This chocolate bundt cake is my go-to when I want something that looks special but doesn’t eat my entire afternoon. It’s built on a few pantry-friendly shortcuts—a boxed devil’s food mix and instant pudding—yet finishes with a glossy chocolate glaze and a sprinkle of toasted nuts so it feels utterly homemade and indulgent.

The crumb is dense and unbelievably moist thanks to the pudding and sour cream, and the melted butter and eggs give it a rich, tender structure. It bakes in a 10–12 cup bundt pan and comes out with a dramatic ring shape that’s perfect for birthdays, potlucks, or an elevated weeknight dessert.

Below you’ll find a clear ingredient list, step-by-step directions exactly as written from the recipe, and practical tips I use every time to avoid common pitfalls. Read through once, gather your tools, and you’ll have a reliably decadent cake on the table.

Gather These Ingredients

Ingredients

1 box devil’s food cake mix — the base flavor and structure; use devil’s food for a deep chocolate profile.
1 box instant chocolate pudding mix (3.4 ounce size) — adds moisture and a fudgy crumb.
2 cups sour cream — keeps the cake tender and moist; full-fat gives best texture.
5 eggs — provide lift and structure; room temperature eggs incorporate more evenly.
1 cup melted butter — adds richness and a tender crumb; melted simplifies mixing.
1 teaspoon almond extract — a little boost of flavor that complements chocolate.
1 cup semi-sweet chocolate chips — folded into the batter for pockets of melted chocolate.
3/4 cups semi-sweet chocolate chips — used for the glaze; melted with butter and corn syrup.
3 tablespoons butter — part of the glaze; makes it shiny and pourable.
1 tablespoon light corn syrup — gives the glaze a sheen and helps it set smoothly.
1/4 teaspoon vanilla extract — stirred into the glaze at the end for depth.
1/4 cup chopped toasted walnuts or pecans — adds crunch and contrast to the glossy glaze.
1/4 cup semi-sweet chocolate chips — reserved to sprinkle on top immediately after glazing.

Chocolate Bundt Cake Cooking Guide

Preheat the oven to 350°F (175°C). Grease a 10-12 cup bundt pan thoroughly (do not dust with flour).
Measure and separate the chocolate chips into three portions as listed: 1 cup for the batter, 3/4 cups for the glaze, and 1/4 cup for topping. Also set aside 1/4 cup chopped toasted walnuts or pecans for the topping.
In a large bowl combine 1 box devil’s food cake mix, 1 box instant chocolate pudding mix (3.4 ounce), 2 cups sour cream, 5 eggs, 1 cup melted butter, and 1 teaspoon almond extract.
Beat the mixture with a mixer on medium speed (or whisk vigorously by hand) until well blended and the batter is uniform. The batter will be thick.
Fold in 1 cup semi-sweet chocolate chips until evenly distributed.
Pour the batter into the prepared bundt pan and smooth the top with a spatula.
Bake in the preheated oven for 55 to 60 minutes, or until a toothpick or cake tester inserted near the center comes out clean or with a few moist crumbs.
Remove the pan from the oven and let the cake cool in the pan on a wire rack for 10 minutes.
Invert the cake onto the wire rack and remove the pan. Allow the cake to cool completely on the rack before glazing.
To make the glaze, set a heatproof bowl over (not touching) simmering water (double boiler). Add 3/4 cups semi-sweet chocolate chips, 3 tablespoons butter, and 1 tablespoon light corn syrup to the bowl.
Stir the mixture over the simmering water until the chocolate chips and butter are fully melted and the glaze is smooth. Remove from heat and stir in 1/4 teaspoon vanilla extract.
Place the cooled cake on a cake plate or serving platter. Pour the warm glaze over the top, allowing it to drip down the sides.
Immediately sprinkle the top with the reserved 1/4 cup semi-sweet chocolate chips and 1/4 cup chopped toasted walnuts or pecans.
Let the glaze set slightly before slicing and serving.

Why It Works Every Time

There are a few smart shortcuts here that combine to make a reliably moist, flavorful cake. The instant pudding mix doesn’t act like pudding in the finished cake; it pulls moisture into the crumb and gives a denser, fudgy texture that keeps the cake from drying out.

Sour cream brings fat and acidity, which tenderizes gluten and enhances overall richness. Melted butter disperses fat evenly throughout the batter and contributes to a glossy mouthfeel. The eggs provide structure so the cake holds its bundt shape without being cakey or crumbly.

The glaze uses a simple double boiler technique with corn syrup and butter. Corn syrup keeps the glaze glossy and slightly flexible so it sets without cracking, while the warmed glaze pours and hugs the cake, creating a polished finish that looks professional.

