Equipment

  • Kitchen scale with a paddle attachment (please weigh your ingredients for best results)
  • Stand mixer (or large bowl with a whisk)
  • 12-muffin pan
  • Parchment Paper
  • A medium bowl for mixing dry ingredients
  • Small bowl for mixing the streusel

Ingredients
  

For the blackberry banana muffins

  • 2 ½ cups all-purpose flour 300g
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground cardamom optional
  • 3-4 ripe bananas mashed about 1.5 cups
  • 6 tablespoons melted butter unsalted
  • 2 teaspoons vanilla
  • 1 egg
  • 2-4 tablespoons milk**
  • cup packed brown sugar light or dark, 147g
  • 1 cup blackberries fresh or frozen (I used frozen)

For the cinnamon streussel

  • ½ cup all-purpose flour 60g
  • ½ cup cane sugar 100g
  • 4 tablespoons unsalted butter melted
  • pinch salt
  • ½ teaspoon ground cinnamon optional

For the vanilla glaze

  • 1 cup powdered sugar 120g
  • ½ teaspoon vanilla extract
  • 2 tablespoons milk

Instructions
 

  • Preheat your oven to 425°F and prepare a muffin pan with cupcake liners*.
  • In a small bowl, mix together the dry ingredients.
    2 ½ cups all-purpose flour, 2 teaspoons baking powder, 1 teaspoon baking soda, ½ teaspoon salt, 1 teaspoon ground cinnamon, ¼ teaspoon ground cardamom
  • In a medium bowl, mash bananas thoroughly and add in the wet ingredients.
    3-4 ripe bananas mashed, 6 tablespoons melted butter, 2 teaspoons vanilla, 1 egg, ⅔ cup packed brown sugar
  • Add dry ingredients to the wet ingredients and mix until fully incorporated. Be careful not to over-mix because over-mixing will impact the rise of the muffin. Add the milk last, 1 tablespoon at a time, until the batter looks like the picture in the "Instructions" section. This batter is thick (see instructions section for photo example)
    2-4 tablespoons milk**
  • In a small bowl, toss the fresh or frozen blackberries in 1-2 tablespoons of flour until coated and gently stir the berries into the batter. Evenly divide the batter on a prepared 12-muffin baking sheet. I use a three-tablespoon cookie scoop to evenly distribute the batter. Each liner will be just over ¾ full.
    1 cup blackberries
  • Mix streusel topping ingredients and generously top each muffin. Use all of it! Even if it seems like too much. Just trust me.
    ½ cup all-purpose flour, ½ cup cane sugar, 4 tablespoons unsalted butter, pinch salt, ½ teaspoon ground cinnamon
  • Bake for 5 mins at 425°F and then switch to 350°F for another 15-16 minutes or until you can stick a toothpick in it and it comes out with just a few crumbs. Don’t open the oven when you change the temp!
  • Allow the muffins to cool completely before mixing your glaze in a small bowl (like a cereal bowl) with a fork or whisk. You want the glaze to be nice and thick, so add 1 tablespoon of milk at a time until you reach your preferred consistency.
    1 cup powdered sugar , ½ teaspoon vanilla extract, 2 tablespoons milk, pinch salt
  • Allow the glaze to set before serving for best results and enjoy!

Notes

*To prevent the muffins from baking into each other, I like to use two muffin pans with each muffin baking with enough space to spread evenly.
** depending on the ripeness of the bananas, you might need more or less milk, so add it last, one tablespoon at a time until you reach the desired consistency featured in the images in the instructions section.
