Simple, wholesome ingredients are the key to these delicious muffins.
  • All-Purpose Flour: Provides the structure for our muffins. Make sure to measure it correctly by spooning it into your measuring cup and leveling it off.
  • Leaveners: A combination of baking powder and baking soda gives these muffins their signature lift and beautiful domed tops.
  • Ripe Bananas: The riper, the better! Bananas with lots of brown spots are sweeter and mash more easily, contributing maximum flavor and moisture.
  • Blueberries: Fresh or frozen blueberries work perfectly here. If using frozen, don’t thaw them first to prevent the batter from turning purple.
  • Sour Cream: This is the secret weapon for an ultra-moist crumb. The acidity also helps to tenderize the gluten, resulting in a softer muffin. Full-fat plain yogurt is a great substitute.
  • Melted Butter: Adds rich flavor and contributes to the tender texture.
  • Sugar & Egg: Granulated sugar provides sweetness, while the egg binds everything together and adds richness.
  • Vanilla & Salt: These are essential flavor enhancers that round out the taste of the muffins.

How to Make Blueberry Banana Muffins (Step-by-Step)

Follow these simple steps for foolproof muffins every single time. It’s as easy as mix, fold, and bake!

1. Prep Your Muffin Tin and Oven

First things first, preheat your oven to 425°F (220°C). This initial high heat helps the muffins rise quickly, creating those beautiful bakery-style domes. Prepare a 12-cup standard muffin tin by lining it with paper liners or greasing it well.

2. Combine Wet Ingredients

In a large mixing bowl, mash the ripe bananas with a fork until they are mostly smooth with a few small lumps remaining. Whisk in the granulated sugar, followed by the melted butter, egg, sour cream, and vanilla extract. Mix until everything is well combined.

3. Mix in Dry Ingredients

Add the all-purpose flour, baking powder, baking soda, and salt directly to the wet ingredients in the bowl. Using a spatula, mix until the dry ingredients are *just* combined. Be careful not to overmix; a few streaks of flour are perfectly fine at this stage.

4. Gently Fold in Blueberries

Gently fold the blueberries into the batter until they are evenly distributed. If you’re worried about them sinking, you can toss them with a tablespoon of flour before adding them to the batter. Again, minimal mixing is key!

5. Fill & Bake

Divide the batter evenly among the 12 prepared muffin cups, filling each one nearly to the top. For a finishing touch, sprinkle a little coarse sugar over the tops. Bake at 425°F for 5 minutes, then, without opening the oven door, reduce the temperature to 350°F (175°C) and continue to bake for another 15-18 minutes. The muffins are done when a toothpick inserted into the center comes out clean or with a few moist crumbs attached.

Pro Tips for Bakery-Style Results

Want to elevate your muffin game? Keep these expert tips in mind.

  • Do Not Overmix: This is the most important rule of muffin making! Overmixing the batter develops gluten, which results in tough, dense, and rubbery muffins instead of light and fluffy ones. Mix only until you no longer see dry flour.
  • Room Temperature Ingredients: Using room temperature egg and sour cream helps the batter come together more smoothly and evenly, resulting in a better texture.
  • High-Temp Start for Domed Tops: The initial blast of high heat at 425°F causes the leavening agents to react quickly, forcing the muffin batter to spring upwards and create those coveted tall, domed tops.
  • Fill Muffin Cups to the Top: Don’t be shy when filling your muffin liners. Filling them almost full ensures a nice, hearty muffin with a substantial top. This recipe is designed to make 12 full-sized muffins.

Recipe Variations & Substitutions

This recipe is a fantastic base for customization. Here are a few ideas to make it your own:

Variation Instructions
Streusel Topping Mix 1/3 cup flour, 1/4 cup brown sugar, 1/2 tsp cinnamon, and 3 tbsp cold cubed butter until crumbly. Sprinkle over muffins before baking. Check out our blueberry streusel muffin recipe for more details.
Add Nuts or Spices Fold in 1/2 cup of chopped walnuts or pecans along with the blueberries. For extra warmth, add 1/2 teaspoon of cinnamon or a pinch of nutmeg to the dry ingredients.
Yogurt Substitution No sour cream? No problem. You can substitute an equal amount of full-fat plain Greek yogurt. Our blueberry yogurt muffins are always a hit!
Whole Wheat Flour For a heartier muffin, replace up to half of the all-purpose flour with whole wheat flour. This is a great trick for making healthier blueberry muffins.

Storage and Freezing Instructions

One of the best things about these muffins is how well they keep. Here’s how to store them for later.

Storing at Room Temperature

Store the completely cooled muffins in an airtight container at room temperature for up to 4 days. To prevent them from getting soggy, you can place a paper towel in the bottom of the container to absorb any excess moisture.

How to Freeze Muffins

These muffins freeze beautifully. Once completely cool, place them in a single layer in a freezer-safe bag or container. They will keep for up to 3 months. To enjoy, you can let them thaw at room temperature or warm them gently in the microwave for about 20-30 seconds.

Frequently Asked Questions

Yes, these muffins are perfect for freezing. Allow them to cool completely, then place them in a freezer-safe bag or container. They can be frozen for up to 3 months. Thaw at room temperature or warm briefly in the microwave.

A popular trick is to toss the blueberries in 1 tablespoon of the recipe’s flour before folding them into the batter. The light flour coating can help suspend them in the thicker batter, promoting a more even distribution.
