Ingredients You’ll Need
- 3 cups Cheerios (or any O-shaped cereal)
- ¾ cup peanut butter (or almond, sunflower seed, or tahini)
- ¾ cup honey (or maple syrup, rice malt syrup, or corn syrup)
- ½ tsp vanilla extract (optional) – for extra flavor depth
- A pinch of salt (optional) – helps balance the sweetness if using natural nut butter
Best Cereals for This Recipe:
Cheerios are classic, but you can also use Rice Krispies, puffed wheat, Shreddies, Multigrain O’s, or fun options like Fruity Pebbles and Lucky Charms for a colorful, kid-approved twist.
These cereal bars are super versatile, and there are so many fun ways to switch things up! You can keep it classic with peanut butter and honey, or mix things up with fun add-ins and themed flavors. Just be sure not to overload the mixture—stick to about ¼ to ½ cup of total extras so the bars still hold together.
Easy Add-Ins
- Dried fruit: Add ¼ cup raisins, chopped dates, dried cranberries, or freeze-dried strawberries for natural sweetness.
- Mini chocolate chips: Stir in 2–3 Tbsp after the peanut butter mixture has cooled slightly so they don’t melt.
- Shredded coconut: Add 2 Tbsp for extra texture and a tropical twist.
- Chia or flax seeds: Sprinkle in 1–2 Tbsp for a boost of fiber and healthy fats.
- Crushed nuts: Try almonds, walnuts, pecans, or even peanut butter chips for added crunch.
- Protein powder: Stir in 1–2 Tbsp of your favorite unsweetened protein powder to make the bars more filling.
Tip: Use natural peanut butter for a slightly less sweet, more wholesome bar.
Common Mistakes to Avoid
Avoid these small slip-ups to get perfectly chewy cereal bars every time:
- Overheating the honey: It burns quickly and can make the bars taste bitter. Use medium-low heat and stir constantly.
- Not pressing the mixture firmly enough: Lightly packed bars won’t hold their shape. Use a spatula or the bottom of a measuring cup to press everything tightly into the pan.
- Skipping the chill time: If you cut them too soon, they’ll fall apart. Chill for at least 1 hour to set properly.
- Too many mix-ins: While add-ins are fun, too many can prevent the bars from sticking together. Keep it simple.
- Using a dry nut butter: Natural nut butters that are too dry or thick may make the bars crumbly. Add 1–2 tsp oil if needed to help with texture.

STEP 2: Mix with cereal
Add 3 cups of Cheerios to a large mixing bowl. Pour the warm mixture overtop and stir until every piece is coated.
STEP 3: Press and chill
