You will need: - 1 cup unsalted butter - 2 cups granulated sugar - 1 teaspoon pure vanilla extract - 4 large eggs, at room temperature - 1 cup all-purpose flour, spooned and leveled - 1 cup unsweetened cocoa powder - 1/2 teaspoon baking powder - 1/2 teaspoon fine sea salt - 1/2 cup chocolate hazelnut spread (such as Nutella) - 1/2 cup chopped hazelnuts (optional, for added crunch) - Pinch of flaky sea salt for garnish Next, preheat your oven to 350°F (175°C). Prepare a 9x13 inch baking pan. You can grease it with butter or line it with parchment paper. This helps the brownies come out easily later. Now, melt the unsalted butter in a medium saucepan over low heat. Stir it occasionally until it’s fully melted. Once melted, remove the pan from heat. Gradually add the granulated sugar, stirring until smooth. Then, mix in the pure vanilla extract. Add the eggs one at a time. Whisk well after each egg until the mixture looks shiny and combined. In another bowl, sift together the all-purpose flour, unsweetened cocoa powder, baking powder, and fine sea salt. Slowly fold this dry mix into the wet ingredients. Mix until just combined. Be careful not to overmix, or your brownies will be dense. Pour half of the brownie batter into your prepared baking pan. Spread it evenly with a spatula to create a smooth base. Now, dollop the chocolate hazelnut spread over this layer. Take a knife or wooden skewer and swirl it gently into the batter. Aim for a nice marbled look without overdoing it. Next, pour the rest of the brownie batter over the hazelnut layer. Again, swirl in any leftover chocolate hazelnut spread on top. If you like, sprinkle the chopped hazelnuts over the brownies. Finish with a light pinch of flaky sea salt. Now, bake the brownies in the preheated oven for about 25-30 minutes. They are done when a toothpick inserted in the center comes out with a few moist crumbs on it. You want to avoid wet batter. Once baked, let the brownies cool in the pan for at least 10 minutes. After that, lift them out carefully and transfer them to a wire rack. Let them cool completely. For serving, cut the brownies into neat squares. You can use a decorative platter to display them. To make them even more special, drizzle extra chocolate hazelnut spread on top before serving. Enjoy! To get that perfect brownie texture, keep these tips in mind: - Use room temperature eggs. They mix better and create a creamy batter. - Do not overmix the batter. Stir just until combined for a soft, fudgy result. - Bake until a toothpick shows a few moist crumbs. This ensures a gooey inside. Creating beautiful swirls is an art! - Place dollops of chocolate hazelnut spread evenly. This helps with the swirling. - Use a knife or skewer to swirl gently. Too much mixing hides the pattern. - Aim for thick ribbons of hazelnut spread throughout the batter. This adds flavor and looks stunning. Presentation makes your brownies shine! - Cut them into neat squares for a clean look. - Serve on a decorative platter for an inviting display. - Drizzle extra chocolate hazelnut spread on top.

These brownies are fudgy due to the high fat content from butter and chocolate hazelnut spread. Using less flour and more sugar also helps create that rich texture. The key is to mix just enough to combine the ingredients. Overmixing can make them dense instead of soft. Yes, you can swap some ingredients. Use coconut oil instead of butter for a dairy-free option. You can also replace granulated sugar with brown sugar for a deeper flavor. If you need a gluten-free option, try almond flour. These changes can still yield tasty brownies. Check brownies at the 25-minute mark. Insert a toothpick in the center. If it comes out with a few moist crumbs, they are done. If it comes out clean, they might be overbaked. Remember, they will continue to cook a bit while cooling. To make eggless brownies, use applesauce or mashed banana as an egg substitute.

Ingredients
  

1 cup unsalted butter

2 cups granulated sugar

1 teaspoon pure vanilla extract

4 large eggs, at room temperature

1 cup all-purpose flour, spooned and leveled

1 cup unsweetened cocoa powder

1/2 teaspoon baking powder

1/2 teaspoon fine sea salt

1/2 cup chocolate hazelnut spread (such as Nutella)

1/2 cup chopped hazelnuts (optional, for added crunch)

Pinch of flaky sea salt for garnish

Instructions
 

Preheat your oven to 350°F (175°C). Prepare a 9x13 inch baking pan by greasing it well with butter or lining it with parchment paper to ensure easy removal of the brownies later.

    In a medium saucepan over low heat, melt the unsalted butter completely, stirring occasionally. Once melted, remove the saucepan from heat and gradually stir in the granulated sugar until the mixture is smooth and well combined.

      Next, incorporate the pure vanilla extract and add the eggs one at a time, whisking vigorously after each addition until the mixture is glossy and fully incorporated.

        In a separate bowl, sift together the all-purpose flour, unsweetened cocoa powder, baking powder, and fine sea salt. Gradually fold this dry mixture into the wet ingredients, mixing until just combined—be careful not to overmix as this can result in dense brownies.

          Pour half of the brownie batter into the prepared baking pan, spreading it out evenly with a spatula to create a smooth base layer.

            Gently dollop the chocolate hazelnut spread over the brownie base. Using a knife or wooden skewer, swirl it into the batter to create a marbled effect—be sure not to overdo it, as you want to see ribbons of hazelnut spread throughout.

              Carefully pour the remaining brownie batter over the layer of hazelnut spread, repeating the swirling process with any leftover chocolate hazelnut spread on top, again aiming for a beautiful marbled appearance.

                If desired, sprinkle the chopped hazelnuts evenly over the top of the brownies for extra texture, followed by a light pinch of flaky sea salt to enhance the flavors.

                  Bake in the preheated oven for approximately 25-30 minutes. The brownies are done when a toothpick inserted in the center comes out with a few moist crumbs clinging to it (you don’t want it to be wet with batter).

                    Once baked, allow the brownies to cool in the pan for at least 10 minutes before carefully lifting them out and transferring to a wire rack to cool completely.

                        - Presentation Tips: Cut the brownies into neat squares and serve them on a decorative platter. Consider drizzling extra chocolate hazelnut spread over the top before serving for an indulgent touch!
