Preheat the oven to 350℉. Line a 9x13-inch pan with parchment paper (hanging over two sides).
In a large bowl, whisk together the butter and two sugars. Then whisk in the beaten eggs, corn syrup and vanilla.
In a separate bowl, sift the dry ingredients together (cocoa powder, flour and salt). Stir the dry ingredients into the wet ingredients. Stir until fully combined.
Scrape the brownie batter into the prepared pan. Smooth the top. Bake for 28 to 32 minutes, just until done and still nice and fudgy. Remove the pan from the oven and let cool completely. Lift the brownies out of the pan (using the parchment paper), and transfer to a cutting board to add the ganache.
ADD THE GANACHE and TOPPING:
Add the chocolate, light corn syrup and salt to a medium glass bowl.
Heat the cream until bubbling in the microwave (or in a small pan on the stove). Pour the hot cream over the chocolate. Let it sit for a minute or two. Then whisk it together until the chocolate is completely melted and nice and smooth. Spread the ganache evenly over the top of the brownies. Sprinkle the candy coated chocolate chips on top. Transfer the brownies to the fridge to chill before cutting.
