Ingredients at a glance

Core ingredients are simple: water, granulated sugar, raspberry extract, and blue food coloring. Optional mixes like Kool-Aid add punch when you want a playful twist.

Gear options and estimated time

• Ice cream maker — needs a pre-frozen drum; about 20 minutes churn time.
• Ninja Slushi machine — uses the machine’s freeze setting; roughly 30 minutes.
• Blender — fastest option; reaches slush consistency immediately with crushed ice or chilled club soda.

Blue raspberry slushie: step-by-step methods you can make at home

Follow one of these clear methods to get icy texture and bold berry notes fast. Pick the right method for your time and gear, then follow the measurements so flavor stays bright and not watery.

Ice cream maker method (about 20 minutes churn time)

In a large bowl, dissolve 1 cup sugar into 4 cups cold water. Stir in 1 1/2 tsp McCormick Raspberry Extract and 4–6 drops McCormick Neon Blue Food Coloring.

Pour into a 1.5-qt ice cream maker with a drum frozen at least 24 hours. Churn about 20 minutes until slushy. This yields four 1-cup servings that hold shape but still sip through a straw.

Ninja Slushi machine method (freeze-and-churn, ~30 minutes)

Whisk 0.22 oz Mixed Berry Kool-Aid with 1/2 cup sugar, 4 cups cold water, and 2 tsp raspberry extract. Pour into the machine and select the Slush setting.

Let it run roughly 30 minutes until set. Because this machine freezes the liquid, crystals stay fine and the flavor doesn’t taste watered down as it melts.

Blender method with ice or chilled club soda

Chill 2 cups club soda for 15–20 minutes. Blend with 1/2 cup sugar, 1/2 tsp Blue Raspberry Lemonade Kool-Aid, and 3 cups crushed ice. Add up to 8 drops neon food coloring if desired.

Blend just until thick and pourable. Serve immediately for the coldest, lightest texture—this method is fastest in minutes.

Finding the perfect consistency and serving tips

Dial in consistency by adjusting water-to-ice ratios and churn time. Longer freeze yields firmer scoops; a few minutes less gives a looser pour perfect for sipping.

Measure raspberry extract carefully — extra can boost flavor but can overpower if you add too much. Serve in chilled cups and portion right away for best results.

• Plan time: pre-freeze the drum overnight, chill water to shave minutes on the machine, and chill club soda for 15–20 minutes for the blender.
• Batch dry mix ahead so you can switch methods any day of the year.
• Expect about four cups total from the ice cream maker; scale amounts as needed for extra guests.

Pro tips, color and flavor tweaks, and kid-friendly serving ideas

Tweak color, boost berry notes, and add fun garnishes to tailor this recipe for any crowd. Small, measured changes keep the texture and flavor balanced while making the cups look photo-ready.

Neon vs. classic: how much coloring to use

Start modest: 4–6 drops of McCormick Neon Blue food coloring gives a lively neon look. Add drop by drop to avoid staining and to control intensity.

Neon reads brighter in clear cups; classic blue produces a softer tone. You can omit coloring entirely if you prefer a subtler hue.

Boosting flavor with extract and mixes

For stronger berry notes, add measured raspberry extract and pair it with a Mixed Berry or Blue Raspberry Lemonade Kool-Aid mix. This deepens flavor without excess sugar.

Garnishes, mix-ins, and party service

• Striped paper straws and a lemon wheel add contrast and brightness.
• Try coconut flakes or a root beer twist for themed variations.
• Pre-chill cups and pitchers so the first pour shows peak color and clarity.

Storage, make-ahead, and nutrition notes

Serve machine-made slush immediately for best texture. If it sits, re-churn in the machine or pulse briefly in the blender to revive it.

Nutrition varies by method: one test gave about 188 calories per serving for the ice cream maker method and ~101 kcal for the Ninja method. Adjust sugar and garnishes to manage calories and fat.

Conclusion

When you want a quick, crowd-pleasing refresher, this recipe delivers every time.

Pick the method that fits your time — about 20 minutes for an ice cream maker, roughly 30 for a slush machine, or immediate results from a blender. You’ll get icy texture and bright raspberry flavor with minimal effort.

Scale the core mix for parties, tweak color and extract, and watch kids and adults light up. Keep an eye on calories and fat by adjusting sugar and portions. Save this information to your favorite recipes list and enjoy cold drinks all season long.
