Ingredients:
For the filling:
- 3 medium sized apples, diced
- 1 teaspoon of cinnamon
- 1 teaspoon of vanilla extract
- 1/4 cup of water
For the base and topping:
- 1 cup of old fashioned rolled oats
- 3/4 cup of whole wheat flour
- 1 cup of pistachios, shelled (raw almonds or walnuts may be substituted, if desired)
- 3/4 teaspoon of baking powder
- 3/4 teaspoon of salt (optional)
- 8 tablespoons (or 1/2 cup or 1 stick) of unsalted butter, at room temperature
- 1/3 cup of brown sugar, packed
Directions:
For the filling:
Wash, peel, and dice the apples. Place them in a small or medium pot, along with the vanilla, cinnamon, and 1/4 cup of water. Bring to a gentle boil, then reduce heat, cover, and simmer on low for about 20 minutes, or until the apples are tender. Let the filling cool slightly, then mash it with a potato masher so it becomes somewhat smooth. Let it cool while a bit more and the filling will thicken a bit as it cools.
For the base and topping:
While the apples are simmering, preheat your oven to 350 degrees Fahrenheit. Line an 8 inch square baking dish with two crisscrossed pieces of parchment paper, leaving an overhang of paper on all sides, pressing the paper down inside the dish.
In a blender or food processor, pulse or puree the oats, whole wheat flour, pistachios, baking powder, and salt until finely ground. Transfer to a medium sized mixing bowl. Stir in the brown sugar. Using a pastry cutter or a fork, cut in the butter and continue to work it in until the mixture resembles coarse crumbs about the size of a pea, and everything is well combined.
Reserve 1/2 cup of the crunch mixture for the topping. Press the remaining crunch mixture into the baking dish, using a straight-sided glass or measuring cup to pack it down evenly.
Spread the apple filling over the bottom crust, distributing it evenly. Scatter the reserved 1/2 cup crunch mixture evenly over the top. Bake until golden, and set in the middle about 35 to 45 minutes.
When it is done, let it cool completely (the cooler it is, the better the bars will hold their shape–I can’t always wait till it’s totally cooled!). Then, holding the overhanging parchment paper, lift the crunch out and transfer it to a cutting board and cut with a sharp knife into twelve bars. Enjoy!
