We all thought this was "nummy nummy nummy," to quote my daughter. I halved the recipe (before noticing it only called for one egg) because I misjudged the amount of rhubarb I was buying. It turned out great (I beat the egg then only used about half of it, ha ha). I really think the number of servings is misleading. I divided my half-recipe in 8, but two of those portions seemed just right. I believe the number of servings in the full recipe should be 8, not 20.
This was a very yummy and quick to prepare dessert. I used Whole Grain Pancake Mix Whole Grain Pancake Mix and substituted half the sugar for Splenda. My husband loves rhubarb and cobbler and he loved this! I think that next time I will bake it in a 8x8 pan instead of a 9x13 pan because I like it thicker. Thanks for posting!
