Chocolate Banana Streusel Muffins

September 10, 2015

Test Kitchen-Approved

Author Notes: Light, delicate banana muffins with a sweet, crumbly chocolate streusel topping. A note! There is no baking powder here because of the brown sugar (you don't need it because of the acid from the molasses in brown sugar). If you swap in regular sugar for the brown sugar, be sure to add 1 teaspoon baking powder. Posie (Harwood) Brien

Makes: 9 medium muffins (or 6 large)


For the muffins:

  • 1/3 cup butter, softened
  • 1/3 cup firmly packed brown sugar
  • 1 egg
  • 1/2 teaspoon vanilla extract
  • 1 cup mashed banana (about 2 medium bananas)
  • 1 cup flour
  • 1/2 teaspoon salt
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground ginger (optional)

For the streusel:

  • 1/2 cup flour
  • 1/2 cup firmly packed brown sugar
  • 1/4 cup butter, softened
  • 1/2 cup semisweet chocolate chips (chopped roughly)
In This Recipe


  1. Preheat the oven to 350° F. Line a muffin pan with paper liners. You can make 6 large muffins (I like to fill my cups more than halfway) or 9 medium ones (and only fill them halfway).
  2. In a large bowl, cream the butter and sugar. Add the egg, vanilla, and banana and mix well to combine.
  3. In a separate bowl, whisk together the flour, salt, cinnamon, baking soda, and ginger (if using). Add the dry ingredients to the wet and mix just until combined.
  4. Pour the batter into the prepared muffin tins.
  5. In a small bowl, combine all the streusel ingredients except for the chocolate. Mix with a fork or your fingers until combined. Add the chocolate and mix well. Crumble the streusel topping over the muffins.
  6. Bake for 18 to 25 minutes. The tops should feel just set and the edges of the muffin should be starting to turn golden brown. Remove from the oven and let cool in the pan until cool enough to remove.

These were delicious! Thank you! Added cardamom and made with half whole wheat flour. Also subtracted the chocolate from the topping with my cardamom addition. Tasty!

Made these on the weekend, doubled the recipe and they turned out great. I had them in the oven a bit longer than I should of so the brown sugar in the struesel caramelised and became crispy which is perfect in contrast to the lightness of the muffins.

These muffins are SO good! Moist, light banana flavor, chocolate chips- perfect! I doubled the recipe, then couldn't stop eating them, so I took them to a church event where they were snatched up. Making more for playgroup tomorrow. My new go-to banana muffins. Thanks Posie!
