Start by warming up your oven to 175°C (350°F). Get a rectangular 9x13 metal baking pan ready by lining it with aluminum foil and giving it a good coating of non-stick spray.

Using either a stand mixer or a handheld mixer, combine the butter and brown sugar until the blend feels nice and crumbly.
03 -
Toss in the eggs along with the vanilla, and whisk until the batter is beautifully smooth.
04 -
Mix in the salt and baking powder first, and then slowly add the flour. Keep mixing until everything comes together evenly.
05 -
Carefully stir in the candy and sprinkles, making sure they’re spread well in the dough.
06 -
Even out the dough in the pan. If it’s sticky, a quick spritz of spray on your hands will make smoothening it out a lot easier.
07 -
For a little extra flair, sprinkle a handful of extra candy and sprinkles on the top.
08 -
Bake for roughly 22-25 minutes. The sides should look golden. If you want them extra chewy, slightly underbake—let them set as they cool.

Let the tray completely cool down before cutting it into squares. You can keep them fresh in a sealed container or freeze them longer.
