These Banana Oat Muffins are moist, flavorful, and hearty — perfect for a quick breakfast or on-the-go snack! The batter can be made in less than 10 minutes with wholesome pantry staples for a simple yet utterly delicious pastry.
In a large mixing bowl, combine the flour, oats, baking powder, baking soda, salt, and cinnamon.
Add the mashed bananas, melted butter, sugar, eggs, sour cream, and vanilla. Mix until everything is fully combined.
Scoop into lined or greased muffin tins about ¾ of the way full. Bake for 18–20 minutes or until the tops are golden and set.
Let cool for 10–15 minutes before removing from the tins.
Notes
Use very ripe bananas. The riper the better. That is where all of the sweetness and banana flavor comes from.
Greek yogurt works great as a substitute for sour cream. Make sure it's plain and unsweetened so your muffins don't come out too sweet.
Feel free to fold in chocolate chips or chopped walnuts before scooping!
Be careful not to overmix your batter; it can cause a dense muffin.
I used paper liners for this batch, but you can grease your muffin tin well with butter or coconut oil if you'd prefer to skip the liners.
I like to keep overripe bananas in my freezer to make these muffins and freshly milled banana bread. You can freeze them whole or pre-mash them, then thaw at room temperature before making your batter.
