Ingredient Notes

The base ingredients for protein baked oatmeal are oats, milk, flax, banana and protein powder. From there you can experiment with add ins like nuts, berries, seeds or chocolate chips.

All the ingredients needed for making a vegan protein baked oatmeal recipe each in a small dish and labelled with text.

Here are a few notes on the basic ingredients:

  • Oats: I’d recommend large flake or rolled oats but quick oats are also suitable.
  • Milk: You can use any unsweetened non-dairy milk like almond milk, cashew milk or soy milk.
  • Ground Flax: You can use ground flax seeds or chia seeds for binding since the recipe does not contain eggs. We found flax to produce a firmer, more structured bar but both work well.
  • Banana: Use a ripe or slightly overripe banana.
  • Protein Powder: Use plant-based vanilla protein powder. Make sure you like the flavour before using as it will contribute to the overall flavour of the bars! You can substitute another protein flavour if you like.
  • Extras: Cinnamon, salt and vanilla extract are suggested for flavor but not required.

This list is not complete. Please see the recipe card at the end of the post for the complete ingredient list with measurements and detailed instructions.

Variations & Additions

There are many different ways to make protein baked oatmeal! Here are some ideas to customize the recipe:

  • Berries: Fresh or frozen berries of choice are recommended. You can use blueberries, blackberries, raspberries or sliced strawberries. Blueberry banana or strawberry banana is a good combo! Diced apples work well here too.
  • Chocolate Chip Baked Oats: Add up to 1/2 cup chocolate chips to the batter.
  • Maple Nut: Add 2 tbsp maple syrup and up to 1/2 cup chopped walnuts or pecans.
  • Carrot Cake: Add up to 1 cup finely grated carrot to the mixture. A pinch of ginger and nutmeg goes well here and you can consider other add-ins like walnuts, coconut or raisins.
  • Dried Fruit: Try raisins, cranberries, chopped apricots, dates or cherries.
  • Seeds: Try hemp seeds, sunflower seeds or pumpkin seeds.
  • Morning Glory: Add pumpkin seeds, carrot, raisins and walnuts.
  • Powdered Peanut Butter: Replace one scoop of the protein powder with 1/3 cup powdered peanut butter for peanut butter protein oats.
  • Additional Spices: Cinnamon is recommended but spices like ginger, nutmeg, cardamom and cloves all work well for flavor variations.

Step 4. Stir your choice of add-ins such as fresh or frozen berries or chocolate chips into the oat mixture, or leave them plain.

Bake for 30 minutes, let cool in the pan for 20-30 minutes to allow to firm into bars. This isn’t required but the bars will be firmer if you let them cool a while.

Expert Tips

  • Depending on if you flax or chia, you may find the bars are more or less firm. Either way, if you let them cool in the pan they’ll firm into a solid bar you can eat as a snack. If you don’t mind them a bit more mushy, you can slice from the pan right away.
  • If you’re using frozen berries, it’s suggested to sprinkle them over the top of the bars before baking and press them down a bit rather than mix them in.

  1. Do you have any suggestions for making these into a bar with more of a granola bar consistency? (soft/chewy or a little crunchy)

    1. It would be a whole different recipe sorry! I do have a baked granola bar recipe and a no-bake protein bar recipe but this recipe is just going to be soft and a little mushy, like oatmeal, haha. Thanks!
