Preheat the oven to 350°F (175°C). Grease and flour the baking pan.

In a mixing bowl, combine all dry ingredients and whisk together.

In another bowl, mix all wet ingredients until well combined.

Gradually add the wet ingredients to the dry ingredients and mix until smooth.

Pour the batter into the prepared baking pan.

Bake for 30 minutes or until a toothpick inserted comes out clean.

Let the cake cool before serving.
