Hawaiian Rice Krispie Treats

Hawaiian Rice Krispie Treats Variation

This Hawaiian Rice Krispie Treats variation is a gooey, delicious combination of a few inspired recipes by others.

Unsurprisingly, the first is from my mom. She decided to add butterscotch chips to her rice krispie treats a few years ago, which was a very good decision! It’s a surprising one, but somehow it all blends together delectably!

She mixes the chips in with the rice krispies (as opposed to having them on top here). They melt throughout so you get maximum butterscotch in each and every bite.

Since this recipe calls for adding the chips on top, you’ll want to make sure you do it as quickly as possible after you put the marshmallow mixture in the pan. The rice krispies start to cool right away, so you want to get as much of the remaining heat to melt them into the bars!

You might also top it with foil to keep some of the heat in the pan and help melt the chips into the bars.

Mango Glaze

The mango glaze was inspired by that amazing sweet potato recipe roundup we did two weeks ago for the virtual baby shower. It really is so easy to make and I just love the color. I’m sure I’ll be finding more things to top with it – maybe a cake or even a fruit tart!!

Tropical Dessert Recipe

And finally, I learned from my sister to always add vanilla to rice krispie treats – a small but important addition. The macadamia nuts and white chocolate chips fell in because we were heading to a Luau Beach Party. All the flavors screamed magic as I started mixing them together. And so happened the dessert inspiration for these Hawaiian Rice Krispie Treats!

I love adding the familiar flavors of one dish or cuisine to different one. Macadamia nuts and tropical fruit (not just mango) scream Hawaiian flavors. And then I know white chocolate pairs beautifully with macadamia nuts anyway because of macadamia nut cookies.

So while this tropical dessert recipe makes perfect sense, it really is a lofty combination of about 4-6 recipes and flavor combinations!

I should mention… This Hawaiian rice krispie treats variation is on the messy side but totally worth it!

    These look so yummy! Do you think pineapple (or another fruit) purée would work? (mango allergy👎🏼)

    1. Hi lisa! Oh yes, let’s find you an alternative. The mango glaze is really similar to a jam, so you could try any sort of jam or jelly on top, probably. Flavors could include: apricot, pineapple, peach, guava, etc. Were you to try pineapple (I haven’t tried it as I have a sensitivity to pineapple), I’d HIGHLY recommend you drain as much liquid as possible and then make it from there. Please let me know what you try and how it goes!

    1. Hi!! My apologies – I didn’t realize that was missing from the original recipe.

      I just added this to the recipe notes as well. Thank you for the heads up!
