Creating Chocolate Pudding Cake is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch square baking dish.
2. Mix Dry Ingredients: In a large bowl, combine flour, sugar, cocoa powder, baking powder, and salt. Whisk until well mixed.
3. Combine Wet Ingredients: In another bowl, whisk together milk, vegetable oil, eggs, and vanilla extract until smooth.
4. Combine Mixtures: Gradually pour the wet mixture into the dry mixture. Stir until just combined; avoid over-mixing.
5. Add Chocolate Chips: Fold in the chocolate chips, distributing them evenly throughout the batter.
6. Pour into Dish: Pour the batter into the prepared baking dish, smoothing the top with a spatula.
7. Add Boiling Water: Carefully pour boiling water over the batter. Do not stir; this will create a pudding layer underneath.
8. Bake: Place in the oven and bake for 30 minutes. The top will appear set, but the pudding will be gooey underneath.
9. Cool: Remove from the oven and let cool for 10-15 minutes before serving. The pudding will thicken as it cools.

These steps will guide you in creating this incredible Chocolate Pudding Cake effortlessly. The combination of a rich chocolate cake layer and a luscious pudding layer is truly something to savor.
