Preheat oven to 350 F. Line a muffin tin with cupcake liners. Set aside.
In a large bowl combine all of the crumb topping ingredients. Use a pastry cutter until mixture is crumbly. Set aside.
In a large bowl, cream together butter, brown sugar and white sugar.
Beat in eggs and vanilla extract. Seat aside.
In a medium bowl, whisk or sift flour, baking soda, baking powder, salt, and cinnamon.
Gradually add flour mixture into the wet mixture alternating with the buttermilk.f Stir just until combined. (Be careful not to overdo it.)
Add lemon juice to mashed bananas.
Gently fold bananas into the batter.
Fill muffin pan 3/4 full of batter.
Spoon on enough crumb topping to completely cover the top. (pinch the crumbs together to create larger crumbs if desired. I used a little over 1 T. of topping per muffin.
Bake for 18-20 minutes.
Remove from oven when moist crumbs cling to a toothpick inserted into the center.
Let muffins sit in the pan for about 4 minutes (they will continue to cook)
Place muffins on a cooling rack to finish cooling. Serve warm or room temperature.

sarah on 2025-01-04 (5 stars): THE BEST MUFFINS EVER!!! I have searched and tried tons of different recipes- these were amazing- and the crumb topping was soft & tasty! I added 1c chopped walnuts and went 1/4 lite on the white sugar for the crumb topping. Kids loved them- 11/10 :) Thank you for our new favorite banana muffin recipe!

GinPhil on 2022-01-23 (5 stars): I've replaced my banana bread recipe with this one! I need to tweek the crumb topping because it's too much. I made a loaf instead of the muffins, added walnuts and baked for about 1 1/2 hours. It came out amazing!! Thanks for the recipe! Yum!!!
Koupon Klipper on 2019-12-20 (5 stars): I searched for a non-nutty banana bread recipe for a social function and came across this. I loved the idea of the crumble top (that's one of my favorite things about apple pie!) so I decided to give it a try. I did cut back a little on the sugar in the actual muffin mix, but otherwise followed it precisely. The instructions were clear and helpful and the muffins turned out fabulously! Thank you.
Tiffany M. on 2019-12-09 (5 stars): Just tried these and they turned out amazing! I filled the muffins cups a little too much so I had to cook a little longer and the middle sank a bit but overall they are fabulous! I drizzled some butter rum sauce over a few..hmmm hmmm good! Sure they'll be even better tomorrow. Thanks!!!!
Umm AM on 2019-03-30 (4 stars): I tried this recipe in place of my tried & true banana muffin recipe. I wanted to like this recipe, but it does not work for my higher altitude (4000+). I baked them a dozen at a time. The muffins sunk in the middle and were slightly gooey in the middle. The second dozen also sank, but were done in the middle as I left them in 7-10min longer. The topping melted on both batches forming a hard, crunchy layer on the top, which was not bad. I will have to tweak this recipe by probably adding more baking powder and decreasing the sugar.
