Tropical Magic Bar Cookies

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.

Tropical Magic Bar Cookies


  • 2 cups graham cracker crumbs
  • 1/4 cup sugar
  • 1/2 cup butter, melted
  • 1 can (14 oz.) sweetened condensed milk
  • finely grated lime zest from two limes
  • 1 cup diced macadamia nuts
  • 2/3 cup white chocolate chips
  • 2/3 cup Coconut M&M’s
  • 1 1/4 cup sweetened shredded coconut


Preheat oven to 350º.

In a large bowl combine graham cracker crumbs and sugar. Add butter and toss until combined. Press into the bottom of a 9 x 13 baking pan coated with cooking spray.

Bake until firm, approximately 10 minutes. Cool on a wire rack for approximately 20 minutes.

In a small bowl, combine sweetened condensed milk and lime zest. Set aside.

When crust is cooled, top with macadamia nuts, white chocolate chips and M&Ms. Pour condensed milk over the top, spreading to cover completely. Sprinkle coconut evenly on top of condensed milk.

Bake until coconut is toasted, 10 to 15 minutes. Transfer to rack to cool completely before cutting.

    I haven’t had one of these since I left the states. No graham crackers here but I’ve learned of a make-do so I’ll give these a try. They look perfectly tropical. It’s summer here so very fitting indeed.

    This is the best twist I’ve seen on a classic cookie bar. This is why I am dying for your cookbook…so I can just order it and open it up in my kitchen when baking or cooking so many of your beautiful and creative treats!

    Coconut m&m’s??Coconut m&m’s?!? Oh man – we can’t get those in Australia. I come to these lovely American blogs and am astounded at the range of things you can get that we can’t! But, never fear, I think it’ll work with normal m&m’s too :)

    Lime–what an awesome twist! We’re all huge fans of magic cookie bars over here, and this tropical twist (in the middle of autumn!) is absolutely perfect. Thank you for sharing, Barbara!
