Peanut Butter Cookie Baked Oatmeal: rich in fiber, protein, and healthy fats to keep you full + fueled! Topped with a peanut butter “frosting” and fresh raspberries, these baked oats for one are a breakfast win. Baked oats for one in a ramekin topped with peanut butter and raspberries

This breakfast is 100% conducive to a rushed morning. Just mix all ingredients, pour in a ramekin, place in the oven and carry on with morning to-dos while it bakes. Once your kitchen starts smelling like peanut butter cookies, you’ll know it’s go time.

I love experimenting with different add-ins for baked oatmeal. Much like my Chai Spiced Baked Oatmeal, the combination of different spices, fruit, and nuts are endless.

To really round out the “cookie” experience in these oats, I top them with a peanut butter “frosting” and fresh berries. Alternatively, you can add a dollop of Greek yogurt, banana slices, and/or drizzle of maple syrup

Either way, these baked oats for one really lend the “dessert for breakfast” experience. Which is how I wish to start every day!

How to Make Peanut Butter Baked Oatmeal

This is the kind of recipe that you’ll fall asleep feeling excited about eating the next day.

For sweetness, I add just a touch of maple syrup to the batter. As the recipe is written, this baked oatmeal recipe isn’t super sweet, which is just how I like it. If you’d like your oats sweeter, you can add a bit more maple syrup to the recipe or simply drizzle some on at the end.

The IngredientsRecipe ingredients in separate bowls with labels

  • Oats: An excellent source of whole grains and fiber, oats make for a satisfying, satiating breakfast. I do not suggest using quick oats or steel-cut oats for this recipe. 
  • Egg: Not only does the egg add protein, but it also acts as the binder for these oats. If making the recipe vegan, you can use a flax egg instead. 
  • Peanut Butter: Look for a natural creamy peanut butter that only contains peanuts + salt.
  • Milk: Use any milk you prefer in this recipe. I prefer an unsweetened plant milk, such as cashew or almond. However, 2% or whole cows milk also works great.
  • Maple Syrup: A little maple syrup goes into both the batter and the frosting. If you prefer your oats sweeter, feel free to drizzle a little extra over the oats once they’re baked.
  • Vanilla: For the real peanut butter cookie experience, vanilla extract is a must.
  • Optional Add-Ins: Add extra protein to this peanut butter baked oatmeal by adding 1 to 2 Tbsp. of collagen powder or your protein powder. You can also add powdered peanut butter for extra PB flavor. 

The Directions

Step 1. Blend Ingredients

Preheat oven to 350ºF.

In a blender or nutribullet, combine oats, milk, egg, peanut butter, maple syrup, vanilla, and a pinch of sea salt. Pulse a few times until ingredients are combined, but there are still some chunks of oats. (The batter should not be totally smooth.)oats, milk, egg, and peanut butter being blended in a Nutribullet

Step 2: Bake Oats

Pour batter into a greased 6-oz. ramekin or large mug. Carefully place in the oven and bake for 25 to 30 minutes, until the edges are set and center is slightly giggly. Remove from oven and let sit for 5 minutes.Oat batter poured into a white ramekin

Step 3: Top with Peanut Butter Frosting

Meanwhile, combine 1 Tbsp. peanut butter, 2 tsp. milk, and 1 tsp. maple syrup in a small bowl; mix until smooth. Gently spoon frosting over baked oats, and garnish with fresh berries or banana slices. Peanut butter baked oatmeal topped with frosting and raspberries

Are Baked Oats Good for You?

Thanks to fiber-filled whole-grain oats, protein-rich eggs (which act as a binder), and healthy fats from nut butter, baked oatmeal is ultra filling and nutritious.

To make baked oatmeal even more satiating, add a scoop of collagen peptides or your favorite protein powder.

How Long Does Baked Oatmeal Keep?

Baked oatmeal will last up to 3 days refrigerated. To reheat, simply nook it in the microwave and add your toppings of choice. You can also enjoy baked oatmeal chilled.
