Follow these straightforward steps to create your Better Than Anything Bars:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease a 9×9-inch baking pan.
2. Mix Dry Ingredients: In a mixing bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt until well blended.
3. Add Wet Ingredients: Stir in melted butter, eggs, and vanilla extract into the dry mixture. Mix until smooth.
4. Fold in Chocolate Chips: Gently fold the chocolate chips into the batter, ensuring they are evenly distributed.
5. Pour into Pan: Pour the batter into the greased baking pan, spreading it evenly.
6. Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
7. Cool: Remove the cake from the oven and let it cool in the pan for 15-20 minutes. Afterward, transfer to a wire rack to cool completely.
8. Prepare Toppings: Once cooled, pour caramel sauce over the top, letting it drizzle down the sides.
9. Spread Whipped Topping: Evenly spread the whipped topping over the caramel layer.
10. Drizzle Chocolate Syrup: Finish with a generous drizzle of chocolate syrup and sprinkle chopped nuts if using.
11. Chill: Place the bars in the refrigerator for at least 30 minutes to set before slicing.
