Description

These Gooey Chocolate Chip Cookie Bars are a rich, buttery treat loaded with chocolate chips and a creamy condensed milk layer, all wrapped in a soft, chewy cookie base with golden, crisped edges.


Ingredients

Scale
  • 1 cup (226 g) unsalted butter, melted
  • 3/4 cup (150 g) granulated sugar
  • 1 cup (200 g) packed brown sugar
  • 2 large eggs
  • 1 tsp pure vanilla extract
  • 1 tsp baking soda
  • 3 cups (372 g) all-purpose flour
  • 1/2 tsp salt
  • 1 1/2 cups (255 g) chocolate chips
  • 1 (14 oz) can sweetened condensed milk
  • 1 (4.4 oz) Hershey bar or equivalent chocolate, broken into pieces

Instructions

  1. In a saucepan over medium heat, brown the butter, stirring frequently until it turns a light golden brown. Remove from heat and let cool for 5 minutes.
  2. Stir in the granulated sugar and brown sugar until combined. Let the mixture cool slightly.
  3. In a separate bowl, whisk together flour, baking soda, and salt.
  4. Beat the eggs into the butter-sugar mixture one at a time, then add vanilla extract.
  5. Gradually mix in the dry ingredients until just combined.
  6. Fold in the chocolate chips.
  7. Line a 9×13-inch baking pan with foil and lightly grease or spray.
  8. Press half of the cookie dough evenly into the bottom of the prepared pan.
  9. Pour the sweetened condensed milk evenly over the dough layer.
  10. Scatter the chocolate bar pieces over the condensed milk.
  11. Drop spoonfuls of the remaining dough on top and gently press to spread out and cover the filling.
  12. Bake at 350°F (175°C) for 30–35 minutes or until golden brown and set in the center.
  13. Allow the bars to cool completely in the pan before slicing.

Notes

  • Chill before slicing for cleaner cuts.
  • You can substitute semi-sweet chocolate chips or dark chocolate if preferred.
  • Use parchment or foil to lift the bars easily from the pan.
  • Store bars in an airtight container at room temperature for up to 5 days.
