You will need 3 basic ingredients:
3-5 ripe bananas (2 cups)
(The kind on sale in the produce section if you don't have them as home)
2 cups rolled oats
1 cup nut butter
(Peanut butter, almond butter, sun flower seed butter, etc.)
You mix all of these ingredients in a bowl then spread them into a square pan or rectangular shaped pan. Bake them for 15 minutes on a pre-heated oven at 350 degrees F.
If you have kids or grand kids, you may want to put a twist on this process:
1 small Ziploc bag
1 small/medium banana
1/2 c rolled oats
1/2 c nut butter
Put all the ingredients in the Ziploc bag, and let those little hands smash the bananas until everything is moist.
Let the bags rest on a flat surface at least 15 minutes, and the contents will thicken and take on the shape of the bag as the oats absorb the moisture and expand.
If you tear or cut the bag away, you will already have a rectangular shape to bake. If you scoop the contents out, you can form the shape by hand. In either case, wrap the small rectangular shapes with wax paper or parchment paper like you are wrapping a rectangular sandwich (if you have no idea what I mean, call an older mom or dad).
The kids can individualize their treats by deciding to add nuts, dried fruit, chocolate chips, etc. before the mixture is baked. Alternatively, a drizzle of honey, molasses, or a thin layer of fruit preserves, etc. can add an extra dimension of sweetness to a naturally sweet treat after baking.
Let cool at least 10 minutes before cutting into small squares or bars.
Try this recipe and put your own spin on it. Tray applesauce instead of bananas or a combination of both. Add an envelope of hot chocolate mix or cocoa to the 3 basic ingenious to give it more of an appearance like brownies.
NOTE: I have not used quick oats with this recipe, but you may want to try it for yourself.
