If you are a lover of peanut butter, you’ve come to the right place. I’m slightly obsessed with these chocolate chip oatmeal bars. They taste like a chewy cookie but in a bar form. They’re thick, chocolate-y, and filled with creamy peanut buttery flavor and texture.

Best part about these bars? They’re naturally sweetened (thank you coconut sugar!), and gluten-free & dairy-free friendly. They’re also healthier than most granola bars and could be enjoyed as a sweet breakfast too! You’re welcome. 😉

No matter the occasion, I know you’re going to love them!

Ingredients – Everything You’ll Need

Oat flour – you can make this yourself by grinding oats in a blender/food processor or purchase it.
Peanut butter – if you use natural nut butter make sure to drain the oil. You can also swap for almond butter as well.
Coconut sugar – this is a natural unrefined sugar that responds just like brown sugar. If you don’t have access to this you can swap for brown sugar.
Egg – room temperature.
Butter – I like using vegan butter to keep it dairy free but you can also use regular butter.
Cinnamon – I love using this spice for a touch of flavor.
Vanilla – this is always a must for adding flavor in baking recipes.
Chocolate chips – you can use dark chocolate or semi-sweet.
Baking soda – I love using this baking soda for cooking.

How to Make Peanut Butter Oatmeal Bars – Step by Step

(1 + 2) First cream together peanut butter, melted butter, and coconut sugar. Then mix in egg.

(3) Then add dry ingredients to wet ingredients.

A clear bowl with coconut sugar, melted butter, and a rubber spatula.

(4) Fold in half of chocolate chips to batter.

(5) Line a square 9×9 square baking dish with parchment paper. Add batter, smooth with spatula, and sprinkle with chocolate chips.

Bake for 23 minutes at 350F then let cool before slicing into squares.

Recipe Variations

Use almond butter: to switch the flavor up and add more nutrients you can use almond butter instead of peanut butter.
Flour: I love using oat flour because of it’s health benefits, but you can also swap for regular all-purpose flour instead.
Coconut sugar: I love using natural sweeteners to keep things wholesome but you can also swap coconut for brown sugar instead.

Easy no-fuss clean up

Rather than bake the bars directly in the pan, we like lining the pan with parchment paper to easily transfer bars. This helps with minimal clean-up and no mess!

The Pan You'll Need

Every kitchen needs a 9×9-inch pan and this one is our favorite! We use this pan all the time for baking bars, brownies, and even ice cream cake. Line this pan with parchment paper for easy clean-up no matter what you make!

Keep Leftovers Fresh or Freeze

We love storing leftover oatmeal bars in either a glass container or ziplock bag in the fridge. They’re best for up to 5-7 days!

You can also freeze these bars by laying them flat in an airtight container or freezer-friendly ziplock bag for 1-3 months.

You’re going to fall in love at first bite with these chewy bars! They’re gooey, not too sweet, and just so so good. And not to mention they’re so EASY.
