How to Make Rich Hot Fudge Sundae Cake

1. Preheat & Prep Preheat oven to 350°F (175°C). Grease a 9×9-inch or 8×8-inch baking dish (glass or ceramic works great).
2. Mix the Cake Batter In a medium bowl, whisk together flour, sugar, cocoa, baking powder, and salt. Stir in milk, oil, and vanilla until smooth — it will be thick like brownie batter. Spread evenly into the prepared dish.
3. Create the Fudge Layer In a small bowl, mix brown sugar and cocoa powder. Sprinkle this mixture evenly over the batter (do NOT stir!).
4. Pour & Bake Carefully pour the hot water over the top — it will look messy, but trust the magic! Do not stir. Bake 35-40 minutes until the top is set and springs back lightly, but the center still has that glorious jiggle. The fudge sauce will bubble up around the edges.
5. Cool Slightly & Serve Warm Let rest 10-15 minutes (sauce thickens as it cools a bit). Scoop generous portions into bowls — make sure each gets plenty of that rich fudge bottom!

How to Turn It Into the Ultimate Sundae

• Place a warm scoop of cake in a bowl or on a plate
• Top with a big scoop of vanilla ice cream (it starts melting instantly — perfection!)
• Add a swirl of whipped cream
• Drizzle generously with extra hot fudge
• Shake on sprinkles
• Crown with a bright red cherry

Dig in immediately while everything is warm and melty!

Pro Tips for Sundae Cake Success

• Use very hot water — almost boiling — to help the sauce form properly.
• Don’t overbake; the center should still look slightly underdone for maximum gooeyness.
• Make ahead: Bake earlier in the day, cover, and reheat individual portions in the microwave for 20-30 seconds before topping.
• Gluten-free version: Swap flour for a 1:1 GF blend.
• Double the recipe in a 9×13 pan for bigger crowds — increase bake time by 5-10 minutes.

This Rich Hot Fudge Sundae Cake is pure chocolate comfort in every bite. Warning: It disappears fast!
