[pct-l] high-calorie energy bar recipes?

[Len Glassner]

I like the simplicity and time-saving aspects of using bars as a major
part of my hiking diet.  But it's hard to find off-the shelf bars that
have a high-enough caloric density (let's say > 125 cal./oz.) to make
me willing to carry them.  Power Bar Nut Naturals and Clif Mojo bars
make the cutoff, and can be purchased in volume at OK prices.

I'm wondering if is anyone has a recipe for bars that can be made at
home, and have a verifiable calorie/ounce greater than 125?
