Think banana bread met blueberry muffins — the result is these moist, tender Banana Blueberry Muffins. They’re simple, reliable, and a crowd-pleaser.

They’re ideal when you have very ripe bananas on hand. Grab a cup of coffee and enjoy one warm from the oven.

Why You Will Love These Banana Blueberry Muffins:

  • Fluffy and moist: Ripe bananas add natural sweetness and moisture; a bit of melted butter gives a richer flavor and tender crumb with a lightly sugary crunch on top.
  • Berry-packed: These muffins are full of juicy blueberries. Use fresh or frozen — both work well (see notes about frozen berries below).
  • Quick to make: Prep in about 10 minutes, bake around 20 minutes — perfect for a fast breakfast or snack.
  • Delicious crunchy top: A sprinkle of coarse sugar before baking gives a lovely, crunchy muffin top if you like that extra texture.

Muffin Ingredients:

  • Blueberries: Fresh or frozen. If using frozen, don’t thaw to avoid bleeding into the batter.
  • Bananas: Very ripe, spotted bananas mash easily and bring the best flavor.
  • Butter: Unsalted is preferred; if using salted butter, reduce added salt.
  • Egg: One large, at room temperature for best results.
  • Flour: All-purpose flour measured correctly (stir to aerate, spoon into cup, level with a knife). A 1:1 gluten-free flour can be substituted.
  • Brown sugar: Light brown sugar adds depth; dark brown works too. No white sugar is necessary unless you want a sweeter muffin.
  • Leavening: Baking powder and baking soda — make sure they’re fresh for proper rise.
  • Vanilla: Pure vanilla extract gives the best flavor, but imitation works if that’s what you have.
  • Salt: A pinch of sea salt or regular table salt to balance flavors.

  • In a separate bowl, whisk together flour, salt, baking powder and baking soda. If you like, add cinnamon here (about 2 tsp). Fold the dry ingredients into the wet mixture and stir just until no flour streaks remain — avoid overmixing.
  • Fold in the blueberries gently so they don’t burst too much.

  • Bake at 350°F (175°C) for 18–22 minutes or until a toothpick inserted comes out clean. Cool slightly before serving.

Recipe Tips

  • Cinnamon: I usually skip it, but 2 teaspoons added to the dry ingredients works nicely if you prefer a spiced note.
  • Muffin liners: Use good-quality parchment liners that are nonstick to avoid tearing or sticking.
  • Don’t overdo the berries: Too many blueberries can make the muffins soggy. Don’t exceed an extra 1/3 cup beyond the recipe amount.
  • Fresh leavening: Make sure baking powder and baking soda are fresh to get a proper rise.
  • Measure flour correctly: Stir to aerate flour, spoon into the measuring cup, and level with a knife to avoid dry muffins.
