Vegan butter pecan ice cream with caramel

Butter pecan ice cream is a sweet, buttery ice cream, often made with brown sugar, full of pecans that have been toasted in butter and salted. This dairy-free version keeps those flavors: the base is full-fat coconut milk sweetened with brown sugar, the pecans are toasted in a plant-based butter stick with a pinch of salt, and a soft coconut caramel is swirled through in ribbons. Each part is simple; what makes it come together is temperature. The nuts, the caramel and the base all need to be cold before they meet.

What makes it butter pecan, and what makes it vegan

Butter pecan is defined by its pecans: chopped nuts toasted in butter and salt, folded into a sweet, pale base that usually tastes of brown sugar or butterscotch. A dairy butter pecan ice cream gets its creaminess from milk and cream, often egg yolks too, and its butter from dairy butter. This version swaps each part:

A store-bought tub labeled dairy-free is not automatically vegan, so if you buy one, check the ingredients for eggs or honey as well as milk.

Toasting the pecans

Raw pecans taste mild and slightly waxy. Toasting them in butter over medium-low heat browns their surface and warms their oils, and the flavor turns deep and nutty. The pinch of salt matters more than it looks: butter pecan is meant to be a little salty against the sweet base, which is why the card calls for salted vegan butter as well.

Cues to watch for:

• Done: the pecans smell toasty, look a shade darker and the butter has been absorbed. A broken piece is light golden inside.
• Too far: a sharp, bitter smell and dark brown edges. Nuts go from toasted to scorched quickly, so stay at the stove for the last couple of minutes.

For candied pecans that stay crunchy a little longer in the freezer, sprinkle a tablespoon of brown sugar over the pecans for the last minute or two of toasting and stir until it melts and coats them; spread them out to cool so they do not set in a clump.

Let them cool completely on a plate. Warm nuts would soften the ice cream around them, and they only become crisp again once cool. The butter coating also helps them stay crisp longer once they are frozen in the ice cream, though they still soften slowly over days in the freezer. For the crunchiest bites, the card keeps a quarter of the pecans back to scatter over the top.

The coconut caramel

Coconut milk stands in for the cream in a classic caramel sauce. Simmered with brown sugar, the water cooks off, the sugars concentrate and darken, and the mixture thickens into a sauce that tastes of butterscotch with a light coconut note. Because it is so concentrated in sugar, it stays soft and spoonable even in the freezer, which is what makes it a good swirl.

How to tell when it is ready:

• It has darkened a shade, from beige to light caramel.
• It coats a spoon thickly and the bubbles have become slower and larger.
• A drop on a cold plate holds its shape instead of running.

Do not worry if it looks a little thin in the pan: it thickens a good deal as it cools. If it sets too thick to drizzle once chilled, stir in a teaspoon or two of coconut milk. If it separates and looks oily, whisk it hard off the heat; a teaspoon of hot water helps bring it back together.

The same caramel is good warm over caramelized pears, and it keeps in a covered jar in the refrigerator. Refrigerate it within 2 hours of making it, and use it within 3 to 4 days, the window the USDA Food Safety and Inspection Service gives for refrigerated leftovers.

Why everything must be cold before swirling

A swirl only works if the caramel stays separate from the ice cream. Warm caramel melts the soft ice cream it touches, sinks to the bottom and leaves a sticky layer in the container and a plain ice cream on top. Cold caramel stays where you put it. The card has you chill the caramel alongside the base, so both are ready at the same time.

Swirl with restraint: layer the ice cream and caramel in thirds, then draw a knife through in a few S-shaped strokes. Stirring blends the caramel into the base, and the ribbons disappear.

Churned or no-churn

With an ice cream maker, whisk the cold base well before pouring it in, because the coconut fat firms on top in the fridge. The ice cream is ready when it looks like thick soft-serve. Add the pecans in the last minute so they mix in evenly without being ground down by the paddle.

Without one, freeze the base in ice cube trays, then process the cubes in a food processor until smooth. The blade breaks up the ice crystals the way a churning paddle would. Fold in the pecans and layer with the caramel as usual. No-churn ice cream is a little denser and firms up more in the freezer, so it is best eaten within a day or two.

With a pint-style ice cream processor, a machine that shaves a frozen pint, pour the cold base into the machine’s pint container, freeze it for the full time the maker gives (usually around 24 hours), process it on the ice cream setting, then add the pecans with the mix-in function. Layer the caramel in afterwards with a spoon, in a separate container if the pint is full. The full recipe is more than one pint, so freeze the rest separately or use the ice-cube-tray method for it.

The base follows the same method as vegan pistachio ice cream, where the reasons for cooking it with cornstarch and chilling it thoroughly are explained in more detail.

Substitutions

• Brown sugar: light or dark both work. Dark brown sugar gives a stronger molasses flavor. Granulated sugar works in the base but loses the butterscotch character.
• Vegan butter: refined coconut oil works for toasting the pecans, but add a second pinch of salt, since coconut oil is unsalted.
• Pecans: walnuts are the closest swap. For a nut-free version, toast pumpkin seeds in a nut-free vegan butter instead; it becomes a brown sugar caramel ice cream with a different crunch.
• A softer scoop: a teaspoon or two of vodka stirred into the cold base before churning keeps the ice cream a little softer straight from the freezer, because alcohol lowers the freezing point. It is optional; leave it out for children or anyone avoiding alcohol.
• Coconut milk: use full-fat canned coconut milk. Light coconut milk and carton plant milks have too little fat and give an icy, hard ice cream, and they make a thinner, less rich caramel.

Common mistakes

• Bitter pecans: they were toasted too long or over high heat. Keep the heat at medium-low and keep stirring.
• Caramel too runny to swirl: it was not simmered long enough. Return it to the pan and simmer a few more minutes, then chill again.
• Caramel hard and chewy in the ice cream: it was cooked too far. Next time, take it off the heat as soon as it coats the spoon thickly.
• Soupy after churning: the base or the machine’s bowl was not cold enough.

Storing and serving

Keep the ice cream in a covered container with parchment paper pressed onto the surface. FoodSafety.gov notes that freezer storage guidance is “for quality only”, and that frozen foods stored continuously at 0°F (-18°C) or below “can be kept indefinitely”; the texture is what declines, as the ice cream turns icy and the pecans soften, so it is at its best within a couple of weeks. Let it stand at room temperature for 10 to 15 minutes before scooping, and put it back in the freezer straight after: ice cream that melts and refreezes turns icy, and the USDA Food Safety and Inspection Service advises discarding perishable food left at room temperature for more than 2 hours (1 hour if the temperature is over 90°F).

For a frozen dessert with no cooking at all, banana nice cream is blended from frozen bananas in a few minutes.

Allergy and ingredient notes

This recipe contains tree nuts (pecans) and coconut. Plant-based butter sticks are made from different oils, and some contain soy or cashews, so check the label if you avoid either. The pumpkin seed swap above, with a nut-free vegan butter, makes it nut-free, but coconut milk is the base, so there is no simple swap for anyone who avoids coconut.
