Soft Fluffy Homemade Marshmallows

The first time I made homemade marshmallows, I stood in my kitchen watching this transformation that felt like pure magic. One minute I had liquid syrup and water, the next I had this glossy white cloud that was growing bigger and bigger in my mixer bowl. I couldnt stop laughing because it looked like something out of a science experiment, but my whole apartment already smelled like a carnival.

I made these for a winter weekend gathering with friends, and honestly, they were the star of the show. We set up a mini hot chocolate bar, and watching everyones faces when they took their first sip with that slowly melting homemade marshmallow on top was unforgettable. Someone actually asked if I could make them for their wedding favors.

Ingredients

• 2 cups granulated sugar: This provides the structure and sweetness that creates that perfect marshmallow texture
• 1/2 cup light corn syrup: Keeps the sugar from crystallizing and gives marshmallows their characteristic chew
• 1/2 cup water: Helps dissolve everything into a smooth syrup
• 1/4 tsp fine sea salt: Balances all that sweetness so it doesnt feel cloying
• 3 envelopes unflavored gelatin: This is what creates that amazing fluffy texture and structure
• 1/2 cup cold water: Cold water is essential for properly blooming the gelatin
• 1 tbsp pure vanilla extract: Add this in the last minute for that classic marshmallow flavor
• 1/2 cup confectioners sugar: For coating and preventing that sticky situation
• 1/2 cup cornstarch: Mix this with powdered sugar for the perfect non stick dusting

Instructions

Prepare your pan:

Lightly grease a 9x9 inch pan and dust it with a mixture of equal parts confectioners sugar and cornstarch, saving the rest for later

Bloom the gelatin:

In your stand mixer bowl, combine the gelatin with 1/2 cup cold water and let it soften while you work on the syrup

Make the sugar syrup:

Combine granulated sugar, corn syrup, the other 1/2 cup water, and salt in a saucepan, stir until dissolved, then boil to 240°F without stirring

Create the magic:

With mixer on low, carefully pour that hot syrup into the gelatin, then gradually increase to high and whip for 10 to 12 minutes until its thick and tripled in volume

Add flavor and set:

Beat in vanilla during the last minute, spread quickly into your prepared pan, dust the top with more sugar mixture, and let it sit for at least 4 hours

Cut and coat:

Turn the slab onto a cutting board, cut into squares with a knife dusted in the sugar mixture, and toss each piece until fully coated

These have become my go to gift during the holiday season, wrapped in little cellophane bags with ribbons. Theres something so special about handing someone something you made from scratch that feels so fancy and playful at the same time.

Getting Creative With Flavors

While vanilla is classic, Ive discovered that peppermint extract makes the most incredible holiday marshmallows. You can swirl in food coloring during that final minute of mixing to create gorgeous marbled effects that look stunning in gift bags.

The Setting Game

Patience really pays off here, and letting them set overnight gives you the cleanest cuts and best texture. The difference between a four hour set and an overnight one is noticeable in how well they hold their shape.

Storage Secrets

These will stay fresh in an airtight container for about a week, though they rarely last that long in my house. Keep them in a cool, dry place away from moisture or theyll start getting sticky again.

• Layer them between wax paper if storing multiple pieces
• A piece of white bread in the container helps keep them soft
• They freeze surprisingly well for up to a month

Theres something so satisfying about making something from scratch that most people only buy in bags. These marshmallows have a way of making everyday moments feel a little more special.

Your Recipe Questions

→ How long do homemade marshmallows take to set?

Allow marshmallows to set at room temperature for at least 4 hours, though overnight is preferable. This ensures the structure fully stabilizes and achieves the perfect fluffy-yet-firm texture. Cover the pan only after completely set to prevent moisture absorption.

→ Can I make marshmallows without a stand mixer?

A stand mixer with whisk attachment is highly recommended because the mixture requires 10-12 minutes of continuous high-speed beating to triple in volume. Hand mixers may work but risk overheating. The vigorous whipping incorporates the air necessary for the characteristic fluffy texture.

→ What's the purpose of the cornstarch coating?

The combination of confectioners sugar and cornstarch prevents the sticky marshmallow pieces from adhering to each other or the cutting surface. Cornstarch absorbs moisture while sugar provides a smooth, sweet finish. Always dust your knife and hands with this mixture when cutting.

→ Why must the sugar syrup reach exactly 240°F?

240°F (115°C) is the soft-ball stage in candy making, which creates the proper concentration of sugar for stable marshmallows. Lower temperatures result in sticky, soft confections that won't hold their shape. Higher temperatures produce hard, dense marshmallows lacking the signature airy texture.

→ How should I store homemade marshmallows?

Store in an airtight container at room temperature for up to one week. Avoid refrigeration as moisture causes them to become sticky and lose texture. Layer between parchment paper if stacking, and keep away from humidity or direct sunlight which can affect consistency.

→ Can I substitute gelatin for a vegetarian option?

Traditional marshmallows require gelatin for structure, making them unsuitable for vegetarians and vegans. Agar-agar can be attempted as a substitute but produces significantly different texture and results. For authentic fluffy marshmallows, unflavored gelatin remains essential.
