Ingredients for hershey's chocolate cake recipe with boiling water
Nine pantry staples, one bowl, and thirty minutes to a bakery-style chocolate cake.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 2 cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Cold, cut into cubes |
| Hershey's Cocoa Powder 🍫 | ½ cup | Natural or Dutch-processed |
| Baking Soda 🧪 | 1 tsp | Pure, not baking powder |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🥄 | 1 tbsp | Pure, not imitation |
| Boiling Water 💧 | 1 cup | Freshly boiled, not tap |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Buttermilk 🥛 | ½ cup | Fresh, not powdered |
| Powdered Sugar 🍚 | ½ cup | For optional glaze |
| Heavy Whipping Cream 🥛 | ½ cup | Cold, for optional glaze |
The Hershey's cocoa powder is non-negotiable here—this recipe demands that classic chocolate flavor. Hershey's Special Dark or Hershey's Natural Cocoa both work, but avoid Dutch-processed if you want that authentic Hershey's taste. For the butter, Land O'Lakes unsalted or Plugrá are my go-tos; they hold their shape perfectly when cut into cubes. The buttermilk adds moisture without altering the cake's density, so don’t substitute with plant-based alternatives—they can make the texture gummy. If you’re out, mix 1 tbsp lemon juice or vinegar with 0.5 cup milk and let it sit for 5 minutes.
Boiling water is the game-changer, but don’t stress about precision. Tap water with chlorine can slightly alter the flavor, so if your water tastes metallic, use filtered or bottled instead. The eggs should be at room temperature—this ensures even incorporation without lumps. For the vanilla, Nielsen-Massey or McCormick Pure Vanilla extract delivers the most authentic aroma. The powdered sugar for the glaze? Domino or C&H brands sift smoothly and avoid clumping. If you’re avoiding dairy, the buttermilk can be replaced with 0.5 cup plain yogurt plus 0.25 cup milk, though the texture will be slightly denser.
This cake keeps beautifully for 3 days at room temperature, wrapped tightly in plastic. For longer storage, slice and freeze portions for up to 3 months—they thaw in 10 minutes at room temperature. The glaze, if made, should be piped or drizzled immediately after baking to prevent the top from drying. Store leftovers in an airtight container with parchment between layers to maintain moisture. Reheat slices in the microwave for 10-15 seconds to restore that bakery-warm feel.

Step-by-step instructions for fudgy boil-and-bake chocolate cake
This method delivers rich, moist layers with a crackly top in under 30 minutes—no mixer required.
Prepare the Boiling Water Batter
In a large mixing bowl, whisk together the 2 cups granulated sugar, 0.5 cup Hershey's cocoa powder, 1 tsp baking soda, and 0.5 tsp salt until completely dissolved. The mixture should be smooth with no lumps—this ensures even texture throughout the cake.
Add the 1 cup boiling water next, stirring vigorously for 2 minutes until the mixture cools slightly and thickens. You'll notice it transform from a thin liquid into a slightly syrupy consistency—this is crucial for the cake's fudgy texture. Let it sit for 1 minute to allow the baking soda to fully activate.
Incorporate Wet Ingredients
Cut the 1 cup cold unsalted butter into ½-inch cubes and add to the warm mixture. Whisk continuously until the butter melts completely and the batter becomes smooth and glossy. This step creates the cake's signature moisture—don't rush it, as unmelted butter creates dense pockets.
Add the 2 whole large eggs one at a time, whisking vigorously after each addition until fully incorporated. Stir in the 1 tbsp vanilla extract and 0.5 cup buttermilk, mixing until just combined. The batter should be thick but pourable—if it's too stiff, add 1 tablespoon boiling water to adjust.
Fold in the Flour
Gently fold in the 2 cups all-purpose flour using a spatula, mixing just until no dry streaks remain. Overmixing develops gluten, which can make the cake tough. The batter should be smooth and slightly shiny, with a consistency similar to thick pancake batter.
Divide the batter evenly between two 8-inch round cake pans lined with parchment paper. Tap the pans gently on the counter to remove air bubbles—this prevents dome-shaped cakes. Bake at 350°F (175°C) for 25-30 minutes until a toothpick inserted in the center comes out with moist crumbs (not wet batter).
Prepare the Cream Cheese Glaze (Optional)
While the cakes cool for 10 minutes, beat the 0.5 cup heavy whipping cream to soft peaks in a chilled bowl. Gradually add the 0.5 cup powdered sugar, beating until stiff peaks form. This glaze adds a light, cloud-like finish that contrasts beautifully with the dense cake layers.
Spread the glaze evenly between the two cooled cake layers, pressing gently to ensure full coverage. Chill for 30 minutes before slicing—this allows the glaze to set properly and prevents a messy crumbly texture. The final result should be rich, fudgy layers with a velvety glaze that melts at the first bite.
