Ingredients You’ll Need 🥄
Before diving into the recipe, let’s look at the essential ingredients that create this masterpiece.
For the Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1/4 teaspoon salt
- 4 tablespoons unsweetened cocoa powder
- 1 cup (2 sticks) unsalted butter
- 1 cup boiling water (or hot coffee for a mocha twist)
- 1/2 cup buttermilk (or milk + vinegar substitute)
- 2 large eggs
- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
For the Fudgy Frosting:
- 14 tablespoons (1 3/4 sticks) butter
- 4 tablespoons cocoa powder
- 6 tablespoons whole milk
- 1 teaspoon vanilla extract
- 3 3/4 cups powdered sugar
- 1/2 cup chopped pecans or walnuts (optional)
Step-by-Step Instructions 🧑🍳
1. Preheat & Prep
- Heat oven to 350°F (175°C).
- Grease and flour a 13×18-inch sheet pan (also called a half-sheet pan). Lining with parchment makes cleanup easier.
2. Mix Dry Ingredients
In a large mixing bowl, whisk together:
- Flour, sugar, and salt.
Set aside—this will be your dry base.
3. Make the Chocolate Base
- In a saucepan, melt butter.
- Stir in cocoa powder.
- Add boiling water, whisk until smooth, and bring to a gentle boil.
- Pour this hot chocolate mixture directly into the dry ingredients. Mix well.
4. Blend Wet Ingredients
- In a separate bowl, whisk together buttermilk, eggs, baking soda, and vanilla.
- Stir this mixture into the chocolate batter. Blend just until smooth—don’t overmix.
5. Bake
- Pour the batter into the prepared pan.
- Smooth the top with a spatula.
- Bake for 18–22 minutes, until a toothpick inserted comes out clean.
Making the Signature Warm Frosting ✨
What makes this cake legendary is the frosting poured while the cake is still warm. It seeps into the surface, creating a fudgy, silky finish.
- In a saucepan, melt butter.
- Stir in cocoa powder and milk. Bring to a gentle simmer.
- Remove from heat and whisk in vanilla + powdered sugar until glossy.
- Stir in pecans if using.
- Immediately pour over the hot cake and spread evenly.
⚡ Tip: Work quickly! The frosting sets fast.
Tips for Success ✅
- Use quality cocoa powder – it makes all the difference in flavor.
- Don’t overbake – a slightly underdone cake is moister than a dry one.
- Frost while hot – this ensures the fudgy signature texture.
- Customize the toppings – nuts, sprinkles, or even a swirl of peanut butter.
- Let it rest – the cake tastes even better the next day.
Fun Flavor Variations 🍰
- Mocha Sheet Cake – Swap boiling water with hot coffee + add espresso powder.
- Mexican Chocolate – Add cinnamon + a pinch of cayenne.
- Nut-Free Delight – Skip nuts, top with chocolate chips or toasted coconut.
- Holiday Twist – Sprinkle crushed peppermint or use white chocolate drizzle.
- Peanut Butter Lovers – Swirl in peanut butter chips or drizzle PB over frosting.
