Step by step instructions
Here is how to make and bake these Banana Crumb Muffins. You will need a 12 muffin tin, muffin liners, 3 mixing bowls, a spatula, and an electric handheld mixer.
Step 1 – Prep. Line your muffin tin with 12 liners and set aside. I used tulip liners, which result in a taller muffin and makes 9 muffins total. If you need a recommendation, this is my favourite tin. Mash the bananas and set aside.
Step 2 – Make the streusel. In a medium sized bowl, add all-purpose flour, brown sugar, cinnamon, and softened butter. Using a fork or your hands, mix this until combined. Set aside in the fridge when done.
Step 3 – Mix dry ingredients. In another medium sized bowl, add in flour, cinnamon, cornstarch, baking soda, and salt. Stir to combine and set aside.
Step 4 – Cream the butter and sugar. In a large bowl, add softened butter, brown sugar, and white sugar. Beat on medium speed for 2-3 minutes until it’s light and fluffy. Make sure to scrap the sides of the bowl.
Step 5 - Add in the eggs and vanilla. Add the eggs and vanilla into the bowl and mix on medium speed until well combined. Make sure to scrap the sides of the bowl.
Step 6 - Add in bananas. Add in the mashed bananas and mix on medium speed until well combined, scraping the sides of the bowls when needed.
Step 7 - Add the dry ingredients and the sour cream. Slowly add the dry ingredients in three additions, starting and ending with the dry ingredients. Alternate between adding in the dry ingredients and the sour cream. Mix until just combined between each addition.
Step 8 – Scoop. Evenly divide the batter between 12 liners in regular liners, they should all the way full. If using tulip liners, you will have 9 liners almost full. Using a cookie scooper helps big time to minimize the mess. Sprinkle a generous handful of streusel on top of each muffin.
Step 9 – Bake. Bake the muffins at 375°F for 20-25 minutes in regular liners, and 25-35 minutes in tulip liners. The muffins are ready when a toothpick inserted comes out clean.
These muffins stay fresh covered at room temperature for up to 3 days, and in an airtight container in the refrigerator for up to a week!
Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Make sure all of your wet ingredients are at room temperature. It’s important or else the ingredients won’t work the way we want them too together.
- The type of sour cream you use matters. Make sure it is full fat.
- For the streusel: Make sure the butter is softened. If you make it with melted butter, the streusel will not turn out.
- The riper the bananas the better. They should have lots of black spots on them!
FAQ
Why is there sour cream in these muffins and can I taste it?
You cannot taste it at all. Using sour cream in muffins creates a very fluffy texture that leaves the muffins soft for days. If you don’t have any sour cream on hand, use full fat plain yogurt instead.
How far in advance can I make these muffins?
This banana crumb muffins stays good on your counter for a few days, and in the fridge in an airtight container for a week.
Can I freeze these muffins?
Yes. If you want to meal prep them, bake them, allow for them to come to room temperature, and then place in an airtight ziplock bag. Store in your freezer for up to 1 month. When ready to eat, remove and allow to thaw. 🙂

Nimi says
What can be substituted for eggs in Banana Crumb Cake ..
Please let me know as I'm vegetarian.
Thank you
Ania says
Hi Nimi, I haven't tried any egg substitutes so I can't say for sure. If you have one that works for you, feel free to try it out, but I can't guarantee the results!
Sheila says
How do they get extra high ? Do you have to bake high then drop the temperature. You didn’t mention in the recipe
Ania says
Hi Sheila! I find that baking in tulip liners gives you an extra tall muffin (That's what I used in this recipe), so I recommend using these if you want that. These muffins only bake at 375F.
