How to Make Chocolate Peanut Butter Protein Baked Oatmeal:
- Preheat the oven to 350°F. Grease an 8×8 baking pan.
- In a large mixing bowl, mash the banana with the back of a fork until smooth and minimal lumps remain. Add milk, maple syrup, peanut butter, and vanilla and whisk until combined.
- Add oats, protein powder, cocoa powder, espresso powder, baking powder, and salt. Use a rubber spatula or wooden spoon to mix until combined. Pour oatmeal into prepared baking pan. (Optional): Sprinkle over chocolate chips.
- Bake for 25 minutes until top is set and edges start to pull away from pan. You’ll know when the oatmeal is done if it doesn’t jiggle or seem wet. Let cool for 5 minutes before slicing. I like to enjoy this oatmeal with a drizzle of creamy peanut butter!


Frequently Asked Questions
Can I substitute the peanut butter for another nut butter?
Sure! Feel free to substitute it with any other nut butter like cashew butter or almond butter.
Do I need to add the espresso powder?
You can omit it if you want, but the espresso powder doesn’t add a coffee flavor. Instead, it emphasizes and enhances the chocolate flavor.
What protein powder do you recommend?
My favorite is the Nuzest Chocolate Pea Protein Powder. It doesn’t have a chalky taste like other protein powders do and has no added or artificial sugars.
