Step‑by‑Step Instructions for Customizable 3-Ingredient Homemade Cereal Bars
Step 1: Prepare the Pan
Start by lining an 8-inch square pan with wax or parchment paper, allowing some overhang for easy removal later. This step is essential for ensuring your homemade cereal bars come out intact and easy to slice. Set the prepared pan aside, as you’ll use it once the mixture is ready.
Step 2: Soften the Nut Butter
If your chosen nut butter is too thick to stir, gently warm it in the microwave for about 15-20 seconds until it reaches a creamy consistency. This will help it blend smoothly with the other ingredients. Watch closely to prevent overheating, as you want it warm, not hot when you mix it into your cereal bars.
Step 3: Mix the Ingredients
In a large mixing bowl, combine your cereal of choice, softened nut butter, and your sweetener—agave, honey, or brown rice syrup. Stir vigorously for about 1-2 minutes until everything is well incorporated and you see all cereal pieces coated evenly. The mixture should be sticky and cohesive, ready to press into the pan.
Step 4: Press into the Pan
Transfer the sticky mixture into the prepared pan, spreading it evenly across the bottom. Use a second piece of parchment paper to cover the mixture and press down firmly with your hands or a flat object, ensuring it’s tightly packed to avoid crumbling later. The top should be smooth and uniform; this is key to perfect homemade cereal bars.
Step 5: Chill the Mixture
Place the pan in the freezer for about 30 minutes to set. This will help the bars firm up, making it easier to slice them cleanly. Keep an eye on them; you want them just firm enough to hold their shape but not frozen solid.
Step 6: Slice and Store
Once chilled, remove the cereal bar mixture from the pan using the parchment overhang. Carefully slice into bars, making pieces as large or small as you like. Store your homemade cereal bars in an airtight container—either in the refrigerator for a week or at room temperature for a couple of days, perfect for snacking anytime!

Homemade Easy Cereal Bars Recipe FAQs
What kind of cereal should I use?

How should I store my homemade cereal bars?
Very! To keep your homemade cereal bars fresh and chewy, store them in an airtight container in the refrigerator for up to 1 week. If you prefer room temperature, just make sure they’re kept in a cool, dry spot, and they should stay tasty for a couple of days.
