It's impossible to not smile when you gaze at these out-of-this-world treats. This is a blondie riff on the classic American grocery store treat, Cosmic Brownies, with a marbled galaxy-like topping. Brown butter and a good bit of salt are the backbone of this recipe's base, which comes together in minutes and is extremely customizable. Try adding any of your favorite mix-ins, such as toasted nuts or sprinkles. The swirled ganache topping may look intimidating, but with a spatula and a bit of confidence, it's very easy to achieve something striking. Make sure to choose a mix of colors that look nice when they run together, and most importantly, make sure to have fun while swirling them.
