Sugar-Free French Vanilla Syrup

This is the syrup behind our Sugar-Free French Vanilla Latte — the same real cream and brown-sugar-style custard method as our Standard French Vanilla Syrup, with a monk fruit/allulose sweetener standing in for both the granulated and brown sugar. The cream is what carries the actual “French Vanilla” character (see why this differs from Plain and Blonde Vanilla) — swapping the sugar doesn’t touch that.

The Syrup

Combine 3/4 cup water, 3/4 cup granulated monk fruit or allulose sweetener, and 1/4 cup brown-sugar-style monk fruit/allulose blend in a small saucepan over medium heat, stirring until fully dissolved — this can take a little longer than sugar. Stir in 3 tbsp heavy cream or half-and-half and bring to a gentle simmer for 3-4 minutes, same as the Standard version — this short simmer with the cream in the pan is what builds the custard body. Off the heat, stir in 2 tbsp pure vanilla extract (plus a pinch of turmeric for color, if using) and let it cool completely.

Store the finished syrup in a sealed jar in the fridge for up to 5-7 days. It makes roughly 10 drinks’ worth at 2 tbsp per serving.

Assumptions: monk fruit/allulose sweetener (both the granulated and brown-sugar-style blends) at typical grocery pricing (~$3/cup at bulk-bag pricing, same as our regular Sugar-Free Vanilla Syrup), a few tablespoons of half-and-half, and Costco-size pure vanilla extract. The sweetener swap is the bigger cost driver here than in the Standard version, since monk fruit/allulose runs pricier per cup than table sugar.

Storage & Shelf Life

• Keeps about 5-7 days in a sealed jar in the fridge — same shorter window as the Standard French Vanilla syrup, because of the real cream. Our other Sugar-Free syrups (no dairy) keep 2 weeks; this one doesn’t, and we’re not going to round that up.
• Crystallizing in the fridge? Some sweetener blends crystallize faster than sugar — gently reheat the jar in a warm water bath to re-dissolve before using.
• Give it a shake or stir before using; some settling is normal.

Sweetener Notes

• Monk fruit or allulose blends measure roughly cup-for-cup like sugar and behave most like it here — the easiest substitution if this is your first sugar-free syrup.
• Brown-sugar-style blends (several monk fruit/allulose brands make one) are what keep the flavor closer to the Standard syrup’s brown-sugar depth instead of tasting flatter.
• Real cream is still doing the custard work in this version — the sweetener swap only changes the sugar content, not the flavor profile that makes this “French Vanilla” instead of plain vanilla.

What to Make With This

2 tbsp of this syrup, stirred into hot espresso before adding milk, is the Sugar-Free French Vanilla Latte. If sugar content isn’t your main concern, the French Vanilla Syrup (Standard) uses the same method with regular sugar, or the French Vanilla-Maple Syrup behind our Clean-Ingredient tier swaps in real maple syrup instead.

FAQ

Does this taste as rich as the Standard French Vanilla syrup?

Very close — the cream and the cooking method are identical, and that’s what carries most of the custard character. The sugar swap changes sweetness and total sugar, not the underlying flavor profile.

Why does this still contain cream if it’s the sugar-free version?

“Sugar-free” here means the sweetener, not every ingredient. The real cream is what makes this recipe French Vanilla instead of plain vanilla — cutting it would just give you a sugar-free plain Vanilla Syrup with extra steps. See our Vanilla Syrup if that’s actually what you want.

Do I need to make this every time I want a latte?

No — one batch covers about 10 drinks over 5-7 days. The Sugar-Free French Vanilla Latte recipe assumes you already have a jar on hand.
