Easy Banana Brown Sugar Muffins with Streusel Crumb Topping (Bakery-Style!)

If you love banana bread, you are going to fall in love with these Easy Banana Brown Sugar Muffins.

They’re soft, buttery, and baked in a jumbo bakery-style muffin pan for that tall, fluffy coffee shop look — but made right in your kitchen!

Each muffin is topped with a sweet streusel crumb topping made from butter, brown sugar, cinnamon, and flour, giving every bite that cozy, crumbly texture that melts in your mouth.

The brown sugar in both the batter and the topping adds a warm, caramel-like flavor that pairs perfectly with ripe bananas.

Ingredients

For the Muffins:

• 3 ripe bananas, mashed
• ½ cup unsalted butter, melted and slightly cooled
• ¾ cup brown sugar, packed
• 1 large egg
• 1 teaspoon vanilla extract
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• ½ teaspoon salt
• 1 ½ cups all-purpose flour
• ¼ cup milk (or buttermilk for a richer flavor)

For the Streusel Topping:

• ¼ cup unsalted butter, melted
• ½ cup brown sugar, packed
• ½ teaspoon cinnamon
• ⅔ cup all-purpose flour

Instructions

1. Preheat oven to 375°F and line or grease a jumbo muffin pan (makes about 6 large muffins).
2. In a large bowl, mash the bananas until smooth.
3. Add melted butter, brown sugar, egg, and vanilla. Whisk until well combined.
4. Stir in the baking soda, baking powder, and salt.
5. Gently fold in the flour and milk until just combined — don’t overmix.
6. Divide the batter evenly into the muffin cups, filling each about ¾ full.

Make the Streusel Topping:
7. In a small bowl, mix together the melted butter, brown sugar, cinnamon, and flour until crumbly.
8. Sprinkle a generous amount of streusel over each muffin.

Bake:
9. Bake for 23–26 minutes, or until the tops are golden and a toothpick comes out clean.
10. Let the muffins cool in the pan for 5 minutes before transferring to a wire rack.

Tips

• Use very ripe bananas — they make the muffins extra moist and naturally sweet.
• Don’t skip the crumb topping! It adds the best texture and flavor.
• If baking regular-sized muffins, reduce bake time to about 18–20 minutes.
• Add a handful of chopped pecans or mini chocolate chips to the batter for a fun twist.

Jennie’s Thoughts

These muffins are one of those recipes that make your kitchen smell like happiness. The brown sugar and cinnamon melt together into the most comforting aroma, and the crumb topping adds the perfect little crunch.

I love baking them in my jumbo muffin pan because they come out looking just like bakery muffins — big, golden, and beautiful. I usually make a batch on the weekend so we can enjoy them with coffee throughout the week.

My mom likes to warm hers up with a pat of butter, and honestly, they taste even better the next day.
