Why You’ll Love Vegan Brownie Baked Oatmeal

  • No Mushy Texture – One of the biggest complaints about oatmeal is that the texture is mushy; however, with baked oatmeal, that’s not a concern. Baking allows for it to crisp up on the tops and edges and perfect cook the oatmeal itself. If you love oatmeal cookies, you’ll love baked oatmeal as well.
  • Lots of Flavor – Most of the time, we hear that people aren’t fans of oatmeal because they lack flavor and they aren’t sure how to fix that. This vegan banana bread baked oatmeal has all the flavor you could want inside of it! Thanks to the banana, nuts, and optional chocolate chips, you have a really great balance of flavor that you’ll love.
  • No banana – so many people asked us to make a banana-free baked oatmeal and here you go!

Instructions

  • Preheat the oven to 350 degrees F. Grease a 9-inch square baking dish. Set aside.
  • In a large mixing bowl, add dairy free milk, peanut butter, maple syrup, and vanilla. Whisk well to combine until no chunks of nut butter remain.
  • Into the same bowl, add oat flour, cocoa powder, flax, baking powder, and salt. Whisk to combine. Add chocolate chips and stir together.
  • Pour the oat mixture into the prepared baking pan. Using a spatula, gently smooth into an even layer. Top with more chocolate chips and dollops of more peanut butter swirled across if desired.
  • Place into the oven and bake for 40 to 50 minutes or until the edges are slightly browned. Remove from the oven and let it cool completely before cutting.
  • You can serve as-is or with toppings of your choice. Can be served warm or chilled. Store leftovers covered in the refrigerator for up to 5-7 days.

Notes

For the oats:  You can make this recipe with old fashioned (rolled) oats whole. If you do this your batter will be more liquidy than in the video, but it will still bake up great.  It is not easy to spread the peanut butter in swirls with this method. The ending result will be chewier. 
To make oat flour yourself: Simply dump the oats into a blender and pulse until a fine powder is left. Set aside.
For the peanut butter: If you want to do swirls on top, like in the video, please note that it’s not easy to do this with store bought peanut butter, unless it’s a looser, natural peanut butter.

    Made this today. Super easy to make and so good! I did not add the extra chocolate chips on top and just did a little more peanut butter to swirl around. I could eat the whole tray! LOL!!! Thank you for such a great recipe!

    1. Aww thank you! We’re so happy to hear that you enjoyed the recipe. Thank you for giving it a try!

    Easy, quick, delish! Thanks much! I did not use coco or chocolate chips simply because I did not have(I do plan to make again asap trying the chocolate though – same re: trying bannana). Meanwhile, I used stevia in place of maple syrup because I prefer no sugar anything where possible and I used natural, no sugar added peanut butter. I added just a very lil bit tumeric & ginger powder(just because I add to almost all I cook lol) Finally, I baked in my air fryer. It was delish and I will make again! I’m a strict vegan, with sever allergies(not nuts though thank my Lord:)) I truly appreciate your videos and recipes, you always make all very simple. I’ve been following you a few years or so now. God bless you and yours!🙂🙏🏾
