Creating these Sea Salt Caramel Bars is a straightforward process. Follow these steps to ensure success:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
2. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract until well combined.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt.
5. Mix Wet and Dry Ingredients: Gradually add the dry ingredients to the butter mixture, mixing until just combined. Do not overmix.
6. Spread Batter: Pour half of the batter into the prepared baking pan, spreading it evenly across the bottom.
7. Add Caramel Sauce: Drizzle the caramel sauce over the batter, leaving a small border around the edges.
8. Top with Remaining Batter: Spoon the remaining batter over the caramel layer, spreading it gently to cover as much as possible.
9. Bake: Place the pan in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
10. Cool and Sprinkle Salt: Remove from the oven and allow the bars to cool in the pan for about 20 minutes. Once cooled, sprinkle the sea salt on top.
11. Cut into Bars: Once completely cooled, cut into squares or rectangles for serving.
