Making Hot Fudge Pudding Cake is simple if you follow these straightforward steps:

1. Preheat the Oven: Set your oven to 350°F (175°C) and grease an 8-inch square baking dish.
2. Mix Dry Ingredients: In a large mixing bowl, combine the flour, sugar, cocoa powder, baking powder, and salt.
3. Add Wet Ingredients: Pour in the milk, vegetable oil, and vanilla extract. Mix until smooth.
4. Add Chocolate Chips: If desired, fold in the semi-sweet chocolate chips for extra richness.
5. Pour Batter: Spread the batter evenly in the greased baking dish.
6. Prepare Fudge Layer: In a separate bowl, mix together the cocoa powder and sugar. Sprinkle this mixture evenly over the batter.
7. Add Boiling Water: Carefully pour the boiling water over the top of the batter. Do not stir; this will create the fudge layer.
8. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the top is set.
9. Cool Slightly: Allow the cake to cool for about 10 minutes before serving. This will help set the fudge layer slightly.
10. Serve: Dish out warm portions, ensuring to scoop up some of the fudge sauce from the bottom.
