When I was growing up, anything rainbow meant it was going to be fun. Back in our kitchen, she’d smile and say, “Don’t overmix the colors, let them shine.” Trust me on this. that’s how you keep each shade bright and cheerful. These rainbow no bake cookies are soft, chewy, and full of color without ever turning on the oven.
