond flour to add a nutty richness. For a darker chocolate flavor, use 70% cocoa chocolate chips mixed into the batter.
Dietary Adjustments
To make the brownies gluten‑free, use a 1‑to‑1 gluten‑free flour blend. For a vegan version, substitute butter with plant‑based margarine, use flax‑egg replacer (1 tbsp ground flax + 3 tbsp water per egg), and choose a dairy‑free Nutella alternative.
Serving Suggestions
Serve warm with a dollop of whipped coconut cream, a scoop of salted caramel ice cream, or simply dust with cocoa powder and extra sea salt. Pair with a robust espresso or a glass of chilled milk for a balanced dessert experience.
Storage Info
Leftover Storage
Allow the brownies to cool completely, then slice and place them in an airtight container. Store in the refrigerator for up to four days. For longer keeping, wrap individual squares in plastic wrap, place in a freezer‑safe bag, and freeze for up to three months.
Reheating Instructions
Reheat refrigerated brownies in a pre‑heated 300°F oven for 8‑10 minutes, covered with foil to retain moisture. For frozen pieces, thaw overnight in the fridge, then warm using the same oven method. A quick microwave (15‑20 seconds) works for a single serving but may soften the top crust.
