These peanut butter oatmeal chocolate chip bars are just right for dessert or even breakfast! This is a vegan and gluten free treat that you’re sure to love.

Before we had a peanut allergy in the house, peanut butter and chocolate was one of my favorite dessert combinations.
There’s something about it that’s just right! Chocolate and peanut butter go so well together. Thankfully, we can still make a lot of those favorite recipes allergy friendly simply by substituting sunbutter.
If you can have peanuts, try this recipe as is! If not, use sunbutter or another seed butter instead – these bars will still be good!

Ingredient Notes
- Certified Gluten Free Oats – If you are gluten free, you need to make sure that the oats that you use are certified gluten free. Two brands that we like are One Degree Organics Oats and GF Harvest Oats. These are both made in an allergy friendly facility.
- Ground Flax Seed Meal – You will need this to make a flax seed egg replacer. You can use any brand that works for you.
- Gluten Free Flour Blend – Namaste Perfect Flour Blend works well in this recipe. You could use a different brand if you prefer. I don’t recommend coconut flour or almond meal in this recipe.
- Dairy Free Chocolate Chips – Both Enjoy Life and PASCHA Chocolate make delicious allergy friendly chocolate chips.
Substitutions
- If you’re not gluten free, feel free to use regular flour rather than gluten free flour.
- If you can’t have peanut butter, use sunbutter, or any seed or tree nut butter that is safe for you.
- If you would rather use a regular egg, you can do that in place of the flax egg.
Top Tip
These bars need to be completely cool before you cut them into squares. If you try to cut into them when warm, they will be crumbly.

Peanut Butter Oatmeal Chocolate Chip Bars (Gluten Free, Vegan).
Ingredients
- 1 cup creamy peanut butter or sunbutter

- ½ teaspoon baking soda

Instructions
- Preheat oven to 350 degrees F. Line a 9 inch square pan with parchment paper so that there is an overhang on both sides.
- In a large bowl, mix together the ground flax seed and the water. Let sit for a few minutes until it forms a gel.

- Spread the mixture into the prepared pan.
- Bake at 350 degrees F for 25-29 minutes, or until a toothpick inserted in the center comes out clean.

These bars looks very moist. I have to buy some golden ground flax seed to be able to make this recipe! Have to make this ASAP ;-)
Kelly
Thanks, Olivia! Regular ground flax seed will work, too, you might just see little flecks.

you have come to my rescue just in time, I am having some friends round on Saturday night for a Eurovision party – people in England will know just how sad this is – but I wanted something sweet for people to munch on and I think this will do the trick. Love it!
Kelly
I hope you love them! Have a great weekend!
Sarah @Whole and Heavenly Oven
Definitely looking forward to relaxing with the fam this holiday weekend! I’m pretty sure these bars would make the weekend complete. They seriously look SO tempting, Kelly!
Kelly
Thanks, Sarah! Have a great weekend!

Kelly, can I substitute the flax see for flax meal? If so, do I need to change the amount of water? They look great!
Kelly
Hi Susan, If you mean ground flax seed, then yes, that is the same as flax seed meal. You can’t use whole flax seeds, because they won’t become a gel. Hope that helps!

Natalie @ Feasting on Fruit
I’m loving these bars! They look like the sort of dessert that you could bring to any party and they would disappear at lightning speed! Most of my favorite things have vanilla, dates, and oats, but your winning combo is definitely high on my list too! It’s funny how the not-so-fancy combos are the ones that we keep coming back to :)
Kelly
Thanks, Natalie! I love the sound of vanilla, oats, and dates! Yum!
