Double Chocolate Bundt Cake

Step 5: Add the Sour Cream

Add the sour cream and mix until just combined.

Sour cream adds moisture and a subtle tang that balances the richness of the chocolate. It also helps create the soft, tender texture that makes Bundt cakes so satisfying.

Don’t overmix once the sour cream has been incorporated.

Step 6: Combine the Dry and Wet Ingredients

Add the dry ingredients to the butter mixture in two or three additions, alternating with the hot coffee.

Begin with some of the dry mixture, then add part of the coffee. Continue alternating until everything is incorporated.

Mix gently just until the batter is smooth.

The batter will be fairly thin compared with some traditional cake batters. This is completely normal. The hot coffee helps bloom the cocoa powder and creates a particularly rich chocolate flavor.

Step 7: Fold in the Chocolate Chips

Add the semi-sweet chocolate chips and gently fold them into the batter with a spatula.

Try to distribute them evenly without overmixing the batter.

For an especially chocolatey cake, you can reserve a small handful of chocolate chips to sprinkle over the batter after it has been poured into the pan.

Step 8: Fill the Bundt Pan

Pour the batter evenly into the prepared Bundt pan.

Gently tap the pan against the countertop once or twice to release any large air pockets.

Use a spatula to smooth the top if necessary.

Do not fill the pan all the way to the top. Leave enough room for the cake to rise during baking.

Step 9: Bake the Cake

Place the Bundt pan in the center of the preheated oven.

Bake for approximately 50 to 60 minutes, or until a wooden skewer or cake tester inserted into the thickest part of the cake comes out with a few moist crumbs attached.

Try not to overbake the cake. A few moist crumbs are ideal; a completely dry tester can mean the cake has already gone a little too far.

Because ovens vary, begin checking the cake around the 50-minute mark.

Step 10: Let the Cake Cool

Remove the cake from the oven and place the pan on a wire rack.

Allow it to cool in the pan for approximately 15 to 20 minutes.

Then carefully invert the cake onto the rack.

If you prepared the Bundt pan thoroughly, the cake should release cleanly.

Allow it to cool completely before adding the glaze. Pouring glaze over a very hot cake can cause it to melt and run off too quickly.

How to Make the Chocolate Glaze

While the cake cools, prepare the glaze.

Place the chocolate chips, heavy cream, and butter in a heatproof bowl.

Warm the mixture gently, either in short microwave intervals or over a saucepan of barely simmering water.

Stir until the chocolate is completely melted and the mixture becomes smooth and glossy.

Add the vanilla extract and stir once more.

Let the glaze sit for several minutes so it thickens slightly but remains easy to pour.

Step 11: Glaze the Cake

Once the cake has completely cooled, place it on a serving plate or cake stand.

Slowly drizzle the chocolate glaze over the top, allowing it to naturally flow down the ridges of the Bundt cake.

For a more dramatic presentation, let some areas have a heavier layer of glaze while allowing other sections to remain lightly covered.

If desired, sprinkle chocolate shavings or mini chocolate chips over the glaze before it sets.

Step 12: Slice and Serve

Allow the glaze to set for several minutes before slicing.

Use a sharp knife to cut the cake into generous slices.

Serve it on its own, or add a scoop of vanilla ice cream, a dollop of lightly whipped cream, or a handful of fresh berries.

The contrast between the rich chocolate cake and something cool and creamy makes every bite even more enjoyable.

Tips for the Best Double Chocolate Bundt Cake

Grease the Pan Thoroughly

Don’t underestimate this step. Bundt pans have plenty of decorative grooves where cake can stick. Use softened butter or baking spray and carefully coat the entire interior.

Use Room-Temperature Ingredients

Room-temperature eggs, butter, and sour cream blend more smoothly and help create a consistent batter.

Don’t Overmix

Once the flour has been added, mix only until the ingredients are combined. Overmixing can develop too much gluten and make the cake heavier.

Don’t Skip the Coffee

The coffee isn’t there to make the cake taste like coffee. Instead, it enhances and deepens the chocolate flavor. If you prefer not to use coffee, hot water can be substituted, although the chocolate flavor may be slightly less intense.

Let the Cake Cool Before Glazing

A completely cooled cake gives you much more control over the glaze. If the cake is still hot, the glaze can become too thin and slide straight off.

Make It Extra Chocolatey

For an even more indulgent version, add a handful of chopped dark chocolate along with the chocolate chips. You can also finish the cake with chocolate curls for a bakery-style presentation.

Make-Ahead Instructions

This cake is an excellent make-ahead dessert.

You can bake the Bundt cake a day in advance and keep it tightly covered at room temperature once completely cooled. Prepare the glaze shortly before serving, or glaze the cake several hours ahead and keep it covered.

In fact, allowing the cake to rest overnight can make the chocolate flavor even more pronounced.

How to Store Leftovers

Store leftover cake in an airtight container at room temperature for up to 3 days.

For longer storage, refrigerate it for up to 5 days, although the cake is best served after allowing refrigerated slices to come closer to room temperature.

Individual slices can also be wrapped well and frozen for up to 2 months. Thaw them overnight in the refrigerator or at room temperature before serving.

Final Thoughts

This Double Chocolate Bundt Cake is proof that an impressive dessert doesn’t have to be complicated. The rich cocoa cake, melted chocolate chips, and glossy chocolate glaze work together to create a dessert that is deeply satisfying without being overly fussy.

The Bundt shape does most of the decorating for you, while the simple chocolate glaze adds the finishing touch. Serve it at a celebration, bring it to a potluck, or keep it on the kitchen counter for an irresistible afternoon treat.

Once you take that first forkful of moist chocolate cake with little bursts of melted chocolate throughout, you may find yourself making this recipe whenever a serious chocolate craving strikes.
