No-Churn Brownie Ice Cream Cake with a Fudgy Brownie Base
A brownie ice cream cake that needs no ice cream maker and comes together with three simple layers. A chewy, fudgy brownie on the bottom, a thick no-churn vanilla ice cream in the middle, and a glossy chocolate fudge on top. You can make it days ahead, and it slices cleanly straight from the freezer.
What Makes This Brownie Ice Cream Cake So Good
The brownie base stays dense and fudgy even when frozen. Because we use melted butter and a high fat content, it never turns rock hard.
The no-churn ice cream is just whipped cream folded into sweetened condensed milk. No machine, no churning, and it stays soft and scoopable. The fudge topping cracks slightly when you cut into it, giving you that classic ice cream cake look without any fuss.
Ingredients
- 12 tbsp unsalted butter: melted, plus a little extra for the pan
- 1 cup (200 g) granulated sugar
- 2 large eggs: at room temperature
- 1 tsp vanilla extract
- ½ cup (60 g) unsweetened cocoa powder: natural or dutch-process both work
- ¾ cup (95 g) all-purpose flour: spooned and leveled
- ¼ tsp kosher salt
- 2 cups (480 ml) heavy cream: cold, for the ice cream layer
- 1 can (14 oz / 400 g) sweetened condensed milk: full fat
- 1 tsp vanilla extract: for the ice cream
- ½ cup (85 g) mini chocolate chips: optional, for the ice cream
- 1 cup (170 g) semi-sweet chocolate chips: for the fudge topping
- ⅓ cup (80 ml) heavy cream: for the fudge
- 1 tbsp unsalted butter: for the fudge
Variations / Substitutions
- Dairy-free: swap the heavy cream for chilled full-fat coconut cream, the condensed milk for a vegan sweetened condensed milk, and use a plant-based butter. The fudge can be made with dark chocolate and coconut cream.
- Mix-ins: fold ⅓ cup crushed chocolate sandwich cookies or chopped toasted pecans into the ice cream layer.
- Flavor switch: add 1 tsp peppermint extract to the ice cream and use dark chocolate for the fudge, or swirl in ⅓ cup peanut butter before freezing.
- Store-bought brownie shortcut: use an 8×8 pan of prepared brownie mix, but bake it 3 to 4 minutes less than the box says so it stays extra moist when frozen.

How to Make No-Churn Brownie Ice Cream Cake
Step 1: Bake the Brownie Base
Preheat the oven to 350°F (175°C) and line an 8×8-inch square pan with parchment paper, leaving a little overhang on two sides. In a large bowl, whisk the 12 tbsp melted butter and 1 cup sugar until the sugar looks damp. Add the 2 eggs and 1 tsp vanilla and whisk again until the mixture is thick and glossy. Sift in the ½ cup cocoa powder, ¾ cup flour, and ¼ tsp salt, then stir with a spatula just until no dry streaks remain.
The batter will be very thick. Spread it evenly into the prepared pan and bake for 22 to 25 minutes. The edges will look set and pull away from the sides, and a toothpick inserted in the center should come out with a few moist crumbs. Let the brownie cool completely in the pan on a wire rack before you add the ice cream layer.
Step 2: Whip the Ice Cream Layer
In a chilled large bowl, beat the 2 cups cold heavy cream with a hand mixer on medium high until stiff peaks form. Be careful not to walk away: the cream goes from soft mounds to firm peaks quickly. Gently fold in the can of sweetened condensed milk and 1 tsp vanilla with a spatula until no white streaks remain, then fold in the ½ cup mini chocolate chips if you are using them.
Scoop the ice cream mixture onto the completely cooled brownie base. Spread it into an even layer with an offset spatula, smoothing the top. Cover the pan with plastic wrap and freeze for at least 2 hours, until the top feels firm to the touch.
Step 3: Pour the Fudge Topping
Place the 1 cup semi-sweet chocolate chips in a heatproof bowl. In a small saucepan, heat the ⅓ cup heavy cream and 1 tbsp butter over medium heat just until you see tiny bubbles around the edges (do not let it boil). Pour the hot cream over the chocolate chips and let it sit for 1 minute, then whisk until smooth and glossy.
Let the fudge cool on the counter for 5 to 10 minutes so it thickens slightly but is still pourable. Take the cake out of the freezer, remove the plastic wrap, and pour the fudge over the firm ice cream layer. Tilt the pan gently to spread it to the edges, or use a spatula to guide it. Work quickly because the fudge will start to set as soon as it hits the cold ice cream. Return the pan to the freezer, uncovered, for at least 30 minutes so the fudge hardens into a glossy shell.
Step 4: Slice and Serve the Cake
Run a thin knife under hot water for a few seconds, wipe it dry, and run it around the inside of the pan. Use the parchment overhang to lift the whole cake out and set it on a cutting board. Dip the knife in hot water again, wipe it, and cut straight down through the fudge, ice cream, and brownie in one motion.
Wipe the knife between slices for the cleanest edges. The brownie base cuts cleanly without crumbling, and the ice cream stays creamy right out of the freezer. Serve the slices on chilled plates and eat right away.
Tips for the Best Brownie Ice Cream Cake
- Let the brownie cool all the way to room temperature, then pop it in the fridge for 10 minutes. A cold base keeps the ice cream layer from melting when you spread it on.
- Use full-fat, not light, sweetened condensed milk. The extra fat is what keeps the ice cream soft enough to scoop straight from the freezer.
- If your fudge topping has thickened too much while cooling, stir in a splash of warm cream a teaspoon at a time until it pours easily again.
- Line the pan with parchment. Even a well-greased pan can stick in spots, and the parchment makes lifting out the whole cake effortless.
The bake time shifts slightly with the pan size you use:
| Pan size | Bake time (brownie only) |
|---|---|
| 8×8-inch | 22 to 25 mins |
| 9×9-inch | 20 to 22 mins |
| 9×13-inch | 18 to 20 mins |
Storing Leftovers
Cover the cake tightly with a layer of plastic wrap followed by foil, and keep it in the freezer for up to 1 week. Let it sit at room temperature for 10 to 15 minutes before slicing so the knife goes through the fudge without cracking.
Frequently Asked Questions
Can I use a boxed brownie mix for the base?
Yes, and it works well. Bake the mix in an 8×8-inch pan but pull it out 3 to 4 minutes earlier than the box says. A slightly underbaked brownie stays fudgier when frozen.
Why did the fudge crack when I cut the cake?
Cold fudge can be brittle. Let the whole cake sit at room temperature for about 10 minutes before slicing, and use a warm, dry knife.
Can I leave out the fudge topping?
You can skip it for a simpler cake, but the texture contrast is what makes it feel like a classic ice cream cake. The brownie and ice cream alone taste great, just a little less decadent.
What if I want to add a swirl instead of chocolate chips?
Fold a ribbon of peanut butter, salted caramel, or raspberry jam into the ice cream right before you spread it. Swirl it gently with a knife so it stays in distinct pockets.
