If you love coffee and ice cream, learning how to make coffee ice cream at home is a perfect project. You get complete control over the flavor and ingredients, resulting in a rich, caffeinated treat that’s far better than anything from the store.
It’s easier than you might think. With a few basic techniques and some patience, you can create a smooth, creamy dessert that captures the true essence of coffee. Let’s get started on your new favorite frozen dessert.
How to Make Coffee Ice Cream
This guide covers the classic custard-based method, which uses egg yolks for incredible richness. We’ll also cover simpler no-churn and vegan options later. First, let’s gather what you need.
Essential Ingredients & Equipment
Quality ingredients make a big difference in the final product. Here’s your shopping and tool list.
Ingredients for Custard Base
- 2 cups heavy cream (cold)
- 1 cup whole milk
- 3/4 cup granulated sugar
- 5 large egg yolks
- 1/4 teaspoon fine sea salt
- 1 tablespoon pure vanilla extract
- 1/2 cup finely ground coffee (or 1/3 cup instant espresso powder)
Necessary Equipment
- Medium saucepan
- Mixing bowls (at least two)
- Whisk
- Fine-mesh strainer
- Ice cream maker
- Airtight container for freezing
Step-by-Step Instructions
Follow these steps carefully for the best results. The key is patience during the cooking and chilling phases.
Step 1: Steep the Coffee
In your saucepan, combine the milk, cream, and half of the sugar. Warm the mixture over medium heat until it just begins to steam; small bubbles will form around the edges. Do not let it boil.
Remove from heat and immediately stir in the finely ground coffee. Cover the pan and let it steep for 1 hour. This infuses the dairy with deep coffee flavor. If your using espresso powder, you can add it later in step 3.
Step 2: Prepare the Egg Yolks
While the coffee steeps, whisk the egg yolks, remaining sugar, and salt in a separate bowl. Whisk until the mixture becomes pale yellow and slightly thickened. This step is called “making the ribbon.”
Step 3: Make the Custard (Tempering)
- After steeping, strain the coffee-infused dairy through a fine-mesh strainer into a clean bowl, pressing on the grounds to extract all liquid. Discard the grounds. Return the strained dairy to the saucepan and re-warm it.
- Slowly, while whisking the egg yolk mixture constantly, pour a small stream of the warm dairy into the yolks. This gradual process is called tempering and it prevents the eggs from scrambling.
- Once about half the dairy is incorporated, pour the entire yolk mixture back into the saucepan with the remaining dairy.
Step 4: Cook to Thicken
Cook the combined mixture over low heat, stirring constantly with a spatula. Scrape the bottom to prevent sticking. Cook until the custard thickens enough to coat the back of the spatula. If you draw a line with your finger, the line should hold its shape. This is the “nappe” stage.
Immediately remove from heat and stir in the vanilla extract (and instant espresso powder if you’re using that instead of grounds).
Step 5: Chill Thoroughly
Strain the custard one more time into a clean bowl to catch any accidental bits of cooked egg. Place plastic wrap directly on the surface of the custard to prevent a skin from forming. Refrigerate for at least 4 hours, but preferably overnight. The mixture must be completely cold before churning, or your ice cream won’t freeze properly.
Step 6: Churn and Freeze
Pour the chilled custard into your ice cream maker. Churn according to the manufacturer’s instructions, usually 20-30 minutes, until it reaches a soft-serve consistency.
Transfer the churned ice cream to an airtight container. Press a piece of parchment paper directly on the surface, then seal the lid. Freeze for at least 4-6 hours to firm up before serving.
No-Churn Coffee Ice Cream Recipe
Don’t have an ice cream maker? No problem. This method uses whipped cream for a super easy, still delicious version.
Ingredients
- 2 cups heavy cream, very cold
- 1 (14 oz) can sweetened condensed milk
- 2-3 tablespoons instant espresso powder
- 1 tablespoon hot water
- 1 teaspoon vanilla extract
- Pinch of salt
Instructions
- Dissolve the instant espresso powder in the hot water. Let it cool completely.
- In a large bowl, whip the heavy cream until stiff peaks form.
- In another bowl, whisk the sweetened condensed milk, cooled espresso mixture, vanilla, and salt.
- Gently fold the whipped cream into the condensed milk mixture until no white streaks remain. Be careful not to deflate the cream.
- Pour into a loaf pan or container, cover, and freeze for at least 6 hours.
Dairy-Free & Vegan Coffee Ice Cream
You can enjoy this treat even if you avoid dairy. The base relies on full-fat coconut milk for creaminess.
