Why I Love This Recipe
Halloween is a great time to get creative with treats, and these Ube Halloween Rice Krispie Treats are both easy and fun. They’re perfect for parties, school events, or bringing to the office. The bright purple color from the ube extract turns an ordinary snack into something special that’s sure to get compliments.
What is Ube?
Ube is a purple sweet potato from the Philippines with a subtly nutty, vanilla-like flavor. It’s commonly used in Filipino breads and desserts and has become more popular worldwide because of its vibrant color and unique taste. Ube is different from taro, which is a white root vegetable; any confusion likely comes from taro’s tendency to take on a slight purple tint when cooked.
How to Make Ube Rice Krispie Treats
Lightly coat a 10×8 or 9×13 pan with non-stick spray. In a large pot over medium heat, melt 3 tablespoons of butter completely. Once melted, add 4 cups of mini marshmallows and stir constantly until the marshmallows are fully melted and smooth. Remove the pot from the heat right away.
Stir in 1 teaspoon of ube extract until the color and flavor are evenly distributed. Quickly add 6 cups of puffed rice cereal and fold until the cereal is coated evenly with the marshmallow mixture.
Transfer the mixture into the prepared pan and press it down firmly with a spoon. Lightly spray your hands with non-stick spray and press the mixture to compact it evenly—take care, as it may still be hot. Generously sprinkle Halloween-themed sprinkles on top and press them in so they adhere.
Let the treats cool for at least 20 minutes before slicing. For firmer bars and cleaner cuts, you can chill them briefly before cutting. Serve and enjoy.

Expert Tips for Making the Best Rice Krispie Treats
- Press the mixture firmly into the pan so the treats hold together. Spraying your hands with non-stick spray helps keep things neat—hot marshmallow is extremely sticky.
- Allow the treats to cool completely before cutting. Refrigerating them for a short time will make slicing easier.
- Store leftovers in an airtight container at room temperature for 2–3 days to keep them fresh.
- Use any sprinkles you like. If you want specialty pieces (like candy eyeballs), add them separately to get the look you want.
- Soak the pot and spoon in hot water after use; the marshmallow residue will come off easily.
- Toy spiders or other decorations are fun for presentation—just be sure they aren’t mistaken for edible items.

-
non-stick spray
Ingredients
- 3 tablespoons butter
- 4 cups mini marshmallows
- 6 cups puffed rice cereal
- 1 teaspoon ube extract

Instructions
- Prepare a pan with non-stick spray. A 10×8 pan makes thicker bars; a 9×13 works for thinner bars. Glass pans tend to stick less and clean more easily.

- Add the marshmallows and stir constantly until completely melted and creamy. Remove from heat immediately.
- Stir in the ube extract until evenly combined with the marshmallow mixture.
- Fold in the puffed rice cereal quickly until the cereal is fully coated. Transfer the mixture to the prepared pan and press down with a spoon. Lightly spray your hands and press to compact the mixture—be careful, it will be hot.
- Top with sprinkles and press them in so they stick. Let cool at least 20 minutes before cutting and serving. Enjoy!
Notes
- Press the treats firmly into the pan so they hold together well; spraying your hands helps reduce stickiness.
- Cool completely before slicing. Chilling briefly makes cutting neater.
- Store leftovers in a covered container for 2–3 days.
- Swap in any sprinkles you prefer. Add specialty decorations separately if needed.
- Soak utensils in hot water for easy cleanup.
- Use non-edible decorations like toy spiders for display, but remove them before serving.
