About this Recipe
Rice Krispies Trail Mix Bars are the perfect snack or dessert for any time you are on the go. The sweet marshmallows and M&M’s are paired with salty pretzels and peanuts for an amazing sweet and salty flavor combination. You can whip up a whole tray in just 20 minutes and have 12 servings of delicious snacks for your kids for the whole week. Your family will love this gooey, delicious snack! They are best at room temperature because refrigerating them makes them hard to bite into. If you do refrigerate them, make sure to leave them out on the counter until they get soft and chewy again before serving.
Chef’s Note: Having the Kids Help
These Bars are an easy snack that kids can make. Your kids can melt the marshmallow mixture in the microwave (See Method below) if you don’t want them to use the stovetop. There are so many ways to change up this recipe that kids can experiment with their own add-ins and make it their own!
What to Pair With
These snacks are awesome on their own, but you can indulge your sweet tooth by adding a layer of Chocolate Ganache. Refrigerate the bars for 30 minutes before cutting them to allow the ganache to set.
How to Store
- Serve: These Bars can be stored at room temperature in an airtight container for up to 4 days. Make sure to put parchment paper in between layers to prevent them from sticking.
- Store: Refrigerate Bars for up to a week in an airtight container. Serve them at room temperature.
- Freeze: You can freeze Bars for up to 6 weeks in an airtight container.
Microwave Cooking Method
To make Rice Krispies Trail Mix bars in the microwave, add your marshmallows and butter to a large, microwave-safe bowl, and microwave on high for 2 minutes. Stir the butter and marshmallow mixture and put it in the microwave for another minute. Fold in cereal and trail mix until combined and press into a pan.
Variations
- Chocolate chips: Drizzle with melted milk or dark chocolate, or fold in ½ cup chocolate chips. Wait 5 minutes after adding Rice Krispies so the chocolate chips don’t melt.
- Dried Fruit: Swap the raisins with dried cherries or cranberries, depending on your preference and what is in your pantry.
- Nuts and Seeds: Add in your favorite nuts, such as sliced almonds or chopped cashews. You can also add ½ cup of toasted pumpkin seeds.
- Chocolate: Add cocoa powder to the melted butter and marshmallow mixture before stirring it into the cereal.
- Vanilla: Add ½ teaspoon of vanilla extract for added flavor.
- Marshmallows: Fold in ½ cup of mini marshmallows 5 minutes after you add the Rice Krispies so that they don’t melt. You can also try this recipe with Homemade Marshmallows.
