Delicious Peanut Butter Banana Oatmeal Cups

Here’s my go-to recipe for peanut butter banana oatmeal cups, made with simple pantry ingredients like creamy peanut butter, ripe bananas, and hearty oats. They’re perfect for busy mornings or afternoon snacks.

These oatmeal cups have become a regular in our weekly meal prep routine. I usually make a double batch because they disappear so quickly in our house. Nothing better than having breakfast ready to grab and go, right?

What Kind of Peanut Butter Should I Use?

Natural peanut butter is the way to go for these oatmeal cups – you’ll want the kind that only contains peanuts and maybe a touch of salt. While both smooth and crunchy styles work well, smooth peanut butter tends to mix more easily with the other ingredients. If your natural peanut butter has separated (which is totally normal), just give it a good stir before measuring. Stay away from conventional peanut butter brands that add sugar, oils, or stabilizers, as these can affect both the texture and healthfulness of your oatmeal cups. Just remember to bring your peanut butter to room temperature before mixing – it’ll blend much more easily with the other ingredients this way.

Options for Substitutions

These oatmeal cups are super adaptable and work well with several substitutions:

• Peanut butter: Not a fan of peanut butter or have an allergy? Feel free to use almond butter, cashew butter, or sunflower seed butter instead. Just make sure it’s natural and runny for the right consistency.
• Rolled oats: While rolled oats give the best texture and are recommended, you can use quick oats in a pinch. Just avoid steel-cut oats as they won’t cook properly in this recipe.
• Almond milk: Any milk works here – regular dairy milk, oat milk, soy milk, or coconut milk will all do the job just fine.
• Maple syrup: Honey works as a 1:1 replacement, or try agave nectar. You could even use mashed dates (about 4-5) if you prefer a whole-food sweetener.
• Eggs: For a vegan version, use 2 flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, let sit for 10 minutes).
• Chocolate chips: Feel free to swap these with dried fruit like raisins or cranberries, or skip them altogether. You could also use white chocolate chips or peanut butter chips.
• Walnuts: Any nuts work great here – try pecans, almonds, or even seeds like pumpkin or sunflower seeds for a different crunch.

Watch Out for These Mistakes While Baking

The success of these oatmeal cups heavily depends on using very ripe bananas – those with brown spots will give you the best natural sweetness and proper moisture, while yellow or green bananas will leave your cups bland and dry. A common mistake is not measuring the mashed banana correctly – make sure to pack it into the measuring cup for accurate proportions. When mixing, avoid over-stirring the ingredients as this can make your oatmeal cups dense and tough – instead, fold everything together just until combined. For the best texture, don’t skip the 10-minute rest time before adding the mixture to your muffin tin, as this allows the oats to absorb the liquid ingredients. Also, resist the urge to overbake – they’re done when the edges are lightly golden and the center is just set, as they’ll continue cooking slightly while cooling in the pan.

What to Serve With Oatmeal Cups?

These peanut butter banana oatmeal cups are perfect for breakfast or as a snack, and there are lots of tasty ways to enjoy them! For breakfast, try serving them warm with a dollop of Greek yogurt and a drizzle of honey or maple syrup on top. If you’re having them as an afternoon pick-me-up, they pair really well with a cold glass of milk (regular or plant-based) or your favorite coffee drink. You can also serve them alongside some fresh fruit like sliced strawberries or apple wedges for extra nutrition and natural sweetness.

Storage Instructions

Keep Fresh: These oatmeal cups make great grab-and-go breakfasts! Place them in an airtight container and keep them in the fridge for up to 5 days. I like to make a batch on Sunday for easy breakfasts throughout the week – they’re perfect with my morning coffee.

Freeze: These little guys are fantastic for freezing! Once completely cooled, pop them into a freezer-safe bag or container and they’ll stay good for up to 3 months. I usually separate them with parchment paper to prevent them from sticking together.

Thaw & Enjoy: When you’re ready to eat a frozen oatmeal cup, either let it thaw overnight in the fridge or give it a quick zap in the microwave for 20-30 seconds. They taste just as good as fresh ones, especially if you warm them up slightly before eating!

Ingredients

• 1/4 tsp salt
• 1 cup mashed ripe banana
• 2 tbsp maple syrup
• 2 cups rolled oats (old-fashioned, not instant)
• 1 tsp vanilla extract (I use Nielsen-Massey vanilla)
• 2 eggs
• 1 tsp baking powder
• 1/2 cup natural peanut butter
• 1/3 cup chopped walnuts (optional, adds a nice crunch)
• 1/3 cup chocolate chips (plus 2 tbsp for topping)
• 1 tsp ground cinnamon
• 2/3 cup unsweetened almond milk

Step 1: Prepare the Muffin Pan

Start by preheating your oven to 350 degrees F (175 degrees C).

Take a 12-cup muffin pan and line it with muffin liners.

To prevent the oatmeal cups from sticking, spray the liners with nonstick cooking spray.

Step 2: Mix Wet Ingredients

In a medium bowl, combine the following wet ingredients: mashed banana, peanut butter, eggs, maple syrup, almond milk, and vanilla extract.

Mix until the mixture is smooth and well combined.

Step 3: Add and Combine Dry Ingredients

To the wet mixture, add the dry ingredients: oats, baking powder, cinnamon, and salt.

Stir well to ensure everything is thoroughly combined.

Once the batter is smooth, gently fold in ⅓ cup of chocolate chips.

Step 4: Fill Muffin Liners

Evenly distribute the oatmeal batter among the prepared muffin liners in the pan.

For an extra touch of indulgence, sprinkle additional chocolate chips on top of each batter-filled liner.

Step 5: Bake and Serve

Place the muffin pan in the preheated oven and bake for 20-25 minutes, or until the oatmeal cups are set and slightly golden on top.

Allow them to cool before removing them from the pan.

Drizzle with your favorite nut butter before serving, if desired.
