To begin, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and grease a 9x13-inch baking pan. In a large bowl, combine the oats and boiling water, and let the mixture stand for 10 minutes.

In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt. Add this mixture to the oats and stir until well combined. Then, add in the applesauce, honey, brown sugar, eggs, and vanilla extract. Stir until all the ingredients are thoroughly incorporated. If desired, fold in the chopped nuts.

Pour the batter into the prepared baking pan and smooth the top with a spatula. Bake the cake for approximately 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Once the cake is done, remove it from the oven and allow it to cool before cutting into squares and serving.
