Everyone loves a classic hot fudge sundae, but you always have to go somewhere special to get one.

Some people like their sundae’s plain while others like them a little more dressed up. No matter which way you like to eat your sundae’s, you can customize this recipe too to fit your taste. Chopped nuts can be added to the batter along with the chocolate chips or even sprinkled over the top to add a nice nutty flavor. Vanilla ice cream is a perfect topping to this dessert, and adding a caramel or fruity drizzle followed by whipped cream really brings this recipe to the next level.
This is one of the best dessert recipes that you could make.

How to Make Hot Fudge Sundae Cake
FIRST STEP: Preheat oven to 350°F.
SECOND STEP: In an 8x8 glass baking dish, mix together flour, ¼ cup cocoa powder, granulated sugar, and baking powder.
THIRD STEP: Mix in milk, butter, and vanilla extract until a thick batter forms.
FOURTH STEP: Stir in chocolate chips and spread the batter evenly in the baking dish.
FIFTH STEP: Combine remaining ¼ cup of cocoa powder and brown sugar and sprinkle over the batter.
SIXTH STEP: Pour hot water over the top of all ingredients.
SEVENTH STEP: Bake for 40 minutes or until the cake has formed a dry top and a bubbly, pudding-like bottom.
EIGHTH STEP: Remove from oven.
NINTH STEP: Serve warm cake with ice cream if desired. Top with whipped cream and a cherry!
There is supposed to be a lot of sauce on the bottom. If you want yours less runny and more set up, use less water on the top. Cut ¼ cup water and see if it makes the consistency less runny.
Make this recipe ahead of time and store in the fridge. Just wait to add the hot water until right before you pop it in the oven.
Keep in mind that if you are adding some sort of harder candy like M&M’s, Reece’s, etc, they may sink to the bottom and become part of the sauce. Also, pulling the cake out of the oven halfway through baking could cause it to not set up correctly, so be aware of that too.

IN THE FREEZER: Allow cooling completely before storing. Store in an airtight container for up to 3 months in the freezer. Allow to defrost before reheating, or serve it up frozen!

I have made the Betty Crocker version of this for years, but it doesn’t have the Chocolate chips added. I think the chocolate chips gives it an even better taste. Thank you for sharing this recipe. It’s wonderful!

Thank you for this recipe! I used almond flour instead of all-purpose flour and Splenda instead of sugar and it still turned out perfect. We ate it warm with vanilla ice cream! Yummy!
Could you add some cornstarch to make the sauce thicker?
Yes, you can add cornstarch to make thicker.
Opps, realized I don't have a 8" glass pan. Can I use a my 9/13 & double the recipe? Also can I replace the water for coffee?
Yes, you should be able to double the recipe and use a 9x13. Since it's a different amount, just watch the cook time and make sure it's done. You may need to add a few minutes of cook time. As far as substituting coffee for water, that should be totally fine! It's still a clear liquid so it should work just the same!
OMG.....made this tonight. So good! Super easy & so chocolate-gooey. 💜
Omg...i can't wait to try this too
I’ve been making this recipe for many years and always a hit.
