Today is day 3 of Granola Week, and if you missed my recipes for Tropical Granola and crunchy Cherry Almond Quinoa Granola you should go check them out!  I’ll wait for you right here. :)


You’re gonna love today’s granola. It can pass for breakfast, a snack, or even dessert. When it comes to food, simplicity is often best and that is so true with this recipe. You only need 4 ingredients and 10 minutes of prep time to make amazing, crunchy peanut butter granola.


Do you get as excited as I do about recipes like this one? So excited that you just can’t help but make them immediately? I thought so. I bet I know what you’ll be making later today. It’s a good thing you probably already have all 4 ingredients in your pantry!

This granola is perfectly balanced in its peanut butter flavor. Not too much peanut butter that it’s overwhelming, but enough that it is unmistakeably peanut butter granola. Julia won’t touch this of course, since she’s never liked peanut butter. William, however, loves peanut butter and this is his favorite of all of the granola recipes I make. He loves eating a bowl of it with some milk for breakfast.

While this granola bakes, it will fill your house with the most delicious peanut butter aroma. It will be hard to resist eating spoonful after spoonful as soon as the pan comes out of the oven, but do try! The flavor is great right away, but if you wait, the granola will crisp up as it cools. It’s so much better when crisp.


This crispy, crunchy peanut butter granola is delicious by the handful, but I usually enjoy it with a splash of milk. And if I’m feeling indulgent, I do this:

4-Ingredient Peanut Butter Granola
Recipe type: Breakfast
Serves: Makes 5 cups
This Peanut Butter Granola is made with just 4 ingredients, in only 10 minutes of prep time. It's crisp and lightly sweetened, with just the right amount of peanut butter flavor.
  • 5 cups (430g) old-fashioned oats
  • ½ cup peanut butter*
  • ½ cup honey
  • 1 tsp. vanilla extract
  1. Preheat oven to 275 degrees F.
  2. Place oats in a large bowl. Combine peanut butter and honey in a liquid measuring cup. Heat in the microwave for about 45 seconds, until the peanut butter starts to melt. Whisk peanut butter and honey to blend. Add in vanilla and whisk to incorporate.
  3. Pour the peanut butter mixture over the oats and stir until well combined. Spread granola in an even layer on a rimmed baking sheet. Bake for 20 minutes, stir, and then bake 10-15 minutes more until granola becomes light golden brown. Let cool completely on baking sheet. The granola will become crisp as it cools. Store granola in an airtight container for up to two weeks.
*Note: I only buy natural peanut butter, so that's what I used here. Both natural and regular will work fine.

  1. 4 ingredients!? Sold. Gotta make this one!

  2. I need this in my life!! Granola is the best thing ever – but it’s so expensive. I really need to start making it more!

    • Yes, the good ones in the stores are so expensive! I haven’t figured out how much a batch of homemade costs to do a price comparison, but I’m sure homemade is cheaper, even if you do use some pricey ingredients like real maple syrup. You really should make your own granola often! It’s the best!

  3. {Squeeee!} I was wondering how you were going to top your other two granola recipes, but you totally did!!! I love that there are only 4 ingredients unless you count the chocolate chips and bananas, which I do, because those seem essential! Pinned!

    • Now the pressure is on for tomorrow and Friday! I love the two recipes I have yet to post, and I hope you will too! I like to eat this granola for a late-night snack, and the chocolate chips and bananas are pretty much required then. :)

  4. Yum! I love peanut butter granola bars, and this sounds like a good way to eat peanut butter granola, too!

    • If you like peanut butter granola bars, then I think you would love this granola. I’d love to find a good recipe for peanut butter granola bars!

  5. I’m loving your granola recipes, and this one is no exception! Peanut butter granola is the best, hands down!

  6. Peanut butter granola? This looks amazing!

  7. Mmmmmmmm peanut butter! I kind of want to make this granola, take a spoonful of peanut butter, and just shove it in a bowl of the granola and eat it right off the spoon!! Is that allowed?

  8. I never had success making granola but you make it look so easy! Wishing I could grab a handful of this!

  9. Your photos are AMAZING! Seriously so pretty and I love that this granola is only 4 ingredients! Pinned and sharing as my feature for SNF this weekend!

    • Thank you so much, Chelsea! Yay!!! I really appreciate you featuring my granola! It’s amazing how only 4 ingredients can create such a yummy breakfast/snack!

  10. Do you think this would be just as good without the honey? Thank you!

    • The honey adds a little sweetness and helps the granola cluster together. I haven’t tried making this without honey, but it might work because there is the peanut butter to help bind it. If you try it, let me know how it goes!

  11. Michele Trombley says:

    Do you know how many calories and how many servings this is?

    • I don’t calculate the nutrition facts for my recipes, but there are many online tools that can help. The recipe makes about 10 1/2-cup servings.

  12. Vickie Saldana says:

    This recipe sounds perfect for me, most of he store bought granola that the like here has nuts, I can’t have nuts or seeds because of my Ileostomy and I have been looking for an easy no nut/seed recipe. THANK YOU!

  13. I”m in the process of baking this granola right now!!! I have never made granola before so I”m excited!!! My husband and I and two kiddos will eat peanut butter like crazy so I have a feeling this will become a favorite to all them and myself!! I can”t wait to try it!! :) P.S. my house smells amazing!!!!

  14. Vickie Saldana says:

    I just made this 4 ingredient peanut butter granola this morning and it came out delicious, I threw 3/4 cup of chocochips in it also.
    I couldn’t stop eating it OMG! Thanks for the recipe, finally granola I know I CAN eat because there are no nuts, it tastes like there is because of the little crunchy clusters, but there isn’t. =)

  15. Sharon Salerno says:

    is this gluten free? Love the fact that there is only 4 ingredients.

  16. Jule Rosen says:

    I would love to try this recipe because I love peanut butter and granola, but I hate honey! Do you think agave would work in place of honey?

    • Agave should work, although I have found it to be sweeter than honey so you might end up with a sweeter granola. Another option would be to use pure maple syrup, which I do use in a lot of my homemade granolas. Let me know how it turns out!

  17. Hailey Moore says:

    Is your 4 ingredient peanut butter granola gluten and sugar free?

  18. Hi! I’d just like to thank you (well, sort of….) for this amazing recipe. Here’s the good news: my husband thinks it’s the best granola in the world. I, as it turns out agree. The bad news? I have to now make it in DOUBLE batches EVERY week or so. Seriously. It’s so good…and super EASY to make. Thank you so much.

  19. Meredith Ulino says:

    I am disappointed with how this turned out. Made it last night when I was craving something sweet. It was easy enough to make with only 4 ingredients, but mine never crisped up like it says it will. Even today it still seems rather pasty. :(

  20. Would maple syrup work instead of the honey?

    • I haven’t tested this recipe with maple syrup, but I’ve made many granola recipes with maple syrup so I think it would work well. I hope you enjoy this granola!
