Some snacks work because they are small. Mini muffins fit in a lunchbox without crushing, they are easy for little hands to hold, and a whole batch comes together in about 25 minutes. Banana is a good place to start because ripe fruit sweetens the batter, so you need less added sugar.

The one thing that surprises most bakers is how fast these finish. Because mini muffin bake time is only about 11 to 14 minutes, a batch can go from golden to dry in the time it takes to unload the dishwasher. This recipe gives you a reliable starting point, plus a few cues so you can judge doneness by eye instead of by the clock.

What You’ll Need

Makes 24 mini muffins

  • 1½ cups (190 g) all-purpose flour
  • ⅓ cup (65 g) packed brown sugar
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • ½ teaspoon ground cinnamon
  • 2 ripe bananas, mashed (about ¾ cup)
  • 1 large egg
  • ⅓ cup (80 ml) neutral oil, such as canola or sunflower
  • ¼ cup (60 ml) milk
  • 1 teaspoon vanilla extract
  • Optional: ½ cup mini chocolate chips or finely chopped walnuts

You will also need a 24-cup mini muffin pan, a small cookie scoop or spoon, and paper liners if you like.

How to Make Them

  1. Heat the oven. Set it to 350°F (175°C) and place a rack in the center. Grease the pan well, including the cavity corners, or add liners.
  2. Mix the dry ingredients. Whisk the flour, brown sugar, baking powder, salt, and cinnamon in a large bowl.
  3. Mix the wet ingredients. In a second bowl, stir together the mashed bananas, egg, oil, milk, and vanilla until smooth.
  4. Combine gently. Pour the wet mixture into the dry and fold just until no flour streaks remain. A few lumps are fine. Overmixing makes muffins tough.
  5. Add extras. Fold in the chocolate chips or nuts if using.
  6. Fill the cups. Spoon in about one heaping tablespoon of batter per cup, so each is roughly two-thirds full. A small scoop keeps them even, and even muffins bake at the same speed.
  7. Bake 11 to 14 minutes. Start checking at 10 minutes. They are done when the tops spring back lightly and a toothpick comes out clean or with a few dry crumbs.
  8. Cool briefly. Let them rest in the pan for about 5 minutes, then move them to a wire rack so the bottoms stay crisp instead of steaming.

Getting the Timing Right

A few things change how quickly minis bake:

  • Pan color. Dark nonstick pans absorb more heat and brown faster, so check a minute or two early. Light metal pans bake more gently.
  • Pan material. Silicone tends to brown less and often takes a little longer, so judge by the toothpick test rather than color.
  • Oven accuracy. Home ovens can run hotter or cooler than the dial says. For a bake this short, a small oven thermometer helps.
  • Add-ins. Chocolate chips and extra fruit add moisture, which can add a minute.

Tips for Lunchboxes and Little Eaters

  • Cool completely before packing. Warm muffins create condensation and turn soggy in a closed container.
  • Keep the add-ins small for toddlers. Skip whole nuts and chunky pieces for young children. Mashed banana alone makes a soft, safe muffin.
  • Swap in whole wheat. Replace up to half of the flour with whole wheat flour for a heartier bite. The muffins will be a little denser.
  • Cut the sugar further. If your bananas are very ripe, you can reduce the brown sugar to ¼ cup.

Storing and Freezing

Store cooled muffins in an airtight container at room temperature for up to two days. For longer storage, freeze them in a single layer on a tray, then transfer them to a freezer bag for up to three months. Thaw a few at a time on the counter, or warm them for 10 to 15 seconds in the microwave. Frozen minis packed in the morning will usually be thawed by lunchtime.

A Snack Worth Repeating

Once you have the timing down, this batter works for plenty of variations: blueberries, shredded zucchini, or a pinch of nutmeg and a swirl of peanut butter. The small size makes it easy to test a new flavor without committing to a full tray of muffins nobody wants.
