The brand "Enjoy Life" is free of the most common food allergens. http://www.enjoylifefoods.com/
The Food Allergy Awareness Network (FAAN) has lots of good info, and I think they have a recipes section (some are free, others you have to get membership for in order to get access to).
I hate paying the $$$ for a box of peanut-free granola bars, and after much searching, found a recipe, which I "tweaked":
Easy Granola Bars

"Fantastic bars that have a lot of flexibility - adapt them to your liking! They store well. Use any combination of chocolate chips, dried fruit, coconut, pecans, almond slices, or any other tidbits you'd like in a granola bar."
Ingredients
* 3 cups quick-cooking oats
* 1 (14 ounce) can sweetened condensed milk
* 2 tablespoons butter, melted (use real dairy butter)
* ½ to 1 cup flaked coconut, optional
* 1 cup miniature semisweet chocolate chips or butterscotch chips
* 1 cup sweetened dried cranberries or raisins or blueberries, etc.
* 1 cup of rice crispies
* 1/2 cup wheat germ or whey powder, optional (whey powder will add protein, wheat germ will add vitamins/minerals)
* 1/2 cup ground flax seed (good source of omega 3 fatty acids)
* 1 tsp vanilla
Directions
1. Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13 inch pan.
2. Place the unopened can of condensed milk in a bowl of hot water. Meanwhile, in a large bowl, put oats, coconuts, rice crispies, choc or butterscotch chips, and wheat germ, whey powder and/or flax seed. Mix with a wooden spoon until blended.
3. Melt the butter in a microwave safe, medium sized bowl. Add the condensed milk and stir, then add the vanilla and stir again.
4. Add condensed milk mixture to dry ingredients and stir well with a wooden spoon until well blended.
5. Spoon "batter" into baking pan. Use sheet of wax paper or well oiled hands to press mixture flat into the prepared pan.
6. Bake for 22 to 25 minutes in the preheated oven, depending on how crunchy you want them. Lightly browned just around the edges will give you moist, chewy bars. Let cool for 5 minutes, turn on to rack, cut into squares then let cool completely before serving.
7. Store in a Ziploc bag.
