Description

These Banana Chocolate Chunk Muffins are incredibly moist and packed with sweet bananas, crunchy walnuts, and luscious dark chocolate, creating the perfect bakery-style treat! They are absolutely irresistible straight from the oven or as an easy grab-and-go snack any time of day!


Ingredients

  • ½ cup (100 grams) granulated sugar
  • ½ cup (120 ml) vegetable or olive oil
  • 1 large egg, at room temperature
  • 1 teaspoon (5 ml) vanilla extract
  • 2 cups (250 grams) all-purpose flour
  • 1 ½ teaspoons (8 grams) baking powder
  • ½ teaspoon (3 grams) baking soda
  • ½ teaspoon (3 grams) salt
  • ½ cup (120 ml) buttermilk
  • 3 ripe medium bananas, mashed
  • 1 cup (180 grams) dark chocolate chunks or chips
  • 1 cup (100 grams) chopped walnuts
  • extra chocolate chunks and walnuts for topping (optional)

Instructions

  1. Heat oven to 425 degrees Fahrenheit.
  2. Mash the ripe bananas in a small bowl using a fork or a blender. Put them aside for later.
  3. In a large bowl, use a mixer on medium speed to blend the sugar and oil together until they are combined. Add the egg and beat for one minute until the mixture is light and creamy. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk. Blend on low speed with the mixer only until just combined. Do not overmix the batter.
  6. Gently stir in the mashed bananas, chocolate chunks, and walnuts using a spoon or spatula. Scoop the batter into muffin liners placed in a muffin tin, filling each one almost to the very top. If you like, add a few extra chocolate chunks and walnuts on top of each muffin.
  7. Bake the muffins in the preheated oven at 425 degrees Fahrenheit for 5 minutes. Then, reduce the oven temperature to 375 degrees Fahrenheit and continue baking for 12 to 15 more minutes. The muffins are done when the tops have risen and spring back lightly when touched. Be careful not to bake them for too long, as this can make them dry.

Notes

Mixing Tip: Mixing the batter too much can result in tough muffins. Stir in the bananas, chocolate, and nuts gently by hand until they are just distributed.

Oven Variations: Oven temperatures can vary. Always watch your muffins closely during the last few minutes of baking to avoid overbaking.

Temperature Change: It is very important to reduce the oven temperature after the initial 5 minutes of baking at 425F. This high initial heat helps the muffins rise tall, but keeping it high will burn them.
