Fudgy Brownie Batter Ice Cream – Closeup

Step-by-Step Instructions

Step 1: Prep the pan and melt the chocolate for the brownies

Place your ice cream maker canister in the freezer at least 24 hours before churning, unless your machine does not require pre-freezing. Preheat the oven to 350°F. Line an 8-inch square baking pan with parchment paper, leaving a little overhang on two sides for easy lifting.

In a medium microwave-safe bowl, combine 1/4 cup unsalted butter and 1/2 cup semisweet chocolate chips. Microwave in 20-second bursts, stirring well after each burst, until the mixture is smooth and glossy. Let it cool for 3 minutes so it is warm but not hot.

Step 2: Bake the fudgy brownie chunks

Whisk 1/2 cup granulated sugar and 2 tablespoons packed light brown sugar into the melted chocolate mixture. Add 1 large egg and 1 teaspoon vanilla extract, then whisk for about 30 seconds, until the batter looks shiny and slightly thickened.

Fold in 1/4 cup all-purpose flour, 2 tablespoons Dutch-process cocoa powder, and 1/4 teaspoon fine salt just until no dry streaks remain. Fold in 1/4 cup mini chocolate chips. Spread the batter evenly in the prepared pan. Bake at 350°F for 18 to 22 minutes, until the edges are set and a toothpick inserted into the center comes out with moist crumbs, not wet batter.

Cool the brownies in the pan for 30 minutes, then lift them out using the parchment. Freeze the slab for 20 minutes to firm it up, then cut it into 1/2-inch chunks. Keep the chunks in the freezer while you make the rest of the recipe so they stay firm when mixed into the ice cream.

Step 3: Start the chocolate ice cream base

In a medium saucepan, whisk together 1 cup heavy cream, 1 cup whole milk, 3/4 cup granulated sugar, 1/2 cup Dutch-process cocoa powder, 2 tablespoons light corn syrup, 1 teaspoon instant espresso powder if using, and 1/4 teaspoon fine salt. Set the pan over medium heat and cook, whisking often, until the mixture is steaming and the sugar and cocoa are fully dissolved, about 5 to 7 minutes. The mixture should reach about 160°F to 170°F, but it should not boil.

Step 4: Temper the egg yolks and finish the custard

Place 4 large egg yolks in a medium heatproof bowl and whisk until smooth. Slowly ladle about 1 cup of the hot chocolate mixture into the yolks while whisking constantly. This warms the yolks gently so they do not scramble. Pour the tempered yolk mixture back into the saucepan.

Cook over medium-low heat, stirring constantly with a heatproof spatula and scraping the bottom and corners of the pan, until the custard thickens slightly and reaches 175°F to 180°F, about 3 to 5 minutes. Do not let it boil. The custard should lightly coat the back of the spatula.

Place the chopped 4 ounces semisweet or bittersweet chocolate in a large heatproof bowl. Pour the hot custard through a fine-mesh strainer over the chocolate. Let it sit for 1 minute, then whisk until smooth. Whisk in the remaining 1 cup heavy cream and 2 teaspoons vanilla extract.

Step 5: Chill the ice cream base thoroughly

Press a piece of plastic wrap directly against the surface of the chocolate base to prevent a skin from forming. Refrigerate for at least 4 hours, or overnight, until very cold. For the best texture, the base should be 39°F or colder before churning. If you are in a hurry, set the bowl over an ice bath and stir for 10 minutes before refrigerating, but do not skip the full chill time.

Step 6: Make the brownie batter-inspired sauce

In a small saucepan, melt 3 tablespoons unsalted butter over medium-low heat. Whisk in 1/3 cup packed light brown sugar, 1/4 cup Dutch-process cocoa powder, and 1 tablespoon all-purpose flour until the mixture looks like a thick paste. Add 1/3 cup heavy cream, 2 tablespoons light corn syrup, and 1/8 teaspoon fine salt, then whisk until smooth.

Bring the sauce to a gentle simmer and cook for 2 minutes, whisking constantly. The sauce should reach at least 165°F, which cooks the flour and gives the ribbon a brownie batter-like body. Remove from the heat and stir in 1 teaspoon vanilla extract and 1/4 cup mini chocolate chips. The chips may melt partly, leaving little chocolate flecks, which is exactly what you want. Let the sauce cool to room temperature before layering it into the ice cream. It should be thick but spoonable.

Step 7: Churn the chocolate ice cream

Give the chilled chocolate base a good whisk. Pour it into your frozen ice cream maker canister and churn according to the manufacturer’s directions, usually 20 to 25 minutes, until it reaches a thick soft-serve consistency. During the last 1 minute of churning, add about three-quarters of the frozen brownie chunks. Save the remaining chunks for layering on top and through the middle.

Step 8: Layer, ribbon, and freeze

Spoon one-third of the churned chocolate ice cream into a chilled freezer-safe container. Drizzle with a few spoonfuls of the brownie batter sauce and scatter on some of the reserved brownie chunks. Repeat the layers twice more, finishing with a few bold ribbons of sauce and brownie pieces on top. Use a butter knife or skewer to make 2 or 3 gentle figure-eight swirls through the container. Do not overmix, or the ribbons will disappear into the ice cream.

Press parchment paper or plastic wrap directly onto the surface, cover tightly, and freeze at 0°F for at least 4 hours, or until firm enough to scoop. Let the ice cream sit at room temperature for 5 to 10 minutes before serving for the creamiest texture.

Pro Tips

Use Dutch-process cocoa for the deepest flavor: It gives the ice cream a smooth, dark chocolate taste that feels especially brownie-like.
Freeze the brownie chunks before adding them: Cold chunks hold their shape in the churned ice cream and are less likely to smear.
Cool the sauce before layering: Warm sauce can melt the freshly churned ice cream and muddy the ribbons.
Watch the custard temperature: Pull it from the heat at 175°F to 180°F. If it boils, the yolks can curdle and the texture may turn grainy.
Keep the swirls bold: Layer the sauce instead of stirring it all in. A few gentle passes with a knife are enough.

Variations

Mocha brownie batter ice cream: Increase the instant espresso powder to 2 teaspoons and use bittersweet chocolate for a deeper coffee-chocolate flavor.
Peanut butter brownie batter ice cream: Drop small spoonfuls of creamy peanut butter between the layers along with the brownie batter sauce.
Gluten-free version: Use a cup-for-cup gluten-free flour blend in both the brownies and the sauce. Make sure your chocolate chips and cocoa powder are certified gluten-free if needed.

Storage & Make-Ahead

Store the ice cream in an airtight, freezer-safe container with parchment paper or plastic wrap pressed directly onto the surface. It is best within 2 weeks, though it will keep for up to 1 month. For easier scooping, let it stand at room temperature for 5 to 10 minutes before serving. The brownie chunks can be baked, chopped, and frozen up to 2 months ahead. The ice cream base can be made 24 hours ahead and kept refrigerated. The brownie batter sauce can be made up to 1 week ahead and refrigerated; warm it in the microwave for 5 to 10 seconds at a time, stirring between bursts, until spoonable but not hot.
