Ingredients

For the Chocolate Sheet Cake

All-purpose flour (1¾ cups)
Granulated sugar (2 cups)
Unsweetened cocoa powder (¾ cup)
Baking soda (2 teaspoons)
Baking powder (1 teaspoon)
Kosher salt (1 teaspoon)
Buttermilk (1 cup, room temperature)
Vegetable oil (½ cup)
Eggs (2 large, room temperature)
Vanilla extract (2 teaspoons)
Freshly brewed hot coffee (1 cup)

For the Vanilla Ermine Filling

Whole milk (1 cup)
All-purpose flour (5 tablespoons)
Unsalted butter (1 cup, room temperature)
Granulated sugar (1 cup)
Vanilla extract (1 teaspoon)

For the Chocolate Ermine Frosting

All-purpose flour (5 tablespoons)
Unsalted butter (1 cup, room temperature)
Granulated sugar (1 cup)
Dutch-process cocoa powder (½ cup)

Ingredient Tips

The hot coffee enhances the chocolate flavor without making the cake taste like coffee. If preferred, substitute hot water.
Room temperature ingredients ensure smooth mixing. Cold buttermilk or eggs can cause the batter to curdle.
Dutch-process cocoa powder gives the frosting a deeper color and richer taste, but natural cocoa works in a pinch.

Step-by-Step Instructions

Bake the Chocolate Sheet Cake

Preheat your oven to 350°F. Grease a 10×15 inch jelly roll sheet pan with nonstick spray.
In a stand mixer bowl, combine flour, sugar, cocoa powder, baking soda, baking powder, and salt. Mix briefly to combine.
In a separate bowl, whisk buttermilk, oil, eggs, and vanilla until smooth.
With the mixer on low, slowly pour the wet mixture into the dry ingredients. Mix until just combined.
Pour in the hot coffee and mix on low, scraping the bottom to catch any dry pockets.
Transfer the batter to the prepared pan and bake for 28–30 minutes, until a toothpick comes out mostly clean.
Cool the cake completely in the pan, then chill in the freezer or refrigerator until firm.

Make the Vanilla Ermine Filling

Whisk milk and flour in a saucepan over medium heat. Cook, whisking constantly, until thickened into a paste (3–5 minutes).
Cool the paste completely to room temperature.
Beat butter and sugar in a stand mixer until light and fluffy (2–3 minutes).
Add the cooled milk paste and beat until fluffy again.
Switch to the whisk attachment, add vanilla, and whip on high for 7–8 minutes until smooth.

Make the Chocolate Ermine Frosting

Repeat the milk and flour paste process as done for the vanilla filling. Cool completely.
Beat butter, sugar, and cocoa powder until light and fluffy (2–3 minutes).
Add the cooled milk paste and beat until fluffy.
Switch to the whisk attachment, add vanilla, and whip on high for 8–10 minutes until creamy.

Assemble the Cake

Slice the chilled cake in half lengthwise to create two equal rectangles.
Place one rectangle on a serving platter and spread the vanilla filling evenly over the top.
Place the second cake layer on top, pressing gently.
Spread the chocolate frosting over the top in rustic swirls.
Refrigerate for at least 1 hour before slicing.

Healthier Alternatives

Serving Suggestions

Pair with a cold glass of milk for classic nostalgia.
Serve with fresh berries to balance the richness.
Dust with powdered sugar for an elegant touch.

Common Mistakes to Avoid

Overbaking the cake will dry it out. Remove it when the toothpick has just a few crumbs.
Adding warm milk paste to the butter mixture can melt the butter. Always cool it completely.
Rushing the chilling step makes the cake harder to slice. Be patient for clean layers.

Storage Tips

Refrigerate for up to 5 days in an airtight container.
Freeze unfrosted cake layers for up to 3 months. Thaw before assembling.
Bring slices to room temperature before serving for the best texture.
