Why You’ll Love Vegan Brownie Baked Oatmeal

Made this to bring into work for breakfast and it was a hit
Love that!
Made this for my post Pilates teaching treat! it is perfection of baked oatmeal! And I have tried a lot of recipes! I made it with powdered peanut butter because that’s all I had on the shelf. Added a splash of water. Super easy to make gluten-free of course!
So happy you enjoyed it!
Dying to try this but am missing 1 ingredient. I know this is supposed to be vegan but could I sub 1 egg for it this one time or is there another sub for the flax seed? Trying to avoid going back to the store right now.
Thank you either way!
Cheers,
Tricia
We don’t test with eggs (or eat them ourselves) so we truly have no idea how it would turn out to be able to let you know. Mashed sweet potatoes, pumpkin puree, or applesauce likely would do the trick
Do any adjustments need to be made if I want to put in protein powder?
Yes, because protein powder absorbs liquid. I would start by reducing the oats or adding 2–4 tbsp extra plant milk. Add your protein powder gradually and adjust the texture so it stays thick.
Second time making these and they’re fantastic! I pre-portioned them by scooping the batter into my 9-slot mini-loaf pan and asking for @20 minutes. Also, I have found that allowing the oat flour to hydrate 5-10 minutes before putting into baking dish helps absorb some of the liquid so it’s easier to portion.
I love that!
This is so moist! I subbed almond butter and chopped 1/2 85% dark chocolate bar because I was out of chocolates chips. Breakfast, lunch or serve it warmed up with maple syrup for dessert! Love love ❤️
So happy you love it
Hello!
Mine also came out straight liquid. It worked out in the end, but it made me think I wouldn’t before putting it in the oven! 🙂 I followed the weight measurements instead of cups, but I suppose it should be equivalent.
Another thing I have noticed is that mine looks much lighter than the one in the pictures. Could it be my choice of cocoa powder? Or do you have any other tips?
Other than that… Thank you so much for this recipe! It’s very light and really good!
Glad you like it! Cocoa powder color could totally make the difference.
