Made with cocoa powder and real semisweet chocolate, this double chocolate ice cream is a rich, decadent frozen custard. It’s my go-to base for chocolate-forward flavors like rocky road or chocolate Oreo, and it’s easy to turn into a triple chocolate treat by adding mini chocolate chips or a fudge swirl during churning.
What I love about this recipe is how easy it is to customize. Swapping the type of chocolate — semisweet, bittersweet, or darker varieties — changes the flavor profile noticeably. Semisweet offers a well-balanced sweetness, while bittersweet yields a deeper, slightly bitter, almost coffee-like note. This custard-style base gives exceptionally creamy scoops without the need for stabilizers.
Ingredients for Double Chocolate Frozen Custard
This double chocolate ice cream combines cocoa powder and chopped semisweet chocolate in a cooked custard base for an intensely chocolatey, velvety frozen dessert. Common substitutions appear in the notes for each ingredient where helpful.
- Granulated sugar. Sweetens the custard and lowers the freezing point to improve scoopability.
- Whole milk. Provides body and flavor; lower-fat milks will produce a firmer, icier result.
- Heavy cream. Adds the richness and smooth texture characteristic of custard-style ice cream.
- Cocoa powder. Use unsweetened cocoa powder; either natural or Dutch-processed will work and intensifies the chocolate flavor.
- Vanilla extract. Enhances the chocolate without competing with it; vanilla bean paste isn’t necessary here.
- Salt. A small pinch brightens and balances the sweetness and chocolate notes.
- Egg yolks. Tempered and cooked into the base, they create a silky, custardy texture.
- Semisweet chocolate. Chopped into small pieces and melted into the custard for a second layer of chocolate.
How to Make Homemade Double Chocolate Ice Cream
If you haven’t made a custard-based ice cream before, don’t worry — this method is straightforward and yields a luxuriously creamy result. The egg yolks are tempered with warm cream, then the mixture is cooked gently and finished by melting in chopped chocolate before chilling and churning. The recipe below includes step-by-step details to help even beginners succeed.
Equipment for Making Ice Cream at Home
An ice cream maker is required for the smooth, aerated texture characteristic of frozen custard. A small 1.5–2 quart machine is ideal for home batches. A heavy-duty spatula and a large heat-safe bowl make handling the warm custard easier, and a sturdy ice cream scoop produces neat servings once the ice cream is fully frozen.
How to Make the Chocolate Custard Base
Start by combining heavy cream, whole milk, cocoa powder, vanilla, and half of the sugar in a medium saucepan over medium heat. Stir occasionally and press any dry cocoa clumps against the pot side with a spatula to help them dissolve. Heat until the mixture is steaming and very close to simmering, but do not let it boil.
Whisk four egg yolks with the remaining sugar in a large, heat-safe bowl until the mixture becomes pale and ribbon-like — this aeration helps the yolks heat evenly when you temper them with the warm cream.
Tempering the Egg Yolks
Slowly add a few tablespoons of the warm chocolate cream to the yolks while whisking constantly. Repeat until you’ve added roughly half of the warm liquid, which brings the yolks up to temperature without scrambling them. Then pour the tempered yolks back into the pot with the remaining cream and return the pot to medium heat.
Finish Cooking the Chocolate Custard
Cook the combined custard over medium heat, stirring, until it thickens enough to coat the back of a spoon or reaches around 170°F (75°C). Remove from heat and place chopped semisweet chocolate in a large heat-safe bowl. Pour a small amount of the hot custard over the chocolate and whisk to melt it, then stir in the remaining custard until fully combined. Cover and chill the custard in the refrigerator for at least four hours or until cold to the touch.
How to Churn Double Chocolate Ice Cream
Place your freezer container in the freezer before churning so it’s fully cold when you transfer the churned ice cream. Churn the chilled custard according to the ice cream maker’s instructions. Because this custard is thick, expect a shorter churn time — usually 10–15 minutes — until the ice cream forms rounded domes above the paddle. Transfer to a chilled, airtight container, and freeze for at least four hours to firm up, or serve immediately for a soft-serve texture.
