Ingredients

White Chocolate Blondies

  • 2 cups flour
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp kosher salt
  • 10 tbsp butter melted
  • 2 cups brown sugar packed
  • 2 eggs room temperature
  • 2 tbsp vanilla
  • 1 cup white chocolate chips
  • 1 cup walnuts chopped

Maple Sauce

  • cup maple syrup
  • cup brown sugar packed
  • 4 tbsp butter
  • ½ cup heavy cream
  • 1 tsp vanilla

Instructions

White Chocolate Blondies

  • Preheat oven to 350°F. Line a 9x13 pan with a parchment sling or spray well with baking spray.
  • In a small bowl, whisk the flour, baking powder, baking soda, and salt together. Set aside.
  • In a large bowl, use a handmixer on low speed to combine the melted butter and brown sugar until fully combined, about 30 seconds.
  • Add eggs and vanilla and mix on medium-low speed for 1 minute. Scrape bowl.
  • Add half the flour mixture and mix on low until just combined. Scraped the bowl and repeat with the remaining flour mixture.
  • Add white chocolate chips and walnuts and mix on low until just combined. Don't overmix.
  • Spread batter evenly into prepared pan (the batter will be thick). Bake for 35-40 minutes, until the top is golden brown and a toothpick inserted in the center comes out clean or with moist, fudgy crumbs. Allow to cool fully in the pan.

Maple Sauce

  • While the blondies are baking, make the maple sauce. In a microwave safe dish, combine the maple syrup, brown sugar and butter. Microwave on high for 1.5-2.5 minutes, stirring every 30 seconds until the sugar is fully dissolved.
  • Remove from microwave and add heavy cream and vanilla. Stir to combine. Makes about 1¼ cups of maple sauce.
  • Slice the cooled blondies and serve with vanilla ice cream and maple sauce.

Notes

Tips & Tricks
  • Line the pan with a parchment sling to remove the blondies easily. 
  • Cut the blondies with a sharp knife after refrigerating for the straightest lines. 
  • Vanilla, maple, and white chocolate are the main flavors in the blondies and maple sauce. Use quality, real ingredients for all of them. 
  • Be careful to not overbake. Blondies get very dry when overbaked, so remove them when there are still moist crumbs on the toothpick.
 
Freezer Instructions
Cool completely, then wrap in a layer of plastic wrap and outer layer of tinfoil (alternatively, cut the brownies and store the slices in a zipper bag). Freeze for up to 3 months. Store the sauce in an airtight jar or container (leaving room in the top for expansion) and freeze for up to 3 months.
