These deliciously fudgy, moist Key Lime Brownies are swirled with rich key lime cheesecake filling and topped with cream cheese frosting. What's not to love!
Preheat oven to 325 degrees. Lightly spray a 8x8-inch square baking dish with a nonstick spray.
When cool (I suggest putting it in the refrigerator for about 1 hour), either frost entire top or turn out onto wooden cutting board and cut into 16 squares, then frost each one. (Easiest to do if you run a sharp knife under very hot water, cut, wipe off blade, then cut again)
Decorate by either frosting the entire top or, using a decorator's kit with tips, cut into squares and pipe a little on top of each cut brownie.
