Equipment

Ingredients
 

  • 2 cups Flour
  • 2 teaspoons Baking powder
  • ½ teaspoon Salt
  • ¾ cup Butter, softened
  • 1 ½ cups Brown sugar
  • 2 teaspoons Vanilla
  • 2 Eggs
  • ⅓ cup Hazelnut spread, Nutella

Instructions
 

  • Preheat the oven to 300℉. Butter a 9x9 pan and line the bottom and 2 sides with parchment leaving an inch or two overhang on each side.
  • In a medium size bowl mix together flour, baking powder and salt, set aside.
  • In a large pot over medium heat brown the butter stirring occasionally.
  • Remove from heat, whisk in brown sugar and vanilla.
  • Using an electric mixer whip in eggs. Mix on medium high until light and fluffy. It is important that this mixture is well mixed and the color changes from a darker brown to a lighter tan.
  • Add in the dry ingredients and continue to mix until well mixed and no lumps remain.
  • Evenly spread batter in prepared pan.
  • Dollop hazelnut spread by the spoonful evenly across the surface of the batter. Drag a butter knife through the spread to swirl it through the batter. Drag it through again in the opposite direction to swirl more.
  • Bake for 30-35 minutes in a glass pan, or for 20-25 minutes if using a metal one. The edges will be golden brown and the middle still slightly gooey.
  • Remove from the oven and allow to cool at least 2 hours before cutting. It is normal for the middle to sink below the edges.
  • Cut into 16 squares to serve.

Christina's Notes

  • Use Frozen Nutella: Freeze small scoops of Nutella on a parchment-lined plate before baking to keep gooey pockets intact.
  • Don’t Overmix: Once you add the flour, mix just until combined to keep the blondies tender.
  • Watch the Butter: Brown the butter until golden with a nutty aroma—don’t walk away!
  • Cool Before Cutting: Let the blondies cool fully before slicing for clean edges and the perfect chewy texture.
  • Add a Finishing Touch: A sprinkle of flaky sea salt brings out the rich Nutella and brown butter flavors.
