Ingredients You’ll Need
The beauty of this Protein Baked Oats recipe lies in its simplicity, with each ingredient playing a specific role—whether it’s building texture, adding flavor, or boosting the protein content. These staples are easy to find and come together effortlessly to create a delicious and nourishing dish.
- 1 ¾ cup milk (dairy or plant-based): Provides creaminess and moisture to the batter, helping bind everything together.
- 3 large eggs (brought to room temperature): Essential for structure and that fluffy, cakey texture.
- 1 ½ teaspoon pure vanilla extract: Adds a delicate sweetness and aromatic depth.
- 1 cup mashed overripe bananas: Naturally sweet and moistens the oats perfectly, enhancing flavor and texture.
- ½ cup natural peanut butter: Brings richness and a nutty undertone while adding healthy fats.
- ½ cup maple syrup: A natural sweetener that balances the flavors beautifully.
- 3 cups old fashioned oats (rolled oats): The hearty base providing texture, fiber, and slow-release energy.
- ½ teaspoon salt: Elevates all the flavors, balancing sweetness and richness.
- ½ cup peanut butter powder: Boosts peanut flavor without extra oil, helping keep it lighter.
- ½ cup vanilla or unsweetened protein powder or collagen powder: The star ingredient for protein enrichment, tailor the sweetness by adjusting maple syrup if sweetened.
- ½ cup semi-sweet chocolate chips or carob chips (or blueberries): Adds bursts of indulgence or fresh fruitiness throughout.
- 2 tablespoons natural peanut butter: For the optional peanut butter drizzle topping—rich and luscious.
- 1 1/4 teaspoons melted coconut oil (divided): Helps create silky drizzles and slightly crispy edges on the baked oats.
- 2 tablespoons semi-sweet chocolate chips: For melting into a smooth chocolate drizzle that complements the peanut butter.
How to Make Protein Baked Oats
Step 1: Preheat and Prepare
Start by heating your oven to 350°F and greasing a 9 x 13-inch baking pan with non-stick cooking spray. This ensures your baked oats won’t stick and will come out cleanly, making cleanup a breeze.
Step 2: Combine Wet Ingredients
In a large bowl, whisk together the milk, eggs, vanilla extract, mashed bananas, peanut butter, and maple syrup until everything is smoothly combined. This mixture sets the creamy, flavorful foundation for your Protein Baked Oats.
Step 3: Add Dry Ingredients
Now, stir in the oats, salt, peanut butter powder, and protein powder. Whisk or stir well to break up any clumps, especially of the peanut butter powder, ensuring an even batter with a smooth consistency.
Step 4: Bake It
Pour the oatmeal batter evenly into your prepared pan, then sprinkle the chocolate chips over the top. Pop it in the oven and bake for 35 to 40 minutes. You’ll know it’s done when the center no longer jiggles and you see bubbles rapidly forming around the edges—a sign of perfect bake.
Step 5: Prepare the Optional Drizzle Toppings
While the baked oats are still warm, whip up the finishing touch: mix 2 tablespoons of natural peanut butter with 1 teaspoon of melted coconut oil until smooth for that rich peanut butter drizzle. In a separate small bowl, melt 2 tablespoons of chocolate chips with 1/4 teaspoon coconut oil in short bursts, stirring until silky. Drizzle both luscious toppings over the warm baked oats and get ready to indulge.
How to Serve Protein Baked Oats

Garnishes
To elevate your Protein Baked Oats even further, consider topping with extras like fresh sliced bananas, a sprinkle of chopped nuts for added crunch, or a handful of fresh berries for a juicy contrast. A dollop of Greek yogurt or a drizzle of honey can also add creamy or sweet notes that marry beautifully with the peanut butter and chocolate.
Side Dishes
This dish is pretty hearty on its own, but if you want to round out your breakfast or brunch, pair your Protein Baked Oats with a fresh fruit salad or a crisp green smoothie. Both bring freshness and a light balance to the richness of your baked oats.
Creative Ways to Present
Serve your Protein Baked Oats in individual ramekins for a charming, personalized feel, or cut it into rustic squares to make it easy to grab and go. You can also layer it with yogurt and granola for a decadent parfait-style breakfast that’s as delightful to look at as it is to eat.
Make Ahead and Storage
Storing Leftovers
Once cooled, store your Protein Baked Oats in an airtight container in the refrigerator. It keeps well for up to 4 days, making it a fantastic make-ahead breakfast option that can be reheated quickly for busy mornings.
Freezing
You can freeze individual portions by wrapping them tightly or placing them in freezer-safe containers. Frozen Protein Baked Oats will keep for up to 2 months. Just thaw overnight in the fridge before reheating for a convenient, ready-to-eat meal.
Reheating
To reheat, microwave your portion for 45 to 60 seconds until warmed through. For a crispier edge, heat in a preheated oven at 350°F for about 10 minutes. Add fresh toppings after reheating to bring back that fresh, just-made flavor experience.
FAQs
Can I use different nut butters instead of peanut butter?
Absolutely! Almond butter, cashew butter, or sunflower seed butter all make wonderful substitutions. Each will impart its own unique flavor, so feel free to experiment based on your preferences or dietary needs.
Is it possible to make this recipe vegan?
Yes! Use plant-based milk such as almond or oat milk and substitute the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) to keep the texture just right while making the Protein Baked Oats fully vegan.
Can I add fruit inside the baked oats?
Definitely! Chopped apples, berries, or even chunks of dried fruit fold beautifully into the batter for added bursts of sweetness and texture. Just be mindful of moisture content to keep the bake from becoming too soggy.
What type of protein powder works best?
Vanilla-flavored whey, plant-based protein powders, or collagen peptides work great here. Just keep in mind to adjust the sweetness depending on whether your protein powder is sweetened or not to balance flavors perfectly.
How can I make the baked oats less sweet?
Reduce the maple syrup gradually or switch to a natural sweetener like mashed dates or applesauce. The overripe bananas also add natural sweetness, so sometimes you can balance things out by lowering added sugars to suit your taste.
