Vanilla Protein Baked Oatmeal


This vanilla protein baked oatmeal is hands down one of my favorites. The addition of the vanilla protein and almond extract makes it resemble a sugar cookie! It’s sweetened with bananas, packed with protein, and even gluten-free, dairy-free, and egg-free for anyone that needs it. The ingredients are simple and easy, and it comes together in a pinch! You get to cook once and have breakfast waiting for you for the next few days!

What is baked oatmeal?

Baked oatmeal is oatmeal baked in the oven making breakfast incredibly easy. You can make it ahead so that all you have to do is warm it in the morning or eat it straight from the fridge (which I often do)! It’s a great simple breakfast or snack option. It tastes like dessert, and it’s just so delicious!

What you need to make vanilla protein baked oatmeal + substitutions:

  • Quick oats- I love using quick oats, because it gives it the best texture! This is my absolute favorite way to make baked oatmeal, because it makes it dense and brownie-like. You can substitute with rolled oats, which will make it a little more chewy but still fabulous!! Steel cut oats won’t work for this!
  • Cashew milk- Feel free to substitute with another milk like cashew, soy, oat, dairy or whatever you prefer!
  • Banana- The mashed banana gives it a little sweetness as well as making it nice and soft. You want to make sure they’re nice and spotty and brown, because that will give it the perfect sweetness.
  • Vanilla protein– I used Nuzest vanilla protein (you can use the lex for 15% off), because I love this one! You can use any protein powder, but mine does add a little sweetness so that’s why I skipped any sweeteners this time. Four scoops measures out to be about 1/2 cup.
  • Baking powder- Baking powder helps the oatmeal to rise.
  • Cinnamon– I just love cinnamon in any baked recipe. This just adds a nice little touch!
  • Almond extract- You can certainly substitute with vanilla extract, BUT I would highly suggest the almond. It gives it a sugar cookie flavor and it’s absolutely insane. Really changes everything!
  • Sea salt- I don’t bake anything without salt. It’s what helps bring the flavor out in a recipe.

Tips for making:

  • Quick oats vs rolled oats- Like I said above, quick oats will give it a denser, more brownie-like texture and is what I personally prefer. Rolled oats will still work, but they will create a more crumbly texture.
  • For the best texture- You want to make sure the vanilla protein baked oatmeal is still soft in the center, but cooked through. That way it comes out nice and soft.
  • I don’t think this recipe would work without the protein powder! You could try substituting with something else if you’d like, but I have not tested it. The protein really helps to soak up the liquid and hold everything together! If you’re looking for a baked oatmeal without protein powder, I have a TON of other options!

    This was great! I had some bananas and quick oats to use up and it was perfect. I’m working with a dietician who wants me to get my protein and this was an easy way to add it in. I’m gonna try adding more mix ins next time. Also thank you for the freezer instructions!
