This Easy Chocolate Pumpkin Cake Recipe combines a boxed devil’s food or chocolate cake mix with pure pumpkin purée, eggs, oil, water, and pumpkin pie spice. The batter takes only 10 to 15 minutes to prepare, then bakes in a 9-by-13-inch pan at 350°F (175°C) for 30 to 35 minutes, making it a simple dessert for fall gatherings, potlucks, and weeknight treats.
The finished cake is soft, moist, deeply chocolatey, and gently spiced without tasting overly pumpkin-heavy. Optional semisweet chocolate chips add little pockets of melted chocolate, while a quick vanilla glaze gives each slice a pretty finish.

This cake is made for bakers who want a homemade-tasting dessert without measuring flour, cocoa powder, granulated sugar, or a long list of extra ingredients. A boxed chocolate cake mix provides a dependable base, while pumpkin purée contributes moisture and a soft, tender crumb.
The flavor lands between classic chocolate cake and warmly spiced pumpkin dessert. Pumpkin pie spice adds a subtle note of cinnamon and autumn spice, but the chocolate remains the main attraction.
It is also a generous pan dessert. One 9-by-13-inch cake yields 12 to 16 servings, so it works beautifully for school events, family dinners, holiday buffets, and casual entertaining.

Ingredients You’ll Need
The ingredient list is short, practical, and easy to find. Gather everything before mixing so the batter can go straight into the pan once it is combined.
- Chocolate cake mix: Use one box of devil’s food or chocolate cake mix weighing about 15.25 ounces.
- Pure pumpkin purée: Choose a 15-ounce can labeled plain pumpkin purée. Do not substitute pumpkin pie filling, which already contains sugar and spices.
- Eggs, oil, and water: Three large eggs, one-third cup neutral vegetable oil, and one-half cup water create a soft, conventional cake texture.
- Pumpkin pie spice: One teaspoon gives the cake a gentle seasonal aroma without overpowering the chocolate.
- Chocolate chips: One cup of semisweet chips is optional, but highly recommended for a more pronounced chocolate flavor.
- Glaze ingredients: Powdered sugar, milk or cream, and vanilla extract make a quick, pourable topping.

How to Make It Step-by-Step
Step 1: Begin by heating the oven to 350°F (175°C). Grease a 9-by-13-inch baking pan thoroughly, or line it with parchment paper so the cooled cake can be lifted out more easily.
Step 2: Add the chocolate cake mix, plain pumpkin purée, eggs, vegetable oil, water, and pumpkin pie spice to a large bowl. Whisk until the ingredients are just combined and the batter looks smooth, stopping as soon as you no longer see dry cake mix.
Step 3: Fold in one cup of semisweet chocolate chips if you are using them. Gentle folding helps keep the batter light and prevents the chips from collecting in one area.
Step 4: Transfer the batter to the prepared pan and spread it evenly from corner to corner. A flexible spatula makes it easier to level the thick batter without pressing it down too firmly.
Step 5: Bake the cake for 30 to 35 minutes. Begin checking toward the end of that range: the center should spring back lightly, and a toothpick inserted near the center should show a few moist crumbs rather than wet batter.
Step 6: Set the pan on a cooling rack and wait at least 30 minutes, preferably until the cake is completely cool, before adding the glaze. This resting time helps the crumb settle and makes cleaner slices possible.
Step 7: Whisk one and one-half cups powdered sugar with two to three tablespoons milk or cream and one-half teaspoon vanilla extract. Drizzle the smooth glaze over the cooled cake, allowing it to fall naturally across the surface before serving.
Pro Tips for the Best Texture
Read the pumpkin label carefully. Plain pumpkin purée is the correct choice, while pumpkin pie filling contains added sugar and spices that can change the cake’s sweetness, flavor, and texture.
Most canned pumpkin is ready to use, but inspect it before adding it to the bowl. If it appears unusually watery, drain it briefly so the finished cake does not become looser than intended.
Do not overmix the batter. Whisking only until smooth keeps the cake tender, while excessive mixing can produce a heavier crumb.
Chocolate chips are optional, but they make the cake taste especially rich and chocolate-forward. Semisweet chips balance the pumpkin’s natural earthiness without making the dessert excessively sweet.
For a different topping, replace the vanilla glaze with a thin chocolate ganache. A simple dusting of powdered sugar also works when you prefer a less decorated finish.

Serving Ideas and Seasonal Presentation
Serve the cake in neat squares with the vanilla glaze visible across the top. For a cozy finish, add a small pinch of extra pumpkin pie spice over the glaze immediately after drizzling, using only a light touch.
This dessert is satisfying at room temperature, but it can also be served slightly chilled for a firmer, fudgier bite. Pair each serving with coffee, black tea, hot chocolate, or a scoop of vanilla ice cream.
For a fall celebration, arrange the slices on a platter with a few small pumpkins or autumn leaves nearby. If children are helping decorate, keep the topping simple and let them scatter the chocolate chips over the glaze.
Storage and Make-Ahead Advice
Let the cake cool completely before covering it. Keeping it covered protects the moist crumb and prevents the glaze from drying out.
For a short period, store the covered cake at room temperature in a cool area. For longer storage, refrigerate it in an airtight container and allow slices to sit briefly before serving so the texture softens.
The cake is a convenient make-ahead dessert because it can be baked, cooled, glazed, and portioned before guests arrive. Use a sharp knife and wipe the blade between cuts for tidy squares.

Easy Chocolate Pumpkin Cake
Ingredients
Method
- Heat the oven to 350°F (175°C). Grease a 9-by-13-inch baking pan or line it with parchment paper, leaving a little overhang for easy lifting.
- Add the cake mix, pumpkin purée, eggs, vegetable oil, water, and pumpkin pie spice to a large mixing bowl. Whisk just until the batter is smooth and combined; avoid prolonged mixing.
- Fold in the semisweet chocolate chips if using them. Use a spatula and make only a few gentle turns so the chips remain evenly distributed.
- Spread the batter evenly in the prepared pan. Smooth the surface with a spatula so the cake bakes to an even thickness.
- Bake for 30 to 35 minutes, checking near the end of the baking time. The center should spring back lightly, and a toothpick inserted near the center should come out with a few moist crumbs.
- Place the pan on a cooling rack and let the cake cool completely for at least 30 minutes before glazing or slicing. The pumpkin keeps the crumb moist, so cutting too soon can make the texture seem gummy.
- For the glaze, whisk the powdered sugar, milk or cream, and vanilla extract together until smooth. Drizzle it over the cooled cake, let it set briefly, and cut into 12 to 16 servings.
Notes
