Tropical Magic Bar Cookies

An easy to put together bar cookie with a tropical twist. A graham cracker crumb crust topped with layers of white chocolate chips, Coconut M&M’s, macadamia nuts, shredded coconut, and a sweet gooey lime filling.

Magic Cookie Bars, 7 Layer Bars, Hello Dolly Bars what ever you like to call them, are a very popular bar cookie. You can even find the recipe on the back of sweetened condensed milk cans and boxes of graham cracker crumbs. I decided to change up this sinfully rich, ooey, gooey treat and give it a tropical flare with a little lime zest, macadamia nuts and Coconut M&Ms.


I added the zest of two limes to the sweetened condensed milk and the lime flavor is a perfect match for the chocolate, nuts and coconut. I made the bars with coconut oil, but the crust didn’t set up as firmly as if I’d used butter, so I put butter in the recipe below. If you love citrus desserts and magic bars, you’re going to love this version.

Yield: 16 bar cookies
