Variations

I love experimenting with this Chocolate Banana Brownie Oatmeal Bake Recipe! It’s so flexible—you can amp it up or tone it down depending on your mood or dietary needs. Here are some of my favorite twists I’ve tried.

  • Add Nuts or Seeds: I sometimes toss in walnuts or pumpkin seeds for crunch; the texture contrast is fantastic.
  • Swap Peanut Butter for Almond or Sunflower Seed Butter: If you’re nut-free or want a milder flavor, this switch works like a charm.
  • Make it Gluten-Free: Use certified gluten-free oats, and it’ll be safe for gluten-sensitive friends.
  • Boost Protein: Stir in a scoop of your favorite plant-based protein powder to fuel your day.
  • Extra Chocolate: Because why not? Feel free to sprinkle more chocolate chips on top before baking for extra melty goodness.

How to Make Chocolate Banana Brownie Oatmeal Bake Recipe

Step 1: Prep Your Pan and Preheat the Oven

Start by preheating your oven to 375°F (190°C). Give your 8×8-inch baking pan a generous spray of non-stick cooking spray or lightly grease it with oil or vegan butter so your oatmeal bake slides out easily later. While the oven warms up, you can get moving on the batter—no rush!

Step 2: Mash Those Bananas Till Smooth

I find that ripe bananas mash best with a fork, turning into a creamy almost pudding-like base. You want about 1 cup of mashed banana, so aim for two very ripe medium ones. This step is key: ripe bananas give natural sweetness and moisture, so skip any that aren’t super ripe or you’ll lose that lusciousness.

Step 3: Combine All the Dry Ingredients

Next, add your rolled oats, unsweetened cocoa powder, chia seeds, espresso powder if using, baking powder, and kosher salt on top of your bananas. Gently stir everything together with a rubber spatula until all the oats are coated and the cocoa is evenly distributed. You’ll notice the chia seeds help everything stick just right without clumping.

Step 4: Stir in the Wet Ingredients and Half of the Chocolate

Pour in the almond milk, add the creamy peanut butter, maple syrup, and vanilla extract, then stir everything together until fully combined. The batter will be thick but scoopable—perfect consistency for baking! Fold in half of your chocolate chips or chopped chocolate so the chocolate melts throughout the oatmeal.

Step 5: Bake and Enjoy the Chocolate Banana Brownie Oatmeal Bake Recipe!

Scrape the mixture into your prepared pan and spread evenly. Top with the remaining chocolate so it creates delightful melty pockets during baking. Pop it into the oven for about 30 to 35 minutes until the edges pull away slightly and the oatmeal looks puffed and set. When done, let it cool for 10 minutes to set—even though I’ll admit, waiting is the hardest part!

Pro Tips for Making Chocolate Banana Brownie Oatmeal Bake Recipe

  • Use Riper Bananas: The riper your bananas, the sweeter and more flavorful your bake will be—don’t rush this!
  • Don’t Skip the Espresso Powder: Adding just a teaspoon really deepens the chocolate notes—it’s my secret weapon.
  • Even Spreading Matters: Spread the batter evenly so it cooks uniformly; uneven layers can lead to soggy spots.
  • Wait Before Slicing: Let the bake cool and set to get clean slices—if you cut too soon, it may fall apart.

How to Serve Chocolate Banana Brownie Oatmeal Bake Recipe

Chocolate Banana Brownie Oatmeal Bake Recipe - Serving

Garnishes

I love sprinkling a little flaky sea salt on top right after baking—it brings out the chocolate’s richness and balances the sweetness perfectly. Sometimes, I add sliced fresh bananas or a dollop of coconut yogurt for extra creaminess and a fresh contrast.

Side Dishes

This bake is pretty hearty by itself, but I sometimes serve it alongside a simple mixed berry salad or a scoop of vanilla vegan ice cream for a special breakfast treat. For a brunch party, a plate of fresh fruit or a light green salad balances well.

Creative Ways to Present

For birthdays, I’ve turned this oatmeal bake into mini muffin tins for individual brownies—that surprise factor always wins big smiles. You can also drizzle melted chocolate or peanut butter on top for a beautiful, glossy finish if you’re aiming to impress guests.

Make Ahead and Storage

Storing Leftovers

I usually store any leftover Chocolate Banana Brownie Oatmeal Bake Recipe in an airtight container in the fridge. It keeps beautifully for up to 4 days. Just cover tightly so it doesn’t dry out, and it tastes even better the next day once the flavors settle.

Freezing

If I want to prep in advance, I slice the bake into portions and freeze them individually. Wrapped tightly in plastic wrap and stored in a freezer-safe bag, they keep well for up to 3 months. This way, I can grab a slice for a quick breakfast anytime.

