And while there are endless flavors to choose from, nothing compares to the rich, bold taste of coffee ice cream. But why settle for store-bought when you can make your own? Today, we are sharing our favorite recipe for homemade coffee ice cream that’s sure to impress even the pickiest of taste buds. With just a few simple ingredients and some patience, you’ll have a batch of the creamiest, most decadent coffee ice cream you’ve ever tasted. So grab a spoon and let’s get churning!
HOW WE CREATED THE BEST HOMEMADE COFFEE ICE CREAM RECIPE
We didn’t want to make just a good coffee ice cream. We wanted to create the best. So first, we researched the science and techniques behind making ice cream, and how to keep it creamy. The details of how to do this are included below. Then we used the best ingredients we could find to create this recipe. That made a big difference. Brands vary in quality, so we have listed the brands we used. We have no affiliates, so we mention brands just because they are better.
STARBUCKS VIA INSTANT ITALIAN ROAST COFFEE PACKETS – one packet contains 3.3 grams of instant microground coffee. We tried lots of different ways of adding coffee flavor, from espresso powder to making our own cup of espresso. But Starbucks instant packets were so good we stopped looking and threw out the other powders. An added bonus was that this was also the easiest. We used the Italian Roast, but there are other flavors to try.
VALRHONA CHOCOLATE– Valrhona produces some of the world’s finest chocolate; unique, artisan quality chocolate with complex, balanced and consistent flavors. Their chocolate is responsibly sourced from growers with whom they have long term partnerships and they have committed to assisting producers, protecting the environment and promoting innovation. Chocolate production is one of the major causes of destruction of the rain forest, and long term partnerships with stable growers is good way of preventing this destruction.
THE SCIENCE OF KEEPING THE COFFEE ICE CREAM SMOOTH AND CREAMY
THE SCIENCE OF ICE CREAM

We fell in love with European ice cream – dense and creamy, with elegant flavors. It was like nothing we could get back home. So, we researched the science and technique for making ice cream and learned how to make it ourselves. The key to the best flavor was to use the best quality, most flavorful ingredients. But the secret to keeping it smooth and creamy was a combination of ingredients and technique.
There is more to ice cream than just freezing quality ingredients. The key is making it smooth and creamy. This is actually more difficult than it seems. Ice cream stays smooth while it is being churned, but then it is put in the freezer in order to harden, and that’s when ice crystals form, ruining the smoothness.
There is a lot of science to keeping it smooth. Making ice cream requires a method and ingredients that prevent large ice crystals from forming. The method is accomplished with a properly designed ice cream maker that keeps all of the mixture moving, and freezes it quickly. The other key is using certain ingredients that keep the ice crystals small. Cultured cream, eggs, invert sugar and alcohol are the keys to keeping the ice crystals small and the mixture creamy.
INGREDIENTS
HORIZON ORGANIC CREAM – We think Horizon products taste better than any other dairy products we have tried. This is probably because the products are organic and from family farming partners. Just as important, Horizon is acertified B corporationthat has committed to becomingcarbon positive across their entire supply chain by 2025. We save money by buying this by the half gallon at a big box store.
HOMEMADE CRÈME FRAÎCHE FROM HORIZON CREAM – Crème fraîche is cultured cream, like sour cream, but with a much milder taste. The culture in it prevents ice crystals from forming once the ice cream has been churned and is hardening. We make crème fraîche from Horizon cream, which makes this an eco-friendly swap as well, since Horizon is taking action on climate change. We save money by making our own, but it’s also better, and it’s a real crème fraîche, made with a culture. And it’s easy to make because we use an Instant Pot.
EGGS – eggs increase the fat and protein in the mixture. The eggs are raw when whipped with the sugar, but are cooked when the hot cream is slowly added. It is important to bring the mixture to a safe temperature (160 degrees F., according to the USDA). This method will do that without having to go through the added steps of making a custard and risking over cooking the eggs. French ice cream is made with a custard, which requires cooking and tempering, so this method is much easier. Heating the eggs will also denature the protein in the eggs and prohibit ice growth.
INVERT SUGAR – We use corn syrup for the required invert sugar. It lowers the freezing point of water, making the ice crystals smaller and the ice cream smoother. Corn syrup is NOT the same as high-fructose corn syrup. Honey, and some syrups are partially invert sugars and will do the same thing, to some extent, so we use these for certain flavors. However, honey and syrup will add a lot of flavor.
WHOLESOME ORGANIC CANE SUGAR – Sugar lowers the freezing point. The sugar molecules interfere with the water molecules becoming organized into a solid as it freezes.
