Ingredients
Makes one 9×13-inch sheet cake
Cake
- 2 cups (250g) all-purpose flour
- 2 cups (400g) granulated sugar
- 3/4 cup (75g) unsweetened cocoa powder
- 1 1/2 tsp baking powder
- 1 1/2 tsp baking soda
- 1 tsp fine salt
- 2 large eggs
- 1 cup whole milk
- 1/2 cup neutral oil (canola or vegetable)
- 2 tsp pure vanilla extract
- 1 cup boiling water
Whipped cream
- 1 1/2 cups heavy whipping cream
- 3 tbsp powdered sugar
- 1 tsp vanilla extract
Ganache
- 8 oz (225g) good-quality dark chocolate, chopped
- 3/4 cup hot cream
Step-by-step instructions
- Prep and oven
- Preheat oven to 350°F (175°C). Grease a 9×13-inch pan and line with parchment for easy removal.
- Make the batter
- Whisk together flour, sugar, cocoa, baking powder, baking soda, and salt in a large bowl.
- In a separate bowl, beat eggs, milk, oil, and vanilla until combined.
- Pour the wet ingredients into dry and stir until mostly smooth. Slowly add the boiling water and mix just until incorporated — the batter will be thin, and that’s perfect for a Moist Chocolate Sheet Cake with Whipped Cream and Ganache.
- Bake
- Pour batter into the prepared pan and bake 25–30 minutes, or until a toothpick in the center comes out with a few moist crumbs. Allow cake to cool completely in the pan.
- Whip the cream
- Chill a metal bowl and beaters for best results. Beat cream on medium-high speed until soft peaks form. Add powdered sugar and vanilla, then whip to medium peaks — spreadable but holds shape.
- Make the ganache
- Place chopped chocolate in a bowl. Heat cream until steaming (not boiling) and pour over chocolate. Let sit 1–2 minutes, then stir until glossy. If needed, microwave in 10-second bursts to smooth. For ganache technique tips and a pretty web finish, see this Spider Web Chocolate Ganache Cake Recipe for inspiration.
- Assemble
- Spread an even layer of whipped cream across cooled cake. Pour ganache over the whipped cream and gently spread; the ganache will set with a shiny finish. Chill 20–30 minutes to firm before slicing.
Tips for success
- Use room-temperature eggs for a smoother batter and better rise.
- Measure flour by spooning into the cup and leveling off to avoid a dense cake.
- Chill your bowl and beaters for whipped cream to reach peaks faster.
- If your ganache firms too quickly, warm gently to re-smooth. For savory sides that balance the cake at gatherings, consider a simple green salad or a hearty Chickpea Avocado Salad with Creamy Feta to offset sweetness.
- For portable slices, chill the cake to firm ganache before cutting with a hot knife (wipe clean between slices).
Possible variations
- Gluten-free: Substitute a 1:1 gluten-free flour blend and add 1/2 tsp xanthan gum if it’s not included in your blend. Bake times may vary slightly.
- Streusel topping: Sprinkle a cinnamon-sugar streusel over the whipped cream before adding ganache for extra crunch.
- Boozy syrup: Brush cooled cake with a simple syrup flavored with coffee liqueur (use a non-alcoholic coffee extract if preferred) for a deeper chocolate hit.
- Layered bars: Cut cake into rectangles and layer with extra whipped cream and berries for an elegant fall dessert tray. If you want to pair a richer savory or cheesy side, try serving small portions alongside Cheese Broth with Potatoes and Elote to create an adventurous menu mix.
Storage recommendations
- Room temperature: Keep slices covered for up to 24 hours; the whipped cream softens at room temp.
- Refrigerator: Store in an airtight container for 3–4 days. Bring to room temperature 20–30 minutes before serving for best texture.
- Freezing: Freeze uncut cake (well wrapped) for up to 1 month. Thaw overnight in the refrigerator and top with fresh whipped cream for best results.

FAQs
Q: Can I make the whipped cream ahead of time?
A: Yes — you can make whipped cream a few hours ahead and keep it covered in the refrigerator. For best texture, whip just to medium peaks and rewhip briefly before spreading if needed.
Q: How do I get a shiny ganache?
A: Use good-quality chocolate and heat the cream until just steaming. Pour cream over chocolate and let it sit for a minute before stirring slowly until glossy. Avoid overheating the mixture.
Q: Can I use low-fat milk in the cake?
A: Whole milk gives the richest texture, but 2% works if that’s what you have. The cake will still be moist due to the oil and boiling water.
Q: Is this cake freezer-friendly?
A: Yes — wrap the unfrosted cake tightly and freeze up to one month. Thaw in the refrigerator and frost with fresh whipped cream and ganache after thawing for the best texture.
