Directions
- Preheat your oven to 350°F (175°C). Grease and flour a 13×18 inch baking sheet.
- In a large bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix on medium speed until well combined.
- Carefully stir in the boiling water until the batter is smooth (the batter will be thin).
- Pour the batter into the prepared baking sheet. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
- Allow the cake to cool in the pan on a wire rack for about 15 minutes before removing it to cool completely.
- In a small saucepan, heat the heavy cream until just simmering. Remove from heat and add the chopped semi-sweet chocolate. Stir until melted and smooth.
- Once the cake is completely cooled, spread a layer of whipped cream on top and drizzle the ganache over it. Slice and serve!
Tips & Variations
- Ingredient substitutions: For a lighter version, you can substitute the all-purpose flour with a gluten-free blend. Swap the granulated sugar with coconut sugar or a sugar alternative to lower calories if desired.
- Optional variations: Try adding a layer of fresh fruits such as strawberries or raspberries on top of the whipped cream for added flavor. You can also sprinkle some chopped nuts for an extra crunch.
- Storage or reheating tips: Store leftover cake in an airtight container in the refrigerator for up to 3 days. To serve again, simply let it sit at room temperature for a few minutes before enjoying.
