These Banana Blackberry Muffins are soft, fruity, and topped with cinnamon streusel and a vanilla glaze. A cozy twist on classic banana muffins with just the right pop of berry sweetness.
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.