A Secret for Scoopable Homemade Ice Cream
This custard is fairly thick, so check it near the ten-minute mark. You’ll know it’s ready when the mixture forms large, rounded domes above the paddle — that indicates enough air has been incorporated and the texture is right for finishing in the freezer.
Mix-In Ideas for Homemade Chocolate Frozen Custard
- Rocky road: mini marshmallows, chopped almonds, and fudge pieces.
- Triple chocolate: add mini chocolate chips or a fudge swirl.
- Cookie-studded: fold in bite-sized cookie pieces for extra chocolate texture.
- Oreo-style: mix in crushed sandwich cookies for a chocolate cookie ripple.
FAQs about Homemade Chocolate Ice Cream
How much ice cream does one batch make?
This recipe yields just under 2 quarts — roughly 8 scoops — with room to fold in up to ½ cup of mix-ins during churning.
Can I add mix-ins?
Yes — add them in the final five minutes of churning for even distribution and to avoid overworking the machine.
Can I use more egg yolks?
Yes. You can increase to six yolks for an even richer custard, though the flavor will be very rich with the chocolate added.
Does this ice cream scoop easily?
It’s slightly firmer than a plain French vanilla custard but still scoops well. For extra scoopability, allow the frozen pints to sit at room temperature for a few minutes before scooping.
Other Recipes You May Enjoy
If you enjoy custard-based ice creams, try a French vanilla frozen custard, a seasonal pumpkin pie custard with pie crust pieces, or a black cherry frozen custard with a jam swirl. This chocolate base also works beautifully sandwiched between cookies to make ice cream sandwiches.
Dish Cleanup: Gonna Take a While
I rate cleanup effort on a 1–5 scale, where 1 is minimal and 5 is a full kitchen sink load. This recipe rates about a 4 because you’ll use a pot, a large mixing bowl, a whisk, and your ice cream canister. Rinsing bowls and utensils soon after use makes cleanup far easier.

Ingredients
- ⅔ cup (166 g) granulated sugar, divided
- 1 ½ cups (350 ml) whole milk
- 1 ½ cups (350 ml) heavy cream
- ¼ cup (20 g) unsweetened cocoa powder
- 1 teaspoon vanilla extract
- Pinch of salt
- 4 large egg yolks
- 2 ounces (56 g) semisweet chocolate, chopped
- ½–1 cup mix-ins (optional): mini chips, chopped nuts, marshmallows, cookie pieces
Instructions
Making the Custard Base
- In a medium saucepan over medium heat, combine half the sugar (⅓ cup or 83 g), whole milk, heavy cream, cocoa powder, vanilla, and a pinch of salt. Stir occasionally and press cocoa against the pot sides with a spatula to break up clumps. Heat until steaming and just about to simmer; do not boil.
- Meanwhile, whisk the four yolks with the remaining sugar in a large heat-safe bowl until pale and ribbon-like — when the mixture falls off the whisk in visible ribbons.
Tempering the Eggs
- Remove the warm cream from heat. Add 1–2 tablespoons of the warm cream to the yolks at a time, whisking vigorously to combine. Repeat until about half the warm cream has been incorporated.
- Pour the tempered yolks back into the saucepan and return to medium heat. Cook, stirring, until the custard thickens enough to coat the back of a spoon or reaches about 170°F (75°C), about 5–10 minutes. Do not let the custard boil.
Adding the Chocolate
- Place the chopped semisweet chocolate in a large bowl. Pour about ¼ cup (60 ml) of the hot custard over the chocolate and whisk until melted. Stir in the remaining custard until smooth.
- Cover and chill the custard in the refrigerator for at least four hours, or until cold to the touch. Chill up to one day for convenience.
Churning
- When the custard is fully chilled, churn in your ice cream maker according to the manufacturer’s directions. For this thick custard, churning typically takes 10–15 minutes. Add ½–1 cup of mix-ins during the last five minutes if using.
- For soft serve, enjoy immediately. For scoopable ice cream, transfer to an airtight container and freeze at least four hours until firm.
Notes
If the custard boils and the eggs curdle, you can usually rescue the batch by straining it through a fine mesh strainer to remove lumps before chilling. Store the finished ice cream in an airtight container for best quality; it’s best within a week but can keep up to three months.
