Ingredients for 3-Ingredient Peanut Butter Banana Mini Muffins

You won't believe how easy these 3-Ingredient Peanut Butter Banana Mini Muffins are to make! With just three everyday ingredients, you can whip up a batch of soft, moist, flourless banana peanut butter muffins in about 20 minutes, plus cooling time. No flour, baking powder, or added sugar is needed in the batter!

Here's a quick look at what you'll need:

• 1 Very Ripe Medium Banana (About ½ Cup Mashed): The riper the banana, the sweeter your muffins will taste! Look for a banana with plenty of brown spots. It adds natural sweetness, moisture, and delicious banana flavor.
• 1 Large Egg: Helps bind the ingredients together and gives these flourless mini muffins structure as they bake.
• ¼ Cup Creamy Peanut Butter: Adds rich peanut butter flavor and helps create a soft, tender texture. Use smooth, well-stirred peanut butter for the best results.

Optional Topping

• Melted Peanut Butter Drizzle: I drizzled a little warm, melted peanut butter over my finished mini muffins for extra peanut butter flavor and a delicious finishing touch!

Kitchen Tools You'll Need

• Mini muffin pan (preferably silicone or well-greased nonstick)
• Medium mixing bowl
• Fork or potato masher
• Whisk or spoon
• Measuring cups
• Wire cooling rack

How to Make 3-Ingredient Peanut Butter Banana Mini Muffins (Step-by-Step)

Making these 3-Ingredient Peanut Butter Banana Mini Muffins couldn't be easier! With just one mixing bowl, three simple ingredients, and about 20 minutes of prep and baking time, you'll have a delicious batch of soft, moist, flourless mini muffins ready to enjoy after cooling.

Follow these easy steps for the best results!

Step 1: Preheat the Oven and Prepare Your Muffin Pan

Preheat your oven to 350°F (175°C). Lightly grease 12 wells of a mini muffin pan with nonstick cooking spray. A silicone mini muffin pan works especially well because these flourless muffins are delicate and can stick to traditional muffin pans.

Step 2: Mash the Ripe Banana

Peel one very ripe medium banana and place it in a medium mixing bowl. Using a fork or potato masher, mash the banana until it's nearly smooth.

You should have approximately ½ cup of mashed banana. A banana with plenty of brown spots provides natural sweetness and moisture, making these peanut butter banana muffins extra delicious!

Step 3: Add the Egg

Crack one large egg into the bowl with the mashed banana. Whisk until the egg is completely incorporated and the mixture looks smooth and well combined.

The egg helps bind these flourless banana muffins together and gives them structure as they bake.

Step 4: Mix in the Peanut Butter

Add ¼ cup of creamy peanut butter to the banana and egg mixture. Stir thoroughly until you have a smooth, uniform muffin batter with no large peanut butter lumps.

If you're using natural peanut butter, make sure it's well stirred before measuring.

Step 5: Fill the Mini Muffin Pan

Using a small spoon or cookie scoop, divide the batter evenly among 12 prepared mini muffin wells, filling each approximately ¾ full.

Because these are flourless mini muffins without baking powder, they won't rise as much as traditional bakery-style muffins.

Step 6: Bake Until Set

Place the muffin pan in your preheated oven and bake for 12-15 minutes, or until the centers appear set and a toothpick inserted into the middle comes out without wet batter.

Start checking at 12 minutes to avoid overbaking. These easy peanut butter banana muffins should remain soft and moist.

Step 7: Cool Before Removing

Remove the muffin pan from the oven and allow the muffins to cool in the pan for at least 5 minutes. For easier removal, let them cool longer until they've firmed up.

Carefully loosen the edges if needed, then transfer the muffins to a wire rack to finish cooling.

Important Baking Tip: Because these mini muffins contain no flour, they're more delicate than traditional muffins. Allowing them to cool thoroughly helps prevent them from breaking or sticking to the pan.

Step 8: Add a Peanut Butter Drizzle (Optional)

For an extra-delicious finishing touch, warm a small amount of creamy peanut butter in the microwave for a few seconds until it's smooth and easy to drizzle.

