- 1/2 tsp Baking soda: Balances acidity and helps the cake rise even more.
- 1 tsp Salt: Enhances the sweetness and brings together the chocolate flavors.

- 1 3/4 cup White granulated sugar: Sweetness plays a crucial role in balancing the chocolate and adding delightful moisture.
- 1 tsp Pure vanilla extract: Adds depth of flavor that perfectly complements the chocolate.
- 4 Large eggs (room temperature): Binds the ingredients together and adds richness. Make sure they are at room temperature for best results.
- 1 cup Buttermilk (room temperature): Contributes to the cake’s moistness and tender crumb; sour cream can be a substitute in a pinch.
- 1 cup Water: Ensures a rich and moist batter, activating the cocoa flavor even more.
- 1 cup Unsweetened cocoa powder (sifted): The star of our show, providing the signature rich chocolate flavor.
- 1/3 cup Hot cocoa mix: Adds sweetness and a burst of that familiar hot chocolate flavor.
- 20 Marshmallows: These little puffs of joy melt into gooey goodness between the cake layers.
- 3/4 cup Heavy cream: Used for making the luscious hot cocoa frosting that adds a creamy touch.
- 2/3 cup Hot cocoa mix: Enhances the frosting’s flavor, tying it perfectly to the cake.
- Pinch of salt: Just a hint to balance the sweetness of the frosting.

How to Make Hot Cocoa Cake
Preheat and Prepare: Start by preheating your oven to 350℉. Spraying three 8-inch cake pans with nonstick baking spray and lining the bottoms with parchment paper will help your layers to come out perfectly. A quick spray on top after placing the parchment ensures nothing will stick, giving you that beautiful, flawless surface for your **hot cocoa cake**.
Combine Dry Ingredients: In a medium bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. This step is crucial, helping to aerate the flour and ensuring an evenly mixed batter without any lumps. The dry ingredients need to be blended to keep your cake velvety!
Heat Chocolate Mixture: In a saucepan over medium-high heat, mix the sifted cocoa powder, water, and hot cocoa mix. Stir meltingly until you achieve a hot, simmering mixture that makes the house smell like a chocolate paradise. Once it’s hot, set it aside to cool slightly—this will help you distribute that rich chocolaty goodness throughout your cake.
Whisk Wet Ingredients: In a large mixing bowl, combine the oil, sugar, vanilla extract, eggs, and buttermilk. You want everything to be at room temperature for the best mixing results. Whisk vigorously until the ingredients meld into a smooth, rich batter. Slowly add in your warm chocolate mixture and blend well.
Mix Together: Next, gently fold in the sifted dry ingredients. Start on low speed until just combined and continue until no flour lumps remain. This should only take about a minute, so don’t overmix—it’s essential for keeping the texture light!
Pour and Bake: Divide the batter evenly between your prepared cake pans. Bake in your preheated oven for 20-23 minutes. The key is to pull the cakes out when they are almost done; a toothpick inserted should have some moist crumbs attached, indicating it’s just shy of perfection. Fun fact: add 10 marshmallows to the top of two of your cake layers for that extra bit of indulgence.
Cool and Squish: After baking, allow the cakes to remain in their pans for about 10 minutes before gently transferring them to a cooling rack. The marshmallows should be popped down as they cool, creating a delectable, gooey filling inside your cake layers. Be sure to cool them completely before frosting.
Heat the Heavy Cream: For the frosting, combine heavy cream, cocoa mix, and a pinch of salt in a medium saucepan over medium heat. Stir until it thickens slightly and the sugar dissolves. Let it cool completely—this is your hot cocoa cream, and as it cools, it will thicken perfectly for frosting.
Mix the Frosting: In a separate bowl, sift together powdered sugar and cocoa powder. Beat the softened butter on high speed for about three minutes, ensuring it’s creamy. Gradually add half the powdered sugar, mixing on low speed until just combined before adding the remaining sugar and the rich chocolate cream. Beat the mixture until it turns velvety and smooth.
Assemble Your Cake: Begin by placing the first layer of the cake (the one with marshmallows) upside down onto your cake stand. Spread 3/4 cup of frosting generously over it to create a delicious filling. Repeat this process with the second cake layer, introducing additional scrumptious frosting. Finally, cap it off with the last cake layer, creating a lovely three-tiered masterpiece.
Crumb Coat and Frost: Apply a light layer of frosting around the sides to set a crumb coat, and then pop the whole cake into the freezer for about 15 minutes. This will firm it up for your final frosting layer, giving a polished appearance. Once chilled, frost the rest of the cake with the remaining frosting, ensuring smooth edges, and top with extra marshmallows and crushed candy canes for that festive flair!

Storing & Reheating
To enjoy your hot cocoa cake at its best, store it at room temperature for up to two days. If you need it to last longer, cover it tightly with plastic wrap and place it in the refrigerator, where it can last up to a week. For longer storage, wrap individual slices or the whole cake in plastic wrap and aluminum foil before freezing it for up to three months. When you’re ready to savor your creation again, simply thaw it in the fridge overnight and reheat individual slices in the microwave for about 10-15 seconds to melt that marshmallow center back to gooey perfection.