ALCOHOL– This lowers the freezing point, making the ice crystals small. It also keeps ice crystals from forming as the ice cream hardens. Too much, however, and the ice cream won’t freeze. Use one tablespoon of an 80 proof alcohol, and adjust the amount for liqueur that contain more or less alcohol.
HEILALA VANILLA PASTE – We use Heilala vanilla paste in ice cream because it has a wonderful vanilla flavor without adding anything else. Using a paste makes it so much easier than using a vanilla bean and scraping all the seeds out. The paste includes the seeds so the ice cream will have the traditional flecks in it.
AIR – Air is also an important ingredient. It softens the ice cream and provides insulation allowing the flavors to be tasted even though the ice cream is cold. The air is added continuously as the ice cream is churned.
THE ICE CREAM MAKER
Making ice cream also requires a method that prevents the cream from freezing solid. The mixture must be constantly churned in an ice cream maker to add air and to keep the ice crystals small, so the ice cream stays creamy. When selecting an ice cream maker, the important thing is that it keeps all of the mixture moving, and freezes it quickly. There should be very little space between the paddle and the walls of the container, and the paddle should be designed to turn over the mixture as it rotates. If there is a gap allowing too much ice cream to build up on the container walls it will cause ice formation. The temperature must be cold enough to freeze the mixture quickly, before ice forms.
We use aWhynterIce Cream maker (model ICM-200LS) which does an excellent job of freezing it quickly. It doesn’t require ice and rock salt or freezing the insert, so it is really easy and convenient. It has a capacity of 2 Quarts, but we found the ice cream is better when we make 1 Quart, so our recipe makes 1 Quart.
It also helps if everything is cold. Make the mixture and thoroughly chill it down to 45 degrees F. Before putting it in the ice cream maker. Making it the day before will ensure that it is thoroughly chilled and it also improves the flavor. Let the ice cream maker run for five minutes before putting the mixture in, so it freezes as fast as possible. Freeze a glass container to store the ice cream. And work quickly when the ice cream has finished churning. Allow it to harden overnight.
FOOD SAFETY
Ice cream is made from dairy products and eggs, so it is very important to take steps to ensure food safety. Follow the instructions in the recipe carefully.
- Start with everything washed in hot soap water, including knives and cutting boards.
- Use pasteurized cream.
- Simmer the cream and fruit mixture for two minutes to bring it to a safe temperature.
- Add the hot cream mixture to the egg mixture, which will bring the eggs up to 160 degrees F., the safe temperature for eggs.
- Fresh fruit can not be added after this, because it is not cooked and could contaminate the ice cream.
- Some recipes call for adding things after the ice cream is churned, such as nuts, preserves or chocolate. These should all be fresh, clean, and handled in a manner to keep them clean. Nuts should be toasted and cooled just prior to adding. Anything chopped should be done on a clean cutting board with a clean knife. Preserves should be a newly opened jar.
- The ice cream should be consumed within a week.

- 30 grams Valrhona Manjari 64% cacao chocolate Shaved into tiny slivers and frozen
Instructions
PREPARE THE STORAGE CONTAINER
- Put a glass storage container in the freezer.
MEASURE THE INGREDIENTS
- Use a scale to measure the ingredients – zeroing the scale between measurements. Into a small saucepan, measure the cream and corn syrup.Into the mixing bowl of the stand mixer, measure the egg, egg yolk, sugar, and salt. Into a small bowl, measure the crème fraîche, vodka, vanilla paste and instant coffee.
MIX THE INGREDIENTS
- In the stand mixer with the whisk attachment, whisk together the egg, egg yolk, sugar and salt for at least 2 minutes on medium speed.
- While the stand mixer is whisking the eggs and sugar, put the saucepan on the stove and bring the cream, corn syrup and vanilla bean (if you are using one) to a simmer and simmer for 2 minutes, stirring to combine.
- Switch the mixer to low speed and very slowly add the cream and corn syrup mixture. This should take about a minute.
- Continue whisking on low and add the crème fraîche, vodka, vanilla paste and instant coffee. Whisk just until combined.
- Refrigerate overnight, or you can use an ice bath to bring it down to 45° F, if you are in a hurry.
FREEZE THE MIXTURE
- Pre-chill the ice cream maker by letting it run for 5 minutes before adding the mixture.
- Pour into the ice cream maker and freeze according to the directions.
- When the ice cream maker is finished, quickly transfer the ice cream into the glass container that has been in the freezer, cover, and put the container back in the freezer to harden for ten minutes. Sprinkle the shaved, frozen chocolate over the ice cream and fold in with just a couple of folds. Return the ice cream to the freezer overnight.
- Store in the freezer for up to a week.
