Prep & Cook Time

Prep Time: 10 minutes

Cook Time: 18 minutes

Total Time: 28 minutes

Servings: 12 muffins

Ingredients

  • 1½ cups all-purpose flour ((180g))
  • 1½ cups old fashioned rolled oats (plus more for topping (150g))
  • ⅔ cup granulated sugar ((133g))
  • 1½ teaspoons baking powder
  • ½ teaspoon baking soda
  • 1 teaspoon ground cinnamon (plus more for topping)
  • ½ teaspoon salt
  • ⅔ cup milk ((120ml))
  • ⅓ cup vegetable oil ((60ml))
  • 2 large eggs
  • 1 teaspoon vanilla powder (use half this amount if you prefer less rich vanilla flavor)
  • 1 cup mashed ripe banana ((about 2 bananas/250g))
  • ½ cup chocolate chips (optional (90g))

Instructions

  1. Preheat your oven to 375°F (190°C). Line a standard 12-cup muffin tin with paper liners or grease the cups well.
  2. In a large mixing bowl, whisk together the all-purpose flour, rolled oats, granulated sugar, baking powder, baking soda, ground cinnamon, and salt.
  3. In a separate medium bowl, combine the milk, vegetable oil, eggs, and vanilla powder (use half this amount if you prefer less rich vanilla flavor). Whisk vigorously until the mixture is smooth and well-emulsified.
  4. Divide the batter evenly among the 12 prepared muffin cups, filling each about ¾ full. Sprinkle the tops with a pinch of extra rolled oats and a light dusting of cinnamon.
  5. Bake for 16-18 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
  6. Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Variations

  • Cinnamon Swirl: Before baking, create a quick swirl by mixing 1 tablespoon of the batter with ½ teaspoon extra cinnamon. Dollop this on top of each muffin and swirl with a toothpick.
  • Mini Muffins: For bite-sized treats, bake in a mini muffin tin for 10-12 minutes. This recipe will yield about 24 mini muffins.
  • Crunchy Streusel Topping: Replace the oat topping with a simple streusel made by rubbing together 2 tablespoons each of flour, oats, and brown sugar with 1 tablespoon softened butter until crumbly.
  • Double Chocolate: If using chocolate chips, try swapping half of them for cocoa powder by replacing 3 tablespoons of the flour with an equal amount of unsweetened cocoa powder.

Tips for Success

  • Use very ripe bananas with plenty of brown spots for maximum sweetness and flavor.
  • To mash bananas quickly, place them in a bowl and use a potato masher or the back of a fork.
  • For taller muffins, let the batter rest for 10 minutes after mixing before portioning into the tin. This allows the oats to absorb some liquid.
  • Avoid overmixing the batter, as this can develop the gluten in the flour and lead to dense, tough muffins.

Storage & Reheating

Store completely cooled muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. To reheat, warm a muffin in the microwave for 15-20 seconds, or wrap it in foil and place it in a 300°F (150°C) oven for 5-10 minutes until warm throughout.

FAQ

Can I use quick oats instead of old fashioned rolled oats?

Yes, quick oats can be used, but the texture will be less distinct and more cake-like. The muffins may also be slightly denser.

Can I make this recipe dairy-free?

Absolutely. You can substitute the milk with any unsweetened non-dairy milk, such as almond, soy, or oat milk.

Why are my muffins dry?

Over-baking is the most common cause. Check them at the 16-minute mark, as oven temperatures can vary. Also, ensure you are measuring your flour correctly by spooning it into the cup and leveling it off.

Can I reduce the sugar?

Yes, you can reduce the sugar to ½ cup for a less sweet muffin, but the texture and browning may be slightly affected.

Can I skip the chocolate chips?

Of course. The muffins are delicious without them, or you can simply omit them for a classic banana oatmeal flavor.

My muffins didn’t rise much. What happened?
