How to Make Your No Bake Cereal Bars
- Melt peanut butter – In a microwave-safe bowl or stovetop, warm the peanut butter until smooth and easy to stir. If using, mix in vanilla, cinnamon, and sweetener.
- Combine dry ingredients – In a large bowl, mix the cereal, hemp hearts, and ground flaxseed.
- Mix & press – Pour the melted peanut butter mixture over the dry ingredients. Stir until evenly coated.
- Shape & chill – Press the mixture firmly into a parchment-lined 8x8-inch pan. Refrigerate for at least 30 minutes until firm.
- Slice & enjoy! – Cut into bars and store as directed below.
Hint
For easier mixing, warm the peanut butter slightly before adding it to the cereal mixture. This helps coat everything evenly and prevents crumbling when shaping the bars! If you're having trouble with it sticking together (make sure to press FIRM), add more nut butter or add liquid sweetener.
Substitutions for No Bake Cereal Bars
- peanut butter - almond butter, cashew butter, sunflower seed butter, or tahini for a nut-free option
- cereal - swap for rolled oats, puffed rice, or granola for a different texture
- hemp hearts - replace with chia seeds, or extra flaxseed for a similar nutrient boost
- ground flaxseed - use chia seeds or wheat germ for added fiber and omega-3s
- sweetener - skip or reduce honey/maple syrup for less sweetness, or swap for date syrup or mashed banana
This is so easy to customize and make your own!
Variations
- chocolate lover’s – mix in mini chocolate chips or drizzle melted dark chocolate over the top
- berry boost – stir in freeze-dried or finely chopped dried fruit like strawberries or blueberries
- crunchy delight – add chopped nuts, coconut flakes, or crushed pretzels for extra texture
- protein-packed – stir in 1-2 scoops of protein powder to boost the protein content (will need to add more nut butter)
Equipment
All you will need is a mixing bowl and square dish! If you prefer to pop out, here is a silicone dish you can use.
Storing Your No Bake Cereal Bars

Tiff's Dietitian Tip
Get your little one's involved in making these! The more they're included in the process, the more likely they're going to try a bite. These make such a great breakfast, snack, or lunchbox addition (just use sunbutter in place of peanut butter).
FAQ
