Cocoa Swirl Walnut Blondies

Ingredients

  • ⅔ cup chopped70 gWalnutscoarsely chopped
  • ½ cup115 gUnsalted buttermelted and slightly cooled
  • ¾ cup packed180 gBrown sugarpacked
  • 2 tbsp25 gGranulated sugar
  • 2 large100 gEggsat room temperature
  • 2 tsp8 gVanilla extract
  • 1¼ cups160 gAll-purpose flour
  • ¾ tsp3 gBaking powder
  • ¼ tsp2 gSalt
  • ¼ cup20 gUnsweetened cocoa powdersifted
  • 1 tbsp (15 ml)15 gMilk, 2%
  • ½ cup80 gSemisweet chocolate chips

Steps

  1. Preheat the oven to 350°F (175°C). Line an 8-inch square pan with parchment, leaving an overhang.
  2. Spread the walnuts on a small baking sheet and toast in the oven for 7–8 minutes until fragrant; let cool.
  3. In a large bowl, whisk the melted butter with the brown sugar and the granulated sugar until glossy, about 1 minute.
  4. Whisk in the eggs one at a time, then the vanilla, until smooth and slightly thickened.
  5. In a separate bowl, whisk the flour, baking powder and salt, then fold this flour mixture into the butter mixture just until no dry streaks remain.
  6. Scoop about one third of the batter into a medium bowl. Stir the unsweetened cocoa powder and the milk into this smaller portion to make a smooth chocolate batter.
  7. Fold the toasted walnuts and the chocolate chips into the remaining two thirds of plain blondie batter.
  8. Spread the walnut blondie batter evenly in the pan. Dollop the chocolate batter over the top in spoonfuls, then drag a butter knife through in figure-eights to marble, without fully mixing.
  9. Bake for 26–30 minutes, until the edges are golden and a toothpick inserted in the center comes out clean.
  10. Cool completely in the pan on a rack, about 1 hour, then lift out with the parchment and cut into 12 bars.
