- Step 9: Stir in the cocoa powder until smooth.

Tips & Variations
- Use strong brewed coffee instead of boiling water to deepen the chocolate flavor.
- To make cupcakes, fill liners two-thirds full and bake for 20 minutes at the same temperature.
- Ensure cakes are fully cooled before frosting to prevent melting the icing.
- For a dairy-free version, substitute milk and butter with plant-based alternatives.
Storage
Store the cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Let refrigerated or frozen cake come to room temperature before serving. Reheat briefly in the microwave if preferred warm.

FAQs
Can I use regular cocoa powder instead of Hershey’s?
Yes, you can substitute with any unsweetened cocoa powder, but the flavor may vary slightly. Hershey’s cocoa has a distinct taste that complements this recipe well.
Why is the batter so thin after adding boiling water?
The boiling water thins the batter and helps intensify the cocoa flavor. This is normal and results in a moist, tender cake once baked.

Cake Ingredients
- 2 cups Sugar
- 1 3/4 cups All-purpose flour
- 3/4 cup Hershey’s Cocoa
- 1 1/2 tsp Baking powder
- 1 1/2 tsp Baking soda
- 1 tsp Salt
- 2 Eggs
- 1 cup Milk
- 1/2 cup Vegetable oil
- 2 tsp Vanilla extract
- 1 cup Boiling water
Icing Ingredients
- 1/2 cup Butter
- 1 2/3 cups Hershey’s Cocoa
- 2 cups Powdered sugar
- 1/3 cup Milk
- 1 tsp Vanilla extract
Instructions
- Preheat oven: Set your oven to 350°F (175°C) to prepare for baking the cakes.
- Prepare pans: Grease and flour two 9-inch round baking pans to prevent the cake from sticking.
- Mix dry ingredients: In a large bowl, combine sugar, all-purpose flour, cocoa powder, baking powder, baking soda, and salt ensuring they are well blended.
- Add wet ingredients: Add eggs, milk, vegetable oil, and vanilla extract to the dry mixture. Beat the mixture at medium speed for 2 minutes until smooth and well incorporated.
- Incorporate boiling water: Carefully stir in the boiling water. The batter will be thin, which is expected for a moist cake texture.
- Pour and bake: Divide the batter evenly into the prepared pans and bake in the preheated oven for 30-35 minutes. Check doneness by inserting a wooden pick into the center; it should come out clean.
- Cool the cakes: Let the cakes cool in the pans for 10 minutes. Then, remove them and place them on wire racks to cool completely before frosting.
- Make the icing: Melt the butter in a bowl and stir in the cocoa powder until smooth.
- Blend icing ingredients: Alternately add the powdered sugar and milk to the cocoa-butter mixture, beating continuously until the icing reaches a spreadable consistency. Adjust with more milk if necessary.
- Finish icing: Stir in the vanilla extract for flavor.
- Assemble cake: Once cakes are completely cooled, spread the icing evenly between layers and over the top and sides for a luscious finish.
Notes
- For cupcakes, bake the batter for about 20 minutes instead of 30-35 minutes.
- Ensure the cakes are fully cooled before icing to prevent melting the frosting.
- The batter will be very thin due to boiling water—this is normal and results in a moist cake.
- You can substitute vegetable oil with an equal amount of melted butter for a richer flavor.
- Use high-quality cocoa powder like Hershey’s for the best chocolate taste.
