Ingredients You Need for This Recipe
Here are the ingredients you need to make this recipe. Reference the recipe card at the bottom for exact measurements and the notes below for substitution ideas.
- Mini chocolate chips: I recommend using Enjoy Life dark chocolate mini chips.
- Sugar: I like to use raw cane sugar when making brownies. Some brownie recipes call for maple syrup but I love a good crackly top brownie and it's the sugar and boiling water that creates it!
- Cocoa Powder: Dutch processed cocoa powder makes the best brownies but use any cocoa powder that is available to you.
- Butter: I'm definitely on the no coconut oil train for this one. I've found coconut oil tends to make these rather oily, but if that is all you have on hand definitely use it.

Recipe FAQs
Yes, however you will want to grind up the oatmeal into flour to ensure classic brownie texture.
Omit cocoa powder and bake as the recipe calls for.
You can easily make it using a food processor. Grind oatmeal until it's a very fine powder. If making it homemade isn't your thing some of the best oat flour brands are available on Amazon or at your local grocer. My personal favorite brand is Anthony's Organic Gluten Free.
I've tried a variety of different flours in baking brownies and I like all purpose flour and oatmeal flour the best. Almond flour is also great to use but gives the brownies a slightly grainer texture. I've also made avocado flourless brownies and sweet potato flourless brownies that taste great too! It's all about personal preference.
If you've wondered if you can substitute all purpose flour for oatmeal flour in this recipe, I would not recommend it. Oat flour does not have gluten and also sucks up moisture much more than all purpose flour.
