Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.
In a medium bowl, combine the rolled oats with boiling water. Stir and let sit for 20 minutes to soften the oats.
In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and ground cinnamon. Set aside.
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs, one at a time, then stir in the vanilla extract.
Add the softened oat mixture to the creamed butter and sugar mixture, stirring until well combined.
Gradually fold in the dry ingredients, mixing just until incorporated.
If using, gently fold in the chopped walnuts.
Pour the batter into the prepared baking pan, smoothing the top with a spatula.
Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.
Allow the oat cake to cool in the pan on a wire rack before cutting into squares and serving.
