Place all of the ingredients into the food processor and blend on high until it all clumps together in one big clump. This usually takes a few minutes. If your dates are juicy, everything should clump together fairly quickly. However, if your dates are on the drier side, you may need to soak them in water for about 30 minutes to plump them up. Or, you can add chunks of banana into the food processor through the hole in the top until everything starts to stick together (don't add a whole banana at once, just drop in small pieces until the desired consistency is reached). Warning: if you choose to add in the banana, don't remove the covering for the hole in the top until everything has been blending for a minute or two, otherwise, you might end up with cacao powder everywhere! It should look something like this when it's done:
For the next step, you can either use a small, non-stick baking pan or a silicone muffin mold (my personal preference). If you are using a baking pan, press the mixture into the pan until it is flat and even. If using a silicone mold, section off pieces of the dough and press them into the mold (you can use a the underside of a spoon to help flatten them). Then, place either the baking pan or silicone mold into the refrigerator for at least 30 minutes. You can then either cut them into bar size shapes in the baking pan, or simply remove them from the mold. Here's how they look when finished:
3/4 raw walnuts or almonds depending on your preference. I suggest soaking the nuts in a bowl of water for at least 30 minutes prior to use. This removes the naturally occurring protective coating on the outside that can cause digestive distress. Rinse and drain them before use.
1 cup raw cacao powder
1 scoop raw protein powder
Follow the steps for the low-fat version.
1/2 cup melted coconut oil (if your coconut oil is solid, you can warm it on the stove at an extremely low heat setting, in a sauce pan just until it becomes liquid).
Blend the ingredients together in a blender until smooth. Then pour the mixture evenly over the power bars. Sprinkle some dried coconut flakes on top if desired. Cacao nibs are a yummy addition as well. Then place the bars into the Fridge for 30 minutes or until the frosting has solidified. You can them remove them from the mold and place them in a storage container. I recommend keeping these in the fridge, as the frosting melts very easily.
