Making Chocolate Pudding Cake is a delightful process. Follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch square baking dish.
2. Mix Dry Ingredients: In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until the mixture is smooth and well combined.
5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips.
6. Add Boiling Water: Carefully stir in the boiling water. The batter will be thin, but this helps create the pudding effect.
7. Pour into Pan: Pour the batter into the prepared baking dish.
8. Bake: Place the dish in the preheated oven and bake for 30-35 minutes. The top should be set, and a toothpick should come out clean when inserted into the center.
9. Cool: Remove from the oven and let it cool in the pan for 15-20 minutes before serving.

These steps will lead you to an incredible Chocolate Pudding Cake that is sure to impress.
