Oatmeal Flax Breakfast Squares

I'm going through a phase of developing a series of Oatmeal Breakfast Squares that I can "grab and go" for a quick breakfast or a nice treat for a coffee break. This recipe is full of oatmeal, oat bran and flax. They are very thick (a lot of batter for the 8x8 pan), very dense, and very filling. I wont say they are 100% healthy but might be somewhere in the middle. They certainly are 100% delicious!

    1 cup melted butter

    1/2 cup maple syrup

    1 tablespoon molasses

    1/4 cup brown sugar

    2 eggs

    1 teaspoon baking soda

    1 teaspoon cinnamon

    1/2 teaspoon salt

    1 teaspoon pure vanilla extract

    1 1/2 cups old fashioned oats

     ½ cup oat bran

    1 1/2 cups whole wheat flour

    ½ cup flax meal

    ½ cup Greek Style yogurt

    ½ cup half and half (or buttermilk)

    1 teaspoon vinegar (omit if using Buttermilk)

    2 tablespoons Arrowroot Flour

    1/2 large, tart apple, peeled, cored and finely grated

    In a large saucepan, melt together the butter, molasses, sugar, and maple syrup. Bring to a rolling boil and cook for 5 minutes until the mixture thickens enough to coat the back of a wooden spoon. Mix in the grated apple and set aside to cool. Whisk eggs, yogurt, half and half (or buttermilk), and vanilla, mixing well. Add the cooled butter mixture the oats, oat bran, flax meal, cinnamon, flours, baking soda, salt and flour and mix until well combined.

  Spread mixture in a parchment lined 8x8 inch baking dish. Make sure the parchment paper overhangs on all sides. Bake in a 350° oven for 45-50 minutes until golden brown and a tester inserted comes out clean. The finished product should be firm to touch. Cut into 9 squares when cool.
