- Measuring spoons
- Heat-safe jar or bottle (for syrup storage)
- Tall glass (12–16 oz)

Ingredients
Vanilla Marshmallow Syrup
- 1 cup granulated sugar
- 1 cup water
- 1 tsp vanilla extract
- ½–1 tsp marshmallow extract to taste
Soda (1 large glass)
- 2–3 tbsp vanilla marshmallow syrup
- ½–¾ cup cold sparkling water or club soda

Instructions
Make the Vanilla Marshmallow Syrup
- In a small saucepan, combine sugar and water.
- Heat over medium heat, stirring until the sugar is fully dissolved.
- Remove from heat and let cool slightly.
- Stir in vanilla extract and marshmallow extract.
- Cool completely and store in a sealed container in the refrigerator for up to 2 weeks.
Assemble the Soda
- Fill a tall glass with ice.
- Add vanilla marshmallow syrup.
- Pour in sparkling water and gently stir.
- Add optional cream, if desired. Serve immediately.
Notes
- Go light on marshmallow extract: It’s very strong—start with the smaller amount and add more only if needed.
- Balance the vanilla: Vanilla should be soft and cozy, not overpowering; pure vanilla extract works best.
- Creamy texture: For a classic cream-soda feel, add just a small splash of cream or half-and-half.
- Fizz control: Pour sparkling water slowly to keep the soda from foaming over.
- Make-ahead friendly: The syrup can be prepared up to 2 weeks in advance and stored refrigerated.
- Flavor twists: Try adding a drop of almond extract, or toast the marshmallows for garnish for a deeper flavor.
❓ Frequently Asked Questions
Can I use marshmallow syrup instead of extract?
Yes, but the flavor will be sweeter and less concentrated. You may need to reduce the sugar in the syrup slightly to keep it balanced.
Does this taste like a cream soda?
It has a similar vibe, but the marshmallow flavor makes it softer and sweeter than traditional vanilla cream soda.
Can I serve this warm?
This recipe is best served cold and fizzy. Warming it would remove the carbonation and change the texture.
Is this suitable for kids?
Absolutely. This is a non-alcoholic, kid-friendly drink that’s great for parties and family gatherings.
What sparkling water works best?
Plain sparkling water or club soda works best so the vanilla marshmallow flavor stays front and center.
Can I double or triple the recipe easily?
Yes. The syrup scales well—just multiply the ingredients and add sparkling water right before serving.
