How to Make Hawaiian Rice Krispie Treats
Step 1: Prepare the Pan
Grease a 9×13-inch baking pan with butter or nonstick spray.

In a large saucepan over low heat, melt the butter until fragrant. Add marshmallows and stir continuously until fully melted and smooth. Mix in the vanilla extract.
Step 3: Add the Cereal
Remove from heat and gently fold in the Rice Krispies cereal until evenly coated. Do not overmix or the treats may become dense.
Step 4: Press into the Pan
Transfer the mixture into the prepared pan. Using lightly greased parchment paper or wax paper, gently press the mixture into an even layer without compacting it too much.
Step 5: Add the Toppings
- Immediately sprinkle:
- Chopped macadamia nuts And White chocolate chips
- Gently press them into the surface.
- Allow the bars to cool completely.
Make the Mango Glaze
- In a bowl, whisk together:
- Mango puree
- Melted butter
- Salt
- Powdered sugar
- Continue mixing until smooth and pourable.
- Drizzle generously over the cooled Rice Krispie treats.
- Let the glaze set for about 20 minutes before slicing.
Tips for the Best Rice Krispie Treats
- Use fresh marshmallows for the softest texture
- Low heat prevents hard treats
- Slightly browning the butter adds caramel flavor
- Don’t press the mixture too firmly into the pan
- Wet your fingers slightly when pressing the bars to prevent sticking
Many modern Rice Krispie recipes recommend browning the butter slightly to create deeper flavor and softer texture.
