These sugar-free apple cider marshmallows taste like the first cold weekend of fall: crisp apples, warm cinnamon and a little cider-mill tang, all whipped into a pillowy, cloud-soft square. Drop one into a steaming mug of hot apple cider and it melts into a spiced, creamy cap that tastes like a farm-stand afternoon. Best of all, they’re keto and low carb, with no corn syrup and no sugar, and every square has a little bonus collagen.

These are built on my Vanilla Bean Sugar-Free Marshmallows, the foundation recipe for every flavor in this series. If you’ve already made my Sugar-Free Pumpkin Spice Marshmallows, this one will feel familiar. It’s even easier, because there’s no heavy purée to fold in.
Why You’ll Love These Apple Cider Marshmallows
- They taste like hot spiced apple cider. You get bright apple, cinnamon, nutmeg and a whisper of clove, with a tangy cider finish.
- They’re keto and low carb. The secret is zero-carb apple cinnamon tea and apple extract instead of sugary cider. Allulose sweetens them without spiking your blood sugar.
- They have a little protein. Gelatin and collagen give every square a small protein boost.
- They’re easier than pumpkin spice. There’s no purée to fold in, so they set faster and stay extra fluffy.
- They’re the perfect fall gift. Tuck them in a jar with a cinnamon stick, and they make a sweet hostess, teacher or neighbor gift.
Tools You’ll Need
- Stand mixer with the whisk attachment

- Sharp knife or pizza cutter
How to Make Apple Cider Marshmallows
Step 1: Brew the Zero-Carb Apple Cider Base
Steep the 2 apple cinnamon tea bags in ½ cup boiling water for 10 minutes for a strong, double-brewed tea. Squeeze out the bags and chill the tea until completely cold. You can pop it in the freezer for 15 minutes.
Stir in the apple extract and apple cider vinegar, then pour the mixture into your stand mixer bowl.
Step 2: Bloom the Gelatin
Sprinkle the gelatin evenly over the cold apple tea, then the collagen. Stir once gently and let it sit for 10 minutes until it’s thick and spongy.
Make sure the tea is truly cold. Warm liquid stops gelatin from blooming properly, and that’s the number one reason marshmallows don’t set.
Step 3: Cook the Allulose Syrup
In a saucepan over medium heat, combine the allulose, ¼ cup water and salt. Stir until dissolved, then stop stirring and let it bubble until it reaches 235–240°F.
Watch it closely. Allulose browns faster than sugar. A pale golden tint gives these a lovely caramel-apple note, but pull it before it turns amber.
Step 4: Whip Until Fluffy
Turn the mixer on low. Slowly pour the hot syrup down the side of the bowl into the bloomed gelatin. Increase to high and whip for 8–10 minutes, until the mixture is thick, glossy, bright white and nearly tripled in volume.
Step 5: Add the Mulling Spices
Reduce the speed to low. Add the cinnamon, nutmeg, cloves and vanilla, and mix for 20–30 seconds until they’re just combined. Taste and add monk fruit drops if you like it sweeter.
For a pretty swirled look, mix only about 10 seconds so you get cinnamon ribbons running through the fluff.
Step 6: Pour and Set
Scrape the fluff into the parchment-lined pan with a greased spatula and smooth the top. Let it set uncovered at room temperature for 4–6 hours or overnight. Don’t refrigerate it.
Step 7: Cut and Dust
Whisk the dusting ingredients together. Dust the top of the slab, flip it onto a cutting board, peel off the parchment and dust the other side. Cut into 16 squares, re-dusting your knife or pizza cutter between cuts. Toss each square in the remaining dust.
Tips for Perfect Sugar-Free Apple Cider Marshmallows
Want a stronger apple flavor? Add an extra ½ teaspoon of apple extract in Step 1. Don’t add more vinegar, though. A little goes a long way.
Too sticky? Allulose pulls moisture from the air. Whip 1–2 minutes longer, let the marshmallows set fully, and store them with an extra dusting. On humid days, add another ½ teaspoon of arrowroot to the dusting blend.
Didn’t set? Either the tea wasn’t cold enough for the gelatin to bloom, or the syrup didn’t reach 235°F. A thermometer is your best friend here.
Grainy texture? Use allulose for the syrup. Erythritol recrystallizes and turns grainy. Save it for dusting only.
Spices sinking to the bottom? Add them at the very end on low speed, after the fluff is fully whipped. A thick fluff holds them in place.
Want caramel apple marshmallows? Drizzle the set slab with sugar-free caramel sauce before cutting, and sprinkle on chopped toasted pecans.

Bonus: Keto Hot Spiced Apple Cider (Mock Cider) to Float Them On
Real apple cider packs about 28g of carbs per cup. This cozy keto version gives you the same mulled, apple-forward comfort for nearly zero. It makes one mug.
- Steep 2 apple cinnamon tea bags in 1 cup boiling water for 5–7 minutes, then remove the bags.
- Stir in ¼ teaspoon apple extract, ½ teaspoon apple cider vinegar, 1–2 teaspoons allulose and a pinch of nutmeg.
- Add a cinnamon stick and a strip of orange peel, and let it sit for 2 minutes.
- Top with 2–3 apple cider marshmallows and watch them melt into a spiced, foamy cap.
For a slow-cooker party batch, multiply by 8, add 3 cinnamon sticks, 6 whole cloves and 2 star anise, and keep it on low for guests.
How to Store Homemade Sugar-Free Marshmallows
- Room temperature: 4–5 days in an airtight container with extra dusting powder and parchment between the layers.
- Refrigerator: Up to 1 week. Let them sit out for 10 minutes before serving.
- Freezer: Up to 2 months. Freeze them in a single layer first, then transfer to a freezer bag.
Nutrition Notes (Approximate, Per Marshmallow, Makes 16)
- Net carbs: under 0.5 g (allulose is not counted as a net carb)
- Protein: about 1.5–2 g from the gelatin and collagen
- Calories: about 10
- Sugar: 0 g added
These numbers are for the tea version. The real-cider option adds roughly 0.1 g net carb per marshmallow.
Apple Cider Marshmallow FAQ
Can I use real apple cider instead of tea?
You can swap in up to 2 tablespoons and keep these low carb. Using all cider would add about 14g of carbs to the batch and make the marshmallows softer and stickier.
Will I taste the apple cider vinegar?
No. At ½ teaspoon, it reads as a bright, fresh-cider tang, not vinegar.
Can I make my own apple pie spice?
Yes. Mix 2 tablespoons cinnamon, 1 teaspoon nutmeg, ½ teaspoon allspice and ¼ teaspoon cloves. Store it in a spice jar.
Can I skip the collagen?
Yes. They’ll be slightly firmer, but the recipe works with gelatin alone.
Can I use erythritol instead of allulose?
Not for the syrup, because it recrystallizes and turns grainy. It’s fine for dusting.
Are these keto?
Yes. Made as written, each marshmallow has well under 1g net carb.
