Fudgy Brownie Bundt Cake with Chocolate Glaze
This Brownie Bundt Cake is a dense, fudgy brownie baked in a stunning ring shape and topped with a glossy chocolate glaze. It gives you that crackly top and chewy edge you love, but in a sliceable dessert that looks far fancier than the effort it takes.
The batter comes together in one bowl while the oven preheats. If you can stir a pan of brownies, you’ve got this.
Why This Brownie Cake Wins Every Time
The crumb is tight and fudgy, never cakey, with a deep cocoa flavor that leans on melted butter and a whisper of sour cream. That sour cream keeps each slice moist for days.
A simple chocolate glaze drapes over the fluted grooves, setting just firm enough to slice without cracking. It feels like a celebration but asks for nothing more than a bowl and a whisk.
Ingredients
- 3/4 cup (170g) unsalted butter, melted: the base for that shiny top
- 1 1/2 cups (300g) granulated sugar: whisked well into the warm butter to dissolve
- 3 large eggs, at room temperature: cold eggs can seize the melted butter
- 1/2 cup (120g) sour cream, at room temperature: keeps the crumb fudgy and tender
- 2 tsp vanilla extract: rounds out the chocolate
- 1 1/4 cups (160g) all-purpose flour: just enough structure without turning cakey
- 3/4 cup (65g) unsweetened cocoa powder: Dutch-processed gives a deep color and flavor
- 1 tsp baking powder: a tiny lift for that slight brownie rise
- 1/2 tsp fine sea salt: sharpens the chocolate
- 1 cup (170g) semi-sweet chocolate chips: extra pockets of melted chocolate
- For the glaze: 1/2 cup (120ml) heavy cream and 4 oz (115g) chopped dark chocolate
Variations / Substitutions
- Darker flavor: swap the semi-sweet chips for bittersweet and add 1 tsp instant espresso powder to the batter.
- Nutty crunch: fold 1/2 cup toasted chopped pecans or walnuts in with the chocolate chips.
- White chocolate swirl: use white chocolate chips in the batter and drizzle with a white chocolate glaze instead.
- Peppermint twist: replace the vanilla with 1/2 tsp peppermint extract and scatter crushed candy canes over the warm glaze.

How to Make Brownie Bundt Cake
Step 1: Melt and Whisk the Wet Base
Preheat the oven to 350°F (175°C) and generously grease a 10-cup bundt pan with butter, then dust with cocoa powder. In a large bowl, melt the 3/4 cup butter. Off the heat, whisk in the 1 1/2 cups sugar, 3 eggs, 1/2 cup sour cream, and 2 tsp vanilla until the mixture is smooth and the sugar has started to dissolve.
The batter will look glossy and thick, with no streaks of egg white. That smoothness is what gives you the crackly brownie top later.
Step 2: Sift in the Dry Mix
Place a fine-mesh sieve right over the bowl and sift in the 1 1/4 cups flour, 3/4 cup cocoa powder, 1 tsp baking powder, and 1/2 tsp salt. Whisk gently until no dry pockets remain, but stop as soon as you see a uniform dark batter.
The mixture will be dense and almost like frosting. A few tiny lumps are fine; overmixing can make the crumb tough.
Step 3: Fold in the Chocolate
Scatter the 1 cup chocolate chips over the batter and fold with a spatula until they disappear into the dark mixture. You’ll spot little bumps of chocolate dotted throughout.
Those chips will soften into molten pockets as the cake bakes, giving you extra gooey bites.
Step 4: Bake the Bundt
Scrape the batter into the prepared bundt pan and smooth the top with the spatula. Bake for 40 to 45 minutes, until a toothpick inserted in the deepest part comes out with a few moist crumbs.
The surface will puff slightly and develop a papery, crackled layer. The kitchen will smell intensely of chocolate.
Step 5: Drizzle and Slice
Let the cake rest in the pan for 10 minutes, then invert it onto a wire rack to cool completely. While it cools, make the glaze: heat the 1/2 cup heavy cream until steaming, pour it over the 4 oz chopped chocolate, let sit 2 minutes, then stir until silky. Spoon the warm glaze over the top of the cooled cake, letting it drip down the grooves. Slice into thick wedges while the glaze is still slightly soft.
The glaze will set to a glossy sheen that catches the light. Serve wedges with the rich, fudgy interior exposed.
Tips for a Perfect Brownie Bundt
- Grease every crevice of the bundt pan with softened butter and dust inside with cocoa powder instead of flour. Cocoa won’t leave white patches on the dark cake.
- Bring the eggs and sour cream to room temperature before mixing. Cold ingredients can cause the melted butter to firm up and make the batter lumpy.
- Start checking for doneness 5 minutes before the earliest time. A slightly under-baked center keeps everything fudgy rather than dry.
- For the cleanest slices, use a sharp serrated knife and wipe the blade between cuts.
- If you don’t have a bundt pan, bake the batter in a greased 9-inch springform pan for about 35 to 40 minutes.
Bake times can shift with your pan, so check for moist crumbs on a toothpick rather than relying on the clock alone.
| Pan Type | Approx. Time |
|---|---|
| Light metal bundt | 42-47 mins |
| Dark nonstick bundt | 37-42 mins |
| Silicone bundt | 45-50 mins |
Keeping Your Brownie Bundt Fresh
- Refrigerate – Store the cake tightly covered at room temperature for up to 3 days, or in the fridge for up to 5 days. Bring refrigerated slices to room temp for the best texture.
- Reheating – A 15-second zap in the microwave warms a slice back to that just-baked fudgy state.
- Serve Cold – Chilled slices are almost like fudge. Enjoy them straight from the fridge if you like a denser bite.
What to Serve With Brownie Bundt Cake
A scoop of vanilla ice cream is the obvious partner, the cold creaminess cutting through the dense, rich chocolate. A dusting of flaky sea salt over the glaze intensifies the chocolate flavor even more. For a dinner party, serve with a simple raspberry coulis, because the tart fruit brightens each bite.
Frequently Asked Questions
Can I use a brownie mix instead?
Yes. Prepare one family-size boxed brownie mix (for a 9×13 pan) according to package directions, then bake it in the greased bundt pan for roughly the same time, checking 5 minutes early.
Why did my cake stick to the pan?
Bundt pans have many crevices. Be generous with the butter and cocoa dusting, and let the cake rest only 10 minutes in the pan before inverting. Leaving it longer can cause steaming and sticking.
How do I get that shiny crackle top?
Whisking the sugar thoroughly into the warm melted butter until it starts to dissolve creates the signature shiny layer. Don’t rush that first step.
Can I freeze this cake?
Absolutely. Wrap the completely cooled, unglazed cake tightly in plastic and freeze for up to 2 months. Thaw overnight at room temperature, then glaze before serving.
