If you’re after a fail-safe chocolate dessert that’s always moist, rich, and utterly irresistible, this Moist Chocolate Chip Bundt Cake is a winner. It begins with a simple yellow cake mix but becomes extraordinary once you add instant chocolate pudding, sour cream, espresso powder (optional), and a full cup of chocolate chips. The result is a tender, bakery-style bundt cake that stays moist for days.
This cake is fantastic plain because the texture and chocolate flavor shine on their own. For a festive touch I topped mine with dark chocolate curls and fresh cranberries, but you can keep it simple with a dusting of powdered sugar or a light glaze. It’s a versatile recipe that works year-round — dress it up for holidays or serve it as an everyday treat.

No. It’s optional. Espresso powder simply enhances the chocolate notes without adding a coffee taste.

Moist Chocolate Chip Bundt Cake (With Cake Mix!)
Ingredients
- 1 box yellow cake mix
- 1 small 3.9 oz box instant chocolate pudding mix
- 1 teaspoon espresso powder (optional)
- 4 eggs whisked before adding
- ½ cup oil
- ½ cup water or hot coffee
- 8 oz sour cream
- 1 cup dark, milk, or semi-sweet chocolate chips tossed in 1 tablespoon flour so they don’t sink
- Butter for generously greasing the bundt pan
- Dark chocolate bar for shaving curls (optional)
Instructions
Mix the dry ingredients
-
In a large bowl, whisk together the yellow cake mix, instant chocolate pudding mix, and espresso powder if using.
Add the wet ingredients
-
Add the oil, water or hot coffee, sour cream, and the four whisked eggs. Mix until smooth, about 1–2 minutes.
Add the chocolate chips
-
Toss the chocolate chips with 1 tablespoon of flour, then gently fold them into the batter.
Prep your bundt pan
-
Generously butter the entire inside of the bundt pan — this helps the cake release cleanly.
Bake
-
Pour the batter into the prepared pan and bake at 350°F (175°C) for 45–50 minutes, or until a toothpick inserted comes out clean. My cake was perfect at 50 minutes.
Flip & cool
-
Let the cake cool in the pan for 10–15 minutes, then invert onto a plate and allow it to cool completely.
Decorate (or keep it simple!)
-
For a polished look shave a dark chocolate bar with a potato peeler to make curls and scatter them on top.
Alternatives
-
Dust with powdered sugar for a quick finish.
-
Drizzle a simple vanilla or chocolate glaze if you prefer a sweeter topping.
-
Or leave it plain — the cake is so moist it’s delicious on its own.
Make It Holiday-Ready: Dark Chocolate Ganache & Festive Garnishes
To give the cake a special holiday finish, make a simple ganache with about ¾ to 1 cup dark chocolate chips and ¼ cup heavy cream (add a little more cream if needed). Heat in short bursts, stirring until smooth and pourable. Pour the ganache slowly over the cake and let it drip naturally down the sides.
I finished mine by arranging fresh cranberries around the top edge for a bright pop of color, then shaved a dark chocolate bar with a potato peeler to create delicate curls and sprinkled them over the ganache just before serving. The combination is elegant but easy, and it makes the cake feel like a holiday centerpiece.
