Ingredients
  • 320g plain flour
  • 1 tsp baking soda
  • 1 tsp fine sea salt
  • 230g unsalted butter, melted and slightly cooled
  • 200g light brown sugar
  • 100g caster sugar
  • 2 large large eggs, room temperature
  • 2 tsp pure vanilla extract
  • 350g semi-sweet chocolate chips
  • 1 tsp flaky sea salt for sprinkling
  • 1 litre vanilla ice cream, for serving
  • 250ml chocolate sauce, for serving
  • 250ml caramel sauce, for serving
  • 250ml whipped cream, for serving
  • 12 maraschino cherries, for serving
Instructions
  1. Preheat oven to 180°C (350°F). Line a 23x33cm (9x13 inch) baking pan with parchment paper, leaving overhang for easy removal.

  2. In a medium bowl, whisk together 320g plain flour, 1 tsp baking soda, and 1 tsp fine sea salt. Set aside.

  3. In a large bowl, whisk together the melted 230g unsalted butter, 200g light brown sugar, and 100g caster sugar until well combined and smooth.

  4. Beat in 2 large large eggs one at a time, then stir in 2 tsp pure vanilla extract until fully incorporated.

  5. Gradually fold in the flour mixture until just combined - don't overmix. The dough will be thick and slightly sticky.

  6. Fold in 350g semi-sweet chocolate chips, distributing them evenly throughout the dough.

  7. Press the cookie dough evenly into the prepared baking pan using your hands or an offset spatula. The layer should be uniform and reach all corners.

  8. Sprinkle the top evenly with 1 tsp flaky sea salt for sprinkling.

  9. Bake for 22-25 minutes, until the edges are set and lightly golden but the center still looks slightly underbaked. The bars will continue cooking from residual heat.

  10. Cool completely in the pan before cutting into 12 squares using the parchment overhang to lift out.

  11. To serve as sundae bars, place each cookie square on a plate, top with a scoop of 1 litre vanilla ice cream, and provide 250ml chocolate sauce, 250ml caramel sauce, 250ml whipped cream, and 12 maraschino cherries for guests to build their own sundaes.

Tips

Perfect Texture: The key to chewy bars is not overbaking - they should look slightly underdone in the center when you remove them from the oven.

Butter Temperature: Make sure melted butter has cooled slightly before adding to prevent the eggs from cooking when mixed.

Even Distribution: Press the dough firmly and evenly into the pan to ensure uniform baking and neat squares when cut.

Storage: Store unfrosted bars covered at room temperature for up to 5 days, or freeze for up to 3 months.

Sundae Station: Set up a sundae bar with various toppings like crushed cookies, nuts, sprinkles, fresh berries, and different ice cream flavors for a fun party dessert.

Make-Ahead: Bars can be baked 1-2 days in advance. Store covered and cut just before serving for the freshest edges.

Cutting Tips: Use a sharp knife and wipe it clean between cuts for neat squares. Chilling the bars for 30 minutes before cutting also helps with clean lines.
