Chocolate Peanut Butter Banana Baked Oatmeal

Chocolate. Peanut butter. Banana. And warm, hearty oats. Can you think of a more comforting combo to start your day?
This Chocolate Peanut Butter Banana Baked Oatmeal is my go-to breakfast when I want something cozy, nutritious, and indulgent without actually being indulgent. It’s naturally sweetened with ripe bananas and just a touch of maple syrup, made with pantry staples, and it's packed with fiber and protein to keep you full for hours.
Perfect for meal prep, brunch gatherings, or just spoiling yourself on a Monday morning, this baked oatmeal is a chocolatey twist on a classic. Best part? It tastes like dessert, but it's breakfast-approved.

Ingredients
  

  • 2 ripe bananas, mashed (the riper the better—think brown spots!)
  • 1/2 cup natural peanut butter creamy or crunchy—your call
  • 1/4 cup maple syrup or honey, agave, or brown sugar
  • 1 large egg or flax egg for vegan
  • 1 3/4 cups unsweetened almond milk or dairy milk, oat milk, etc.
  • 1 tsp vanilla extract
  • 2 1/2 cups old-fashioned rolled oats not quick or steel-cut
  • 1/4 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1/2 tsp cinnamon
  • 1/4 tsp salt
  • 1/3 cup dark chocolate chips or chunks plus more for topping, if desired

Instructions
 

Step 1: Preheat Your Oven

  • Set it to 375°F (190°C). Grab an 8x8 or 9x9-inch baking dish and lightly grease it (or line with parchment paper if you prefer easy cleanup).

Step 2: Mash the Bananas

  • In a large mixing bowl, mash your bananas until mostly smooth. A few lumps are totally fine.

Step 3: Mix Wet Ingredients

  • To the mashed bananas, add:
    Peanut butter
    Maple syrup
    Egg (or flax egg)
    Milk
    Vanilla
  • Whisk everything together until smooth. It should look like a creamy, rich, slightly thick liquid.

Step 4: Add the Dry Ingredients

  • Now stir in:
    - Rolled oats
    - Cocoa powder
    - Baking powder
    - Cinnamon
    - Salt
    Mix until fully combined. Then fold in your chocolate chips (don’t forget to sneak a few).

Step 5: Pour and Bake

  • Pour the batter into your prepared baking dish and spread evenly. Sprinkle extra chocolate chips on top if you're feeling fancy.
  • Bake for 35–38 minutes, until the top is set and a toothpick comes out mostly clean (some melty chocolate is fine!).

Step 6: Cool and Serve

  • Let it cool for at least 10 minutes—it firms up as it sits. Serve warm, at room temp, or chilled straight from the fridge.
