You know that feeling when you take a bite of something so rich, so chocolatey, and so utterly perfect that you just have to close your eyes and sigh? That’s exactly what happens with this decadent mores cake you will absolutely devour. Growing up in Chicago with my Polish-American family, dessert was practically a love language. My babcia would make her famous apple cake, and my mom would whip up these gooey chocolate treats that filled our little house on the South Side with the most incredible aroma. This cake is my modern tribute to those cozy, chaotic, and delicious family gatherings—a dessert that feels like a warm hug from the inside out.

Ingredients
Here’s everything you’ll need to create this chocolate masterpiece. Remember, baking is a science, so I recommend measuring everything out before you start.
For the Chocolate Cake:
- 1 and 3/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 2 cups granulated sugar
- 1 and 1/2 teaspoons baking powder
- 1 and 1/2 teaspoons baking soda
- 1 teaspoon salt
- 1 cup buttermilk, room temperature
- 1/2 cup vegetable oil
- 2 large eggs, room temperature
- 2 teaspoons vanilla extract
- 1 cup hot coffee or hot water
For the Topping:
- 2 cups mini marshmallows
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream
- 1/4 cup unsalted butter
Step-by-Step Instructions
Alright, let’s get our hands dirty! Follow these steps, and you’ll be rewarded with the most incredible decadent mores cake you have ever tasted.
- Prep the Oven and Pans: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line it with parchment paper for easy removal.
- Whisk the Dry Ingredients: In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. This ensures there are no lumps and everything is evenly distributed.
- Mix the Wet Ingredients: In a separate bowl or a large measuring cup, whisk together the buttermilk, vegetable oil, eggs, and vanilla extract until well combined.
- Combine and Add Coffee: Pour the wet ingredients into the dry ingredients and mix until just combined. The batter will be thick. Now, slowly pour in the hot coffee (or hot water) and mix on low speed until the batter is smooth and thin. Don’t worry, this is normal! The hot liquid helps bloom the cocoa for a deeper flavor.
- Bake the Cake: Pour the batter into your prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for about 15 minutes.
- Toast the Marshmallows: While the cake is still warm, sprinkle the mini marshmallows evenly over the top. Place the pan under your oven’s broiler for 1-2 minutes. Watch it closely! You want the marshmallows to be golden and puffy, not burnt.
- Make the Ganache: In a small saucepan, heat the heavy cream and butter over medium heat until it just begins to simmer. Remove from heat and pour over the chocolate chips. Let it sit for 2-3 minutes, then stir until smooth and glossy.
- Finish and Cool: Pour the warm ganache over the toasted marshmallows, spreading it gently to cover. Let the cake cool completely at room temperature, or pop it in the fridge to speed things up. The ganache will set into a fudgy, crackly top.

Expert Tips for Success
I’ve made this cake a hundred times, so trust me when I say these tips will make all the difference.
- Don’t Overmix: Once you add the wet ingredients to the dry, mix just until there are no streaks of flour. Overmixing develops the gluten and will result in a tough, dense cake.
- Hot Coffee is Key: Don’t skip the hot coffee! It doesn’t make the cake taste like coffee; it just enhances the chocolate flavor. If you’re not a coffee fan, hot water works, but coffee gives it that extra depth.
- Watch the Broiler: The broiler is your best friend and your worst enemy. It can go from perfectly toasted to burnt in seconds. Stay by the oven and keep an eye on those marshmallows.
- Room Temperature Ingredients: Make sure your eggs and buttermilk are at room temperature. This helps them emulsify into the batter better, creating a smoother, more even crumb.
Variations and Substitutions
This recipe is wonderfully versatile. Here are a few ways to make it your own.
- Gluten-Free: You can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The texture will be slightly different but still delicious.
- Add Some Crunch: Sprinkle some chopped pecans or walnuts over the marshmallows before adding the ganache for a delightful crunch.
- Peanut Butter Twist: Drizzle some melted peanut butter over the ganache for a chocolate-peanut butter dream.
- Extra Gooey: If you love a super gooey texture, add an extra cup of marshmallows. Just be prepared for a messier (but tastier) slice.
Serving Suggestions
This cake is a star on its own, but it loves company. Serve it warm with a scoop of vanilla bean ice cream for the ultimate contrast of hot and cold. A drizzle of salted caramel sauce takes it over the top. For a cozy night in, pair it with a tall glass of cold milk or a hot cup of coffee. It’s also fantastic the next day for breakfast—don’t judge me, you know you want to.
FAQs
Can I make this cake ahead of time?
Absolutely! In fact, I prefer it. You can bake the cake, let it cool completely, and store it in the fridge for up to 3 days. Add the marshmallow and ganache topping just before serving for the best texture. The cake itself gets even more moist and flavorful as it sits.
Can I use a different type of pan?
Yes, you can bake this in two 9-inch round cake pans for a layer cake. Just adjust the baking time to about 25-30 minutes. For cupcakes, bake for 18-20 minutes. Just keep an eye on them and use the toothpick test.
What if I don’t have buttermilk?
No problem! You can make a quick buttermilk substitute. Add 1 tablespoon of lemon juice or white vinegar to a measuring cup, then fill it up with regular milk to the 1-cup line. Let it sit for 5 minutes, and you have perfect buttermilk.
