Preheat your oven to 350°F (175°C).
Grease a 9x9-inch baking pan or line it with parchment paper.
In a large mixing bowl, combine the flour, oats, brown sugar, baking soda, and salt. Stir until well mixed.
Pour the melted butter into the dry mixture. Stir until crumbly but well combined.
Press about two-thirds of the oat mixture into the bottom of the prepared baking pan.
In a double boiler or microwave-safe bowl, combine the soft caramels and heavy cream. Heat gently until melted and smooth.
Pour the melted caramel over the pressed oat base, spreading it evenly. Sprinkle the chocolate chips over the caramel.
Crumble the remaining oat mixture over the chocolate chips and caramel.
Bake for 25-30 minutes, or until the top is golden brown.
Allow the bars to cool in the pan for at least 15 minutes, then cool completely on a wire rack before cutting into squares.
