Ingredients
For the Chaos Spice Cake
- 2 ½ cups all-purpose flour
- 1 ½ cups granulated sugar
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ½ teaspoon ground nutmeg
- ½ teaspoon ground cloves
- ½ teaspoon salt
- 1 cup (2 sticks) unsalted butter, melted and slightly cooled
- 3 large eggs, room temperature
- 1 cup buttermilk (or whole milk mixed with 1 tablespoon lemon juice)
- 1 teaspoon pure vanilla extract
For the Rich Chocolate Frosting & “Chaos” Topping
- ½ cup (1 stick) unsalted butter, melted
- ⅓ cup unsweetened cocoa powder
- ⅓ cup whole milk
- 1 teaspoon pure vanilla extract
- 4 cups powdered sugar, sifted
- The “Chaos” Topping: A festive mix of holiday sprinkles, red and green M&Ms, crushed candy canes, or mini marshmallows scattered generously over the top
Using buttermilk in the cake batter reacts with the baking soda to create an extraordinarily light, tender crumb that absorbs the rich spices and keeps the cake moist for days.
Instructions
Step 1: Prep the Oven and Pan 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.
Step 2: Whisk the Dry Ingredients In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, ground cinnamon, ground nutmeg, ground cloves, and salt until well combined and free of lumps.
Step 3: Combine the Wet Ingredients In a separate medium mixing bowl, whisk together the melted unsalted butter, eggs, buttermilk, and pure vanilla extract until smooth and uniform.
Step 4: Mix the Batter Pour the wet ingredients into the dry ingredients. Stir gently with a spatula or whisk just until combined and smooth. Do not overmix!
Step 5: Bake to Golden Perfection Pour the batter evenly into your prepared 9×13-inch pan, smoothing out the top. Bake at 350°F for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let cool completely on a wire rack.
Step 6: Make the Chocolate Frosting In a medium saucepan over medium heat, melt the ½ cup of butter and stir in the cocoa powder until smooth. Remove from heat, then whisk in the whole milk and vanilla extract. Gradually whisk in the sifted powdered sugar until the frosting is thick, glossy, and completely smooth.
Step 7: Frost and Create the “Chaos” Pour the warm chocolate frosting immediately over the cooled cake, using an offset spatula to spread it smoothly into all the corners. While the frosting is still warm and soft, scatter your festive holiday mix of sprinkles, M&Ms, crushed candy canes, and mini marshmallows all over the top in a joyful, chaotic display.
Step 8: Set, Slice, and Serve Let the frosting set for 15 to 20 minutes, then cut into neat squares and serve.
Tips for the Best Christmas Chaos Cake
- Frost while the cake is cooled, but frosting is warm Pouring the warm chocolate frosting over a completely cooled cake allows it to spread like a dream before setting into a gorgeous fudgy crust.
- Don’t overmix the batter Stirring the wet and dry ingredients just until combined keeps your spice cake tender and fluffy rather than dense.
- Customize your chaos Embrace the “chaos” by raiding your pantry for whatever holiday baking toppings you love best—chopped nuts, coconut flakes, or colored sprinkles all work wonderfully!
- Sift your powdered sugar Sifting the powdered sugar for the chocolate frosting prevents any powdery lumps from ruining that silky-smooth texture.
Delicious Variations
- Peppermint Chaos Cake Add ½ teaspoon of peppermint extract to the chocolate frosting and top with an abundance of crushed candy canes.
- Toasted Pecan Holiday Cake Fold 1 cup of chopped toasted pecans into the cake batter and scatter extra pecans over the frosted top.
- White Chocolate Snow Chaos Cake Substitute the chocolate frosting with a rich vanilla buttercream and blanket the top in white sanding sugar, mini marshmallows, and silver dragées.
What to Serve With Christmas Chaos Cake
This rich, festive sheet cake acts as a wonderful standalone holiday dessert, pairing beautifully with:
- A tall glass of cold milk or eggnog
- A hot cup of coffee, espresso, or spiced holiday tea
- A mug of rich hot chocolate topped with whipped cream
Make-Ahead Instructions
You can bake the spice cake and frost it up to 2 days in advance. Store it covered tightly at room temperature or in the refrigerator. The spices actually deepen in flavor by the second day, making it an incredible make-ahead option for busy holiday hosts.
Storage
Store leftover chaos cake covered tightly in the refrigerator for up to 4 to 5 days. Let individual slices sit at room temperature for 15 minutes before enjoying so the cake softens back to its perfect tender texture.
