Ingredients and Simple Swaps

• 2 cups quick-cooking oats
• ½ teaspoon ground cinnamon
• ¼ teaspoon sea salt
• 6 Tablespoons creamy peanut butter
• ¼ cup honey (or maple syrup)
• ½ teaspoon pure vanilla extract

Bake and Mix Instructions

1. Preheat oven to 325°F and lightly grease a large baking sheet (or line with parchment).
2. Stir together quick-cooking oats, sea salt, and ground cinnamon in a small bowl.
3. Melt creamy peanut butter and honey (or maple syrup) together in a microwave-safe bowl in short bursts or on the stove over low heat, stirring constantly until smooth.
4. Remove from heat and stir in pure vanilla extract.
5. Add the dry oat mixture to the peanut butter-honey mixture and stir until the oats are evenly coated.
6. If the mixture looks too dry or crumbly, stir in a little more peanut butter or honey until sticky and cohesive.
7. Spread and press the granola mixture firmly and evenly onto the prepared baking sheet.
8. Bake at 325°F for 15 to 20 minutes, gently stirring once halfway through to promote even browning.

9. Remove the baking sheet from the oven and let the granola cool completely on the sheet (test doneness by letting a small scoop cool — it should harden).

10. Break the cooled granola into clusters.

Tips for Crispy, Chunky Clusters

• Make sure to fully melt the peanut butter and honey together over low heat (or in short bursts in the microwave) so the mixture is super smooth and coats the oats well.
• If your granola looks dry or crumbly before baking, don’t hesitate to add a little more peanut butter or honey for a sticky texture — this helps form those awesome clusters.
• Press the granola mixture firmly and evenly onto your baking sheet. Baking it as one solid layer will create those big, crunchy clumps everyone loves.
• Bake at 325°F and start checking at 15 minutes. Use the quick-cool test: scoop out a bit and let it cool for 1–2 minutes; if it hardens, you’re good! If not, give it a few extra minutes.
• Avoid baking at too high a temperature — a steady low heat dries the granola without burning the peanut butter or oats.
• Line the pan with parchment paper or lightly grease it for easier clean-up and to help the granola release effortlessly.
• Quick oats produce chunkier granola, while old-fashioned oats give a chewier bite; try both to find your favorite. If you’re avoiding oats altogether, a nut-and-seed blend like our Keto Granola Cereal still delivers crunchy clusters.
• Always let the granola cool completely at room temperature before breaking into pieces so it crisps perfectly.
• Keep your peanut butter granola fresh in an airtight container at room temp for 2 to 4 weeks, or freeze for up to 2 months. To get that crunch back, warm it gently in a 300°F oven for 2–5 minutes, watching carefully to avoid burning.
• Customize it by swapping in maple syrup for honey if you want vegan — see our Maple Nut Granola for a maple-sweetened, refined sugar-free version — or try almond, cashew, or sunflower seed butter instead of peanut butter for a fun twist.

Ways to Customize and Serve

Here are some of our top ways to enjoy this peanut butter granola.

1. Spoon it over your favorite yogurt. Or try it on vanilla chia pudding. Add fresh berries for a wonderfully crunchy, creamy breakfast or snack.

3. Snack on it straight from the jar. We love packing individual portions to take along hiking, park days, or anytime hunger strikes between meals.

Storage, Make-Ahead, and Freezing

It’s an easy, wholesome snack or breakfast to have ready when life gets busy — and for another fast batch option, try Air Fryer Cranberry Granola. If you’re stocking grab-and-go breakfasts, add Apple Crumble Chia Pudding to the rotation.

Common Questions and Troubleshooting

How do you make homemade granola crunchy? 

Here’s how to get your peanut butter granola nice and crunchy (and keep it that way)…
Bake at a low temp. This recipe bakes at 325°F, lower than many granola recipes I use. This low, slow bake dries it out without burning, making it perfectly crisp.
Use enough wet ingredients. Moisture from the peanut butter and honey helps form those beloved clumps that give this granola its signature crunch.
Bake it pressed firmly. Baking the granola as one pressed sheet creates those big, satisfying clusters instead of just crumbs. For another ultra-crunchy variation, try Cinnamon Raisin Granola.

How long does homemade granola last? 

Homemade peanut butter granola stays fresh and yummy for 3-4 weeks when stored in an airtight container at room temperature.

Can you refrigerate granola?

It’s best to store granola in a sealed container at room temperature to keep the crisp texture. Refrigeration can make it soft or stale faster.

How do you re-crisp homemade granola?

If your granola loses crunch, pop it in a 300°F oven for 2-5 minutes to crisp it back up. Watch closely so it doesn’t burn!
