- Max Mallow marshmallows for authentic marshmallow flavor (sans refined sugar or corn syrup)
- Coconut sugar for rich caramel-like sweetness
- Pure vanilla extract for warmth and depth
- Sea salt to balance the sweetness
- Water to create the perfect pourable syrup
The result is a homemade coffee syrup that’s rich, flavorful, and made with ingredients you can actually recognize.

How to Make Paleo toasted marshmallow Coffee Syrup
Step 1: make the syrup base
Add the water & coconut sugar to a small saucepan. Heat over medium-low heat, bringing to a simmer. Stir frequently, letting it simmer for about 5 minutes until all the sugar is dissolved.
Step 2: Add the flavor!
Turn the heat to very low and add the marshmallows. Stir well until they’ve completely melted into the syrup. Then stir in the vanilla and pinch of sea salt. Whisk until smooth and glossy.
Step 3: Cool
Allow the syrup to cool for several minutes. It will continue to thicken slightly as it cools. Transfer to a glass jar or bottle and refrigerate.

Toasted Marshmallow Coffee Syrup (Refined sugar-free!)
Ingredients
- 1 cup water
- 1 cup coconut sugar *you can sub 1/2 granulated monk fruit for a lower sugar option!
- 12 Max Mallow Marshmallows (I used the burnt caramel flavor) *You can sub regular marshmallows but i'd reduce it to 8 as they're typically larger than the ones I use.
- 1 tsp vanilla bean paste or vanilla extract
- small pinch of sea salt
Instructions
- Just a note: i'd consider 1-2 tbsp a "serving size"! You can always add more to a drink if you'd like!
- Add the water & coconut sugar to a small saucepan. Heat over medium-low heat, bringing to a simmer. Stir frequently, letting it simmer for about 5 minutes until all the sugar is dissolved.
- Turn the heat to very low and add the marshmallows. Stir well until they’ve completely melted into the syrup. Then stir in the vanilla and pinch of sea salt. Whisk until smooth and glossy.
- Allow the syrup to cool for several minutes. It will continue to thicken slightly as it cools. Transfer to a glass jar or bottle and refrigerate (glass is important so you can easily reheat it when using!).
- This syrup will thicken, so before use, heat it gently in the microwave before using. Alternatively, you can store it in a mason jar, scoop some of the firmed sauce into a jar, and pour the hot espresso shots over top of it!
