Ingredients You’ll Need

To make this Peanut Butter Banana Baked Oatmeal come to life, you only need a handful of simple, wholesome ingredients. Each one plays a special role, from adding richness and moisture to bringing out natural sweetness and that perfect baked texture.

• 1 large spotty banana (mashed): provides natural sweetness and a creamy base for the oatmeal.
• ½ cup creamy all-natural peanut butter: choose a runny version for easy mixing and that nutty, rich flavor.
• 3 tbsp real maple syrup (or honey): adds an extra touch of natural sweetness and helps with caramelization.
• 1 ¾ cups unsweetened almond milk or oat milk: keeps the oatmeal moist and dairy-free while adding subtle creaminess.
• 1 large egg (or 1 tbsp ground flaxseed + 3 tbsp warm water for vegan option): binds everything together for the perfect bake.
• 2 tsp vanilla extract: brings warm, fragrant notes that complement the peanut butter and banana beautifully.
• 2 cups old-fashioned rolled oats (200g): provide wholesome texture and fiber-packed goodness.
• 1 tsp ground cinnamon: gives a comforting spicy touch that elevates the flavors.
• 1 tsp baking powder: helps the oatmeal rise just enough to keep it light and tender.
• ½ tsp salt: enhances all the natural flavors without overpowering.

How to Make Peanut Butter Banana Baked Oatmeal

Step 1: Preheat and Prepare Your Baking Dish

Start by heating your oven to 350°F (175°C) and greasing an 8×8-inch baking dish lightly with oil or butter. This ensures your baked oatmeal will come out cleanly without sticking while getting those lovely browned edges.

Step 2: Mix the Wet Ingredients

In a large bowl, mash the ripe banana until smooth. Stir in the creamy peanut butter and maple syrup until evenly combined. Next, whisk in the almond milk (or oat milk), egg (or flaxseed mixture), and vanilla extract. This wet mixture sets the stage for a luscious, flavorful bake.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together the rolled oats, cinnamon, baking powder, and salt. This combo gives your oatmeal structure, subtle spice, and helps it rise gently for a fluffy texture.

Step 4: Bring Wet and Dry Together

Pour the wet ingredients into the dry bowl and gently stir until all the oats are coated and the batter looks uniform. Don’t overmix—just make sure everything is combined. You’re aiming for thick, moist batter that’s bursting with flavor.

Step 5: Bake to Perfectness

Transfer the mixture into your prepared baking dish, spreading it evenly. Bake uncovered in the preheated oven for 30 to 35 minutes. You’ll know it’s ready when the top is golden, the edges are set, and a toothpick inserted near the center comes out mostly clean.

Step 6: Let It Cool Slightly Then Enjoy

Allow the baked oatmeal to cool for about 5 to 10 minutes before slicing. This rest time lets it firm up just enough so the pieces hold together beautifully on your plate.

How to Serve Peanut Butter Banana Baked Oatmeal

Garnishes

To really elevate your Peanut Butter Banana Baked Oatmeal, consider topping it with sliced bananas, a drizzle of additional peanut butter, a sprinkle of chopped nuts, or a dash of cinnamon. Fresh berries or a swirl of Greek yogurt can also add an inviting freshness that balances the warm, nutty notes.

Side Dishes

Pairing this baked oatmeal with a simple cup of your favorite coffee or chai tea creates a comforting morning meal. If you want something extra, a side of fresh fruit salad or a smoothie complements the richness with a bright, juicy contrast.

Creative Ways to Present

Serve your Peanut Butter Banana Baked Oatmeal in small ramekins for individual portions. You can also scoop it into mason jars for a grab-and-go breakfast or pack it as a nourishing snack. For an indulgent twist, consider topping it with a scoop of vanilla ice cream for dessert-worthy warmth any time of day.

Make Ahead and Storage

Storing Leftovers

This baked oatmeal keeps beautifully in the fridge for up to 4 days. Store leftovers in an airtight container to maintain moisture and freshness. It’s perfect for busy mornings—you just reheat and enjoy.

Freezing

If you want to keep it longer, Peanut Butter Banana Baked Oatmeal freezes wonderfully. Slice it before freezing and separate slices with parchment paper in a freezer-safe bag. When ready to eat, simply thaw overnight in the fridge or reheat directly from frozen, adding a bit more time.

Reheating

Reheat slices in the microwave for about 45 to 60 seconds or until warm throughout. For a crispier edge, pop a slice under the broiler for a couple of minutes. Either way, it’s just as delightful as when freshly baked.

FAQs

Can I make Peanut Butter Banana Baked Oatmeal vegan?

Absolutely! Simply replace the egg with a flaxseed “egg” by mixing 1 tablespoon of ground flaxseed with 3 tablespoons of warm water and letting it sit for a few minutes until gel-like. Use plant-based milk as you normally would, and you’re all set.

What kind of peanut butter works best?

For smooth mixing and rich flavor, creamy, all-natural peanut butter that is slightly runny works best. Avoid overly thick or chunky peanut butter unless you want extra texture; just remember to adjust mixing accordingly.

Can I substitute the oats with gluten-free oats?

Yes, gluten-free rolled oats are a perfect swap if you need this recipe to be gluten-free. Just make sure to use certified gluten-free oats to avoid cross-contamination if you have a sensitivity.

How ripe should the banana be for best flavor?

Your banana should be spotty or even a bit more ripe than usual—it guarantees more natural sweetness and a softer texture that blends smoothly into the baked oatmeal.

Is it possible to add mix-ins like chocolate chips or nuts?

Definitely! Adding chocolate chips, chopped nuts, or seeds can add delightful bursts of flavor and texture. Stir them in the batter before baking or sprinkle on top for a visually appealing finish.
