Gathering simple, wholesome ingredients is key to making this recipe a standout.

2 cups old fashioned oats: Use these for chewy texture and nutty flavor; they hold up well when baked.
1/3 cup unsweetened cocoa powder: Adds rich chocolate taste without overpowering sweetness.
1 teaspoon baking powder: Helps the oatmeal rise slightly, keeping it light and tender.
1/2 teaspoon kosher salt: Balances sweetness and enhances all flavors.
1 cup mashed ripe bananas (about 2 large bananas): Adds natural sweetness and moisture for a soft crumb.
1 cup unsweetened vanilla almond milk (or milk of your choice): Moisturizes the oats and adds subtle vanilla warmth.
1/2 cup creamy natural peanut butter: Infuses the dish with creamy nuttiness and protein.
2 large eggs: Bind everything together for a custardy baked texture.
1/4 cup pure maple syrup: Offers gentle sweetness with a hint of caramel complexity.
1 1/2 teaspoons pure vanilla extract: Enhances the pockets of chocolate and peanut butter flavors.
1/2 cup chocolate chips (divided): Melts into little pockets of gooey chocolate bliss.

How to Make Chocolate Peanut Butter Baked Oatmeal Recipe

Step 1: Preheat and prep your pan

Start by preheating your oven to 350 degrees Fahrenheit. Lightly grease an 8×8-inch baking dish with nonstick spray to ensure your oatmeal comes out easily. Trust me, a little prep here saves a lot of cleanup later.

Step 2: Mix your dry ingredients

In a large bowl, whisk together the oats, unsweetened cocoa powder, baking powder, and kosher salt. This combination forms the flavorful base of your baked oatmeal, packing it with chocolatey goodness and the right amount of lift and seasoning.

Step 3: Combine the wet ingredients

In a separate medium bowl, mash your ripe bananas and add the almond milk, creamy peanut butter, eggs, maple syrup, and pure vanilla extract. Whisk everything until smooth and well combined. This wet mixture brings moisture, sweetness, and that irresistible peanut butter richness to the dish.

Step 4: Bring everything together

Pour the wet ingredients into the bowl with your oat mixture. Stir gently until everything is fully combined. Then fold in 1/4 cup of the chocolate chips to pepper the batter with creamy gooeyness.

Step 5: Bake your masterpiece

Transfer the oatmeal mixture to your prepared baking dish and smooth the surface. Sprinkle the remaining chocolate chips evenly over the top for an extra melty chocolate finish. Bake for about 35 minutes, or until the oatmeal is set in the center and the edges are lightly firm.

Step 6: Cool and serve

Allow the baked oatmeal to cool in the pan for 5 minutes, giving it time to firm up so it cuts into beautiful squares. For an extra special touch, drizzle with a bit of peanut butter and sprinkle flaky sea salt if you like a salty-sweet contrast.

Garnishes

Topping your Chocolate Peanut Butter Baked Oatmeal Recipe transforms it into a truly indulgent breakfast. Fresh fruit like bananas or strawberries adds brightness and freshness, while a drizzle of warm peanut butter or a dollop of Greek yogurt provides creaminess and extra richness. Don’t forget a sprinkle of flaky sea salt for a little savory pop!

Side Dishes

This baked oatmeal pairs beautifully with simple sides that balance its sweetness. Consider a small bowl of mixed berries or a crisp green salad if serving as a brunch centerpiece. For a heartier meal, crispy bacon or turkey sausage links add savory contrast that’ll have you craving every bite.

Creative Ways to Present

Try serving this Chocolate Peanut Butter Baked Oatmeal Recipe as individual portions by baking in a muffin tin for grab-and-go breakfasts. Or, cut it into squares and layer with yogurt and granola parfait-style for beautiful presentation and added texture. Another fun idea is to warm each square and sandwich it with sliced bananas and peanut butter for a breakfast “oatmeal sandwich.”

Make Ahead and Storage

Storing Leftovers

Store leftover baked oatmeal in an airtight container in the refrigerator for up to 5 days. This allows the flavors to deepen, making each reheat taste even better than the first morning. Just cover well to avoid drying out.

Freezing

This recipe freezes wonderfully, making it a perfect meal prep option. Cut the cooled oatmeal into squares and freeze them in a single layer on a baking sheet. Once frozen, transfer to a freezer bag and store for up to 3 months.

Reheating

To enjoy leftovers, reheat single servings in the microwave for about 45 seconds to 1 minute until warmed through. You can add a splash of milk before reheating to keep it moist and creamy. For a crispier edge, reheat in a toaster oven at 350 degrees for 10 minutes.

FAQs

Can I use quick oats instead of old fashioned oats?

While quick oats can technically be used, old fashioned oats provide better texture and structure for this baked oatmeal. Quick oats might result in a softer, less chewy finished dish.

Is there a way to make this recipe vegan?

Absolutely! Replace the eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and use a plant-based milk and vegan chocolate chips to make this recipe friendly for a vegan diet.

What can I substitute for peanut butter?

You can swap peanut butter with almond butter, cashew butter, or sunflower seed butter for a different nutty flavor. Just make sure the consistency is creamy to blend smoothly into the batter.

How sweet is this baked oatmeal?

This recipe has a moderate sweetness thanks to the mashed bananas and maple syrup. It’s sweet enough to satisfy your morning sweet tooth without overpowering, but you can always add a little more maple syrup if you prefer.

Can I add any mix-ins?

Definitely! Chopped nuts, shredded coconut, or dried fruit would be delicious additions. Just fold them into the batter before baking to customize your Chocolate Peanut Butter Baked Oatmeal Recipe.
