Ingredients

• For the Cake
• 2 cups all-purpose flour
• 1 ¾ cups granulated sugar
• ¾ cup unsweetened cocoa powder (natural or Dutch-processed)
• 2 teaspoons baking soda
• 1 teaspoon baking powder
• 1 teaspoon salt
• 2 large eggs, at room temperature
• ½ cup vegetable oil
• ¼ cup unsalted butter, melted and cooled slightly
• 1 cup buttermilk, at room temperature (or 1 cup milk + 1 tablespoon lemon juice or white vinegar, let sit 5 mins)
• 1 cup hot brewed coffee (or hot water)
• 2 teaspoons vanilla extract
• For the Frosting
• ½ cup (1 stick) unsalted butter, softened
• ¾ cup unsweetened cocoa powder
• 4 cups powdered sugar, sifted
• ½ teaspoon salt
• ¼ cup milk or heavy cream (plus more if needed)
• 1 teaspoon vanilla extract

Directions

1. Prep the Pan and Oven Preheat your oven to 350°F (175°C). Grease a 9x13-inch rectangular baking pan with butter or non-stick spray. For easier removal (though this cake is often served in the pan!), you can line the bottom with parchment paper, leaving an overhang on the sides to create a "sling." This prevents sticking and makes serving a breeze if you decide to lift it out.
2. Mix Dry Ingredients In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. Whisking ensures all the leavening agents and cocoa are evenly distributed, preventing lumps and ensuring a consistent rise and flavor throughout the cake.
3. Mix Wet Ingredients In a separate medium bowl, whisk together the eggs, vegetable oil, melted butter, buttermilk, and vanilla extract until well combined and smooth. This order helps prevent curdling and ensures a perfectly emulsified mixture for a tender cake.
4. Make It Chocolatey (The “Bloom” Moment) Pour the wet ingredient mixture into the dry ingredients and mix on low speed with an electric mixer, or by hand with a whisk, until just combined. The batter will be thick. Carefully pour the hot brewed coffee (or hot water) into the batter. Mix until smooth. The hot liquid helps "bloom" the cocoa powder, intensifying its chocolate flavor and creating that signature fudgy texture. The batter will be quite thin – don't worry, that's exactly how it should be!
5. Bake Pour the thin batter evenly into your prepared 9x13-inch pan. Bake for 30-35 minutes, or until the edges are set, the center is slightly springy when gently pressed, and a toothpick inserted into the center comes out with a few moist crumbs attached (not wet batter!). Overbaking will lead to a dry cake, so keep an eye on it!
6. Cool (The Non-Negotiable Part) Allow the cake to cool completely in the pan on a wire rack. This is a crucial step! Attempting to frost a warm cake will cause the frosting to melt and turn into a runny mess. Patience is key for perfect fudginess. This usually takes about 1 hour.
7. Make Frosting While the cake cools, prepare your frosting. In a large bowl, beat the softened butter with an electric mixer until creamy. Gradually add the cocoa powder, powdered sugar, and salt, mixing on low speed until combined. Slowly add the milk or cream, and vanilla extract. Increase speed to medium-high and beat until light, fluffy, and spreadable like soft peanut butter. If the frosting is too thick, add more milk a teaspoon at a time. If it's too thin, add more powdered sugar a tablespoon at a time.
8. Frost and Serve in the Pan Once the cake is completely cool, spread the fudgy frosting evenly over the top. You can use an offset spatula to create a smooth, inviting surface. For an optional easy finish, consider a sprinkle of mini chocolate chips, some shaved chocolate, or even a simple piped border around the edges. Slice and serve your delicious Jersey Cake directly from the pan!
