*Sadly, like all energy bars, not actually suitable to keep you alive as a sole nutritional source. Maybe add an apple.
Step 1: Ingredients
1 cup nutella
1 cup peanut butter
1 cup protein powder
½ cup oats**
½ cup rice flour
1/3 cup almonds
5 Tbs condensed milk
1/3 cup sunflower seeds
¼ Tsp salt
I probably don’t need to say it, but you can of course substitute the choice of gluten free flour, seeds/nuts, add dried fruit, add chilies, go for all-PB or all-Nutella, and generally have fun with it. Just to note, rice flour from an Asian market can be a lot cheaper than a fancy all-purpose gluten-free flour mix from a super market.
Other things you may need or want:
Oven, mixing bowl, cookie sheet, baking/wax paper, press (actual or creative hack)
**Make sure they are gluten free, and if you have trouble with oats, just swap for more flour.
Step 2: Mix to a Pressable Consistency
Mix in nut butters
Mix in condensed milk by the Tbs until the mix reaches a firm-but-sticky consistency
Add in nuts and seeds
Note: If you did want to precisely measure out the peanut butter/nutella, a pre-floured cup can be very helpful. Otherwise, estimating the amount of nut butter and adjusting the consistency with condensed milk is probably easier.
This is a good time to preheat the oven to 175 C / 350 F.
Step 3: Shape 'em
Cubes or spheres can be shaped by hand.
A press can be made out of common items, such as a lunch box and a small cutting board. Make sure to use baking/wax paper on top and bottom to simplify getting the cubes back out.
Step 4: Bake 'em
Bake cubes for 30 min at 175 C / 350 F
Step 5: Eat 'em

Here in Germany, the cost of making one of these is 0.30 EUR, which is less than a 7th of the cost of a cliff bar (for comparable grams and Calories).
Shelf life is at least two weeks (the current record for how long until they have all been eaten).
*with the recipe as is, I must apologize that the cubes will not actually be grey =P
