Step‑by‑Step Instructions for Indulgent Self-Saucing Hot Fudge Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C) while you prepare the pan. Grease a 9-inch square baking pan with butter or cooking spray to ensure easy removal of the hot fudge cake later. This initial step sets the stage for the delightful baking process.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, and salt until well blended. The dry mix should be uniform and free of lumps, ensuring even baking later on. Take a moment to enjoy the rich cocoa aroma!
Step 3: Combine Wet Ingredients
Pour in the milk, vegetable oil (or melted butter), and vanilla extract into the bowl with the dry ingredients. Stir gently until a smooth batter forms, free of lumps. The mixture should be creamy and inviting, capturing the essence of a delicious hot fudge cake ready for the baking pan.
Step 4: Pour and Level the Batter
Carefully pour the batter into the prepared baking pan, spreading it evenly with a spatula. This step is crucial to ensure that the cake bakes uniformly. Smooth the top so it’ll be nice and even, setting the stage for the heavenly self-saucing effect.
Step 5: Add Toppings
Sprinkle the unsweetened cocoa powder and light brown sugar evenly over the batter. Then, slowly drizzle boiling water over the entire surface, taking care not to disturb the layers below. The magic begins here; do not stir! This will help create the luscious sauce while baking.
Step 6: Bake to Perfection
Place the pan in the preheated oven and bake for 35-40 minutes. The top should look set and slightly cracked while the cake underneath remains wonderfully fudgy. Make sure to peek in at the 35-minute mark for signs of doneness; it should be bubbling and inviting!
Step 7: Rest and Serve
Once baked, remove the hot fudge cake from the oven and let it rest for about 10-15 minutes. This resting time allows the sauce to thicken, enhancing the irresistible gooeyness. Serve warm, preferably with a scoop of vanilla ice cream to complete this delicious dessert experience.

How to Store and Freeze Hot Fudge Cake
Fridge: Store leftovers in an airtight container for up to 5 days. This keeps your cake fresh and allows you to indulge in its gooeyness later.
Freezer: To freeze, wrap the cooled hot fudge cake tightly in plastic wrap and then in aluminum foil. It can be stored like this for up to 3 months.
Thawing: When you’re ready to enjoy it again, simply thaw it overnight in the refrigerator for the best results.
Reheating: For a delightful experience, reheat individual slices in the microwave for about 20-30 seconds or place the whole cake in a low oven until warmed through.
