Ingredients You’ll Need

All-purpose flour: Essential for structure; feel free to substitute with a gluten-free flour blend if needed.
Cornstarch: This helps create a lighter texture; you could swap it for an equal amount of flour.
Baking powder & baking soda: These leavening agents help your cake rise and become fluffy.
Salt: A pinch of salt enhances sweetness and balances flavors.
Canola or vegetable oil: Adds moisture; melted butter could be used as an alternative for a richer flavor.
White granulated sugar: The sweetness is perfect for our dreamy hot cocoa theme; brown sugar will give a distinct flavor.
Pure vanilla extract: Enhances the overall flavor; avoid imitation vanilla for a more aromatic result.
Eggs: Room temperature eggs mix better for a smoother batter; you can substitute with flax eggs if vegan.
Buttermilk: Adds moisture and tenderness; you can sour regular milk with vinegar for a quick substitute.
Water: Used to prepare the hot cocoa mix, it keeps the cake moist.
Unsweetened cocoa powder: Essential for that deep chocolate flavor; be sure to sift it for a smoother cake.
Hot cocoa mix: This brings the hot chocolate essence right into the cake — perfect for flavor! There are different brands available, so choose your favorite.
Marshmallows: They create that nostalgic hot cocoa feeling by adding gooeyness between layers and on top.
Heavy cream: Required for the hot cocoa frosting, it gives richness. You can use coconut cream for a dairy-free version.
Powdered sugar: Essential for sweetening the frosting; ensure it’s sifted for a smoother texture.
Pinch of salt: Just a hint brings out the sweetness in the frosting and strengthens the flavors.
Unsalted butter: Room temperature butter creates a creamy texture for the frosting, while salted butter can be used for additional flavor.

How to Make Hot Cocoa Cake

Preheat and Prepare: Start by preheating your oven to 350℉. Prepare three 8-inch cake pans by spraying them with nonstick baking spray and lining the bottoms with parchment paper, then spray again to ensure an easy release.

Combine Dry Ingredients: In a medium bowl, sift together the all-purpose flour, cornstarch, baking powder, baking soda, and salt. This blend will ensure your cake has a light and fluffy texture, so don’t skip this step!

Whisk Wet Ingredients: In a saucepan over medium-high heat, combine the sifted cocoa powder, water, and hot cocoa mix. Stir until it’s hot and simmering, then remove from heat and set aside. In a large bowl, whisk together the oil, sugar, vanilla, eggs, and buttermilk until fully combined.

Mix It All Together: Add the hot cocoa mixture to the wet ingredients, mixing well. Gradually incorporate the dry ingredients into this mix, stirring on low speed until just combined and no flour lumps remain. Be careful not to overmix, or your cake could become dense!

Pour and Bake: Divide the batter evenly between the three prepared cake pans. Bake for 20-23 minutes, or until a toothpick inserted into the centers comes out with moist crumbs. Just before the cakes are fully done, take two of the pans out, and place 10 marshmallows on top of each. Return to the oven for an additional 2 minutes until the marshmallows soften.

Cool: Let the cakes cool in the pans for about 10 minutes. After that, take them out and transfer them to a wire rack, marshmallows facing up. Allow them to cool completely before decorating. This ensures your frosting won’t melt!

Make the Frosting: In a saucepan over medium heat, combine the heavy cream, cocoa mix, and a pinch of salt. Stir continuously until it thickens and the sugar melts, which should take about 5 minutes. Set aside to cool properly; it will thicken more as it cools, creating the perfect consistency for frosting.

Beat the Butter: In a large bowl, sift together the powdered sugar and cocoa powder. Using a hand mixer, beat the room temperature butter on high speed for about 3 minutes, ensuring it’s creamy and fluffy. Add in half of the powdered sugar and mix on low speed until just combined. Then add the rest of the sugar, the cooled cocoa cream, and the vanilla extract, mixing until you achieve a smooth, creamy frosting.

Assemble the Cake: Place the first cake layer, marshmallow side down, onto a plate or serving stand. Spread even frosting of about 3/4 cup over this layer. Next, place the second marshmallow layer on top and repeat the frosting process. Add the last layer, ensuring it’s right side up. Coat the sides with a light crumb coat of frosting and freeze for about 15 minutes to set before applying a final, thicker layer of frosting.

Decorate: Once the cake is frosted, feel free to decorate the top with more marshmallows and even crushed candy canes for a festive flair. The visual appeal will be a hit at any gathering!

Storing & Reheating

To keep your Hot Cocoa Cake fresh, store it at room temperature for about two days, covered loosely with foil or in a cake dome to maintain moisture. If refrigeration is needed, it can last up to a week in an airtight container, allowing it to maintain its delightful flavors. For longer storage, you can freeze the layers individually wrapped in plastic wrap and stored in a heavy-duty freezer bag for up to 3 months. When you’re ready to enjoy, simply allow it to thaw in the fridge overnight and bring it to room temperature before serving. Note that while the cake may lose some moisture, a simple re-frosting can help bring it back to life!

Chef’s Helpful Tips

Be careful not to overmix your batter; this can lead to a dense cake.
Use room temperature eggs and buttermilk for an easy blend and better rise.

Top with hot cocoa mix for decoration or crushed peppermint for a holiday twist.
Make the cake layers ahead of time and assemble them the day you plan to serve for a quick, stress-free dessert.

Each time you savor a slice of this Hot Cocoa Cake, may it bring warmth and joy reminiscent of cozy winter nights.

Recipe FAQs

Can I make this Hot Cocoa Cake in advance?

Absolutely! You can bake the cake layers up to three days ahead. Just wrap them in plastic wrap once completely cooled and store them in the refrigerator. This makes assembly easier on the day of your event, ensuring freshness without last-minute stress.

How do I know when my cake is fully baked?

A toothpick inserted into the center of the cake should come out clean or with a few moist crumbs attached. If it’s wet with batter, give it a couple more minutes in the oven. Remember, you want it to be almost done when you add the marshmallows; they finish cooking with the cake’s residual heat.

Can I use a different type of cocoa powder?

Yes! While unsweetened cocoa powder is recommended for a rich chocolate flavor, you can also use Dutch-process cocoa for a slightly different taste. Just be sure it’s unsweetened as well, otherwise, the sweetness will alter the intended flavor profile of the cake.

What if I don’t have buttermilk?

You can easily make your own buttermilk by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5–10 minutes to thicken before using it in your recipe, and it should work perfectly!
