1. The Gemara Brachot 37a quotes the Briatta which says that the Bracha for raw grain is HaAdama. S"A 208:4 rules if the grain was raw or cooked whole it is Haadama.
Halachos of Brochos (pg 505) and Vezot HaBracha (chap 12, pg 103) quoting Rav Elyashiv rule that granola is HaAdama. Halachos of Brochos (pg 505, note 62) explains that granola is made from oats which are steamed and then roasted in the oven. He quotes Rav Shlomo Zalman who said that the steaming is not equivalent to cooking. Since granola is a grain which isn't cooked the Bracha remains HaAdama. The main ingredient in granola is rolled oats (as in Quaker Oat natural granola).
The first four ingredients of the Chocolate Chip Peanut Crunch Clifbar are: Organic Brown Rice Syrup, ClifPro® (Soy Rice Crisps [Soy Protein Isolate, Rice Flour, Barley Malt Extract], Organic Soy Flour, Organic Roasted Soybeans), Organic Rolled Oats, Organic Toasted Oats (Organic Oats, Organic Dried Cane Syrup). Most of them have the same or similar first four ingredients. None of the ingredients include flour other than the Cool Mint Chocolate which has oat flour as part of the sixth ingredient.
Since the ingredients are listed in order, with the ingredients used in the greatest amount first, rolled oats aren't the majority. Nonetheless, since they are the primary ingredient being enhanced by the others, the bracha should be HaAdama (S"A 212:1). The bracha is not Mezonot because of the rice flour since it's not the majority (S"A 208:7). I personally heard from Rabbi Goldberg at the Kof K that the Kof K holds that the Bracha on Clif Bars is HaAdama.
2. Tosfot 37a D"H HaKoses has a doubt that perhaps the Bracha Achrona for raw grain is Al HaAdama. However, Rosh 6:9 and Rambam 3:2 reject this doubt and rule that the Bracha is Boreh Nefashot. S"A 208:4 rules like the Rambam but adds that some say one should be strict and only eat it in a meal. Mishna Brurah 208:18 writes that after the fact if one ate a Kezayit of raw grain one should make Boreh Nefashot.
Vezot HaBracha (pg 103) writes that an alternative is to eat less than a Kezayit in Kedi Achilat Pras. Aruch HaShulchan 208:9 and Kaf HaChaim 208:30 write that another alternative is to have a food that's certainly Mein Shalosh and something that's certainly Boreh Nefashot and together it will exempt the raw grain.
3. Most Builder's Bars have the following first 6 ingredients: Soy Protein Isolate, Beet Juice Concentrate, Organic Brown Rice Syrup, Organic Evaporated Cane Juice, Palm Kernel Oil, Organic Rolled Oats. In all of them there's no grain other than rolled oats and simply oats in the lemon bar. I asked Rav Hershel Schachter and he seemed to side with the approach that the Bracha would be Shehakol because rolled oats isn't a grain and also the oats aren't the primary ingredient of the bar (as opposed to a granola bar) nor is it the majority. Rabbi Gersten from the OU agreed that the Bracha is Shehakol.
4. Rabbi Heber at the Star K writes that Nature Valley bars are Mezonot and Al HaMichya because the grain is considered sufficiently processed. (http://www.star-k.org/kashrus/kk-brochosforbreakfast-fall06.htm)
5. Rabbi Heber at the Star K writes that it's Mezonot because the granola used in the Quaker Granola bars is considered sufficiently processed. (http://www.star-k.org/kashrus/kk-brochosforbreakfast-fall06.htm)
6. The Kof K writes that since the main ingredient is rice flour the Bracha is Shehakol. (http://www.kof-k.org/Facts.php#79)
7.The OU said that the correct bracha is Shehakol and Boreh Nefashot because the primary ingredients are the chocolate and soy and not the rice crisps or whole oats.