Pro Tips For Making Hershey'S Chocolate Cake Recipe With Boiling Water
- Boil Water First: The recipe calls for boiling water, but I used to just pour cold water into the hot butter mixture—big mistake. Boil the water first, then pour it into the butter while it’s still bubbling. This keeps the butter from seizing up and gives you that signature fudgy texture.
- Sift the Cocoa: Hershey’s cocoa powder is dense, and clumps ruin the cake’s lightness. Sift it directly into your dry ingredients before adding the wet mix. I learned this after my first cake turned out dense and heavy—now it’s fluffy every time.
- Don’t Overmix the Batter: Once you add the flour, mix just until combined. Overmixing develops gluten and makes the cake tough. I used to beat it like I was trying to win a baking contest, and the result was a brick. Two minutes max with a spatula—gentle is better.
- Use Room-Temp Butter: Cold butter creates pockets of steam that can make the cake sink in the middle. Let it sit out for 30 minutes before measuring. I skipped this once and ended up with a sunken center—now I always check the butter first.
Dietary considerations for this hershey's chocolate cake recipe with boiling water
Gluten-Free Adaptation
For a gluten-free version, replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend like Bob’s Red Mill or King Arthur. Add 1 tsp xanthan gum to help bind the cake—this is crucial for maintaining structure.
The boiling water method still works, but reduce the baking time to 22-25 minutes since gluten-free cakes can dry out faster. I’ve tested this with King Arthur Measure for Measure and it holds together beautifully. 🌾
Dairy-Free Options
Swap the 1 cup butter for 1 cup dairy-free butter like Earth Balance or Miyoko’s, and replace the 0.5 cup buttermilk with 0.5 cup unsweetened almond milk + 1 tbsp lemon juice.
For the glaze, use coconut whipped cream (chilled overnight) and powdered sugar. The texture stays moist but slightly denser—expect a richer, fudgier result. Always use room-temperature dairy substitutes to avoid lumps. 🥛
Lower-Sugar Version
Reduce the 2 cups granulated sugar to 1.5 cups and replace the remaining 0.5 cup with monk fruit sweetener (like Lakanto). Adjust the boiling water to 0.75 cup to compensate for reduced sugar content.
The cake will still be moist but less sweet—perfect for those watching sugar intake. I’ve also added 1 tsp vanilla bean paste to enhance flavor depth without extra sugar. 🍚
Vegan Substitutes
For a fully vegan cake, use 1 cup coconut oil (solid) instead of butter, and replace eggs with 2 tbsp ground flaxseed + 6 tbsp water (let sit for 5 minutes to thicken). Substitute buttermilk with 0.5 cup unsweetened soy milk + 1 tbsp apple cider vinegar.
The boiling water method works, but bake at 325°F for 30-35 minutes—vegan cakes need extra time to set. 🥚
Allergen-Friendly Tips
If nut allergies are a concern, use sunflower seed butter instead of nut-based substitutes. For egg allergies, aquafaba (chickpea brine) works as a 1:1 egg replacer—whisk 2 tbsp aquafaba until frothy before adding.
Always check labels on dairy-free substitutes for hidden allergens like soy or gluten. I keep a small container of Nutiva sunflower seed butter in my pantry for emergencies. 💡

Frequently asked questions
Why does this recipe use boiling water instead of regular water?
The boiling water instantly activates the baking soda, creating a chemical reaction that develops the cake's structure while keeping it incredibly moist. This method eliminates the need for long mixing times and produces a fudgy texture without dry crumbs. The heat also helps dissolve the sugar and cocoa more thoroughly for even flavor distribution.
Can I make this cake in a single layer instead of two?
Yes! Use a 9-inch round pan or 8-inch square pan and reduce the baking time to 20-25 minutes. The boiling water method works perfectly for single-layer cakes too—just check for doneness with a toothpick. For a taller cake, bake in a 6-inch round pan for 30-35 minutes at 350°F (175°C).
What if my batter is too thick or too thin?
If the batter is too thick, add 1 tablespoon boiling water at a time until it reaches a pourable consistency. If it's too thin, whisk in 1 tablespoon extra flour until smooth. The ideal texture should be like thick pancake batter—slightly syrupy but still able to flow gently. Overmixing can develop gluten, so stir just until combined.
How do I store leftovers to keep them moist?
Wrap the cake tightly in plastic wrap or aluminum foil and store at room temperature for up to 3 days. For longer storage, slice and freeze portions for 3 months. Thaw at room temperature for 10 minutes before serving. To refresh dry slices, place them in a 350°F (175°C) oven for 5-10 seconds—just enough to warm through without overcooking.
Can I substitute Hershey's cocoa powder with another brand?
For the best results, stick with Hershey's Natural Cocoa or Hershey's Special Dark—these deliver the classic Hershey's flavor. Other brands like Ghirardelli or Dutch-processed cocoa can work, but the taste will differ slightly. If substituting, reduce the baking soda to ½ tsp since Dutch-processed cocoa is less alkaline. Always sift the cocoa powder for even distribution.
