09 - 165g all-purpose flour
10 - 0.5 teaspoon baking powder
11 - 0.5 teaspoon kosher salt
12 - 110g unsalted butter, room temperature

18 - 95g walnuts or pecans, finely chopped

# Instructions:

01 - Ensure all caramel ingredients, especially the heavy cream, are ready and at room temperature before starting. Warm heavy cream if necessary in the microwave to avoid seizing.
02 - Add water and sugar to a heavy-bottomed saucepan. Stir carefully to combine without splashing sugar onto the sides. Heat over medium heat and let the sugar dissolve.
03 - Once the sugar is clear and bubbling, watch as it changes color from clear to amber. Stir gently to even out uneven browning, then remove from heat.
04 - Immediately whisk in the butter, followed by slowly pouring in the heavy cream while whisking. Mix in vanilla and salt, bubble for 2 minutes, and stir in flour.
05 - Preheat oven to 175°C (350°F). Grease and line all sides of an 8×8 baking dish with parchment paper.
06 - In a medium bowl, mix oats, flour, baking powder, and salt. Set aside.
07 - In a large mixing bowl, combine softened butter and dark brown sugar until smooth. Mix in egg, egg yolk, and vanilla.
08 - Add dry ingredients to wet ingredients and mix until combined. Stir in 85g semisweet chocolate chips before the flour is fully blended.
09 - Spread 2/3 of the dough in the baking dish, sprinkle the layer with nuts, and bake for 8 minutes. Chill remaining dough in the refrigerator.
10 - Once the crust is baked, evenly distribute dark chocolate chips over the crust. Pour over the caramel, reheating briefly if it has thickened too much.
11 - Add blobs of remaining cookie dough on top. Bake for 20–25 minutes or until lightly golden. Cool for 30 minutes at room temperature, then chill for 1 hour.
12 - Use a knife to loosen edges if needed before removing the bars from the pan. Sprinkle with sea salt, slice, and serve.
