These lazy chocolate chip cookie bars are gooey, buttery, and packed with chocolate chips. Made in one bowl with pantry staples, they’re the ultimate easy dessert squares for any occasion—no mixer or chilling required.
Let the melted butter cool before mixing with eggs to avoid scrambling. Don’t overmix the batter for the best chewy texture. Start checking for doneness at 22 minutes—bars should be golden at the edges and just set in the center. For perfect squares, chill before slicing. Feel free to customize with your favorite mix-ins like nuts, peanut butter chips, or a swirl of Nutella.
