  • 1 ½ cups old fashioned (rolled) oats
  • 1 ¼ cups all-purpose flour
  • ½ cup granulated sugar
  • 1 ½ teaspoons baking powder
  • 1 teaspoon baking soda
  • ¼ teaspoon salt
  • 1 teaspoon ground cinnamon
  • Pinch of ground nutmeg
  • 1 large egg
  • ¼ cup neutral oil (vegetable, canola, or melted coconut oil works great)
  • 1 teaspoon vanilla extract
  • 1 ½ cups ripe bananas, mashed (about 3–4 medium bananas)
  • ½ cup old fashioned (rolled) oats (topping)
  • ¼ teaspoon ground cinnamon (topping)
  • 2 tablespoons brown sugar (topping)
  • 2 tablespoons melted butter (topping)

Easy One-Bowl Method

  1. Preheat oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or spray with nonstick spray.
  2. In a large bowl, whisk together oats, flour, sugar, baking powder, baking soda, cinnamon, nutmeg, and salt until evenly mixed.
  3. In a separate bowl, whisk the egg, oil, and vanilla until smooth and combined.
  4. Pour the wet ingredients into the dry ingredients and mix gently just until everything comes together; do not overmix.
  5. Fold in the mashed ripe bananas until the batter is uniform.
  6. If using whole oats, let the batter rest for 5–10 minutes to soften the oats.
  7. Divide the batter evenly into the muffin cups, filling each about three-quarters full.

  9. Sprinkle the topping evenly over each muffin.
  10. Bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  11. Let the muffins cool in the pan for about 5 minutes, then transfer to a wire rack to cool completely.

Pro Tips for Perfect Muffins

  • Pick ripe bananas: The browner and softer, the better for flavor and moistness—see how ultra-ripe bananas boost tenderness in our cottage cheese banana bread.
  • Mix gently: Stir until just combined to keep your muffins light and fluffy; for more pointers, check out these tips for baking perfectly soft muffins.
  • Rest the batter: If using whole oats, waiting 5–10 minutes before baking helps soften them for the best texture.
  • Prevent sticking: Use paper liners or a good spray to make muffin removal easy.
  • Cool fully: Let muffins cool completely before storing to avoid moisture buildup inside your container.

Flavor Swaps and Add-Ins

Want to switch things up? Here are some tasty ideas to personalize your banana oatmeal muffins:

  • Chocolate chip banana oatmeal muffins: Toss in ½ cup mini chocolate chips or your favorite chunks.
  • Blueberry banana muffins: Fold in fresh or frozen blueberries for a pop of fruity sweetness.
  • Vegan options: Replace the egg with a flax or chia egg and swap dairy milk for plant-based yogurt or milk.
  • Peanut butter swirl: Drop 1–2 tablespoons of peanut butter into each muffin cup and swirl it through before baking.
  • Nutty crunch: Add chopped walnuts, pecans, or almonds for some delightful texture.
  • Tropical vibes: Mix in shredded coconut and bits of pineapple for a tropical twist that’s fun and flavorful.

Storage, Freezing, and Reheating

  • Room temperature: Keep your banana oatmeal muffins fresh in an airtight container for up to 3 days.
  • Refrigeration: Store in a sealed container and enjoy for up to 5 days.
  • Freezing: Freeze in a single layer on a baking sheet, then transfer to a zip-top bag for up to 3 months. Reheat in the microwave for about 30 seconds or warm in the oven at 300°F for a few minutes.

Answers to Common Questions

Can I swap instant oats for rolled oats?

Yes! Instant oats will work but expect a softer, less chewy texture. Rolled oats give your banana oatmeal muffins more bite and heartiness.

What’s the best egg substitute for this recipe?

Flax eggs or chia eggs are great alternatives. Just mix 1 tablespoon ground flaxseed with 3 tablespoons water for each egg and let it sit for a few minutes to thicken.

Why did my muffins come out dry or dense?

That often happens when you overmix the batter or don’t use enough banana. Also, overbaking can dry them out, so watch your oven closely and check early if it’s running hot. For extra moisture, a little yogurt in the batter can help keep muffins tender—as you’ll see in our Rhubarb Muffins with Yogurt.
