If you are looking for a healthy alternative to sugar and do not like the idea of using artificial sweeteners, baking with agave nectar might appeal to you. Taken naturally from the agave plant with minimal processing, it is very sweet and is most similar to honey in flavor and texture. Some darker agave can taste more of caramel. Agave is very easy to substitute for any other sweetener normally used in baking.
Preheat the oven to 350 degrees F. Cover a cookie sheet with parchment paper or coat it with a non-stick spray.
Mix flour, agave nectar, butter, baking powder and vanilla in a bowl. Stir until all of the ingredients are incorporated.
Add one egg and stir until it is incorporated into the mixture. Mix in the oats, chocolate chips and chopped walnuts (optional). Mixing the ingredients should form a dough.
Form globs of dough that are roughly ball-shaped with two soup spoons. Drop them onto the prepared cookie sheet. Space the cookies about 1 inch apart. Space the outermost cookies 1 inch from the edges of the cookie sheet.
Slide the cookie sheet into the oven when it has finished preheating. Set the oven timer for 12 minutes and check for doneness. Cookies will be done when they are still slightly soft if you touch their tops, but mostly solid. Slide them back into the oven for another minute or so if they are not done.
