Creating Hot Fudge Pudding Cake is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish.
2. Mix Dry Ingredients: In a large mixing bowl, combine the flour, 1 cup of sugar, cocoa powder, baking powder, and salt. Whisk until well mixed.
3. Add Wet Ingredients: Stir in the milk, vegetable oil, and vanilla extract. Mix until smooth and combined.
4. Pour into Baking Dish: Pour the batter into the prepared baking dish, spreading it evenly.
5. Add Boiling Water: Carefully pour the boiling water over the batter. Do not stir; this will create the fudge layer.
6. Sprinkle Chocolate Chips: If desired, sprinkle the chocolate chips evenly over the top.
7. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is set and a toothpick inserted in the cake layer comes out clean.
8. Cool Slightly: Remove from the oven and let cool for about 10-15 minutes before serving.

These steps will guide you in creating this incredible dessert effortlessly.
