Ingredients You’ll Need

The magic behind this Peanut Butter Baked Oatmeal is in its simplicity. Each ingredient plays a vital role, from adding creamy texture to bringing a hint of sweetness or just the right touch of spice. These staples create a dish that is as easy to prepare as it is delicious.

• Banana (1 large, spotty, mashed): Provides natural sweetness and moisture, binding the ingredients together beautifully.
• Creamy all-natural peanut butter (½ cup): The heart of the dish, lending a rich, nutty flavor and luscious creaminess.
• Real maple syrup (3 tbsp): Adds a subtle, natural sweetness that complements the peanut butter perfectly.
• Unsweetened almond milk or oat milk (1 ¾ cups): Keeps the oatmeal moist and adds a slight nuttiness without overpowering.
• Large egg (1) or ground flaxseed with warm water (vegan option): Acts as a binder, helping the oatmeal set firmly after baking.
• Vanilla extract (2 tsp): Enhances all the flavors with a warm, fragrant note.
• Old-fashioned rolled oats (2 cups / 200g): The wholesome base for the oatmeal, providing a chewy, satisfying texture.
• Ground cinnamon (1 tsp): For that cozy warmth and gentle spice that pairs beautifully with peanut butter.
• Baking powder (1 tsp): Helps the oatmeal to rise slightly for a perfect, fluffy consistency.
• Salt (½ tsp): Balances the sweetness, making the flavors pop just right.

How to Make Peanut Butter Baked Oatmeal

Step 1: Preheat and Prepare

Start by heating your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish with cooking spray or a touch of avocado oil to prevent sticking and ensure easy serving later on.

Step 2: Mix the Wet Ingredients

In a large bowl, mash the ripe banana until smooth. Add the creamy peanut butter, real maple syrup, almond or oat milk, the egg (or your flaxseed alternative), and vanilla extract. Whisk these together until you have a smooth, homogenous mixture that promises rich flavor in every bite.

Step 3: Incorporate the Dry Ingredients

Next, stir in the rolled oats, ground cinnamon, baking powder, salt, and if you opted out of the egg, the flaxseed mixture. Mix everything until just combined, but don’t over stir. Keep an eye on your batter’s texture — different peanut butter brands vary in thickness, so if it feels too stiff, simply add a little extra milk to reach the perfect consistency.

Step 4: Transfer to Baking Dish

Pour the oatmeal batter into your greased dish, spreading it evenly with a spatula. Smooth the top gently; this helps it bake evenly and develop a beautiful golden crust.

Step 5: Bake to Perfection

Bake for 35 to 45 minutes. You want the top to be golden brown and the center to set firmly without being dry. The aroma at this point will be utterly irresistible!

Step 6: Cool and Get Ready to Savor

Once out of the oven, let your Peanut Butter Baked Oatmeal cool for about 5 minutes. This helps it set further and makes it easier to slice and serve. If you’re feeling fancy, drizzle a little extra peanut butter on top or add some fresh banana slices—both elevate the experience beautifully.

Make Ahead and Storage

Storing Leftovers

Any leftovers from your Peanut Butter Baked Oatmeal can be refrigerated in an airtight container for up to 4 days. Keeping it chilled helps maintain freshness and makes reheating a breeze.

Freezing

This baked oatmeal freezes exceptionally well. Slice it into portions before freezing, wrap each piece tightly in plastic wrap, and place in a freezer-safe container or bag. It stays delicious for up to 3 months, making it perfect for meal prep or busy mornings.

Reheating

When you’re ready to enjoy leftovers, microwave individual slices for about 45 seconds to 1 minute or warm them in a preheated oven at 350°F (175°C) for 10-15 minutes. Adding a splash of milk before reheating keeps the oatmeal moist and creamy.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add a delightful texture to the baked oatmeal. Just be aware it might affect the batter’s consistency slightly, so you might need a bit more liquid to balance it out.

Is it okay to substitute the banana with applesauce?

Yes, applesauce is a great alternative if you don’t have a ripe banana. It provides similar moisture and natural sweetness, though the flavor profile will be milder compared to using banana.

Can I make this recipe gluten-free?

Definitely. Just make sure to use certified gluten-free rolled oats, and you’ll have a safe, gluten-free Peanut Butter Baked Oatmeal that’s just as delicious.

How do I make this recipe vegan?

To make the Peanut Butter Baked Oatmeal vegan, simply replace the egg with 1 tablespoon of ground flaxseed mixed with 3 tablespoons of warm water and allow it to thicken. Use maple syrup instead of honey, and opt for plant-based milk like almond or oat milk.

Can I add chocolate chips or other mix-ins?

Yes, adding chocolate chips, dried fruit, or nuts can make this recipe even more exciting. Just fold them gently into the batter before baking to distribute evenly without weighing it down.
