Banana Cake with Streusel Topping

Banana Cake with Streusel Topping
I had three very ripe bananas to use up so my daughter and I decided to make a banana cake with streusel topping. I made the mistake of putting the cake in a small 8×8 pan instead of a 9×13 pan so the cake took an hour to bake. Next time I make this, and there will be a next time because my kids LOVED it, I will use the larger pan. It turned out very moist and flavorful – perfect for breakfast, snack, or dessert. Both of my kids gave this cake a double thumbs up.

Place in the oven and bake for 30 minutes or until a tester inserted in the center comes out clean. Let the cake cool for 10 minutes before slicing. Enjoy.

Side Note: If you use an 8×8 pan, you will need to bake for closer to 50-60 minutes.

  1. I finally started taking the bananas since nobody else would, and now i have wonderful banana recipes from your blog. I can't wait to try this cake

  2. This cake totally overflowed in my 9 by 13 pan. Suggest you use two round cake pans or a 15″ bar pan. Too much batter! Smelled delicious, but made a huge mess.
