Peanut butter granola is super easy to make at home. You can add in all of your favorite mix-ins, or just keep that peanut butter flavor strong.

I’ve been making my own granolas for years now.

It used to seem like such an odd thing, but then I realized that I nearly always have the ingredients on hand to make a great granola, from the oats to nuts to dried fruits.

I don’t like standard oatmeal much, but I love baked oatmeal and granolas. Toasting oats adds a surprising amount of flavor, and of course when you’re adding your favorite ingredients you can’t go wrong.

This peanut butter granola is a super simple version of the varieties I make. All you need are oats, peanut butter, honey, and peanuts — items you probably already have in the pantry!

What can I add to peanut butter granola?

There is so much you can do with homemade granola to make it match your cravings.

I like to add dried cranberries to give it a bit of PB&J taste. You can use freeze dried fruit if you like, but I think the regular dried fruits add better flavor and texture.

If you want to go sweet, add mini chocolate chips and hot chocolate marshmallows. Love chunky monkey flavor? Add banana chips along with the chocolate!

The important thing to remember is to add these mix-ins after baking the granola, otherwise they can melt or burn in the oven.

Sprinkle them on top and press down gently to help it adhere and make those lovely granola chunks.

How do you get granola to stick together?

Resist the urge to stir too much. The sugars in the honey will caramelize as the granola bakes, helping to form the clusters. Stir just once, halfway through, to make sure the oats are toasting evenly.

When you remove the granola from the oven, use a spatula to press down gently on the granola to stick it together.

Don’t touch it again until it is completely cooled! Then, you can break apart the clusters with a spatula as you put it into a container for storage.

How long does homemade granola last?

Stored in an airtight container, granola will last for up to 1 month.

Keep the container in your pantry, not in the fridge! Storing it in the refrigerator will make it soggy instead of crispy.

I keep mine in a glass Weck or Mason jar, but any container with a lid or even a zip-top plastic bag will work.

Can you freeze granola?

While storing in the refrigerator doesn’t work that well, you can freeze granola!

Place the cooled granola into a plastic bag and remove as much air as possible.

This is easy if you have a vacuum sealer, but you can also do it yourself by putting a straw into the opening and sealing the bag. Suck out as much air as possible, then quickly remove the straw and close the bag.

Thaw on the counter overnight before eating. Frozen granola will last for up to 3 months.

Looking for other granola options? Try mocha java granola, lemon blueberry granola, or apricot granola.
