Dana's yummy homemade granola bars

These homemade granola bars are an awesome alternative to store bought ones.
My good 'ol friend, Dana Soprano from Cortland, NY sent me this recipe and a bag of 'em for my birthday. You should feel honored that I am sharing them with you :)

Ingredients
4 cups rolled quick oats
1 cup flour (mix of white and wheat would be healthier)
1 tsp. baking soda
1 tsp. vanilla extract
*2/3 cup nonfat plain yogurt (can also use applesauce)
*may need a bit more if mixture is too dry
1/4 cup honey
1/3 cup brown sugar
2 tbsp. melted butter
2 cups "goodies" (i.e. nuts, chocolate chips, raisins, etc).

Prep
Mix all ingredients together- add a little bit of yogurt if mixture is too dry.
Spread and flatten on a greased 9x13 pan.
Bake at 325-350 for 20 mins.; at 10 mins. take them out and flatten them again to help prevent crumbling.
Let cool to touch, then cut into bars. Let completely cool on a cooling rack.
Individually bag for easy access.

* As per Dana's recommendation, I added flax seed, which makes it a little grainer, but gives you some fiber too.
