  • 1 cup unsalted butter melted & cooled at least 10 minutes (226g)
  • 1 1/4 cups brown sugar packed (250g)
  • 1 1/4 cups Nutella chocolate hazelnut spread (355g)
  • 2 large eggs + 1 egg yolk room temperature
  • 1 1/2 teaspoon vanilla extract
  • 2 1/2 cups all-purpose flour (285g)
  • 2 teaspoons cornstarch (cornflour UK)
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/4 cup additional Nutella chocolate hazelnut spread optional, for topping (70g)


  • Line a 9x9 baking pan with parchment paper and preheat oven to 350F (177C).
  • Combine melted, cooled butter and brown sugar, stir well.  
  • Stir in Nutella until well-combined.
  • Add eggs & egg yolk, one at a time, stirring very well after each addition, then stir in vanilla extract.
  • In a separate, medium-sized bowl, whisk together flour, corn starch, baking powder, and salt.  
  • Gradually stir dry mixture into Nutella mixture until completely combined.
  • Spread into prepared baking pan.
  • With your 1/4 cup Nutella, drop dollops of Nutella over the batter.  Use a butterknife to swirl over the surface.
  • Bake on 350F (177C) for 40-45 minutes (a toothpick inserted in the center of the pan should come out mostly clean with few dry crumbs, don't over-bake or these will be dry!).  Allow to cool before cutting and enjoying.
