Soft and Chewy Chocolate Chip

This is the best Soft and Chewy Chocolate Chip Blondie ever and I am here for all the chocolate chips and the sprinkle of sea salt. Made with melted butter, cornstarch for a super soft texture, semi sweet chocolate chips and milk chocolate chips, you are in for a perfect salty and sweet treat.

  • 2 ¼ Cups All Purpose Flour
  • 1 Teaspoon Baking Soda

  • 1 Egg
  • 1 Egg Yolk
  • 1 Teaspoon Vanilla Extract
  • 1 Cup Semisweet Chocolate Chips
  • 1 Cup Milk Chocolate Chips

  • Preheat oven to 350 degrees F and prepare a 9x9 inch square cake pan with non stick spray and lined with parchment paper
  • In a medium bowl combine the flour, baking soda, cornstarch and salt; set aside
  • In a mixing bowl with paddle attachment, combine the melted butter and light brown sugar; mix on medium speed until creamy and fully combined

  • Add the flour mixture into the butter mixture and mix on medium speed until the dough comes together
