These easy homemade peanut butter granola bars are made with old fashioned oats, peanut butter, chocolate chips, and peanut butter chips and make a delicious energy-filled after school snack.
These rich and chewy peanut butter granola bars are filled with a mixture of sweet chocolate chips and peanut butter chips.
Protein-packed peanut butter, an egg, and heart-healthy oats form the dough and the whole thing tastes amazing straight out of the fridge, nice and cold!
Pair a granola bar with a cold glass of milk for a quick and easy breakfast before school or an after school snack.
I love to make a batch of these before a road trip to enjoy as a snack on the go or in the hotel room for breakfast with the kids.

Ingredients
Most of the ingredients to make these homemade granola bars are probably sitting in your pantry right now!
- Old Fashioned Oats
- Peanut Butter
- Brown Sugar
- Egg
- Honey
- Baking Powder & Baking Soda
- Butter
- Vanilla
- Cinnamon
- Chocolate Chips
- Peanut Butter Chips
Variations
If you don't want to use chocolate chips or peanut butter chips, you could swap them for:
- ½ cup raisins + ½ cup chopped peanuts
- ½ cup dried cranberries + ½ cup pecans
Any dried fruit or nut that you enjoy with peanut butter would be a great option!
How to Make Them
The base of this recipe is oat flour. You simply take 1 cup of old fashioned oats and process it in your blender until it resembles powdery flour.
Whisk it together with salt, baking powder, baking soda, and cinnamon and set aside.
Then, beat together the softened butter and brown sugar with a hand mixer until it is combined.
Add the egg, honey, peanut butter, and vanilla and beat them together.
Add more oats and the chocolate chips and peanut butter chips and stir them together by hand.
Line an 8x8-inch baking pan with parchment paper and pat the granola bar dough into a packed even layer.
Bake the Granola Bars
Preheat the oven to 350°F.
Bake the prepared granola bars for 25 minutes or until the edges are light golden brown.
The pan will seem underdone but the bars will settle as they cool.
How to Slice The Bars
These bars are very soft and chewy.
To get nice, neat slices let the hot pan cool until it is safe to touch.
Freeze the bars right in the pan for 30 minutes to an hour until very firm.
Pull the parchment paper up out of the pan and place the bars on a cutting board. Use a chef's knife to slice them into neat rows.
Storage Recommendations
We LOVE eating these peanut butter granola bars cold right from the fridge so that is where I encourage you to store them.
They should keep for 5 - 7 days, but ours never last that long before being gobbled up.
You could also freeze them for up to 1 year in an airtight container.
I would recommend flash freezing the sliced bars with space between them so they don't stick together. Once frozen, you can transfer them to a plastic bag for longer storage.
Serving Suggestions
Grab a nice tall glass of milk! These bars are an amazing treat for a quick on the go breakfast or after school snack.
Add some apple slices or other fresh fruit. Anything that pairs well with peanut butter.
Looking for more on the go breakfasts? Bundle up a baggie of my classic dry granola or pour a protein smoothie. My freezer-friendly breakfast burritos are always a hit, too.

Peanut Butter Granola Bars
These yummy homemade granola bars are filled with protein and just the right amount of sweetness. Creamy peanut butter and chocolate chips make them a treat!
Ingredients
- 1 cup oat flour (1 cup old fashioned oats finely ground in a food processor or blender)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- ½ teaspoon cinnamon
- 2 tablespoon butter, room temperature
- ½ cup loosely packed brown sugar
- 1 large egg
- ¼ cup honey
- ¼ cup creamy peanut butter
- ½ teaspoon vanilla extract
- 2 cup old fashioned oats
- ½ cup chocolate chips
- ½ cup peanut butter chips
Instructions
Preheat oven to 350°F.
Line an 8x8 baking pan with parchment paper; spray paper cooking spray.
In a medium bowl, whisk together oat flour, baking powder, baking soda, salt, and cinnamon.
In mixer bowl, cream together butter and sugar on medium speed. Add egg, followed by honey, peanut butter, and vanilla.
Working by hand, stir in the oat flour mixture and the oats until just combined. Stir in chocolate chips, peanut butter chips, and peanuts.
Spoon into prepared pan, flattening with the back of spoon or hands.
Bake for about 23-25 minutes or until light brown at edges.
They may seem soft and under baked, but theyʼll set up as they cool.
Cool completely on a wire rack, then refrigerate for 3 - 4 hours before cutting. Or, let the pan cool to the touch and then place in the freezer for 30 minutes. This will help them slice very neatly into bars.
The granola bars are amazing eaten cold from the fridge, we prefer to store them there for up to 5 days.

Hi,
Sounds great! I'll be trying it for our upcoming trip.
One quick note- in the lower portion of the recipe it says to add peanuts, along with chocolate and peanut butter chips, but it doesn't list them in the ingredients. I assume it's just 1/2 a cup, like the chips, but thought I'd let you know. 🙂
Thanks!

Even though I know you didn't use real Ceylon Cinnamon, this recipe is so yummy I will forgive you for it. 🙂

Thanks, Tiffany! I'm so glad your family enjoyed them. Brent and I are headed to Indianapolis to meet friends next week, and the mom has already requested granola bars (apple cinnamon) for the hotel room 🙂
