Ingredients:

7 scoops whey protein powder (I use 6 chocolate and 1 vanilla)
2 cups oats (old fashioned oatmeal)
4 medium bananas
1/4 cup chunky natural peanut butter
1 cup splenda
1 tsp salt
~6 almonds
cinnamon and nutmeg to taste
cooking spray

Start by grinding up 1 cup of the oatmeal in a blender.  Blend for about a minute until you have "oat flour".

Add the oat flour to a large bowl along with the remaining oats, the splenda, salt, and protein powder.  Add in a little cinnamon and nutmeg if so inclined (don't overdo it here). Mix.

Slice the bananas into the blender and puree. Add the almonds (optional) and blend just enough to break them up.  Add the peanut butter and blend just enough to mix. 

Add the banana/peanut butter puree to the dry ingredients and mix well.

Cut 6 pieces of aluminum foil no more than 10 inches wide. Lightly coat the insides with cooking spray. Spoon out the mixture evenly.  Fold each into a bar and put on a cooking sheet.

Bake in a preheated oven at 350 deg F for exactly 16 minutes, 30 seconds. It's absolutely key that you don't cook them longer than this, at least if you're cooking them in my oven. You may have to adjust slightly but the easiest way to ruin this recipe is to overcook the bars and turn them in to dry, hard bricks.  Undercooking will produce an unsatisfyingly gooey bar that doesn't keep. If you are going to keep these bars around for much longer than 10 days, I recommend refrigerating.
