Hot Chocolate Sundae Cake is an ultra decadent chocolate pudding cake that magically creates it’s own hot chocolate sauce as it bakes! Top it off with a generous dollop of whipped cream. It’s even better than warming up to a mug of hot chocolate!
Last winter I bought a hot chocolate maker for Justin’s Christmas present. My boys went crazy over that thing.
I can’t even begin to tell you how many gallons of hot chocolate they drank. And, with each batch of hot chocolate they made, they got a little more creative with add-ins. After all their creativity, they still loved marshmallows and whipped cream the best.
What can I say they are traditional like that! I decided to turn their addiction into a cake…a Hot Chocolate Sundae Cake!
This cake is like grandmas hot fudge sundae cake PLUS it has marshmallows and chocolate chips!
The best part though is the hot chocolate sauce that magically appears while this cake bakes!
How to make Hot Fudge Sundae Cake
STEP 1: Mix dry ingredients together. Set aside.
STEP 2: In a separate bowl, whisk wet ingredients together. I like using a large measuring cup.
STEP 3: Add wet ingredients to dry ingredients. The cake batter will be thick.
STEP 4: Add marshmallows and chocolate chips! Stir.
STEP 5: Spread in a greased 9″ pan. It’s a little tricky to spread the batter because it’s so thick. Don’t worry if it isn’t even or spread clear to the edge.
STEP 6: Mix hot chocolate mix and brown sugar together. Just use the same bowl you used before. It makes dishwashing duty better!
STEP 7: Sprinkle brown sugar mixture over cake. Don’t stir.
STEP 8: Mix two envelopes of Swiss Miss Hot Chocolate with hot water. Pour over the cake but DO NOT stir.
How to serve hot fudge sundae cake
Spoon Hot Chocolate Cake into serving bowls. Make sure you get a little of that hot chocolate fudge!
This cake is super rich and decadent and it needs a hearty dollop of whip or vanilla ice cream to balance out all that sweet!
What I love about Hot Chocolate Sundae Cake
Hot Chocolate Sundae Cake is one of those desserts that everyone loves! It’s a chocolate lovers dream come true!
And I love it because I almost always have the ingredients on hand to make it. And because it simplifies my life and that’s especially important during the holidays!

Hot Chocolate Sundae Cake
Ingredients
- 3/4 cup granulated sugar
- 1/4 cup baking cocoa
- 1 cup flour
- 2 tsp baking powder
- 1/4 tsp salt
- 1/2 cup milk
- 4 Tbsp butter melted
- 1 egg yolk
- 2 tsp vanilla
- 1/2 cup semi-sweet chocolate chips
- 1/2 cup marshmallows
- 1/3 cup brown sugar
- 1/3 cup hot chocolate mix
- 1 cup hottest tap water
Instructions
- Preheat oven to 350 degrees. Spray an 9”x9” pan with nonstick spray.
- To a medium sized mixing bowl add granulated sugar, ¼ cup of baking cocoa, flour, baking powder, and salt. Stir until combined.
- To a separate bowl add milk, melted butter, egg yolk, and vanilla. Whisk until combined.
- Pour milk mixture into the flour mixture. Stir until well combined. Batter will be thick. Add chocolate chips and marshmallows to the cake batter and stir to incorporate. Place cake batter in prepared 9”x9” pan and spread to edges.
- I used to the same bowl used to make the cake batter in for this next step. Add brown sugar and 2 packages Swiss Miss Hot Chocolate envelopes to bowl and mix. Sprinkle brown sugar mixture evenly over the top of cake. Do not stir.
- Measure 1 cup hottest tap water into a measuring cup. Add remaining two envelopes of Swiss Miss Hot Cocoa to water and stir until combined. Pour Swiss Miss hot chocolate over the top of the cake. DO NOT STIR.
- Bake cake for 22-24 minutes. The cake will look a little underdone and that’s exactly how it should look. Marshmallows should be golden brown.
- Cool cake for 10 minutes. Serve warm with a generous amount of Reddi-wip topping.

Hi Amy, I’m curious can you use Trader Joe’s sipping cocoa and just use 12 tablespoons to make up what would be in those packages I think? It’s the only hot cocoa I can use. Just curious. This sounds delicious! 🙂
I’m sure it would be just fine! Merry Christmas!
Sorry, but I have to ask. The little blue bowl in your picture that is on top of the orange bowl. Where did you get it? Who makes it? I must have it
Hi Nancy! I bought that little bowl at Target years ago. They are tiny and perfect for little desserts!
