Why You’ll Love Chocolate Peanut Butter Baked Oatmeal

• Easy to Make: Simply mix the ingredients, bake, and you’re ready to enjoy a delicious, homemade breakfast.
• Satisfying and Filling: Packed with fiber and healthy fats, this oatmeal will keep you full all morning long.
• Make Ahead: Bake a pan of oatmeal and store it in the fridge, so you have a delicious breakfast (or snack) ready to go for several days.
• Tastes Like Dessert: With the rich combination of chocolate and peanut butter, this baked oatmeal tastes like a decadent treat but is actually made with wholesome ingredients. You can even enjoy a piece for dessert, it’s that good!
• Customizable: Whether you prefer dark chocolate, or want to add fruit or nuts, this oatmeal is easy to customize. If you want extra protein, add a scoop of chocolate protein powder! You can also make it gluten-free by using gluten-free oats and vegan by using flax eggs and plant-based milk.

Key Ingredients

You’ll find the full list of ingredients in the recipe card below, but here are some ingredient notes before you get started.

• Rolled Oats: The base of the recipe, offering fiber, vitamins, and minerals for a nutritious breakfast. If you need the recipe to be gluten-free, use gluten-free oats.
• Peanut Butter: Adds a creamy texture and rich flavor, along with healthy fats and protein. Use natural peanut butter (only peanuts and salt). Stir well before using!
• Mashed Bananas: The bananas add sweetness and keep the oatmeal moist. For best results, use overripe bananas that are very dark brown.
• Unsweetened Cocoa Powder: For a rich chocolatey taste! You can also use Dutch processed cocoa powder also works well for a deeper chocolate flavor. If you want a protein boost, you can also add a scoop of your favorite chocolate protein powder.
• Eggs: Help bind the ingredients together and give the oatmeal a fluffy texture. To make the recipe vegan, use flax eggs. (1 tablespoon ground flaxseed + 3 tablespoons water = 1 egg)
• Milk: Any milk works, whether dairy or plant-based like almond or cashew milk.
• Maple Syrup: Use pure maple syrup to sweeten the oatmeal.
• Chocolate Chips: I like to add chocolate chips to make the oatmeal extra decadent.

How to Make Chocolate Peanut Butter Baked Oatmeal

• Preheat the oven. Preheat your oven to 350°F and grease a 8×8-inch baking dish with cooking spray. Set aside.
• Mix the dry ingredients. In a large mixing bowl, stir together the oats, cocoa powder, baking powder, and salt.

• Whisk together wet ingredients. In a large bowl, whisk together mashed bananas, milk, peanut butter, eggs, maple syrup, and vanilla. Make sure everything is fully combined.

• Combine ingredients. Add the liquid ingredients to the oat mixture and stir until combined. Stir in ¼ cup of the chocolate chips…or however many you want. Measure with your heart:)

• Pour and bake. Pour the oatmeal mixture into the prepared baking dish and spread it out evenly. Bake for 35 minutes, or until the oatmeal is firm in the center and set.

• Cool. Remove from the oven and allow the baked oatmeal to cool for a few minutes before serving.

Serving Suggestions

• Top with Fresh Fruit: Add sliced bananas, strawberries, or raspberries to complement the chocolate and peanut butter flavors.
• Drizzle with Extra Peanut Butter: For an extra indulgent touch, swirl a little more peanut butter on top before serving.
• Flaky Sea Salt: Sprinkle a little flaky sea salt on top to enhance all of the flavores.
• Serve with Greek Yogurt: Add a dollop of Greek yogurt on top for extra creaminess and a protein boost.
• Sprinkle with Nuts or Seeds: Chopped walnuts, almonds, peanuts, or chia seeds will add crunch and additional healthy fats.
• Whipped Cream: Add a dollop of whipped cream for an extra special treat.
• Enjoy with a Beverage: This baked oatmeal pairs wonderfully with coffee, tea, or a glass of milk!

How to Store & Reheat

One of the best things about this recipe is how well it stores, making it perfect for meal prep!

• In the Fridge: Store leftover baked oatmeal in an airtight container in the refrigerator for up to 5 days. Simply reheat individual portions in the microwave or oven before serving.
• In the Freezer: For longer storage, freeze individual portions by wrapping them in plastic wrap or placing them in freezer-safe bags. They’ll keep for up to 2 months. To reheat, microwave from frozen or bake in the oven at 350°F until heated through.
