Ingredient Essentials

Let’s chat about what you’ll need to make these adorable little bites come to life. Gathering your ingredients before you start makes the whole process smoother and more fun.

  • Butter: Make sure your unsalted butter is lovely and soft at room temperature. This helps it cream properly with the sugars for a tender crumb. If you forgot to set it out ahead of time, a few simple tricks can help you soften it quickly.
  • Pantry Staples: You will need the usual suspects for baking goodness. This includes granulated sugar, packed light brown sugar, a couple of large eggs, pure vanilla extract, all-purpose flour, baking powder, baking soda, and some salt to balance everything out.
  • Sour Cream: This is a key player for adding moisture and creating that incredibly soft texture we all love in baked goods.
  • Bananas: You will need about three medium-sized ripe bananas. The spottier and browner they are, the better. Super ripe bananas lend so much natural sweetness and moisture to the muffins.
  • Optional Mix-ins: If you are like me and love a little extra something, mini chocolate chips are a fantastic addition.

Crafting Your Mini Banana Muffins

Creating these delightful mini muffins is quite simple. Just follow these steps for perfect results every time.

  1. Prepare the wet and dry mixtures separately. In a spacious mixing bowl, use your electric mixer to beat together the softened butter along with both the granulated and brown sugars until the mixture is light and creamy looking. Next, beat in the eggs one at a time, then the vanilla, followed by the sour cream. Mix just until everything is smoothly combined. In a different bowl, gently whisk together your dry ingredients the flour, baking powder, baking soda, and salt.
  2. Combine the muffin batter ingredients. Slowly add the dry ingredients into the wet ingredients you just prepared. Do this gradually, stirring everything together with a wooden spoon. Be very careful not to mix more than needed, as overmixing can make your muffins tough. Once the dry and wet are just combined with no dry streaks, gently fold in the mashed banana. This is also the time to fold in any extra things you might be adding, like chocolate chips.
  3. Portion the batter into the muffin tin. Get your mini-muffin pan ready by lining it with paper liners. It is a good idea to lightly mist the liners with nonstick spray too. Use a scoop to fill each prepared muffin liner about two-thirds of the way full. If you are using additional mix-ins, you can sprinkle any remaining chips or nuts evenly over the top of the filled muffin cups before they go into the oven.
  4. Bake, cool down, and enjoy. Place the filled pan into your oven which you have preheated to 350°F (175°C). Bake them for about 12 to 15 minutes. They are ready when they look lightly golden brown and a toothpick inserted into the center of a muffin comes out clean. Once baked, move these adorable mini banana bread muffins onto a wire rack to cool down completely before you dig in.

Baking Success Tips and Fun Variations

Achieving the perfect mini muffin is easy with a few simple tricks. Plus, there are fun ways to change them up.

  • Grease those liners. Do not skip lightly spraying the paper liners with cooking spray before adding the batter. This small step makes it so much easier to remove the muffins without them sticking to the paper.
  • Watch the clock. Mini muffins bake much faster than standard-sized ones. Keep a close eye on them while they are in the oven so they do not overbake.
  • Check for doneness correctly. The best way to tell if they are ready is by inserting a toothpick into the center of one muffin. If it comes out clean with no wet batter attached, they are finished baking. A few moist crumbs are okay.
  • Get creative with add-ins. Besides classic chocolate chips, try stirring in other delicious things. A handful of fresh blueberries adds a lovely pop of flavor, or you could use raisins, shredded coconut, or chopped walnuts for texture. For a warm, spiced twist, a sprinkle of ground cinnamon mixed into the batter is wonderful, or you could even add a simple crumble topping before baking.
  • Think about a double batch. These mini muffins disappear fast. I often make a double batch because they are absolutely perfect for quick snacking throughout the week or grabbing for breakfast on the go. The extras freeze beautifully.
  • Swap for something lighter. You can easily make this recipe a little lighter by using plain Greek yogurt instead of sour cream. They stay wonderfully moist this way. Another option is swapping the butter for the same amount of applesauce.

Storing Your Delicious Muffins

Once your mini banana muffins have cooled completely (it is important they are cool before storing), you will want to keep them fresh.

