Ingredients

- Flour: Opt for your regular all purpose flour here. Gluten free flour may not work well.
- Sugar: To sweeten! White granulated sugar works well. You’ll also need some brown sugar for the fudge sauce.
- Cocoa powder: Use the best quality cocoa powder you can find- it really makes a difference in the end result. If you prefer a slightly bitter, darker flavor, use dark cocoa powder, and if you prefer a sweeter, subtle flavor, Dutch process cocoa powder is your best bet!
- Butter: For the richness. I love using salted butter.
- Milk: To add moisture and richness to the batter. Use whole milk for the most indulgent taste.
- Baking powder: To help the cake rise.
- Vanilla: For that delicate sweet flavor and aroma.

How To Make Hot Fudge Chocolate Pudding Cake

- Prepare cake batter: In a bowl, combine milk, butter, all purpose flour, baking powder cocoa powder, sugar and vanilla. Whisk it all until you get a smooth batter.

- Add batter to pan: Pour this batter into the prepared baking pan and tap lightly to remove any air bubbles.

- Prepare the sauce: In another bowl, combine the remaining white sugar, brown sugar and cocoa powder and sprinkle this over the batter.

- Pour water: Once the water in the kettle is boiling, pour it over the cake (don’t stir!) slowly and allow it to sit on the top.

- Bake time: Pop the pan in the preheated oven and let the cake bake for about 35 minutes. Remove from the oven and let it cool for 15 minutes or so.

- Finish up and serve: Top the chocolate pudding cake with some whipped cream or ice cream, spoon some of that fudge sauce over the top, and serve.
Serve this hot fudge pudding cake on its own, or pair it with some toppings of your choice. Ice cream, whipped cream and fresh fruits are great! Sometimes, I also like to pair it with my Drunken Chocolate Covered Strawberries.
And if I have some leftover Mini Chocolate Chip Greek Yogurt Cookies, I top some of them too!
Recipe FAQ’s
Check the cake at the 30-35 minutes mark. That’s the sweet spot where you will have a firm looking top and a nice bit of sauce on the bottom.
For a richer, deeper chocolate flavor, use dark or Dutch-process cocoa powder. Regular unsweetened cocoa works fine too but may be lighter in flavor.
The boiling water helps create the self-saucing fudge layer underneath the cake as it bakes. Don’t skip or stir it in!

Notes
*Cocoa powders: A dark cocoa powder will yield in a rich and bitter-sweet chocolate flavoured pudding (pictured in the first photographs above).
A normal unsweetened cocoa powder, such as Hershey’s unsweetened, will yield a milder chocolate flavoured pudding — not bitter in taste and still rich (photographed in the last images above). Please choose carefully, and use a cocoa powder you LOVE the taste of.
