Whole Oats

Oats offer carbs and fiber, which give you energy and keep you full- a great way to start the day! In this oatmeal recipe, whole oats are ground in a blender or food processor to create oat flour. You can also skip this step by buying oat flour from the store if you’d like!

Bananas are a great source of potassium and fiber, which is beneficial for gut health. They also add natural sweetness and creaminess to the recipe. If you don’t have bananas, you can substitute applesauce or pumpkin puree, but you may need to add another sweetener like honey.

Baking Powder

Baking powder is a leavening agent that helps the oats rise and become fluffy. If you don’t have baking powder, you can substitute baking soda. If you do, make sure you add an acid like lemon juice or yogurt to activate the baking soda.


Salt is a necessary ingredient in any baked good to balance out the sweetness and help enhance the flavor of the other ingredients. You can substitute sea salt or pink Himalayan salt for regular table salt.


Eggs are a great source of protein. They also help bind all the ingredients together and make the oats fluffy. If you’re vegan or have an egg allergy, you can use a flax or chia seeds as an egg substitute.

Vanilla Extract

Vanilla extract adds a delicious flavor to the recipe, but you can substitute almond or other extracts.

Almond Milk

If you’re looking for non-dairy milk to use in this recipe, Almond milk is a great dairy-free alternative to cow’s milk. It has a similar consistency to skim milk and can be used in almost any recipe in place of it. You can also use soy milk, cashew milk, or oat milk.

Maple Syrup

Maple syrup is a natural sweetener that adds a delicious flavor to this recipe. You can also substitute honey, agave nectar, or brown sugar.

Protein Powder

Many people wonder if you can cook with protein powder, and the answer is absolutely! The best type of protein for this recipe is whey as it doesn’t dry out the recipe.

If you are vegan, substitute this ingredient with a vegan protein powder of your choice. If you’re using a plant-based protein powder, I recommend adding 1 tbs of olive oil to the recipe.
