Wholesome Ingredients for These Healthy Peanut Butter Snack Bars

We’re keeping things simple with just three ingredients, yet each one plays an important role in the recipe:

• Peanut Butter: This is the star of these bars, bringing protein, healthy fats, and that creamy, nutty flavor. We recommend using unsalted peanut butter made with just peanuts (and maybe a pinch of salt). If you’re avoiding peanuts, almond or sunflower seed butter works too!
• Honey: For natural sweetness, honey does the trick while helping to bind the bars. If you’d prefer a vegan option, maple syrup is a great substitute. Just note that the texture may be slightly softer.
• Cheerios: The base for these bars, Cheerios add crunch and are a great source of whole grains. Make sure to use plain Cheerios for the healthiest option free of added sugars or flavors.

How to Make Peanut Butter Cheerio Bars

1. Prepare your dish: Line an 8×8 or 9×9 square baking dish with parchment paper to prevent sticking and make cleanup easy.
2. Melt the mixture: Combine the peanut butter and honey in a microwave-safe bowl. Heat them in the microwave for 30 seconds, then stir until smooth and fully combined. You can also melt them on the stovetop over low heat if you prefer.
3. Mix in the Cheerios: Pour the Cheerios into the melted peanut butter and honey mixture. Stir gently until all the cereal pieces are evenly coated.
4. Shape the bars: Transfer the mixture into your prepared dish, spreading it out evenly and pressing down with a spatula to compact the bars.
5. Chill to set: Place the dish in the refrigerator for about 1 hour, or until the bars are firm and set.
6. Slice and enjoy: Once the bars have hardened, lift them out of the dish using the parchment paper and slice into 9 even squares. Store in an airtight container in the refrigerator for up to a week.

How to Customize These Peanut Butter Cheerio Bars for Your Diet

• Nut-free: Swap the peanut butter for sunflower seed butter to accommodate allergies.
• Vegan: Use maple syrup instead of honey as the sweetener.
• Lower calorie: Experiment with powdered peanut butter reconstituted with water, though the bars may be softer.
• Higher protein: Stir in a scoop of your favorite unsweetened protein powder when mixing the Cheerios.
• Customized flavors: Add a sprinkle of cinnamon, a handful of raisins, or mini dark chocolate chips to change up the taste.

Our Team’s Tips for the Best No-Bake Cheerios Bars

• Use fresh honey and peanut butter for the best consistency and flavor. If your peanut butter is too thick, warm it slightly before mixing.
• Press the mixture firmly into the pan to help the bars hold together better.
• Chill for at least an hour to ensure the bars set properly. For quicker chilling, you can use the freezer for 20–30 minutes instead.
• Cut the bars with a sharp knife for clean edges. Warming the knife slightly can make slicing even easier.
• Store in a cool place or fridge, as they soften at room temperature due to the natural peanut butter and honey.
