I have been attempting rhubarb recipes for a very long time since it is one of my favorite summer treats! As a stubborn loser, it was even more important to me to make this dessert an FP! 
The most important thing to remember is to use the THM brand Oat Fiber! Other brands do not compare to the THM brand and will not taste as good as THM! This recipe does have a bit of an Oat fiber texture if you eat it immediately but that improves with refrigeration!
