Banana Protein Muffins

Why I Started Making Banana Protein Muffins

I like having something higher in protein on gym days, and for a while I was making shakes with oats, banana, and protein powder. I eventually got tired of drinking the same thing, so I took those ingredients and turned them into muffins instead.

Blending the oats first gives the muffins a smoother, more traditional crumb, while the ripe bananas add the moisture and sweetness that protein powder can otherwise take away. That combination keeps them soft instead of dry or rubbery, which is the biggest issue I’ve run into with a lot of high-protein baked goods.

I love eating a few of these for a quick protein packed breakfast or snack. When I want them for a healthier dessert, I'll add the optional maple cream cheese topping to make them taste like a treat.

Ingredients

For the muffins:

• 1 cup rolled oats
• 2 scoops vanilla protein powder
• 2 eggs
• ½ cup milk
• 2 large ripe bananas
• 1 teaspoon vanilla extract
• ½ teaspoon cinnamon
• ¼ teaspoon baking powder
• ¼ teaspoon baking soda
• Small pinch of salt
• ¼ cup mini chocolate chips

For the optional maple cream cheese topping:

• ½ cup low-fat cream cheese, softened
• 2 tablespoons maple syrup
• 1 teaspoon vanilla extract

Ingredient Notes

How to Make Protein Banana Muffins

Step 1: Blend the oats

Preheat the oven to 350°F and lightly grease a 12-cup muffin pan. Add the rolled oats to a blender and blend until they reach a fine, flour-like consistency.

Step 2: Make the batter

Add the protein powder, cinnamon, baking powder, baking soda, salt, and bananas. Blend briefly, then stop and scrape the sides and bottom of the blender so all of the oat flour gets incorporated.

Add the eggs and vanilla, then blend on medium speed while slowly pouring in the milk. Continue just until the batter is smooth.

Step 3: Fill the muffin pan

Divide the batter evenly between the 12 muffin cups, filling each about halfway. Sprinkle the mini chocolate chips over the tops.

Step 4: Bake

Bake for 10-12 minutes, until the tops spring back when lightly pressed and a toothpick inserted into the center comes out clean or with a few moist crumbs. Let the muffins cool for a few minutes in the pan, then transfer them to a wire rack to cool completely.

Step 5: Make the optional maple cream cheese topping

If you want the topping, beat the softened cream cheese until smooth. Add the maple syrup and vanilla and mix again until creamy and fully combined.

Step 6: Frost and serve

Once the muffins are completely cool, add a dollop of the maple cream cheese topping to each one if you're using it. Serve right away or refrigerate frosted muffins until ready to eat.

Expert Tips for the Best Banana Protein Muffins

• Measure the protein powder by weight. Use 66 grams rather than relying only on two scoops. Scoop sizes vary by brand, and too much protein powder can make the muffins dry or rubbery.
• Pay attention to the batter consistency. Protein powders absorb liquid differently. The batter should be thick but still pourable. If yours is unusually thick after blending, add milk 1 tablespoon at a time until it loosens slightly.
• Don’t keep blending once the batter is smooth. Blend only until everything is incorporated. Running the blender longer than necessary can make the batter warmer and thicker, especially with oats and protein powder.
• Use a cookie scoop for even muffins. Dividing the batter evenly between all 12 cups helps them bake at the same rate and also keeps the protein and calories per muffin more consistent.
• Test one batch early with a new protein powder. Different formulas can change both texture and baking time. Start checking around 10 minutes, especially the first time you make these with a different brand.
• Take them out before they look completely dry. The muffins will continue to set slightly as they cool. Pull them once the centers are set and a toothpick has a few moist crumbs rather than waiting until the tops look dry.
• Add the chocolate chips mostly on top. Since this batter is blended, sprinkling the mini chips over the muffins after portioning keeps them visible and gives you chocolate in each muffin without needing to run them through the blender.

Banana Protein Muffin Variations

• Chocolate banana: Swap the vanilla protein powder for chocolate protein powder for a chocolate-banana version. Keep the mini chocolate chips for an even richer flavor.
• Add nuts: Fold in or sprinkle chopped walnuts or pecans over the tops before baking. Both work especially well with banana and add some crunch.
• Make them dairy-free: Use a plant-based protein powder, use your favorite dairy-free milk, and skip the cream cheese topping or use a dairy-free cream cheese alternative. 

How to Store Protein Banana Muffins

At room temperature: Store unfrosted muffins in an airtight container at room temperature for up to 2 days. Let them cool completely before covering so excess moisture doesn’t make the tops sticky.

In the refrigerator: If you add the maple cream cheese topping, refrigerate the muffins in an airtight container for up to 4 days. For the best texture, you can also store the topping separately and add it just before eating.

To freeze: Freeze the unfrosted muffins in a single layer until solid, then transfer them to a freezer-safe bag or container for up to 2 months. Thaw overnight in the refrigerator or at room temperature, then add the maple cream cheese topping before serving.

Banana Protein Muffins FAQs

How much protein is in each banana muffin?

Each muffin has about 7 grams of protein based on a batch of 12 muffins. The exact amount can vary slightly depending on the type of milk and protein powder you use. Use Fairlife milk for the highest protein muffins.

What kind of protein powder works best for banana muffins?

Vanilla protein powder works especially well because it complements the banana and cinnamon without overpowering them. Whey-based powders generally produce a softer texture, while plant-based or casein-heavy powders may absorb more liquid and make the batter thicker.

Can I use quick oats instead of rolled oats?

Yes. Quick oats can be blended into oat flour and used in this recipe. Avoid steel-cut oats since they won’t blend into the same fine, flour-like texture as rolled or quick oats.

Can I make protein muffins without a blender?

Yes, if you already have oat flour. Substitute the blended oats with an equivalent amount of oat flour, then mix the batter in a bowl until smooth. A blender is simply the easiest way to turn the rolled oats into flour and combine everything at once.

Why are my protein muffins dry or rubbery?

Overbaking is one of the most common reasons protein muffins turn dry or rubbery. Protein powder absorbs moisture quickly, so start checking these muffins around the 10-minute mark and remove them once the centers are set and the tops spring back lightly.

Are banana protein muffins gluten-free?

They easily can be. If you need the muffins to be strictly gluten-free, use certified gluten-free rolled oats and confirm that your protein powder and other ingredients are gluten-free as well.
