Wholesome Ingredients for This Peanut Butter Granola Bars Recipe

Every element we use in these bars is carefully chosen to nourish your body and keep the recipe simple. Here are the key ingredients that make these easy peanut butter granola bars both delicious and healthy:

• Old-Fashioned Rolled Oats: A fantastic source of fiber and healthy carbs. Choose certified gluten-free oats if needed to meet dietary needs. For added flavor, toast your oats lightly before mixing.
• Natural Peanut Butter: The star ingredient, filled with healthy fats and protein. Opt for a drizzly consistency, or warm it if it’s too thick. For a peanut-free version, use almond butter or sunflower seed butter.
• Honey or Maple Syrup: These natural sweeteners add just the right amount of sweetness while helping to hold the bars together. Honey works best for binding, while maple syrup suits a vegan diet.
• Flax Eggs (for Vegan Option): Ground flaxseed mixed with water creates a plant-based alternative to eggs. It’s easy to make and adds a boost of omega-3s.

How to Make Peanut Butter Granola Bars

1. Preheat your oven to 350°F (175°C).
2. In a large bowl, combine oats, peanut butter, honey or maple syrup, and eggs. *If your peanut butter is thick, heat it for 10-15 seconds to make it drizzly.

4. Transfer the mixture to the dish, and press firmly into an even layer. Pressing well is key to binding!

Peanut Butter Granola Bars FAQs

Can I make these bars without baking?

Yes! For no-bake peanut butter granola bars, skip the eggs and bake step, and refrigerate the mixture until it’s firm, about 1-2 hours.

Are these bars gluten-free?

These can easily be gluten-free by using certified gluten-free oats. Be sure to double-check all packaged ingredients for cross-contamination.

How can I make these bars vegan?

Swap the eggs for flax eggs and use maple syrup instead of honey. The result will still be a flavorful and vegan peanut butter granola bar.

Can I freeze these bars?

Absolutely! Once cut, wrap bars individually in plastic wrap or parchment, then store in an airtight container in the freezer for up to 3 months.

Why aren’t my bars sticking together?

Make sure you’re pressing the mixture firmly into the pan, and let the bars cool fully before cutting. If using maple syrup, try swapping it with honey, which is stickier.
