These no bake peanut butter oatmeal bars are an endlessly customizable snack idea! They start with a simple mixture of peanut butter, sweetener, and rolled oats. Then add 1 ½ cups of your favorite mix-ins to make them your own.
Peanut Butter Oatmeal Bars
"Easy" just might be one of the most overused words on my site. In fact, I just did a search and I'm up to 112 posts and counting that mention easy in them at some point.
But I'm okay with that... As a mom of five school-aged children, I'm very big on recipes that are simple and easy. And these peanut butter honey oatmeal bars are exactly that. We're talking 5 minutes and done, simple and easy at its best!
If you've been an Unsophisticook reader for any length of time, you've probably also noticed that I love recipes that are customizable. And these peanut butter bars are no exception! Once you know the basic recipe formula, you can create dozens of variations - you really can't go wrong! At least I haven't yet...

If you're also a fan of customizable recipes, I think you'll want to add this crunchy granola bar recipe to your collection!

Easy Peanut Butter Oat Bars Ingredients
There are three main ingredients in these no bake oatmeal bars, two of which can be customized to your tastes:
- all-natural peanut butter - choose from peanut butter, almond butter, cashew butter, etc., just make sure it's the all-natural variety.
- liquid sweetener - honey, maple syrup, or agave nectar are all great choices.
- old-fashioned oatmeal - also known as rolled oats, be sure to choose this variety, NOT steel cut or instant oats.

Basic No Bake Bars Formula
My basic no bake bars formula is 1 cup of PB, ¾ cup sweetener, and 3 cups of rolled oats. To this mixture you can add up to 1 ½ cups of mix-ins of your choice. Some of my favorites:
- dried fruits: raisins, cranberries, blueberries, apricots, unsweetened coconut, cherries, mango, etc., coarsely chopped for larger pieces
- nuts: peanuts, pecans, almonds, cashews, hazelnuts, walnuts, etc., coarsely chopped
- seeds: shelled sunflower or pumpkin seeds, chia seeds, etc.
- chocolate chips: we prefer the mini chips
- ground flaxseed or hemp hearts: good source of omega-3s and protein
I typically choose 2-3 ingredients from the list above and add ½ cup of each to the mixture. For the oat and peanut butter bars pictured, I used almond butter, honey, rolled oats, dried cranberries, and unsweetened shredded coconut, and oh man, are they ever delicious!
With so many possibilities, you could make a different version of these oatmeal peanut butter bars every time you mix them up! And I'll be completely honest - sometimes they don't even make it into the pan because the mixture is so tasty right out of the pan.
What flavor combination would you like to try first? I'd love some new suggestions!

No Bake Peanut Butter Oatmeal Bars
Ingredients
- 1 cup all-natural creamy peanut butter - or almond butter or cashew butter
- ¾ cup honey - or maple syrup or agave nectar
- 3 cups old-fashioned rolled oats
- 1 ½ cups mix-ins from list below
Instructions
- In a saucepan, warm your choice of peanut butter and sweetener over low heat until they can be mixed together easily. You could also warm them in the microwave if you watch the mixture carefully to prevent it from boiling over.
- Stir in the rolled oats and your choice of mix-ins until thoroughly combined.
- Line a 9x9" baking pan with parchment paper. This makes it easy to lift the whole bar out for cutting.
- Press the oatmeal mixture evenly into the pan and allow it to cool. If desired, place the pan in the fridge for 30 minutes to speed cooling.
- Lift the entire cooled bar out of the pan and cut into 12 bars.
Recipe Notes
- dried fruits: raisins, cranberries, blueberries, apricots, unsweetened coconut, cherries, mango, etc., coarsely chopped for larger pieces
- nuts: peanuts, pecans, almonds, cashews, hazelnuts, walnuts, etc., coarsely chopped
- seeds: shelled sunflower or pumpkin seeds, chia seeds, etc.
- chocolate chips: we prefer the mini chips
- ground flaxseed or hemp hearts: good source of omega-3s and adds protein

My daughter used to make these herself when she was a teenager. She got the recipe from a friend.
Anyway on buying nuts, I swear by ordering them online. I order walnuts from Bella Viva California, and pecans from Pearson Farms in Ga. I have no affiliation with either place. I can't remember where I got my almonds, but I don't have the difficulty finding quality almonds like I do quality pecans and walnuts. I freeze them and never have any to throw out. With other brands I found too many shriveled nuts that were unfit to eat and throwing out product gets expensive.
Thank you for the recipe. It is so delicious and super easy too. :))
Vicki says
I've made these at least a dozen times, and I thought it was probably time to thank you for the recipe! We love them! I typically use just our regular peanut butter, molasses or honey, 5-minute or 1-minute oats (depending on what's in the cabinet). I don't cook the syrupy stuff and the peanut butter - if I just stir it a while, it blends together beautifully. Then I don't have worry about anything melting. (and don't tell anyone, but I've even used pancake syrup in a pinch - I know, I know ...) I've added everything from almonds, pecans, sesame seeds, chia seeds, flax seeds, cranberries or other dried berries, and whatever chips we have on hand - today it was mini choco chips, white choco chips and peanut butter chips. Oh, and I always add a tablespoon of cinnamon. They're so incredibly good!
Tara @ Unsophisticook says
Thanks for sharing, Vicki! I'll have to try the cinnamon — that sounds wonderful.

what is the nutrition value?? Calories per serving size? and Amount of protein in one serving?
Lisa says
It will somewhat depend on the add-in you use. I calculated the nutritional info using natural peanut butter, honey, oats, 1 cup of dried cranberries, and 1/4 cup of mini chocolate chips. Sparkpeople.com has a great recipe calorie calculator.

Can you use regular oats instead of old fashioned oats ?
Tara @ Unsophisticook says
When you say "regular", do you mean quick cooking oats? If so, I'd say you can use them, but it may affect the texture somewhat. Quick cook oats are just rolled thinner than old-fashioned oats so they cook faster.
Dona says
What's he best way to sore these bars?
Alexandra says
I made these today and they were delicious. Is there a way to make them firm up a little more?
Tara @ Unsophisticook says
Glad you enjoyed them, Alexandra! You could try adding a little more oatmeal, like maybe 1/2 cup, or refrigerating them will firm them up too. But I just wrap them in a little parchment paper and make sure I have some baby wipes on hand to wipe those slightly sticky fingers.
Hillary says
I would add chia seeds, almonds, and chocolate!
Tara @ Unsophisticook says
Ooh, good idea! I have a sample package of chia seeds, and I've been wondering what I should try them in.
Amy says
How do you keep the chocolate chips from melting after you warm the honey and PB? I've made something like this before and the chips just ended up melting and if I let it cool too much I couldn't mix in the chips?
Tara @ Unsophisticook says
Yeah, it's a little hard to find that sweet spot where the mixture has cooled just enough to stir them in without melting. A lot of times we'll just press them into the top after it's cooled a bit — works just as well!
