Ingredients
  • 1 cup (250 ml) salted butter, melted
  • 1 cup (200 g) brown sugar, packed
  • ½ cup (113 g) granulated sugar
  • 2 eggs + 1 egg yolk
  • 1 tbsp.(14.7 ml) vanilla extract
  • 12/3 cups (224 g) all-purpose flour
  • 1 tsp. (5 g) baking soda
  • pinch salt
  • 1 tsp. (5 g) ground cinnamon
  • 2 cups (180 g) oatmeal (quick cooking or rolled)
  • 1¼ cups (170 g) chocolate chips (or chopped chocolate, chocolate candies, etc)
  • Optional toffee chips, nuts, etc.
Method
  1. Preheat the barbecue to 350°F (177°C), preparing to use indirect grilling method by only lighting the outside two burners to low or a single burner to medium.
  2. Prepare a 9x13 inch (23 x 33 cm) baking dish by lining it with parchment or spraying it with nonstick.
  3. Whisk together the melted butter and sugars, stir in the vanilla and then beat in the eggs and yolk. 
  4. Sift the flour, baking soda, salt, and cinnamon over the butter mix and then add the oatmeal. Fold it all together until barely mixed. Gently fold in the chocolate/mix-ins.
  5. Bake the cookie bars on the barbecue making sure to place the baking dish over the burners that are not lit. if you only have one burner ignited, you will want to turn the baking dish halfway through to ensure even baking.
  6. Bake the oatmeal chocolate cookie bars for about 25 minutes or until the edges are golden crisp and the center appears mostly set. Weather and altitude may change times a little so keep an eye on things, but only open the lid on your barbecue once or twice because lookin’ ain’t cookin’. 
  7. Remove from the barbecue using heat-resistant barbecue gloves and allow to cool for about 10 to 15 minutes before slicing and serving.
