Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan with butter or non-stick spray.

Melt the butter in a large mixing bowl. Whisk in granulated sugar until the mixture is glossy and well-combined (about 2-3 minutes).

Add the eggs one at a time, ensuring to fully incorporate each before adding the next. Stir in vanilla extract until the batter is smooth.

In a separate bowl, sift together flour, cocoa powder, baking powder, and salt. Gradually mix into the wet mixture until just combined.

Fold in chopped Snickers bars ensuring an even distribution throughout the batter.

Pour the brownie batter into the prepared pan and bake for approximately 30 minutes. Check for doneness with a toothpick.

Allow the brownies to cool in the pan for 10-15 minutes. Drizzle with caramel and sprinkle chopped peanuts and optional chocolate chips.

Once cooled, slice the brownies into squares and serve warm or chilled.