Using a spoon, drizzle the melted peanut butter over your cooled mini muffins.

This optional topping adds even more rich peanut butter flavor and makes these 3-ingredient flourless banana muffins look absolutely irresistible!

Step 9: Serve and Enjoy!

Your homemade Peanut Butter Banana Mini Muffins are ready to enjoy!

These bite-sized treats are perfect for breakfast, afternoon snacking, or a simple homemade dessert.

And trust me, they may disappear quickly! My husband loved these little muffins so much that he ate all 12 from my first batch!

Quick Reminder: These flourless mini muffins have a naturally soft, moist, slightly dense texture rather than the fluffy texture of traditional muffins. That's part of what makes this easy 3-ingredient recipe unique!

Expert Tips for Perfect 3-Ingredient Peanut Butter Banana Mini Muffins

These 3-Ingredient Peanut Butter Banana Mini Muffins are incredibly easy to make, but after testing this recipe in my own kitchen, I discovered a few helpful tricks that will make your baking experience even better!

Here are my best tips for making soft, delicious flourless peanut butter banana mini muffins every time.

• This is my #1 tip! Even though I sprayed my mini muffin pan with nonstick cooking spray, a few of my muffins still stuck to the bottom.
• Because these muffins are made without flour, they're naturally soft and delicate, which can make removing them from the pan a little tricky.
• My recommendation: Try using mini muffin paper liners or a silicone mini muffin pan for easier removal. If you're using a traditional metal muffin pan, grease the bottoms and sides thoroughly.
• And don't rush to remove them! Allow the muffins to cool and firm up before gently lifting them out of the pan.
• 2. Double the Recipe - Trust Me, You'll Want More!
• Here's something I learned the hard way: 12 mini muffins might not be enough! 😂
• This easy peanut butter banana muffin recipe makes just 12 bite-sized muffins, and they disappeared so quickly in my house that my husband actually ate the entire batch!
• If you're making these for your family, meal prepping, or just love having a sweet little snack ready to grab, I highly recommend doubling the recipe.
• To make 24 mini muffins, you'll need:
• 2 very ripe medium bananas (approximately 1 cup mashed)
• 2 large eggs
• ½ cup creamy peanut butter
• Simply follow the same instructions and bake at 350°F for approximately 12-15 minutes, checking that the centers are set. Bake in batches if necessary.
• 3. The Riper the Banana, the Better!
• For the sweetest and most flavorful banana mini muffins, use a very ripe banana with plenty of brown spots.
• Since this recipe doesn't require added sugar in the batter, the banana provides most of the natural sweetness.
• 4. Measure Your Mashed Banana
• One medium banana should give you approximately ½ cup of mashed banana.
• Using too much banana can make these flourless mini muffins overly wet, so measuring your mashed banana is a helpful way to get consistent results.
• 5. Stir Your Peanut Butter Before Measuring
• Creamy peanut butter works best for this recipe. If you're using natural peanut butter, stir it thoroughly so the oils are evenly incorporated before adding it to your batter.
• This helps everything mix together smoothly.
• 6. Don't Overbake Your Mini Muffins
• These 3-ingredient banana peanut butter muffins bake quickly!
• Start checking them at around 12 minutes. They're ready when the centers are set and a toothpick inserted into the middle comes out without wet batter.
• Overbaking can make these little muffins dry instead of soft and moist.
• 7. Don't Skip the Peanut Butter Drizzle!
• Okay, this one is optional, but it's my favorite finishing touch!
• Warm a small spoonful of creamy peanut butter until it's smooth and pourable, then drizzle it over your cooled mini muffins.
• It adds extra peanut butter flavor and makes these simple little muffins look absolutely irresistible!
• My Final Baking Tip: If I could give you just two pieces of advice, they would be to use a silicone mini muffin pan or paper liners to prevent sticking, and make a double batch! These little peanut butter banana muffins are simply too good to make only 12!
