Best Banana Chocolate Chip Muffins

These Banana Chocolate Chip Muffins are incredibly moist, tall, and loaded with chocolate in every bite. The high-heat start creates the bakery dome top, and sour cream keeps them soft for days.

Ingredients
  

  • 3 very ripe Bananas, mashed About 1½ cups or 340g. The riper and spottier the better.
  • 2 cups All-purpose flour 240g, spooned and leveled or weighed
  • 1 tsp Baking powder
  • ½ tsp Baking soda
  • ½ tsp Fine sea salt
  • 1 tsp Ground cinnamon
  • ½ cup Light brown sugar, packed 100g
  • ¼ cup Granulated white sugar 50g
  • ¼ cup Unsalted butter, melted 55g, slightly cooled
  • ¼ cup Neutral oil 60ml, vegetable or canola
  • 2 large Eggs Room temperature
  • ½ cup Full-fat sour cream or Greek yogurt 120g
  • 2 tsp Pure vanilla extract
  • 1½ cups Semisweet chocolate chips 255g, divided. Save a handful for topping.
  • 1 tsp All-purpose flour For tossing with chocolate chips to prevent sinking
  • ½ tsp Turbinado sugar per muffin Optional, for crunchy top

Equipment

  • 1 12-cup muffin tin Standard size
  • 12 Paper muffin liners Essential for clean release and shape
  • 2 Mixing bowls One large for wet, one for dry ingredients
  • 1 Rubber spatula For gentle folding only, never a whisk for combining
  • 1 Cookie scoop For evenly portioned muffins
  • 1 Kitchen scale Recommended for accurate flour measurement
  • 1 Wire Cooling Rack For cooling after pan rest

Method
 

Prep
  1. Line the Tin and Start Hot: Preheat the oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners. Starting at 425°F is what creates the tall domed top. Do not skip this or start at 350°F from the beginning.

Mash the Bananas
  1. Fork Only, Not a Blender: Peel the very ripe bananas into a large mixing bowl and mash thoroughly with a fork until almost completely smooth. A few small lumps are fine. Over-processing in a blender produces a thinner, wetter batter that rises less reliably.

Mix the Wet Ingredients
  1. Combine Everything Into the Bananas: Add both sugars to the mashed bananas and stir to combine. Add the melted butter, oil, room temperature eggs, sour cream, and vanilla extract. Stir until the mixture looks smooth and uniform. Room temperature eggs are important here since cold eggs can cause the melted butter to solidify into lumps.

Combine the Dry Ingredients
  1. Whisk Separately First: In a separate bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon until evenly combined. Whisking the dry ingredients together first ensures even distribution of the leavening before it contacts the wet batter.

Fold Together, Stop Early
  1. This Step Makes or Breaks the Texture: Pour the wet banana mixture into the bowl with the dry ingredients. Using a rubber spatula, fold together with slow, gentle strokes from the bottom of the bowl upward. Stop after 10 to 12 folds when you can still see a few flour streaks. The batter will look rough and lumpy. This is correct. Overmixing builds gluten that produces a dense, rubbery, tunnel-filled muffin.

Add the Chocolate Chips
  1. Toss in Flour First: Toss the chocolate chips with one teaspoon of flour in a small bowl to coat lightly. Fold the flour-coated chips into the batter with 4 to 5 gentle folds. Let the batter rest for 5 minutes while the flour absorbs the moisture from the bananas.

Fill and Top
  1. Fill All the Way to the Top: Use a cookie scoop or large spoon to fill each muffin liner to the very top. Overfilling is correct for tall domed muffins. Press a few reserved chocolate chips on top of each filled cup. Sprinkle turbinado sugar over each one if using.

Bake High Then Low
  1. Do Not Open the Oven Between Steps: Bake at 425°F for exactly 5 minutes. Without opening the oven door, reduce the temperature to 350°F (175°C) and bake for a further 15 to 18 minutes until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.

Cool and Serve
  1. Rest 10 Minutes in the Pan: Let the muffins cool in the tin for 10 minutes before transferring to a wire rack. The structure sets during this rest. These banana chocolate chip muffins are best eaten warm or at room temperature on the day of baking, but stay moist for up to 3 days in an airtight container at room temperature.

Notes

  • Very ripe bananas only. Brown-spotted or mostly brown bananas have the most sugar, flavor, and moisture. Yellow bananas produce a muted, starchy flavor.
  • Measure flour correctly. Scoop flour gently into the measuring cup with a spoon and level off, or weigh at 240g. Scooping directly from the bag compacts the flour and adds 20 to 40 percent too much.
  • 425°F start is non-negotiable for dome tops. This high-heat blast causes rapid rise before the crust sets. Without it, the tops bake flat.
  • Stop mixing at 10 to 12 folds. The batter should still look lumpy. Overmixing is the number one cause of dense, gummy muffins.
  • Flour the chocolate chips before folding in to prevent sinking to the bottom during baking.
  • Sour cream keeps muffins moist. Full-fat sour cream or full-fat Greek yogurt both work equally well. Do not use low-fat versions.
  • Do not open the oven between the 425°F start and the 350°F reduction. The temperature drop from opening the door interrupts the rise.
  • Storage: Airtight container at room temperature up to 3 days. Do not refrigerate. Freeze individually wrapped up to 3 months.
  • Quick banana ripening: Bake unpeeled bananas at 300°F for 20 to 30 minutes until skins turn black. Cool completely before using.
  • UK/Australia notes: "All-purpose flour" equals plain flour. "Baking soda" equals bicarbonate of soda. "Sour cream" is available globally under the same name.
  • Nutrition values are estimates and vary based on banana size, exact sugar quantities, and chocolate chip amount.