Ingredients
- 2 (13.5 oz) cans full-fat coconut milk, chilled
- 2/3 cup maple syrup or agave nectar
- 1/4 cup finely ground coffee or 3 tbsp instant espresso
- 1 tablespoon vanilla extract
- Pinch of salt
Instructions
- If using ground coffee: Heat 1 can of coconut milk until steaming. Remove from heat, add ground coffee, steep for 1 hour, then strain.
- Whisk together the steeped coconut milk (or both cans if using espresso powder), sweetener, vanilla, and salt until smooth.
- Chill the mixture thoroughly, at least 4 hours.
- Churn in an ice cream maker, then freeze until firm.
Pro Tips for the Best Flavor & Texture
A few small details can take your ice cream from good to exceptional.
Choosing Your Coffee
- Use a coffee you love to drink. A medium or dark roast will give the strongest flavor.
- For the steep method, a fine grind (like for espresso) works best for maximum flavor extraction.
- Instant espresso powder is a fantastic, no-grit option that delivers pure coffee taste.
Avoiding Ice Crystals
- Ensure your custard is completely cold before churning.
- Use an airtight container for freezing.
- Press parchment paper on the surface before sealing the lid; this minimizes air exposure.
- Consume within 2-3 weeks for the best texture.
Flavor Variations & Mix-Ins
Once you master the base, try these fun additions. Fold them in during the last minute of churning.
- Chocolate Chips or Cacao Nibs: For a mocha twist.
- Toasted Pecans or Almonds: Adds a wonderful crunch.
- Crushed Chocolate-Covered Espresso Beans: Double the coffee kick.
- A swirl of homemade fudge or caramel sauce.
Troubleshooting Common Issues
If something doesn’t go as planned, here’s how to fix it.
Ice Cream is Too Hard
This is often caused by to low sugar or fat. Sugar lowers the freezing point. Next time, ensure your measurements are accurate. Also, let the ice cream sit on the counter for 5-10 minutes before scooping.
Ice Cream is Too Soft
This usually means the custard wasn’t chilled enough before churning, or the ice cream maker bowl wasn’t fully frozen. Always chill your base overnight and freeze your ice cream maker bowl for the full time recommended, often 24 hours.
Icy or Grainy Texture
This is from large ice crystals. It can happen if the freezing process is to slow or if there’s to much water in the base. Using full-fat dairy, ensuring a proper custard cook, and freezing quickly in a pre-chilled container helps.
Custard Curdled
If you see bits of cooked egg, you heated the mixture to quickly. Don’t panic! Straining it through a fine-mesh sieve after cooking will usually remove all the lumps and salvage the custard.
Serving & Pairing Suggestions
Your homemade coffee ice cream is a dessert star on its own or with simple accompaniments.
- Scoop it into a waffle cone for a classic treat.
- Serve alongside a warm brownie or slice of chocolate cake.
- Drizzle with a little Kahlúa or amaretto for an adults-only float.
- Add a scoop to your morning iced coffee for an affogato-style breakfast (we won’t judge).
Frequently Asked Questions (FAQ)
Can I make coffee ice cream without an ice cream maker?
Yes, absolutely. The no-churn method outlined above is a great solution. It uses whipped cream to incorporate air, giving you a creamy texture without any special equipment.
How long does homemade coffee ice cream last?
For the best flavor and texture, enjoy it within 2-3 weeks. After that, it might develop freezer burn or become overly hard, though it will still be safe to eat.
Why is my coffee ice cream bitter?
Bitterness can come from over-steeping the coffee or using a very dark roast. Try steeping for exactly 1 hour and using a medium roast. If using instant espresso, make sure you’re using the recommended amount, as it’s very concentrated.
Can I use decaf coffee?
Of course. The process is exactly the same. Use decaffeinated coffee grounds or decaf instant espresso powder to get all the flavor without the caffeine.
How do I make strong coffee flavored ice cream?
For a more intense flavor, increase the amount of ground coffee by a tablespoon or two during steeping. Alternatively, use a high-quality instant espresso powder, which has a very concentrated taste. You can also add a teaspoon of espresso powder to the custard base even if you steeped grounds, for an extra kick.
What’s the best way to scoop hard ice cream?
Dip your ice cream scoop in warm water between scoops. This helps the scoop glide through the frozen ice cream cleanly, giving you perfect rounded scoops everytime.
Making your own coffee ice cream is a rewarding process. You can adjust the sweetness, the coffee strength, and the add-ins to create a dessert that’s perfectly tailored to your taste.
