Oat Flour Brownies

When it comes to oat flour recipes, I love chocolate protein bars, cookies and cream protein bars, and these oatmeal brownies.

It’s no secret that I love brownies. Whether it be flourless brownies, keto brownies, or vegan brownies, I play no favorites- they are all delicious. However, I usually reserve these for desserts or a cheeky post-lunch treat.

I’ve been trying to find an excuse to have brownies for breakfast. As someone who tends to stick to oatmeal or pancakes, it had to be quite a special brownie. Luckily, I’d been meaning to try an oat brownie for quite some time, and have found the answer with this recipe!

These oatmeal brownies are your excuse to have brownies for breakfast. They taste like brownies, look like brownies, and if you didn’t know the ingredients, would think they were legit brownies.

They are thick, fudgy, and filling- Everything you want in a good brownie and a good breakfast recipe. The combination of oats (healthy carbs), maple syrup (natural sweetness), and peanut butter (healthy fats) make it the perfect excuse to have chocolate for breakfast. 

Now, I have to be real here. If you are after Betty Crocker Boxed mix brownies (like these ones), you’ll be disappointed. These are, after all, healthier brownies. However, if you follow the instructions and don’t sub out any of the ingredients (AND add the optional chocolate chips), you’ll feel satisfied and be able to have a real brownie for dessert!

How do you make oatmeal brownies?

The Ingredients

  • Oat Flour– Either homemade oat flour or store-bought. Be sure that the consistency is extremely fine, otherwise, you risk the brownies drying out. 
  • Cocoa powder– Use a good quality cocoa powder, as that makes a huge difference as to how intense the chocolate flavor is. I used dark cocoa powder, as I love the rich flavor and black color. 
  • Granulated sweetener of choice– Any granulated sweetener can be used. Coconut sugar, brown sugar, or even sugar free substitutes, like monk fruit sweetener and erythritol. 
  • Peanut Butter– works as a fabulous replacement for butter, and helps give these brownies an extra gooey texture. You must use smooth and drippy peanut butter, otherwise, the batter will be too thick. 
  • Maple syrup– Adds extra sweetness, AND helps them be even more fudgy. 
  • Coconut oil– Replaces the need for butter, and gives the brownies that gorgeous sheen, Yes, even for breakfast! 
  • Eggs OR flax eggs– Either room temperature eggs or if you want these brownies to be vegan, use flax eggs. 
  • Chocolate Chips– Optional, but highly recommended to give an extra boost of chocolate. 

The Instructions 

In a small bowl, add your oat flour and cocoa powder and mix together, until combined. In a large mixing bowl, combine your coconut oil, maple syrup, peanut butter, and granulated sweetener of choice, and whisk together, until glossy and smooth. Add your eggs (or flax eggs) and whisk until combined. Slowly add in your dry ingredients, folding it into the batter slowly. If using chocolate chips, fold them through at the end.

Transfer the brownie batter into a lined pan and bake for around 30 minutes. Remove from the oven and allow to cool in the pan completely.

Can I make these brownies lower in fat?

If you’d like lower fat brownies, make these substitutions.

Replace the coconut oil with unsweetened applesauce. The brownies will be more cake-like, and you’ll need to cut the cook time to 25 minutes-30 minutes. Also, be sure to use a zero calorie sweetener. 

Tips to make the best breakfast brownies

  • If you use homemade oat flour, you MUST blend it to a very, very fine consistency. If the oats aren’t ground to a fine powder, your oat flour will replicate quick oats. This will result in dry and crumbly brownies. 
  • Avoid overbaking the brownies, as the brownies continue to cook in the pan.
  • If you’d like a higher protein brownie, you may enjoy protein brownies
  • Feel free to add chopped nuts into the batter, or even add some healthy frosting.

Storing and Freezing Brownies

  • To store: Breakfast brownies should always be stored in the refrigerator, in a sealed container, for up to 2 weeks. 
  • To freeze: Place brownies in a ziplock bag and store in the freezer for up to 6 months.

    1. YES! 🙂 Please let me know how it turns out! It depends on what size pan you use! I had around 9 decent pieces!

      1. I got the following nutrition info when using bananas, peanut butter and plant fusion chocolate protein powder…

        155 calories
        8.3 fat
        15 carb
        2.7 fiber
        8.8 protein
        7.6 sugar

  1. Brownies for breakast? YES PLEASE. Also, your brownies ALWAYS have that perfect crackle topping!! How do you do it!?

      1. I found that the bananas stopped the brownies from cooking… They’re still pretty tasty but way too gooey! next time Im going to try just 1 banana

        1. Thanks for letting me know, Jade- I’d still recommend using the full amount of bananas and allowing them to cool completely before refrigerating- they firm up beautifully.

  2. My staple breakfast is definitely PB&J. However I need to break that because it’s not only my staple breakfast, it’s my staple dinner as well haha. I have has salsa and eggs before and I agree, it’s pretty fabulous. Hack! Make an omelet with salsa and cheese inside it. It’s like a present of delicious ?

  3. I cannot eat eggs without salsa or avocado, just cannot! It’s too good of a combo. And why have I never tried brownies for breakfast? Thats genius!

  4. Eggs – haha, of course. I’d add some Salsa too, great idea! Though these Brownies look delicious and I might trade them …..especially cause of the Banana Chunks. Happy New Year Love!

  5. I saw the Instagram post you did of these and seriously said out loud “HOW”. Arman! What the heck. These look so good + they’re healthy + 4 ingredients? I’m confused in the best possible way. You’re a magician.

  6. Eggs and salsa are amazing together. Throw in some black beans, avocado, cheddar cheese and I’m there.

      1. I added 1 1/2 T of coconut sugar, it went sweet but not super sweet, but it turns out really good, everybody loved it.

  7. Eggs and salsa are delicious! But, you HAVE to try eggs with marinara. WHUUUUUUT I know it sounds weird, but try it with basil and Mozzarella! Delicious!
    And god, you just HAD to post these brownies. Time to make another recipe where I’ll eat the whole batch of something LOL!

  8. I’ve come close to eating brownies for breakfast… Meaning I ate a brownie after I had eggs. Maybe I should just skip the first course?

  9. I don’t know why but that remark about dancing the tango minus the dancing has me cracking up! Perfect recipe to bring in the New Year 🙂

  10. Dang all I have is whey!!! 🙁
    My breakfast is always eggs in some shape or form. The salsa egg combo is amazing and avocado is the icing on the cake! Must have that again soon! And add cheese… Because cheese.
