5. Combine the Dry Ingredients:

  • In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and ground cinnamon.

6. Combine the Wet and Dry Ingredients:

  • Gradually add the dry ingredients to the butter mixture, mixing until just combined.
  • Fold in the soaked oats until evenly distributed throughout the batter.

7. Bake the Cake:

  • Pour the batter into the prepared baking pan and spread it out evenly.
  • Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted into the center comes out clean.

8. Cool and Serve:
