Banana Jumbos are an old-fashioned recipe that tastes like banana bread but in cookie form. These treats are moist and so easy to make. Banana Jumbos are the perfect way to use browning bananas to make a handy breakfast or snack.

Old Fashioned Banana Jumbos
This is another treasured recipe from our family archives. I love easy recipes that call for basic ingredients.
Buttermilk is the only ingredient that we don’t always have on hand, but it is very easy to make. To make buttermilk add 1 tablespoon of an acid like vinegar or lemon juice to 1 cup of milk.
We have a family debate about including nuts in this recipe. Nuts were omitted from a portion of the first batch to the delight of half the family. Plain jumbos taste fine to me but look pretty plain. For the second batch, I included the full amount of nuts and sprinkled a few additional nuts on top to make the banana jumbos look more attractive.
Another old fashioned recipe that our family enjoys snacking on is our Peanut Butter Bread.
Variations of Banana Jumbos
We love chocolate, so I tested a few of these banana bread cookie treats by adding chocolate chips to the top before baking. I’m shocked to share that they tasted fine with the chocolate chips, but I didn’t think the chocolate added very much flavor. The nuts added more to this recipe than chocolate. There’s a phrase I NEVER thought I’d say out loud or type 🙂
