All Recipes (www.allrecipes.com) is my favourite place (besides here at BWS) to check for new recipes. One of my favourite things about this site (don't know about others) is that you can change the number of servings and then the recipe automatically changes the quantities of ingredients. Plus I like to read everyone's comments and/or suggestions on how to tweak the recipes. So far, anytime I've tried a recipe that has been popular with lots of other viewers, I've had great success. So that's another place to try...once you get to the site, just type in something like "peanut butter cookie bar" and you should get some good results.
