Ingredients Needed

Labeled ingredients on a table to make peanut butter granola.
  • Oats: I’ve tested this recipe with rolled oats, old-fashioned oats, quick oats, and even a combination of all three. They all work well, so use what you have on hand. If you’re gluten-free, be sure to use certified gluten-free oats.
  • Peanut Butter: Use a natural, drippy peanut butter for the best flavor and texture. It helps coat the oats evenly and creates those irresistible crunchy clusters. You can even use my homemade peanut butter!
  • Chia Seeds: Add fiber, omega-3s, and a little extra crunch.
  • Ground Flaxseed: Adds extra nutrients and helps bind the granola together.
  • Cinnamon + Salt: Enhances the peanut butter flavor and makes every bite taste a little more like a peanut butter cookie.
  • Coconut Sugar: A refined sugar-free sweetener that adds caramel-like sweetness.
  • Maple Syrup: Naturally sweetens the granola and helps create those big clusters, just like in my healthy chocolate granola.
  • Coconut Oil: Helps the granola bake up golden and crispy. I recommend using refined coconut oil if you don’t want any coconut flavor.
  • Vanilla Extract: Adds warmth and brings all the flavors together.

Substitutions & Variations

  • Maple Syrup: Swap with agave. Honey also works, but it will make the recipe non-vegan.
  • Peanut Butter: Swap for almond butter or cashew butter for a slightly different flavor.
  • Nut-Free Option: Replace the peanut butter with sunflower seed butter for a nut-free granola.
  • Crunchy Peanut Butter: I’ve tested this version a few times, and it’s delicious! It adds even more peanut flavor and crunchy bits throughout.
  • Chopped Peanuts: Stir in 1/2 cup chopped peanuts before baking for extra crunch and peanut butter flavor.
  • Chocolate Chips: Once the granola has completely cooled, mix in 1/2 cup chocolate chips for a peanut butter cup-inspired granola.

Megan’s Tips

  • For big crunchy clusters: Press the granola firmly into the baking pan before baking. Once it’s out of the oven, resist the urge to stir it! Let it cool completely, then break it into clusters with your hands. That’s my secret for getting those big crunchy clusters.
  • Use a runny peanut butter: A natural, drippy peanut butter works best because it coats the oats evenly. If your peanut butter is thick, microwave it for 15–20 seconds to loosen it up before mixing.
  • Let it cool completely: I know it’s tempting to dig in right away, but cooling is what creates the best texture and crunch.

Serving Suggestions

Here are some of my favorite ways to enjoy this peanut butter granola:

  • On yogurt: Sprinkle over your favorite dairy-free yogurt with berries for a quick breakfast.
  • On smoothie bowls: Sprinkle it on my raspberry smoothie bowl or vegan açaí bowl.
  • With milk: Enjoy as a cold cereal with your favorite milk.
  • As a snack: Grab a handful of these chunky clusters straight from the jar!

Peanut Butter Granola FAQs

Can I reduce the amount of sugar?

This peanut butter granola isn’t super sweet, but you can reduce the amount of coconut sugar if you want. Just don’t change the maple syrup since it helps bind the ingredients together to get those clusters.

How do I get big granola clusters?

My trick is to press the granola mixture into the baking pan before baking. After baking, let it cool completely without stirring. Once cooled, break it into clusters with your hands. You’ll have large, crunchy clusters!

Why isn’t my granola crunchy?

The most common reason is not letting it cool completely. Granola continues to crisp up as it cools. For extra crunchy clusters, press the mixture firmly into the pan before baking.

Can I make this granola nut-free?

Absolutely. Swap the peanut butter for sunflower seed butter for a nut-free version.

What type of oats work best for homemade granola?

I’ve tested this peanut butter granola recipe with rolled oats, old-fashioned oats, quick oats, and a combination of all three. They all work well, although I’ve found that quick oats tend to create the crunchiest texture.

How long does homemade peanut butter granola last?

Store the peanut butter granola in an airtight container at room temperature for up to 2 weeks. For longer storage, freeze it for up to 3 months.

Homemade Peanut Butter Granola (Vegan, Gluten-Free)

This homemade peanut butter granola recipe tastes like a peanut butter cookie, with big crunchy clusters and rich peanut butter flavor. Easy to make, vegan, gluten-free, and ready in 30 minutes!

Ingredients
 

wet ingredients

dry ingredients

  • 2 ½ cups oats, rolled or quick, use gf oats if needed
  • 1 tablespoon chia seeds
  • 1 tablespoon ground flaxseed
  • ½ teaspoon cinnamon
  • ¼ teaspoon salt

Instructions
 

  • Preheat the oven: Set the oven to 325°F and line a large baking sheet with parchment paper.
  • Whisk the wet ingredients: In a large bowl, whisk together the peanut butter, melted coconut oil, maple syrup, coconut sugar, and vanilla extract until smooth.
  • Mix in the dry ingredients: Stir in the oats, chia seeds, ground flaxseed, cinnamon, and salt. Mix well to coat everything evenly.
  • Bake: Transfer the mixture to your prepared baking sheet. Press it down gently with a spatula (this will help form those crunchy clusters!). Bake for 20-25 minutes, or until golden.
  • Cool completely: Once out of the oven, let the granola cool completely on the pan without stirring (this can take anywhere from 20-30 minutes). This step is key to getting those big, crunchy clusters! Once it's cool, then you can break it into chunks and enjoy!

Notes

  • For big clusters: Press the granola firmly into the pan before baking and don’t stir it. Once it’s out of the oven and fully cooled, break it apart with your hands; that’s how you get those giant, crunchy clusters!
  • Use a runny peanut butter: Opt for an all-natural, runny peanut butter. If your peanut butter is thick, microwave it for 15–20 seconds to loosen it up; this helps coat the oats evenly.
  • Adjust the sweetness: While this granola isn’t overly sweet, you can reduce the coconut sugar slightly. Just keep the maple syrup since it helps bind everything together to get those clusters.
  • Storage: Store your granola in an airtight glass jar or container at room temperature for 2 weeks, or freeze for up to 2 months. If it ever softens, spread it on a baking sheet and re-crisp it in the oven at 300°F for 5–7 minutes.
