Last week, I a had bunch of extra bananas ripening on the counter, so I threw them in the freezer, with one thing on my mind….banana bread. Now I know there zillion banana bread recipes out there, (I have several different versions myself), but this one has a special twist because it’s topped with a a fabulous crunchy crumb topping AND browned butter icing!

The key to take any banana bread recipe to the next level, is to use frozen bananas. The next time your bananas get a little past their prime for eating, put them in the freezer to save until you are ready to bake. They will turn black, but don’t worry, they will keep in the freezer for up to 6 months. Freezing them makes them sweeter and creates a banana bread that is LOADED with luscious banana flavor. When thawed, your bananas are also easier to mash. They should be the consistency of banana puree. This particular recipe uses sour cream to make it extra moist and 3 large bananas to LOAD it with banana flavor!

How do you feel about nuts in your banana bread? I have made this recipe both ways…with and without nuts. It depends on who the lucky recipients are. If you do use nuts, I suggest toasting them a bit to give them a richer nut flavor.  To toast them, just put them in a single layer on a sheet pan. Bake them at 375 degrees F. for 5-10 minutes, until they begin to brown. Let them cool, then fold them into the batter.

Now let’s talk about the two things that make this banana bread extra special….crumbs and icing.  If you are in a hurry, you can skip the streusel topping, and just make this as regular banana bread. But it only takes a few minutes to mix up the crumb mixture and it really does create an extraordinary, crunchy top.

The second thing you are going to love about this banana bread is the browned butter icing. Have you browned butter before? Like toasting nuts, it’s another quick little thing that makes a whole lotta difference in the flavor! By using browned butter, your icing has a rich, almost nutty flavor. The directions for browning butter are in the recipe. Just be careful not to brown it too long, as it goes quickly from golden brown to burned. Take it off the heat when it is a shade lighter than you think it should be, then transfer it to a heat safe bowl. You can make extra and store it in an airtight container in the refrigerator for up to a week, just melt it back down before using.

Just look at that crumbly top! Did you know the word streusel is a German word that means “a sprinkling”? There a number of variations of streusels, but basically it is a combination of sugar, flour, cinnamon, butter and possibly nuts. I didn’t use nuts in the topping, but if you are in an “extra nutty” mood, you could add a half cup of chopped nuts to the streusel mixture.streusel banana breadstreusel banana bread

That’s it! Easy Peasy, extra special bread for breakfast or a coffee break. So, plan ahead….put some bananas in the freezer today, and you can bake a loaf of this heavenly bread tomorrow. Your family will thank me! Happy Baking!
