Baked Oatmeal Cinnamon Squares

Preheat oven to 350 degrees F. Spray a brownie pan with cooking spray. Combine flour, oats, baking soda, salt, cinnamon, and brown sugar in a large bowl. In another bowl, whisk together butter, granulated sugar, egg white, vanilla extract, and Greek yogurt until smooth. Pour wet mixture into dry mixture and stir until batter is combined. Pour the oat mixture into the pan and bake for 20-25 minutes, or until the tops of the bars turn golden brown. Remove from the oven and let cool in the pan for 5 minutes. Let stand on a wire rack for 15 minutes before serving, or serve hot immediately.

Makes 12 bars.
