These banana protein muffins are the ultimate grab and go breakfast or snack for busy mornings. Packed with sweet ripe banana and melty chocolate chips they feel like a treat but sneak in wholesome ingredients. I love keeping a batch on hand so my family always has something homemade and satisfying to enjoy with coffee or after a workout.
I first got hooked on these muffins when I needed a quick energy boost before morning runs. Now they are a regular request for both breakfast and lunchboxes because everyone loves the gooey chocolate chips.
Ingredients
- Ripe bananas: give natural sweetness and classic flavor so look for ones with lots of brown spots as they mash easily and taste best
- Eggs: provide structure and bind the muffins for a sturdy yet tender crumb choose fresh large eggs for best results
- White sugar: brings just enough sweetness and helps the muffins brown feel free to swap in coconut sugar or maple syrup if you like
- Sour cream: adds moisture and a bit of tang making every bite tender check the date for freshness before using
- Oat flour: makes these naturally gluten free while adding fiber quickly blend your rolled oats in a blender until super fine for best texture
- Baking powder: lifts the muffins and makes them light double check it is fresh for a reliable rise
- Vanilla protein powder: boosts protein content while giving a subtle flavor choose a brand you love for baking
- Baking soda: reacts with the sour cream and bananas for extra lift make sure yours is fresh to avoid flat muffins
- Salt: balances sweetness and brings flavors together a fine sea salt works well here
- Semi sweet chocolate chips: melt into the batter for pockets of indulgence use a good quality brand for best results and save a few for the tops
Step-by-Step Instructions
- Prep the Oven and Muffin Tin:
- Preheat your oven to 350 degrees F and line a muffin tin with papers or lightly grease each cup to prevent sticking
- Mash the Bananas and Combine Wet Ingredients:
- In a large bowl mash the bananas until mostly smooth leaving a few chunks for texture then whisk in the eggs sugar and sour cream until just combined and creamy
- Mix Dry Ingredients:
- Add the oat flour baking powder vanilla protein powder if you are using baking soda and salt directly to the bowl stir gently to make a thick and even batter making sure not to overmix which keeps the muffins tender
- Add Chocolate Chips:
- Fold in the chocolate chips using a spatula to distribute them evenly through the batter reserve a handful for sprinkling on top before baking for the best appearance
- Portion the Batter:
- Scoop the batter into your muffin tin filling each cup about three quarters full if you like top each one with a few extra chocolate chips
- Bake and Cool:
- For standard muffins bake for 18 to 20 minutes checking with a toothpick for doneness if making mini muffins bake for about 10 minutes once done let the muffins cool in the tin for 10 minutes then gently transfer them to a wire rack to cool completely before eating

The oat flour is my favorite ingredient because it gives the muffins a tender crumb plus extra nutrients and a wonderful hearty flavor. Last summer we brought a picnic basket full of these for a hike and they disappeared before we even reached the first overlook.