  • Room Temperature Storage: Store your cooled muffins in an airtight container or a zip-top bag at room temperature. They will stay fresh and delicious for up to four days. A little trick I like to use to help prevent them from getting too soft or sticky from moisture is placing a couple of folded paper towels inside the bag with the muffins. The paper towels help absorb any excess moisture.
  • Freezing for Later: These muffins freeze exceptionally well. Once they are completely cooled, place them in a freezer-safe bag or a container that seals tightly. Label the bag with the date. You can store them in the freezer for up to two months. When you are ready for a frozen treat, you can thaw them at room temperature or warm them quickly. I find warming a frozen mini muffin in the microwave for about 10 seconds works perfectly. They taste just like they were freshly baked.

Frequently Asked Questions

Why should I use ripe bananas for this recipe?

Ripe bananas are sweeter and softer than green or yellow ones. They mash easily and provide natural moisture, which makes the muffins taste better and stay moist longer.

Can I make these into regular-sized muffins instead?

Yes, you can. The baking time will need to be adjusted though. Regular-sized muffins will likely take longer to bake, probably around 20 to 25 minutes. Test for doneness with a toothpick.

Is it okay to leave out the chocolate chips?

Absolutely. The chocolate chips are completely optional. The muffins are delicious with or without them.

My muffins stuck to the liners. What happened?

This can happen if the liners were not greased or if the muffins were not fully cooled before trying to remove them. Make sure to lightly spray the paper liners and let the muffins cool completely on a wire rack.

How long do these muffins last?

Stored properly in an airtight container at room temperature, they are best enjoyed within three to four days.

Can I use milk instead of sour cream?

Sour cream adds richness and moisture that milk cannot fully replicate. While you could potentially swap it for Greek yogurt (as mentioned in variations), using milk would significantly change the texture and might make the muffins less moist.

How many mini muffins does this recipe make?

This recipe is designed to yield a generous batch, typically making about 48 mini muffins. They are perfect for sharing or freezing extras.

Description

These Mini Banana Muffins are a delightful small version of classic banana bread! They are wonderfully moist, light, bursting with sweet banana taste, and baked in just minutes!


Ingredients

  • ½ cup (115 grams) unsalted butter, softened
  • 1 cup (205 grams) granulated sugar
  • ⅓ cup (70 grams) light brown sugar, packed
  • 2 large eggs
  • 1 teaspoon (6 ml) vanilla extract
  • 1 cup (230 grams) sour cream
  • 2 ¼ cups (275 grams) all-purpose flour
  • 2 teaspoons (11 grams) baking powder
  • 1 teaspoon (6 grams) baking soda
  • 1 teaspoon (6 grams) table salt or fine sea salt
  • 1 ¼ cups (305 grams) ripe banana, mashed (about 3 medium bananas)
  • Optional 1 cup (175 grams) mini chocolate chips

Instructions

  1. Warm the oven to 350°F (175°C). Place paper liners into two mini muffin pans. Lightly mist the liners with nonstick cooking spray.
  2. In a large bowl, use an electric mixer to combine the softened butter, granulated sugar, and brown sugar until creamy. Mix in the two eggs, the vanilla extract, and the sour cream just until everything is blended.
  3. In a separate large bowl, gently whisk together the all-purpose flour, baking powder, baking soda, and salt. Gradually add the dry ingredients into the wet ingredients. Stir with a wooden spoon only until the batter is just combined. Be careful not to mix too much. Gently fold in the mashed banana and the mini chocolate chips if you are using them.
  4. Fill the prepared muffin liners so they are about two thirds full. If you are adding chocolate chips, scatter any remaining chips evenly over the top of the muffins before baking.
  5. Bake the muffins for 12 to 15 minutes. They are ready when they are lightly golden brown and a toothpick put into the middle comes out clean. Move the baked muffins to a wire rack to cool down.

Notes

  • Variations You can make the recipe lighter by using plain Greek yogurt instead of sour cream. You can also swap apple sauce for the butter, using the same amount.
  • Add-ins Feel free to stir in other items like chopped nuts, ground cinnamon, or shredded coconut.
  • Storing Keep the muffins in a zip-top bag at room temperature for up to four days. To help prevent the muffins from becoming soft, put a few folded paper towels into the bag to soak up moisture.
  • Freezing Place cooled muffins in a freezer bag or a container that seals tightly. Store in the freezer for up to two months. To heat them up again, warm muffins in the microwave for about 10 seconds or until they are warm through.
