My wife said I had to write this one down, so here it is.
Turn oven to 350
Mash 3 ripe bananas
Add 1 cup milk, 2 tsp vanilla, 1 tsp pumpkin pie spice, 1 tsp apple pie spice, 1 tsp baking powder, 1/2 tsp salt
Add 1 15 oz can pumpkin puree (not pie filling)
Add 1/2 cup unsweetened applesauce
Add 1/2 cup nuts (walnuts, pecans, sunflower seeds)
Add 2 diced apples (cored and peeled)
Add other dried fruit or cocunut (no more than 1/2 cup)
Add 3 cups Old Fashioned Oatmeal
Line 13x9 cake and brownie baking pan (pyrex) with wax paper
Spray wax paper with spray oil
Put the bar ingredients in lined pan
Layer 2 sliced apples on top of mix, push into bar material slightly
Put in oven
Bake for 30 minutes - you want the the bars to start to brown and pull away from the sides
This will be slightly sweet, but not hugely sweet. If you cut that into 20 even sized bars, it's about 70 calories a bar.
If you use almond milk or the like, use the unsweetened variety.
