Ingredients
All you need to make these delicious cereal bars is:
- Trix Minis cereal
- Jet-Puffed Marshmallows: Buy the original large size, not the jumbo or the mini.
- Butter
Measure the Trix Cereal First
Be sure to measure the cereal before you melt the marshmallows because you don't want the marshmallows to overcook while you measure the cereal after.
This way, you can just pour the cereal in at the right moment.
Prep the Marshmallow Base
Spray a 9 x 13-inch baking pan with cooking spray and set it aside.
Place the measured Trix cereal near the stove next to the open bag of marshmallows.
Add the butter to a large pot that has plenty of room for stirring. Melt it over medium-high heat.
Add the marshmallows to the pot and let them sit a minute.
Gently stir and scrape the bottom of the pot so they don't stick and burn.
Continue to gently stir the marshmallows until they've completely melted and are smooth.
Make the Rice Krispie Treats
Pour in the Trix cereal to the melted marshmallows and stir.
It will be thick and sticky, so be sure to work quickly while the marshmallows are still warm. Things will start to set up quickly.
Pour the entire cereal bar mixture into your prepared baking pan and use a spatula to smooth everything into an even layer.
Use the back of the spatula to gently press the krispie treats into place so that as the cereal bars cool they stick together.
Storage Tips
Let the Trix rice krispie treats completely cool before covering. Keep them at room temperature for up to 5 days.
They taste best within the first 48 hours of making them, and just begin to get quite chewy after that.
Serving Suggestions
These colorful party treats can be cut into generous large squares or cut into small bite-sized squares for a buffet table.
They would be perfect for any rainbow party theme or as an easy St. Patrick's Day dessert for kids.
