Blue Moon Ice Cream

The ice cream truck that rolled through my Milwaukee neighborhood every July had a hand painted sign and a cooler full of Blue Moon, that impossible blue scoops that tasted like someone turned a fruit orchard into a cloud. I never knew what the flavor actually was, and frankly I still do not, but twenty years later I found myself standing in my kitchen at midnight with a bottle of blue food coloring and a desperate craving to recreate it.

My friend Sarah visited from the coast last August and stared at the blue ice cream in my freezer like it was an alien specimen. She took one bite, went quiet, and then ate the entire bowl without saying a word.

Ingredients

• Heavy cream (2 cups): The fat is what gives this ice cream its luxurious mouthfeel, so do not even think about substituting half and half.
• Whole milk (1 cup): Balances the cream so the result is silky rather than greasy.
• Granulated sugar (3/4 cup): Sugar lowers the freezing point, which keeps your ice cream scoopable straight from the freezer.
• Salt (pinch): Just enough to make all those sweet flavors pop.
• Egg yolks (4 large): These thicken the base into a proper custard and add a richness that eggless versions simply cannot match.
• Raspberry extract (1.5 teaspoons): The secret backbone of that mysterious Blue Moon fruitiness.
• Lemon extract (3/4 teaspoon): Adds the citrus brightness that makes the flavor so hard to pin down.
• Vanilla extract (1/2 teaspoon): Rounds everything out with a warm, familiar note.
• Blue food coloring (1 to 2 drops): Start with one drop and add more until you hit that nostalgic electric blue.

Instructions

Warm the dairy:

Pour the cream, milk, sugar, and salt into your saucepan and set it over medium heat, stirring gently until you see steam rising but no bubbles forming. The sugar should dissolve completely and the mixture should feel hot to the touch.

Temper the yolks:

Whisk your egg yolks in a bowl until slightly paler, then drizzle in about half a cup of the hot cream mixture in a thin stream while whisking like your ice cream depends on it. Pour this tempered mixture back into the saucepan slowly.

Cook to custard:

Stir constantly over low heat until the mixture coats the back of your spoon like a thin layer of paint, which usually takes five to seven minutes. If it boils, you will have scrambled yolks, so keep the heat low and patient.

Add the magic:

Take the pan off the heat and stir in the raspberry extract, lemon extract, vanilla extract, and that glorious blue food coloring. Keep stirring until the color is uniform and you see that iconic shade staring back at you.

Strain and chill:

Pour the custard through a fine mesh sieve into a clean bowl to catch any cooked bits, then let it cool to room temperature. Cover it tightly and refrigerate for at least four hours, though overnight makes it even better.

Churn it up:

Pour the chilled base into your ice cream maker and churn following the manufacturers directions until it looks thick, fluffy, and irresistible. This usually takes about twenty minutes.

Freeze to finish:

Transfer the soft ice cream into a freezer safe container with a lid and freeze for at least two hours so it firms up properly. Let it sit on the counter for five minutes before scooping for the best texture.

The afternoon I finally nailed this recipe, I carried a quart of it to my neighbors porch and we sat in plastic chairs eating blue ice cream off paper towels while their dog watched us with deep suspicion.

Getting That Blue Moon Flavor Right

The thing about Blue Moon is that nobody agrees on what it actually tastes like, and that is part of the charm. I have found that raspberry and lemon extracts get you closest to that fruity, slightly citrus mystery, but adding a tiny splash of orange extract pushes it into even more interesting territory.

Working With Your Ice Cream Maker

Every ice cream maker behaves differently, and I learned the hard way that a warm bowl means soupy results. Freeze your canister for a full 24 hours before churning, and make sure your base is completely cold straight from the fridge.

Serving and Storing Your Blue Moon

Homemade ice cream is best within the first week, when it is still creamy and scoopable without effort. After that, ice crystals can form, but a quick stir and a few minutes on the counter usually bring it back to life.

• Waffle cones and rainbow sprinkles are not optional if you want the full childhood experience.
• A warmed scoop slides through frozen ice cream much better than a cold one.
• Press plastic wrap directly against the surface before lidding to minimize ice crystals.

Some flavors are worth chasing across decades and kitchen counters, and this blue scoop of Midwestern magic is absolutely one of them. Grab a cone, sit somewhere uncomfortable, and eat it before it melts.

Recipe FAQs

→ What does Blue Moon Ice Cream taste like?

Blue Moon has a unique fruity-citrus flavor that's often described as a mix of raspberry, lemon, and vanilla with a hint of marshmallow sweetness. The exact flavor profile is famously debated, but the combination of raspberry and lemon extracts in this version comes close to the classic taste.

→ Can I make this without an ice cream maker?

Yes, you can pour the chilled custard into a shallow dish and freeze it, stirring vigorously every 30 minutes for about 3–4 hours to break up ice crystals. The texture won't be quite as smooth as machine-churned, but it will still be delicious.

→ Why is Blue Moon Ice Cream blue?

The signature color comes entirely from blue food coloring. Traditionally, it's a vivid sky-blue shade. Start with just 1–2 drops and adjust until you reach the intensity you want. Gel-based food coloring works especially well for vibrant results.

→ How long does homemade Blue Moon Ice Cream last in the freezer?

Stored in an airtight, freezer-safe container, it will keep well for up to 2 weeks. Beyond that, ice crystals may form and the texture can become grainy. Let it sit at room temperature for a few minutes before scooping for the best consistency.

→ Can I use natural food coloring instead?

Absolutely. Butterfly pea flower powder or liquid can produce a lovely blue hue naturally. The shade may differ slightly from the traditional look, and the flavor could be subtly affected, so start with a small amount and adjust to your preference.

→ What's the trick to getting a smooth, creamy texture?

The key steps are tempering the egg yolks properly so they don't scramble, cooking the custard gently until it coats the back of a spoon, straining it through a fine sieve, and chilling it thoroughly—ideally overnight—before churning. Each step ensures a silky final result.
