Ingredients

  • Cheerios or any O’s cereal
  • peanut butter or nut/seed butter of choice
  • hemp hearts
  • ground flaxseed
  • honey or maple syrup (optional)

See recipe card for quantities.

Instructions

  1. 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.
  2. Combine dry ingredients – In a large bowl, mix the cereal, hemp hearts, and ground flaxseed.
  3. Mix & press – Pour the melted peanut butter mixture over the dry ingredients. Stir until evenly coated.
  4. Shape & chill – Press the mixture firmly into a parchment-lined 8×8-inch pan. Refrigerate for at least 30 minutes until firm.
  5. 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

  • 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.

Storage

Refrigerator: Store in an airtight container for up to 1 week.

Freezer: Wrap individual bars and freeze for up to 3 months. Thaw in the fridge or at room temp before eating.

Tiff Tip

Press the mixture firmly into the pan! This helps the bars hold together better and prevents them from crumbling when sliced. Use a spatula or the bottom of a measuring cup to compact them evenly.

FAQ

Can I make these cereal bars nut-free?

Yes! Swap peanut butter for sunflower seed butter or tahini for an allergy-friendly option.

Why are my bars falling apart?

Make sure the peanut butter is fully melted and well mixed. Also, pressing the mixture firmly into the pan and chilling long enough will help them hold together.

Can I add mix-ins to these bars?

Absolutely! Try adding mini chocolate chips, dried fruit, or shredded coconut for extra flavor and texture.
