Protein Baked Oatmeal is an easy meal prep option, but it's not always delicious if you rely on protein powder alone. This version includes several sources of protein for a flavor you'll love.
Preheat the oven to 350ºF and lightly grease an 8-inch square pan with oil. Press a piece of parchment paper into the bottom of the pan to ensure easy removal later. (This also makes cleanup easier!)
Add the banana to a large mixing bowl and use a fork to mash it until it looks like puree. Then add in the rolled oats, protein powder, baking powder, cinnamon, salt, eggs, yogurt, milk, and maple syrup. Stir well until you see no large lumps in the batter.
Pour the mixture into the prepared pan and spread it out evenly. Then top with chopped pecans, if desired. (Or any other mix-ins you love.) Bake at 350ºF for 35 to 40 minutes, or until the center feels firm to the touch. Note: A metal pan usually bakes faster than a glass or ceramic one.
Remove the pan from the oven and let the oatmeal cool for at least 20 minutes before slicing and serving. I like to cut it into six larger slices for meal prep, but you can also cut it into nine squares for brunch. Add a dollop of yogurt and fresh fruit to serve, if desired.
Notes
Nutrition information is for 1 of 6 slices, including the pecan topping. This information is automatically calculated using generic ingredients in a database, so it's just an estimate not a guarantee. Protein Powder Note: I tested this recipe with unsweetened Garden of Life plant-based protein powder and unflavored collagen peptides. If you're hoping for muscle growth, the protein powder is likely to have a more complete amino acid profile, so I recommend starting with that option, rather than collagen. You can taste this type of protein powder slightly in this recipe, so if you prefer ZERO flavor, try using 1/3 cup of collagen peptides instead. Greek Yogurt Note: Be sure to read the label when shopping for Greek yogurt. Some brands have significantly more protein than others. Don't love bananas? You can omit the banana and increase the maple syrup to a 1/2 cup total in this recipe. The flavor is great that way, too!
