Ingredient Notes
Homemade Oat Flour: Instead of regular flour, this recipe uses homemade oat flour. It is easy to make in a blender or a food processor and makes these gluten-free blondies bake up super soft and chewy. If you prefer baking with regular flour, make my Vegan Blondies recipe!
Peanut Butter: Use natural creamy peanut butter for this recipe. The kind you need to stir. My favorite is Teddie's Peanut Butter.
Non-Dairy Milk: I used oat milk, but soy milk, almond milk, or even coconut milk will work.
Chocolate Chips: Use whatever dairy-free chocolate chips you like in these gluten-free blondies. I like Enjoy Life or Trader Joe's.
Variations and Substitutions
Use any nut butter you like in this recipe! You could use almond butter, cashew butter, or make this recipe nut-free with sunflower seed butter!
Also, feel free to use any chocolate chips you like. Milk chocolate or white chocolate would also be great. Just make sure they don't contain milk to keep these blondies dairy-free.
Special Equipment
You will need a blender or a food processor to make homemade oat flour. I used a Vitamix blender.
How to Make Gluten-Free Peanut Butter Blondies
Step 1. Add rolled oats into a blender or food processor and blend on high until they reach a flour-like consistency.
Set aside.
Step 2. Then, in a large mixing bowl, add peanut butter and brown sugar. Mix with a spatula until combined.
Next, add the non-dairy milk and vanilla and mix until well combined and creamy.
Step 3. Then, add homemade oat flour, baking powder, and salt, and mix to incorporate. The mixture will be thick!
Next, add the chocolate chips and stir to distribute.
Step 4. Finally, scrape the batter into a prepared 8x8-inch square pan, top with more chocolate chips, and bake in a 350°F oven for 28-30 minutes.
Allow the blondies to cool completely before slicing and serving.
Recipe FAQs
Place the blondies into an airtight container and leave at room temperature for up to 4 days. Or freeze for up to a month!
No! Store-bought oat flour absorbs more liquid, so if you substitute it here, the blondies may become dry or crumbly.
Oat flour is great for making blondies because it adds so much chew and flavor without needing multiple flours or stabilizers like xanthan gum!
Expert Tips and Tricks
To prepare the baking pan, grease it with shortening or pan spray and insert a parchment sling for easy removal and slicing of the Gluten-Free Peanut Butter Blondies.
The blondie batter is really thick, so scrape it into the prepared pan and use the back of a rubber spatula to press it out evenly into all the sides and corners of the pan.
Allow the blondies to cool completely before slicing. They need to be cool to have structure.

How have I never thought of this combination?!! These look truly delicious, thank you so much for sharing your recipe.

They are so chewy and delicious! Thanks so much 🙂

I added 1 tbsp of cocoa powder to it and it was delicious. Very peanut buttery so the cocoa cut the flavour slightly.

Oh wow- wow-Wowza! I just made these and couldn’t even wait for them to cool. They are perfect!! I was reluctant to double the recipe (as sometimes it doesn’t work out)- but this worked perfect! I made it in a 9x13 pan and cooked in my convection oven at 350* for exactly 26 minutes and they were perfect! I doubt this tray will last longer than an hour! My family of 7 all agreed it’s a keeper! Thanks for a great recipe!