Reheating

I usually reheat slices by popping them in the microwave for about 30 to 45 seconds or reheating gently in a toaster oven. A warm slice tastes just like freshly baked, so don’t worry if you’re enjoying leftovers—it’s just as comforting!

FAQs

  1. Can I use rolled oats if I only have quick oats?

    Quick oats will work in a pinch, but they tend to make the bake a bit softer and less chewy than rolled oats. If you only have quick oats, keep an eye on the baking time as it might be slightly less, and the texture will be a little different.

  2. Is this recipe vegan and gluten-free?

    Yes! All ingredients are vegan-friendly, and if you use certified gluten-free oats, this recipe is also gluten-free. Just double-check that your chocolate chips and other ingredients don’t contain any hidden gluten.

  3. Can I substitute peanut butter with another nut or seed butter?

    Absolutely! Almond butter, cashew butter, or sunflower seed butter are all great options. Each will add its own unique flavor, so pick your favorite or what you have on hand.

  4. How ripe should the bananas be for best results?

    You want your bananas to be very ripe, with lots of brown spots or even mostly brown skin. These are sweeter and softer, which helps give the bake moisture and flavor without adding extra sugar.

  5. Can I make this recipe ahead for breakfast?

    Yes! It’s perfect for making ahead. Bake it the night before, store in the fridge, and reheat for a quick, satisfying breakfast. It saves so much morning hassle when you’re rushing out the door.

Final Thoughts

This Chocolate Banana Brownie Oatmeal Bake Recipe has become my go-to when I want a breakfast that feels like a treat but gives me real energy. I remember the first time I made it, my whole family gathered in the kitchen, excited and impressed by how something so simple could be so rich and satisfying. I promise, once you try it, you’ll be hooked. So next time you want that chocolatey comfort food without the afternoon crash, whip this up and savor every last warm, gooey bite.

Ingredients

Main Ingredients

  • Non-stick cooking spray
  • 2 very ripe medium bananas
  • 2 cups old-fashioned rolled oats
  • 1/4 cup unsweetened cocoa powder
  • 1 tablespoon chia seeds
  • 1 tablespoon espresso powder (optional)
  • 1 teaspoon baking powder
  • 1/2 teaspoon kosher salt
  • 1 1/2 cups unsweetened almond milk
  • 1/4 cup creamy peanut butter
  • 1/4 cup pure maple syrup
  • 2 teaspoons vanilla extract
  • 1/2 cup vegan semi-sweet or bittersweet chocolate chips or 1 (2-ounce) bar vegan chocolate, chopped, divided
  • Flaky sea salt, for serving (optional)


Instructions

  1. Preheat and prepare pan: Preheat your oven to 375°F and coat an 8×8-inch baking pan with non-stick cooking spray to prevent sticking. Set the pan aside.
  2. Mash the bananas: In a large bowl, mash the ripe bananas with a fork until you have about 1 cup of mashed banana, which will add natural sweetness and moisture to the oatmeal.
  3. Add dry ingredients: To the mashed bananas, add the rolled oats, unsweetened cocoa powder, chia seeds, optional espresso powder, baking powder, and kosher salt. Stir well with a rubber spatula to fully combine these dry ingredients.
  4. Incorporate wet ingredients: Pour in the unsweetened almond milk, creamy peanut butter, pure maple syrup, and vanilla extract. Stir the mixture thoroughly to create a uniform batter.
  5. Add chocolate: Fold in half of the vegan chocolate chips or chopped chocolate to infuse the batter with rich chocolate flavor throughout the oatmeal.
  6. Bake the oatmeal: Transfer the batter evenly into the prepared baking pan. Sprinkle the remaining chocolate on top. Bake in the preheated oven for 30 to 35 minutes, until the oatmeal is puffed, set, and the edges begin to pull away from the sides of the pan.
  7. Cool and serve: Remove the baked oatmeal from the oven and let it cool on the counter for 10 minutes. Optionally, sprinkle flaky sea salt on top to enhance the chocolate flavor. Serve warm for a creamy texture or allow to cool further for a firmer, sliceable dish.

Notes

  • For a stronger chocolate flavor, espresso powder is optional but recommended.
  • You can substitute almond milk with any other plant-based milk if preferred.
  • Letting the oatmeal cool completely will make it easier to slice and serve like a traditional baked cake.
  • Store leftovers in an airtight container in the refrigerator for up to 5 days or freeze for up to 2 months.
  • This recipe is naturally vegan and gluten-free if certified gluten-free oats are used.
