Why You’ll Love This Beverage

This Sleepy Girl Mocktail is quick to make, tastes like a fizzy cherry spritz, and fits perfectly into an evening wind-down routine. It’s also easy to adjust depending on how sweet or tart you like it, and it feels like a treat without being heavy.

Ingredient Highlights

Tart cherry juice gives the mocktail its deep, fruity flavor and makes it feel like a true “nightcap” without alcohol. Magnesium powder blends into the juice best when you stir it thoroughly, and sparkling water adds that refreshing, calming fizz that makes the drink feel special.

Tips for Best Results

For the smoothest texture, mix the magnesium into the tart cherry juice first, then add ice and sparkling water after it’s fully dissolved. If you want it less sweet, use more sparkling water or a squeeze of lemon. If you want it sweeter, add a small drizzle of honey and stir well.

Variations

Three Sleepy Girl Mocktail variations including classic cherry spritz, tropical version, and still version

Keep it classic, go tropical, or skip the fizz for a still version.

For a more tropical version, swap half the tart cherry juice for pineapple juice. If you want a stronger citrus bite, use lime instead of lemon and garnish with a twist. For a “no fizz” version, replace sparkling water with cold still water or caffeine-free herbal tea that has been chilled.

FAQ

Can I make a Sleepy Girl Mocktail without magnesium powder?
Yes. It still works as a tart cherry spritz. Just skip the magnesium and proceed as written.

What’s the best tart cherry juice to use?
Unsweetened tart cherry juice gives you the best flavor and keeps the drink from becoming overly sweet.

Can I make it ahead of time?
You can mix the tart cherry juice and magnesium ahead, but add sparkling water right before drinking so it stays fizzy.
