These amazing easy brownies get their moist and creamy texture from addition of Nutella chocolate spread right in the brownies batter and some extra spread over the top.
Preheat the oven to 350°. Line a 9×9 baking pan with aluminum foil. Spray foil inside with some cooking oil spray.
In a small sauce pot, melt butter over medium heat and whisk in 1 cup of Nutella until all combined and smooth. Take off heat and let it cool for a couple of minutes.
Pour Nutella mixture into a large mixing bowl and whisk in sugar.
Make sure that the mixture is not too hot and add eggs, one at a time, whisking well after each addition. Whisk vigorously for about a minute.
Whisk in the vanilla extract, flour, baking powder, and salt until smooth.
Transfer the mixture into the lined baking pan and spread it evenly.
Warm up remaining 1/2 cup of Nutella and spoon a dollop of Nutella all over the top of brownie mixture. Using a thin spatula, swirl Nutella spread all over the top of the brownie batter in figure 8s. Gently shake the pan a couple of times to make sure batter is all even.
