What You Need to Know Before Starting

Marshmallows are a controlled foam. Sugar provides sweetness and stability. Gelatin provides structure. Whipping introduces air, which sets as the mixture cools. Temperature accuracy and timing matter more than technique. If you can measure, heat, and whip, you can make marshmallows successfully.

Homemade marshmallows are softer and cleaner tasting than store bought versions because they contain no preservatives or stabilizers. They set at room temperature and do not require baking.

This process takes about 30 minutes of active work and several hours of resting time.

Ingredients You Will Need

Base Ingredients

• Unflavored powdered gelatin. This is the structural backbone. Use standard grocery store gelatin, not flavored gelatin.

• Cold water. Used both to bloom the gelatin and to dissolve the sugar.

• Granulated sugar. Provides sweetness and bulk.

• Light corn syrup or glucose syrup. Prevents crystallization and improves texture. Do not skip this.

• Fine salt. Balances sweetness.

• Vanilla extract. Classic marshmallow flavor.

Optional Add Ins

• Cocoa powder for chocolate marshmallows

• Peppermint extract, almond extract, or fruit extracts

• Food coloring

• Toasted coconut, cocoa powder, or freeze dried fruit powder for coating

Equipment You Will Need

• Stand mixer with whisk attachment or a strong hand mixer

• Medium heavy bottom saucepan

• Candy thermometer capable of reading up to 250°F

• 9 x 13 inch baking pan

• Parchment paper or non stick spray

• Silicone spatula

• Fine mesh sieve for dusting sugar

• Sharp knife or pizza cutter

Ingredient Measurements

• 3 packets unflavored gelatin or 21 grams

• 1 cup cold water, divided

• 1 1/2 cups granulated sugar

• 1 cup light corn syrup

• 1/4 teaspoon salt

• 1 tablespoon vanilla extract

• 1/2 cup powdered sugar mixed with 1/2 cup cornstarch for dusting

Step by Step Marshmallow Method

Step 1: Prepare the Pan

Line a 9 x 13 inch pan with parchment paper, leaving overhang on all sides. Lightly coat with non stick spray. Dust the bottom and sides with the powdered sugar and cornstarch mixture.

Shake out excess.

This step prevents sticking and tearing later.

Step 2: Bloom the Gelatin

Pour 1/2 cup cold water into the bowl of your mixer. Sprinkle the gelatin evenly over the surface. Do not stir. Let it sit for 5 to 10 minutes until fully swollen and sponge like.

Blooming ensures the gelatin dissolves evenly when heated.

Step 3: Cook the Sugar Syrup

In the saucepan, combine:

• 1 1/2 cups sugar

• 1 cup corn syrup

• 1/2 cup water

• 1/4 teaspoon salt

Place over medium high heat. Stir only until the sugar dissolves, then stop stirring. Attach the candy thermometer.

Allow the mixture to boil until it reaches exactly 240°F. This is the soft ball stage. This usually takes 8 to 12 minutes.

Do not stir during boiling. Stirring can cause crystallization.

Step 4: Combine Syrup and Gelatin

With the mixer running on low speed, carefully and slowly pour the hot sugar syrup down the side of the bowl into the bloomed gelatin.

Once all the syrup is added, increase speed to medium and mix for about 1 minute until fully combined.

Step 5: Whip Until Thick and Fluffy

Increase mixer speed to high. Whip for 10 to 15 minutes.

The mixture is ready when it is:

• Thick and glossy

• Very fluffy

• Warm, not hot

• Able to hold soft peaks

Add vanilla extract during the final minute of whipping.

If adding coloring or extracts, add them now in small amounts.

Step 6: Pour and Set

Immediately scrape the marshmallow mixture into the prepared pan. Work quickly. Spread evenly with a lightly greased spatula.

Dust the top generously with the powdered sugar and cornstarch mixture.

Let the marshmallows set uncovered at room temperature for at least 4 hours, preferably overnight.

Do not refrigerate. Cold temperatures cause condensation and stickiness.

Step 7: Cut and Coat

Lift the marshmallow slab out of the pan using the parchment overhang. Place on a cutting surface.

Dust a knife or pizza cutter with powdered sugar mixture and cut into squares or shapes. Toss each piece lightly in the sugar mixture to coat all sides.

Shake off excess.

Storage and Shelf Life

• Store marshmallows in an airtight container at room temperature.

• They keep well for up to 2 weeks.

• Do not refrigerate or freeze.

Common Problems and Fixes

• Marshmallows too soft: Syrup did not reach 240°F

• Marshmallows grainy: Syrup was stirred during boiling or sugar crystallized

• Marshmallows sticky: Not enough dusting or exposed to humidity

• Marshmallows dense: Under whipped mixture

Final Result

Properly made marshmallows are pillowy, elastic, and clean tasting. They melt beautifully in hot chocolate, toast evenly, and outperform anything store bought in texture and flavor.

Tips for Perfect Marshmallows Every Time

• Use a reliable candy thermometer to avoid undercooking or burning the sugar syrup.

• Whip the mixture long enough to incorporate air, which creates the fluffy texture.

• Experiment with flavors like peppermint, chocolate, or citrus zest to make unique marshmallow recipes.

• Dust your cutting tools with powdered sugar to prevent sticking.

• If you want firmer marshmallows, add a little more gelatin.

  
  

Creative Marshmallow Recipes to Try

Once you master how to make homemade marshmallows, you can explore variations that suit your taste or occasion.

Chocolate Marshmallows

Add 2 tablespoons of cocoa powder to the gelatin bloom step. Whip as usual for a rich chocolate flavor.

Peppermint Marshmallows

Add 1 teaspoon of peppermint extract during the last minute of whipping. Sprinkle crushed candy canes on top before setting for a festive touch.

Fruit-Flavored Marshmallows

Replace some water with fruit juice like strawberry or orange. Use natural extracts or zest to enhance the flavor.

Spiced Marshmallows

Add cinnamon, nutmeg, or ginger powder to the sugar syrup for a warm, cozy flavor perfect for fall.

These variations show how versatile marshmallow recipes can be when you make them at home.

Storing and Using Your Homemade Marshmallows

Proper storage keeps your marshmallows fresh and fluffy. Store them in an airtight container at room temperature, away from heat and humidity. Avoid refrigeration, which can make marshmallows sticky or hard.

Use your homemade marshmallows in:

• Hot chocolate for a creamy, melty topping

• S’mores with graham crackers and chocolate

• Baking, such as marshmallow-topped brownies or cookies

• Gifts wrapped in cellophane tied with ribbons
