About Homemade Cereal Bars
Simple and easy to customize, these homemade cereal bars aren’t just for breakfast. With a combination of crunchy cereal, your favorite candy, and topped with a drizzle of white chocolate, these bars are the type of snack you’ll want to reach for any time of day.
What is a cereal bar?
To keep it short and sweet, a cereal bar is made with a breakfast cereal that’s been mixed with a sticky coating (most often a marshmallow-based mixture) and compressed into a bar shape. If you’re familiar with Rice Krispies treats, they are a type of cereal bar.
What’s in a cereal bar?
- Breakfast Cereal – Any type of cereal that has small, firm pieces should do the trick. This makes Cheerios a great choice, with Honey Nut Cheerios being the most common. Honeycomb, Lucky Charms, Fruit Loops, Chex, Cinnamon Toast Crunch, and Cap’n Crunch are also good choices.
- Mini Marshmallows and Butter – For making the sticky coating that holds the bars together.
- Semi-Sweet Chocolate Chips – An optional topping, but great for adding more flavor. You can use any flavor, too, from chocolate to butterscotch to white chocolate.
- Candies – Another optional topping, but makes the bars colorful and adds a unique flair. This recipe uses M&M’s, but you can also use chopped snickers, gummy bears, etc – feel free to get creative!
- White Candy Melts – Used for a decorative coating and helps hold the candy toppings in place, but this ingredient is also optional.
What type of candy melts should you use?
Candy melts (also called melting wafters) are pretty common – you can find them in the baking supply area, and they’re small, flat disks, typically sold by the bag – but I do think there are significant differences in quality depending on the brand of candy melts you buy.
Wilton is by far the most common brand of candy melt, and they are sold in a variety of colors. This makes them a popular pick, since you can buy the exact color you need and can get right to crafting your creepy treats. Wilton is simple and easy.
However, I’ve not been impressed with the quality of Wilton candy melts. These candy melts cool fast, which means it becomes thick and harder to use long before you’ve coated all your treats. This leads to them being reheated and the texture and the texture of the melts becomes a little more “iffy” each time.
Given the above, I would highly recommend picking up Ghirardelli brand candy melts instead. These are my favorite candy melts to work with due to the superior quality and taste.
How long are cereal bars good for?
Once prepared, homemade cereal bars can be stored in a sealed container on the counter for up to a week.
Can you freeze cereal bars?
Yes, you totally can!
For best results, wrap each cereal bar with plastic wrap or wax paper and store in an air-tight container or freezer bag.
Cereal bars can be frozen for up to three months.
Notes & tips for homemade cereal bars
- When working with the marshmallow-coated Cheerios it can be useful to grease your hands with butter and use them to mold and press the mixture into the pan.
- If you’d like the candy to be more visible, drizzle the white candy melts first and then top with candy.
