Nutella Blondies

Directions

1. 1
   Preheat the oven to 325 degrees.
2. 2
   Line a 7x11 pan with parchment paper.
3. 3
   In a pan, melt all the butter over medium heat, taking care that it doesn't burn. Set aside to cool slightly.
4. 4
   In a mixing bowl, stir together the eggs, demerara sugar, and granulated sugar.
5. 5
   Stir in the melted butter, salt, vanilla, flour, baking soda, and baking powder. (Mixture will be quite thick.).
6. 6
   Spoon the batter into the prepared pan in an even layer.
7. 7
   Dollop the Nutella over the surface of the batter, and swirl the tip of a knife in the Nutella to get a pretty, freestyle pattern.
8. 8
   Bake for 25-30 minutes, checking frequently to make sure the blondies don't overbake.
9. 9
   The blondies are done when the batter is puffed and golden, and is still a little moist in the middle.
10. 10
    The blondies will collapse slightly once they come out of the oven, and will harden into slice-able pieces in about an hour.