Texture-Safe Substitutions

If you need to swap ingredients, choose options that preserve moisture and fat so the texture stays close to the original:

For sour cream: full-fat Greek yogurt can be used as a one-to-one replacement; it will keep the cake moist but may be a touch tangier.
For melted butter in the batter: you can use neutral oil (like canola) for similar tenderness, but butter adds flavor—if you use oil, consider a tablespoon of butter flavor if you have it.
For semi-sweet chips: dark chocolate chips or coarsely chopped chocolate bars work fine; larger pieces create pockets of molten chocolate.
For nuts: toasted almonds or hazelnuts can replace walnuts/pecans. Toast them beforehand to boost flavor.

Prep & Cook Tools

10–12 cup bundt pan — greased thoroughly, no flouring.
Large mixing bowl and electric mixer (or whisk) — for even blending of a thick batter.
Measuring cups and spoons — accuracy matters for balance.
Spatula — to fold in chips and smooth the batter.
Wire rack — for cooling and glazing.
Heatproof bowl and saucepan for a double boiler (or a dedicated double boiler) — for a smooth glaze.
Cake plate or serving platter — for presentation and finishing.

Problems & Prevention

Here are the most common problems people encounter and exactly how I prevent them.

Cake sticks to the pan: Grease the pan thoroughly, paying attention to the crevices of the bundt. Use a butter or shortening with a pastry brush to get into the details. Do not flour the pan—the recipe warns against it.
Cake sinks in the middle: Make sure the oven temperature is accurate (use an oven thermometer). Avoid opening the oven door during the first 40–50 minutes of baking. Also, measure leavening-sensitive ingredients (the boxed mix) correctly.
Cake is dry: Don’t overbake. Start checking at 55 minutes with a toothpick inserted near the center; it should come out clean or with a few moist crumbs.
Glaze is grainy or seizes: Melt the glaze gently over simmering water and keep stirring. Make sure the bowl doesn’t touch the water and remove from heat as soon as it’s smooth before stirring in vanilla.
Glaze won’t set: Warm glaze will be fluid; allow the cake to cool completely before glazing so the glace sets properly. If it’s very warm where you live, pop the glazed cake in a cool spot (not the fridge) to help the glaze firm up slightly.

Variations by Season

Tiny tweaks make this cake feel seasonal without changing the method.

Winter: Add a pinch of instant espresso powder to the batter for a deeper chocolate profile. Garnish with candied orange peel for brightness.
Spring: Top with a light dusting of powdered sugar and a scattering of fresh raspberries for a fresher finish.
Summer: Serve slices with scoops of vanilla ice cream and a handful of toasted nuts on the side.
Autumn: Stir 1/2 teaspoon ground cinnamon into the glaze and swap pecans for walnuts to lean into cozy flavors.

Cook’s Commentary

I make this cake when I want something that looks dressed up but doesn’t require fussy technique. The batter is thick and forgiving; a spatula and a little elbow grease work fine if you don’t have a mixer. Give the cake ten minutes in the pan after baking — that short rest helps it release cleanly.

When pouring the glaze, I place the cake on a platter with a rim or a tray underneath to catch drips. Pour while the glaze is warm but not so hot it melts the nuts or chips you sprinkle on top. The immediate sprinkle of reserved chips and chopped nuts gives texture and contrast—don’t skip it.

Leftovers & Meal Prep

Store leftover cake tightly covered at room temperature for 2 days, or in the refrigerator for up to 5 days. Because the glaze contains butter and corn syrup, it keeps well chilled without becoming hard.

To freeze slices: wrap individual slices in plastic wrap, then place in a freezer bag for up to 2 months. Thaw in the fridge overnight and bring to room temperature before serving. If you expect to freeze, you can freeze the unglazed cake and add the glaze after thawing for the best finish.

Reader Q&A

Q: Can I use a different cake mix?
A: Yes—devil’s food gives the deepest chocolate flavor, but a regular chocolate cake mix will work. The texture may vary slightly depending on the mix formulation.

Q: Do I have to use almond extract?
A: No. Almond extract is optional but it adds a subtle boost to the chocolate. If you skip it, you can replace with an equal amount of vanilla extract.

Q: My bundt pan is smaller—what then?
A: The recipe specifies a 10–12 cup pan. If your pan is smaller, reduce the batter proportionally or use two smaller pans and adjust baking time—check for doneness earlier.

Q: Can I make this ahead?
A: Yes. Bake the cake a day ahead, cool completely, then glaze just before serving for the best glossy finish. Alternatively, store glazed cake in the fridge and bring to room temperature before serving.

Hungry for More?

If you loved the texture and richness of this cake, try switching up the glaze or the nut topping next time. The same structure works well with mocha glaze, salted caramel drizzle, or even a simple dusting of powdered sugar for a lighter look. Keep a box of devil’s food mix and pudding in your pantry—you’ll be surprised how often this combination will save the day and earn compliments.

Make it once and you’ll have a new reliable recipe for celebrations and impromptu guests. Happy baking—slice generously and enjoy every fudgy bite.
