Healthy Peanut Butter Granola (Vegan + Naturally Sweetened)

If you keep oats, peanut butter, and maple syrup in your pantry, you’re 20 minutes away from the coziest homemade granola.

This healthy peanut butter granola is lightly sweet, perfectly crunchy, and packed with fiber from ground flax. It smells like cinnamon and vanilla while it bakes — and tastes even better layered over creamy vegan yogurt with fresh fruit.

It’s one of those simple back-pocket recipes that makes weekday mornings feel put together.

And the best part? It’s naturally sweetened with maple syrup, made with pantry staples, and completely vegan.

Why You’ll Love This Peanut Butter Granola

This homemade granola is hearty enough for breakfast, but simple enough to throw together on a Sunday afternoon while the kids are playing and the oven is already warm.

Ingredients You’ll Need

  • 2 ½ cups rolled oats

  • ½ cup natural peanut butter (drippy, unsweetened)

  • ⅓ cup pure maple syrup

  • 1 tablespoon ground flax (for fiber + texture)

  • 1 teaspoon cinnamon

  • 1 teaspoon vanilla extract

  • Pinch of sea salt

That’s it. No refined sugar. No oils. No fillers.

How to Make Peanut Butter Granola

Step 1: Mix

Preheat your oven to 325°F and line a baking sheet with parchment paper.

In a large bowl, stir together the peanut butter, maple syrup, vanilla, cinnamon, and salt until smooth. Fold in the oats and ground flax until everything is evenly coated.

Step 2: Spread

Spread the mixture onto your prepared baking sheet in an even layer. Gently press it down with the back of a spoon — this helps create those big crunchy clusters.

Step 3: Bake

Bake for about 20 minutes, stirring once halfway through.

If you love bigger clusters, stir gently and re-press slightly.

Step 4: Cool Completely

This is key. Let the granola cool fully before breaking it apart. It will crisp up as it cools.

Patience = crunch.

How to Serve Peanut Butter Granola

This vegan peanut butter granola is incredibly versatile:

  • Layered with vanilla yogurt (I’ve been loving Cocojune lately) + fresh berries

  • Sprinkled over smoothie bowls

  • Mixed into overnight oats

  • With almond milk as a cereal

  • By the handful straight from the jar

  • Packed into snack containers for school or car rides

It also makes a beautiful addition to a brunch board or breakfast spread.

Storage Tips

Store in an airtight glass jar or container at room temperature for up to 1 week (though it rarely lasts that long here).

You can also freeze it for longer storage — just let it come to room temperature before serving.

Nutrition Notes

  • Oats provide complex carbohydrates and fiber

  • Ground flax adds omega-3s and additional fiber

  • Peanut butter offers plant-based protein and healthy fats

  • Maple syrup keeps it naturally sweetened without refined sugar

This makes it a balanced vegan breakfast option that keeps you full.

Variations

Want to switch it up?

  • Add chopped peanuts or pecans before baking

  • Stir in mini dark chocolate chips after cooling

  • Mix in shredded coconut

  • Add chia seeds for extra fiber

  • Fold in dried cherries or cranberries after baking

FAQs

Is this peanut butter granola gluten-free?

Yes — just make sure your rolled oats are certified gluten-free.

Can I make this nut-free?

You can substitute sunflower seed butter for a nut-free version.

Why isn’t my granola crunchy?

It likely needs more cooling time. Granola crisps as it cools — don’t skip that step.

The Bottom Line

This healthy peanut butter granola is simple, cozy, and endlessly adaptable. It’s the kind of recipe that makes your kitchen smell warm and inviting — and makes weekday mornings feel easier.
