Creating this dish is much like painting a memory, each step a brushstroke on the canvas of your kitchen:

1. Preheat your oven to 350°F (175°C) and prepare your baking dish with a light grease.
2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
3. In a large mixing bowl, cream the softened butter and brown sugar until light and fluffy—let the sound of the wooden spoon against the bowl take you back to simpler times.
4. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
5. Gradually add the dry ingredients to the wet mixture, alternating with the milk, until everything is just combined.
6. Gently fold in the finely ground one gram of pot and, if using, the chopped nuts.
7. Pour the mixture into your prepared dish, smoothing the top with the back of a spoon.
8. Sprinkle a generous dash of cinnamon over the top for that comforting aroma that ties the dish together.
9. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

As you prepare this dish, let the scents take you back to a time when life was a little slower, and the kitchen was the heart of the home.
