Preheat oven to 270F. Lightly grease a large glass baking dish*
Add all dry ingredients together and stir. Make well in center. Set aside.
In an at least 2 cup measuring cup, measuring maple syrup, and add in vanilla and maple flavoring. Stir. Pour into center of dry ingredients and mix well.
Spread into prepared glass baking dish.
Bake for 1 hour. Stir. Bake for 30 minute. Stir. Bake for another 30 minutes. Stir again. I find that this is perfect for me, but if it's not dark enough for you after the second 30 minutes, just repeat until it is!
Cool completely and store in airtight container or ziploc bag.
*The original recipe calls for 2 Tbsp vanilla and 1 Tbsp Maple flavoring, but I my mom changed it to what I have listed, and I LOVE it that way!
