Ingredients and Substitutions

Cake Batter

• 1 cup all-purpose flour (can be substituted with whole wheat flour for added fiber)
• ¾ cup granulated sugar (brown sugar can be used for a deeper flavor)
• ½ cup milk (any dairy or non-dairy milk works)
• 2 tablespoons unsweetened cocoa powder
• 2 tablespoons oil (vegetable or melted butter)
• 2 teaspoons baking powder
• 1 teaspoon vanilla extract
• ¼ teaspoon salt

Hot Fudge Sauce

• 1 cup packed brown sugar
• ¼ cup unsweetened cocoa powder
• 1½ cups hot water

Optional Toppings

• Vanilla ice cream
• Whipped cream
• Chopped nuts
• Chocolate shavings

Step-by-Step Instructions

Step 1: Preheat the Oven

Set the oven to 350°F (175°C). This ensures an even baking temperature, allowing the cake to rise properly.

Step 2: Prepare the Batter

In a medium mixing bowl, combine the flour, sugar, cocoa powder, baking powder, and salt. Stir to mix the dry ingredients evenly. Add the milk, oil, and vanilla extract, then stir until a thick batter forms. It may seem a little stiff, but that’s completely normal. If mixing becomes difficult, use a metal spoon or spatula to ensure all ingredients are incorporated.

Step 3: Transfer to the Baking Dish

Grease a 9-inch pie plate or a square baking dish with a little oil or butter to prevent sticking. Spread the batter evenly in the dish. Since the cake rises and creates its own sauce, ensure your baking dish has tall sides to prevent any spills.

Step 4: Prepare the Hot Fudge Sauce

In a small bowl, mix the brown sugar and cocoa powder together. Sprinkle this mixture evenly over the cake batter. The next step may seem unusual, but it is key to achieving the fudgy sauce at the bottom of the cake.

Step 5: Add the Hot Water

Gently pour the hot water over the entire surface of the batter. Do not stir. It may look strange, but as the cake bakes, the liquid will sink to the bottom and form a rich, chocolatey fudge sauce.

Step 6: Bake to Perfection

Place the baking dish in the preheated oven. To prevent any accidental spills, you can place a cookie sheet underneath the dish. Bake for 30-35 minutes, or until the top of the cake looks dry and slightly puffed.

Step 7: Serve Warm and Enjoy

Once the cake is done, remove it from the oven and let it cool for about 5 minutes. The best way to serve this dessert is while it’s still warm, allowing the hot fudge sauce underneath to be spooned over each serving. Pair it with a scoop of vanilla ice cream for the ultimate experience.

Beginner Tips and Notes

Understanding the Magic of This Cake

This dessert follows a fascinating baking method where the liquid layer transforms into a luscious sauce underneath the cake. The science behind it is simple: as the cake bakes, the denser batter rises while the hot water and sugar mixture settles and thickens into a rich fudge.

Common Troubleshooting Tips

• Cake is too dry: This could mean it was overbaked. Check at the 30-minute mark and remove from the oven once the top looks firm and slightly dry.
• Sauce is too thin: Let the cake sit for 5-10 minutes after baking. The sauce will thicken slightly as it cools.
• Cake spills over while baking: Make sure to use a dish with high sides, or place a baking sheet underneath to catch any drips.

Helpful Kitchen Tips

• Prepping Ahead: You can measure out the dry ingredients ahead of time and store them in an airtight container. When ready to bake, simply add the wet ingredients.
• Substituting Ingredients: If you don’t have cocoa powder, melted chocolate can be used, though the flavor may be slightly different. If you prefer a dairy-free version, use almond or oat milk instead of regular milk.
• Making a Larger Batch: If serving a crowd, double the ingredients and use a larger baking dish. Just be sure to increase the baking time slightly.

Serving Suggestions

This cake is wonderful on its own, but a few simple additions can make it even more indulgent.

• Classic Vanilla Ice Cream: The contrast of warm cake and cold ice cream is unbeatable.
• Fresh Berries: Strawberries or raspberries add a tart contrast to the rich chocolate.
• Whipped Cream: A light topping that balances the fudginess.
• Chocolate Sauce or Caramel Drizzle: Extra decadence for chocolate lovers.
• Chopped Nuts: Adds crunch and enhances texture.

Storage and Leftovers

How to Store

If you have leftovers, let the cake cool completely before covering it with plastic wrap or transferring it to an airtight container. Store at room temperature for up to two days or in the refrigerator for up to five days.

Reheating Tips

To bring back the warm, gooey texture, reheat individual servings in the microwave for 20-30 seconds. If reheating the entire cake, cover with foil and warm it in a 300°F oven for about 10 minutes.

Freezing Option

While this cake is best enjoyed fresh, it can be frozen for up to two months. Let it cool completely, then store in an airtight container. When ready to eat, thaw overnight in the refrigerator and reheat before serving.
