Easiest Microwave Chewy Peanut Butter Granola Bars


So I had surgery on my hip bright and early this morning, so early I’d probably consider it to be the middle of the night (waking up at 4:00am is like my worst nightmare. Actually I wish it would have been a nightmare, because that would mean I would have still been asleep and dreaming at 4 :)) but anyway things went so well I’m right back to work today. Okay just kidding, I’m basically going to be a couch potato for the next week. Meaning I’m going to be spending unbelievably ridiculous amounts of time on Pinterest dreaming of all the delicious things I could be making, browsing the web for beautiful kitchen ideas that I’m most likely never going to use, shopping for clothes online and pretending to care about fashion and begging my husband to learn to cook (as he refuses) so he will make something other than a box of mac and cheese with a side of crackers and string cheese for dinner or picking up take out every night. Why do I care if he learns to cook? Well I’m going to need some dinner this week and I just want him to see how fun cooking can be (which he would adamantly disagree with)… I know him too well though so I made freezer meals. I also made some of these amazing and incredibly easy granola bars yesterday. So easy that I’m sure I could make more of these during this lounge week. The coating is made in the microwave and they require no baking so these could easily be prepared in 10 minutes. These tasty, mostly healthy yet seemingly dessert like bars remind me a lot of these treats and these (minus the topping). I have a feeling you are going to love these not only for there simplicity but of also for their addictive, peanut buttery deliciousness. Enjoy!

Microwave Peanut Butter Granola Bars

Yield: 12 Servings

Prep Time: 10 minutes
Cook Time: 2 minutes


  • 2 cups quick oats
  • 1 1/2 - 2 cups Rice Krispies cereal*
  • 1 cup chunky peanut butter (or 3/4 cup creamy peanut butter)**
  • 1/2 cup honey
  • 1/4 cup dark brown sugar
  • 1/8 tsp salt
  • 1/2 tsp vanilla extract


  1. Line an 8 by 8-inch baking dish with aluminum foil leaving a 2-inch overhang. In a large mixing bowl, toss together oats and Rice Krispies, set aside. In a separate microwave safe mixing bowl, combine peanut butter, honey, brown sugar and salt. Heat mixture on HIGH power for 1 minute, remove and stir. Return to microwave and heat on HIGH power 1 minute longer. Remove from microwave, pour in vanilla and whisk mixture for 30 seconds. Pour peanut butter mixture over oat mixture and toss well to evenly coat. Pour mixture into prepared baking dish, firmly press mixture into an even layer. Cover with plastic wrap and freeze 10 - 15 minutes or chill in refrigerator 30 minutes. Lift bars from dish using foil overhang and cut into squares. Store in an airtight container.
  2. *I used 2 cups Rice Krispies but I thought it was slightly too much so I'd recommend start with 1 1/2 and if you think it could use more add in another 1/2 cup.
  3. **If you use extra crunchy you will probably have to add a few more Tbsp as it will increase the peanut to peanut butter ratio.
  4. Recipe Source: adapted slightly from Kraft


  • Averie @ Averie Cooks: I had no idea you were having surgery! I hope you’re doing okay (and frankly cannot believe you’re blogging!!!) but I wish you speedy healing!

    I love Special K Bars and have a recipe for them as well as about 10 versions of no-bake PB-based granola bars. I love adding Rice Krispies cereal to them as you did. That little bit of extra crunch goes a long way! Yours turned out perfectly! April 24, 2013 at 5:24pm Reply

  • Shawna: I just tried these this morning, and I added chocolate chips on half the pan and white chocolate chips on the other half… the entire family LOVED them! They’re so easy to make, take very little time to set up, and you can add different toppings or dried fruit into the mix… thanks to your recipe, I’ll never buy store-bought granola bars ever again. I also love that the clean-up is quick and easy with the foil in the pan and very few dishes used. Right now I just have what is left in a Ziploc bag, but I think when I make more, I’ll be wrapping them individually in saran wrap and storing them on the breakfast shelf right next to my homemade packets of brown sugar and cinnamon oatmeal and the shelf stable fruits so my family has a healthy, homemade variety of quick breakfast foods to choose from, rather than constantly buying the expensive sugar and preservative-filled cereals! Love, love, love this recipe! Thanks so much for sharing!!! May 4, 2013 at 9:09am Reply

    • Jaclyn: That is great to hear Shawna!! I’m so glad you enjoy this recipe, and you’re very welcome :)! May 7, 2013 at 9:00am Reply

  • Kathy Genschorck: Gonna try these soon. They sound yummy and healthy. Might add craisins. August 4, 2013 at 7:12am Reply

  • Courtney: These are so good! I made some for her snack after her first day of school and she ate it up so fast! She’s so excited tk make them herself! Do you know about how long they would last wrapped in Saran Wrap in a ziplock? August 15, 2013 at 5:56pm Reply

    • Jaclyn: They’d probably last 1 week at room temp in an airtight container or ziploc. That is so cool your daughter wants to make them herself! I’m so glad she liked them! August 20, 2013 at 4:09pm Reply

