Plus, it’s naturally gluten-free, oil-free, and vegan! 

Ingredients You’ll Need + Substitutions

• Oats: ​In all of our baked oatmeal recipes, we recommend using old-fashioned oats or rolled oats. They yield better oat flour than oats such as steel-cut oats or quick oats and will create the best textured baked oatmeal. If you’re interested in reading about the different varieties of oats, check out our Easy Apple Cinnamon Oatmeal blog post. We go into depth in the post on the top 5 types of oats. If you are gluten-free, make sure to use certified gluten-free oats.
• Protein powder: Any protein powder of choice will work here. Try vanilla protein powder, chocolate peanut butter protein, or chocolate protein powder for a double chocolate baked oatmeal dish. Avoid whey protein powder or protein powders that contain milk or egg whites. These protein powders are not vegan protein sources. 
• Silken tofu: ​Adding silken tofu to our recipes is one of our favorite tricks for adding additional protein without affecting taste or texture. If you’re not a tofu lover – don’t worry. The taste doesn’t come through at all. For more sneaky ways to boost protein in recipes, check out our Roasted Red Pepper Pasta Sauce, Vegan Buffalo Chicken Dip, or this Silken Tofu Chocolate Mousse.
• Almond milk: Opt for your favorite homemade or store-bought plant-based milk. Cashew milk, soy milk, or coconut milk are alternate favorites. 
• Peanut butter: ​For the best, moist textured baked oatmeal, you want to use a runny, creamy natural peanut butter. If desired, you can also use another nut butter such as almond butter, cashew butter, or sunflower seed butter for a nut-free variety. 
• Banana: Ripe banana adds sweetness, and moisture, and helps keep the oatmeal bake soft. If you’re out of ripe bananas, substitute in about 1/2 cup of unsweetened applesauce (adjust depending on how dry your oatmeal bake looks)
• Flaxseed meal: A flax egg is one of our favorite egg substitutes in vegan baking. If you’re out of ground flaxseed meal, opt for chia seeds. 

Equipment Needed

• Small baking dish (7×9.5-inches) 
• Oil or cooking spray, for greasing the dish
• High-speed blender
• Spoon or spatula

How to Make Protein Baked Oatmeal 

1. Make oat flour. Add the rolled oats into a high-speed blender and process until the oats are a fine flour consistency, about 30 seconds. 
2. Add remaining ingredients. ​Once the oats are blended into a flour-like consistency, add in the protein powder, silken tofu, almond milk, peanut butter, banana, flaxseed meal, maple syrup, baking soda, baking powder, cinnamon, and salt. Blend until smooth. 
3. Transfer to a baking dish. Pour the baked oatmeal batter into the prepared baking dish along with all but 1 tablespoon of the chocolate chips and peanuts. Mix the batter and chocolate chips and peanuts together by hand using a spoon or baking spatula. Once well combined, spread the oatmeal batter until smooth in the baking dish. Sprinkle the remaining chocolate chips and peanuts on top, as desired. 
4. Bake. Bake the protein oats for 25 to 30 minutes or until a toothpick inserted in the middle comes out clean. 
5. Cool and serve. Allow the protein baked oatmeal to cool for about 5 minutes, then serve as desired.
