How to Make No Bake Peanut Butter Oatmeal Bars
Making these bars is as simple as melt, mix, and chill. Here’s how:
- Line an 8×8 pan with parchment paper for easy removal.
- In a saucepan, melt peanut butter, coconut oil, and honey/maple syrup over low heat until smooth.
- Remove from heat and stir in vanilla extract.
- Add oats and optional mix-ins, stirring until fully coated.
- Transfer mixture to the prepared pan and press down firmly to form an even layer.
- Chill in the fridge for at least 1 hour or until firm.
- Slice into bars and store in the fridge or freezer.
Tips for the Best Texture and Flavor
A few simple tweaks can take your bars to the next level:
- Use natural peanut butter for fewer added sugars and oils.
- Press the mixture firmly into the pan to help bars hold together.
- Chill thoroughly before slicing to avoid crumbling.
- Add a pinch of salt to balance sweetness, especially if using unsalted peanut butter.
- For a toasty, nutty flavor, lightly toast your oats in a dry skillet before mixing (optional but delicious).
Variations and Add-In Ideas
Get creative with your flavors and textures. Try these tasty variations:
- Chocolate Peanut Butter: Mix in mini chocolate chips or drizzle melted chocolate over the top.
- Nut-Free: Use sunflower seed butter or tahini for allergy-friendly alternatives.

Recipe FAQ’s
Can I use quick oats instead of rolled oats?
Yes! Quick oats will make the bars a bit softer and easier to chew, while rolled oats give a chewier texture.
Can I freeze these bars?
Yes! They freeze well for up to 2 months. Wrap them individually or place parchment between layers.
What other nut butters can I use?
Almond butter, cashew butter, or sunflower seed butter are all great alternatives.