  • colleen: can you tell me where you purchased the kraft colored parchment wrap? It relaly finishes them off & would look great for Christmas baking these bars :) Thanks August 15, 2013 at 9:01pm Reply

    • Jaclyn: I just bought it at a local kitchen goods store but you can find it online, it’s just a natural unbleached parchment. Hope that helps! August 19, 2013 at 4:19pm Reply

  • Kira: These are awesome. They are delicious and simple. My family loved them. Next time I may try adding a little coconut or white chocolate chips or even some fresh chopped peanuts. I know, I could use crunchy peanut butter, but for some reason I am not a fan. The peanut butter taste different to me :). Crazy I know! Thanks for sharing. August 16, 2013 at 5:16am Reply

    • Jaclyn: I’m so happy to hear you liked these Kira! Those additions do sound delicious! August 26, 2013 at 8:47pm Reply

  • Amber Rist: Is there something I could substitute for the honey? I never seem to have any in my kitchen and never seem to remember to buy any at the store! thanks. August 16, 2013 at 11:52pm Reply

  • Alexandra D.: This was very good! I think I might try creamy next time though because I thought the chunky put too much of a peanut taste to it. Thanks for the recipe. Hope my kids like it since they’ve been so use to the conventional. August 21, 2013 at 4:47pm Reply

    • Jaclyn: I’m glad you like these Alexandra! And yes everyones preferences are different – I’m obsessed with chunky peanut butter but probably less than half of peanut butter eaters prefer chunky :). Thanks for your comment! August 26, 2013 at 8:53pm Reply

  • Laura: These have got SOOOO much honey in them could I leave some of it out or replace some????
    Oh and can I leave out the vanilla too (I’ve run outta that!!) August 22, 2013 at 4:44am Reply

  • Alexandra D.: I wanted to add in some Nutella. Do you recommend I was thinking about using 3/4 peanut butter and 1/4 Nutella? August 22, 2013 at 10:44pm Reply

    • Jaclyn: If you use creamy peanut butter than I’d do 1/2 cup and 1/4 cup nutella if you do crunchy peanut butter then yes I’d probably use 3/4 cup and 1/4 cup. I hope you love them! The nutella addition sound delish! August 26, 2013 at 8:44pm Reply

    • Jaclyn: I think that should be fine and delicious – I love almond butter! September 12, 2013 at 3:02pm Reply

  • Kylee: I just made these granola bars and my family LOVED them! My dad can’t eat nuts right now (but can have peanut butter), so instead of the chunky peanut butter I used creamy and added mini chocolate chips as a filler! They turned out awesome! I am going to try adding flax seed to my next batch! September 12, 2013 at 10:50am Reply

    • Jaclyn: The chocolate chip addition sounds delicious! I’m so glad you family liked them Kylee! The flax seed sounds like a great idea too! September 12, 2013 at 2:55pm Reply

  • Kristy Zink: I made these today. Super easy! My kids loved them. My son said they were “Epic”. I should have made a double batch. These are going to go fast. September 17, 2013 at 1:13pm Reply

  • Kellie Thompson: These taste delicious and my kids love them (finally a bar they like) BUT, they did not hold together…they are granola! Any suggestions? September 20, 2013 at 5:18pm Reply

    • Jaclyn: If yours came out like a dry fall apart granola I would recommend that you reduce the amount of dry ingredients slightly and maybe even reduce the amount that you microwave the coating, if it was more like a wet fall apart granola I would microwave the coating mixture a bit longer and press the bars more firmly into the dish. Hopefully that will help! September 29, 2013 at 12:54pm Reply

  • leah: … just a quick question (batter is already all mixed in a bowl), the quick oats don’t need to be cooked, correct?
    i like the idea of chocolate chips. i think i am going to add a little. BTW, i didn’t have chunky PB so i used creamy and added some chopped peanuts (omitted the salt cuz they are salty) October 4, 2013 at 1:12am Reply

    • Jaclyn: No the quick oats don’t need to be cooked. I hope you love these! October 4, 2013 at 6:24am Reply

  • mandy: Cant wait to try these next week. Yumo November 14, 2013 at 5:30pm Reply

  • Jazzy: May I ask if I could use the regular rolled oats instead of the quick oats? Thank you! November 28, 2013 at 3:18am Reply

    • Jaclyn: I wouldn’t recommend it simply because of the texture it would give, although if you buzz them through a food processor for a bit it might work. November 28, 2013 at 8:04pm Reply

      • Jazzy: What a great idea! I’m so happy that I found your great recipe. Thank you! November 28, 2013 at 8:34pm Reply

  • Stephanie: Omg! These look so good! I can’t wait to try them! The only thing is… sadly, I don’t have a microwave, which is ironic since I’m a college student, but would I be able to make this on the stove?

    Thanks! :D January 19, 2014 at 10:38pm Reply

    • Jaclyn: That should be totally fine :). I would cook it a little longer though because it takes longer to heat on the stove top then the microwave. January 20, 2014 at 3:26pm Reply
