Preheat the oven to 350 F.

Whisk together the flour, baking powder, baking soda and fine sea salt in a medium sized bowl. Mix in the coconut flakes. Set aside.

Beat the cream cheese until creamy with a mixer (I always prefer the stand mixer). Beat in the sugar and lime zest until completely incorporated.

Scrape the sides and bottom of the bowl. Beat in the melted coconut oil and lime juice. Scrape again.

Beat in the egg.

Using the lowest speed, mix in the flour-coconut flakes mixture into the cream cheese mixture. When it is mostly incorporated, scrape down the sides and bottom of the bowl. Add the chopped macadamia nuts and white chocolate chunks. Continue slowly mixing until everything is evenly incorporated. Do not over-mix.

Line a 9X9 pan with parchment paper. Scrape the dough into the pan and spread it as evenly as possible (it is a pretty thick dough, so do not overthink it, it will even out while baking also).

Bake for 25-30 minutes, or until a cake tester inserted in the center of the pan comes out clean or with melted white chocolate only on it.

Let cool completely in the pan before removing (use the parchment paper) and slicing into bars.
