Ingredients:

  • 1/2 cup (113g) unsalted butter, browned
  • 1 cup (200g) light brown sugar, packed
  • 1 large egg (50g)
  • 1 tsp (5ml) vanilla extract
  • 1 cup (125g) all-purpose flour
  • 1/4 tsp (1.5g) salt
  • 3/4 cup (125g) semi-sweet chocolate chips
  • 8 oz (225g) full-fat cream cheese, softened to room temperature
  • 1/4 cup (50g) granulated sugar
  • 1 large egg (50g)
  • 1/2 tsp (2.5ml) vanilla extract

Instructions:

  1. Brown the butter: Place butter in a saucepan over medium heat. Melt and continue cooking, whisking constantly, until the butter foams and small brown specks appear at the bottom. Remove from heat immediately.
  2. Cream the sugars: In a large bowl, combine the browned butter and brown sugar. Whisk in one egg and 1 tsp vanilla extract until the mixture looks glossy and smooth.
  3. Fold in dry ingredients: Sift in the flour and salt. Using a spatula, fold gently until just combined. Stir in the chocolate chips.
  4. Pan Prep: Line an 8x8 inch baking pan with parchment paper and spread the blondie batter evenly across the bottom.
  5. Cream the cheese: In a separate bowl, beat the softened cream cheese and granulated sugar until completely smooth.
  6. Emulsify cheesecake layer: Add the second egg and 1/2 tsp vanilla extract. Beat on medium-high until the mixture is velvety and pale.
  7. Layer and swirl: Dollop the cheesecake mixture over the blondie batter. Use a butter knife or skewer to gently swirl the two batters together in a figure-eight motion.
  8. Bake: Bake at 350°F (175°C) for 30–35 minutes until the edges are golden brown and the center remains slightly jiggly.
  9. Cool: Allow the bars to cool completely in the pan for at least 1 hour before lifting out via parchment paper and slicing.
