# The Ingredients You'll Need:

→ Cake

01 - 2 cups granulated sugar
02 - 2 cups all-purpose flour
03 - 1/2 teaspoon salt
04 - 1 cup Coca-Cola (not diet)
05 - 1 cup unsalted butter (2 sticks)
06 - 1/4 cup unsweetened cocoa powder
07 - 2 large eggs
08 - 1/2 cup buttermilk
09 - 1 teaspoon baking soda
10 - 1 teaspoon vanilla extract
11 - Optional: 1 cup mini marshmallows

→ Chocolate Frosting

12 - 1/2 cup unsalted butter (1 stick)
13 - 1/4 cup Coca-Cola
14 - 1/4 cup unsweetened cocoa powder
15 - 3 1/2 to 4 cups powdered sugar, sifted
16 - 1 teaspoon vanilla extract

# Step-by-Step Instructions:

01 - Preheat oven to 350°F. Grease and flour a 9x13-inch baking dish or line with parchment paper, ensuring corners are well covered.
02 - Whisk together flour, sugar, and salt in a large bowl; set aside.
03 - In a medium saucepan over medium heat, combine butter, cocoa powder, and Coca-Cola. Stir constantly until melted and mixture reaches a gentle boil.
04 - Immediately pour hot cocoa-Cola mixture over dry ingredients. Stir gently until just combined, ensuring no dry pockets remain.
05 - Stir in eggs, buttermilk, baking soda, and vanilla extract until batter is smooth. Fold in marshmallows if using.
06 - Pour batter into prepared pan and spread evenly. Bake 30-35 minutes, or until a toothpick inserted in the center comes out clean.
07 - While cake bakes, melt butter in medium saucepan over medium heat. Stir in Coca-Cola and cocoa powder, bring to a boil while stirring constantly.
08 - Remove from heat and whisk in sifted powdered sugar gradually until smooth and spreadable. Stir in vanilla extract.
09 - Pour warm frosting evenly over hot cake. Use offset spatula or spoon to spread to edges. Frosting will slightly soak in as it sets.
10 - Allow cake to cool at room temperature before slicing. Serve warm or at room temperature for best texture.

# Extra Tips:

01 - Do not overmix batter for a soft texture. Mini marshmallows are optional and add richness. Store leftovers covered at room temperature up to 3 days or refrigerate for longer freshness.
