I prefer homemade granola because many store-bought varieties are loaded with refined sugars, hydrogenated oils, and preservatives. This peanut butter version keeps things simple: it delivers rich flavor and satisfying texture while letting you control the ingredients. Use natural peanut butter (peanuts and salt only) and a good-quality sweetener for the best results. The recipe is forgiving and easy to customize with your favorite mix-ins.

Recipe ingredients

Making granola at home lets you choose quality ingredients and avoid additives. This recipe uses just a few pantry staples and can be adapted as needed.

Peanut butter granola recipe ingredients
  • Oats: Old fashioned rolled oats give a chewy texture and large clusters. Quick oats can be substituted in a pinch, but texture will differ.
  • Peanut butter: Use natural peanut butter with only peanuts and salt. Avoid varieties with added sugar for balanced sweetness.
  • Maple syrup: Pure maple syrup adds sweetness and helps clusters bind. Honey or another liquid sweetener may be used instead.
  • Oil: A small amount of coconut oil works well, but any neutral unrefined oil (or a light olive or avocado oil) will do.
  • Salt and cinnamon: A pinch of salt brings out the flavors; cinnamon is optional for warm depth.

How to make this recipe

The key to large, crunchy clusters is packing the oat mixture into a thin, compact layer and not stirring it while baking. Allow the granola to cool fully on the pan before breaking it into chunks to preserve the clusters.

Pro tip: Choose all-natural peanut butter (peanuts and salt only) to avoid added hydrogenated oils, excess sugar, and unnecessary preservatives.

How to make peanut butter granola
  1. Preheat the oven to 325°F (165°C). Line a large rimmed baking sheet with parchment paper.
  2. In a microwave-safe bowl or on the stovetop, gently warm the peanut butter and coconut oil until melted and smooth. Stir in the maple syrup, cinnamon (if using), and salt.
  3. Add the rolled oats and mix until every oat is coated with the peanut butter mixture.
  4. Pour the mixture onto the prepared pan and spread it into an even layer about 1/4″ thick. Press it down firmly to compact the oats — this helps create clusters.
  5. Bake on the middle rack for about 25 minutes, or until golden. Do not stir during baking.
  6. Remove from the oven and allow to cool completely on the pan without disturbing it. Once cooled, break into large clusters and store in an airtight container.

Recipe FAQs

Is peanut butter granola healthy?

Compared with many commercial granolas, this version is lower in refined sugar and uses minimal oil. Using natural peanut butter and pure maple syrup keeps ingredients simple. While granola is calorie-dense, this recipe emphasizes whole-food ingredients and lower added fat compared with some store-bought blends.

How do you make granola clusters stick together?

Make clusters by packing the mixture tightly on the baking sheet and avoiding stirring while it bakes. Cooling completely on the pan lets the sweetener and peanut butter set, so the granola can be broken into large chunks.

Recipe notes

  • Peanut butter choice: For best flavor and cleaner ingredients, use natural peanut butter with only peanuts and salt.
  • Add-ins: After baking, stir in chocolate chips, dried fruit, coconut flakes, or roasted peanuts if desired.
  • Storage: Keep granola in an airtight container at room temperature for up to two weeks.
