Ingredients You’ll Need

The beauty of Protein Baked Oats lies in how a handful of pantry staples work together to make a breakfast you’ll truly look forward to. Every ingredient is purposeful, bringing in nuttiness, natural sweetness, and that irresistible soft-baked texture.

Milk (1 ¾ cup): Choose dairy or your favorite plant-based alternative; it provides moisture and richness.
Eggs (3 large, room temperature): Vital for binding everything together and adding a boost of protein.
Pure Vanilla Extract (1 ½ teaspoon): Adds warmth and depth, making everything taste even more homemade.
Mashed Overripe Bananas (1 cup): Naturally sweetens the oats and brings moisture for the perfect fluffy bite.
Natural Peanut Butter (½ cup): Lends creamy texture, nutty flavor, and extra protein power.
Maple Syrup (½ cup): For a gentle sweetness that doesn’t overpower the other flavors. Subtle, but so necessary!
Old Fashioned Oats (3 cups): Go for rolled oats; they bake up soft and hearty, holding all the goodness together.
Salt (½ teaspoon): Enhances sweetness and balances the nutty richness.
Peanut Butter Powder (½ cup): Concentrates that classic PB flavor while amping up the protein.
Protein Powder or Collagen Powder (½ cup): Pick vanilla or unsweetened for the protein boost; adjust maple syrup if using a sweetened kind.
Semi-Sweet Chocolate Chips or Blueberries (½ cup): Gives pockets of melty, chocolatey joy in every bite—or swap in juicy blueberries for a fruity variation.
Optional Toppings – Natural Peanut Butter, Melted Coconut Oil, Semi-Sweet Chocolate Chips: Perfect for that extra drizzle that looks gorgeous and tastes even better.

How to Make Protein Baked Oats

Step 1: Preheat and Prep Your Pan

Set your oven to 350°F, and grab a 9 x 13-inch baking pan. Give it a good misting with non-stick cooking spray, ensuring your Protein Baked Oats release beautifully after baking. This makes cleanup a total breeze, too.

Step 2: Mix the Wet Ingredients

In a big mixing bowl, whisk together your milk, eggs, vanilla, mashed bananas, peanut butter, and maple syrup. This creates a creamy, luscious base that infuses the oats with richness and natural sweetness. Take a moment to inhale that comforting aroma—this is where the magic starts!

Step 3: Add the Dry Ingredients

Sprinkle in your old-fashioned oats, salt, peanut butter powder, and protein powder. Grab your whisk and combine until everything is just mixed and the peanut butter powder clumps dissolve. This step is key for ensuring even distribution of the protein throughout your baked oats.

Step 4: Pour and Sprinkle

Pour your oatmeal batter into the prepared baking pan and smooth the top gently. Now comes the fun part: shower those chocolate chips (or blueberries!) all over the surface, ensuring delightful pools of flavor in every bite.

Step 5: Bake to Perfection

Slide your pan into the oven and bake for 35–40 minutes. Watch for the center to set (no more jiggles) and the edges to bubble enticingly; this is your cue that the Protein Baked Oats are almost ready! Let it cool on a wire rack for a few minutes to make slicing easier.

Step 6: Add the Optional Peanut Butter & Chocolate Drizzle

If you’re in the mood for a decadent finish, whisk natural peanut butter with some melted coconut oil until velvety! For the chocolate drizzle, melt chocolate chips with coconut oil in short microwave bursts, then swirl both over the still-warm baked oats for a swoon-worthy finish. Serve and enjoy while it’s gorgeously melty and fresh!

How to Serve Protein Baked Oats

Garnishes

Fresh from the oven, you can get creative with your toppings! Drizzle extra peanut butter, a scatter of chopped peanuts for crunch, or even sliced bananas for extra sweetness. If using the chocolate drizzle, let it drip down the sides for a stunning bakery-style look.

Side Dishes

Protein Baked Oats are filling on their own, but a side of Greek yogurt, a handful of mixed berries, or even a cold glass of milk complements the hearty flavors and rounds out your breakfast. For a lighter touch, serve alongside a simple fruit salad.

Creative Ways to Present

Try scooping the still-warm oats into little ramekins with a dollop of yogurt and fruit on top, or slice into bars for an easy, meal-prepped breakfast on the go. You can even transform them into dessert by topping with a scoop of frozen yogurt and an extra drizzle of chocolate.

Make Ahead and Storage

Storing Leftovers

Once your Protein Baked Oats have cooled completely, slice them into squares and store in an airtight container in the fridge. They’ll stay moist, tender, and delicious for up to 4 days, making weekday breakfasts as easy as reaching in and grabbing a piece.

Freezing

Want to meal prep for longer? These oats freeze wonderfully! Just wrap individual squares tightly in plastic wrap or foil, then pop them in a freezer-safe bag. They’ll keep their flavor and texture for up to 2 months—simply thaw overnight in the fridge before enjoying.

Reheating

For the best texture, reheat Protein Baked Oats in the microwave for 30 to 60 seconds, or in a 350°F oven for about 10 minutes. Splash on a little extra milk before reheating if you love them extra moist and tender. Top with more peanut butter for the ultimate treat!

FAQs

Can I use quick oats instead of old-fashioned oats?

Old-fashioned oats give Protein Baked Oats their hearty texture, but you can substitute quick oats in a pinch; just know your bake will turn out a tad softer and less chewy.

What type of protein powder works best?

Both whey and plant-based protein powders work wonderfully here. Vanilla adds subtle flavor, but unflavored or collagen are great options. If using sweetened protein powder, remember to slightly reduce the maple syrup to keep things balanced.

How can I make it nut-free?

Substitute sunflower seed butter for the peanut butter, and use a nut-free protein powder. The result will still be creamy, rich, and delicious, so everyone can enjoy Protein Baked Oats!

Can I prepare the batter in advance?

Yes! You can mix the batter (minus the chocolate chips) and store it in the fridge overnight. In the morning, give it a quick stir, sprinkle on the chocolate chips, and bake as usual.

How do I know when the baked oats are finished baking?

Your Protein Baked Oats are ready when they no longer jiggle in the center and the edges are bubbling. A clean toothpick inserted into the middle should come out mostly clean with just a few moist crumbs.

Final Thoughts

If you’re looking for a breakfast that’s cozy, protein-packed, and feels like an indulgence, you absolutely need to give Protein Baked Oats a try. It’s a recipe that’s easy to make, endlessly adaptable, and sure to put a smile on your face as you start your day. Enjoy every nourishing, chocolate-drizzled bite!
