Ingredients You’ll Need
- 3 envelopes unflavored gelatin (about 7 g each)
- ½ cup cold water (for gelatin)
- 2 cups granulated sugar
- ¾ cup light corn syrup
- ¼ cup water
- ¼ teaspoon salt
- 1 tablespoon pure vanilla extract
- ½ cup powdered sugar
- ½ cup cornstarch
Step-By-Step Instructions
- Prepare the pan
Grease a 9×9-inch baking dish and dust it with a mix of powdered sugar and cornstarch. This keeps the marshmallows from sticking. - Bloom the gelatin
In the bowl of a stand mixer, combine gelatin and ½ cup cold water. Let it sit while you make the syrup—it will absorb the water and bloom. - Cook the syrup
In a saucepan, combine sugar, corn syrup, ¼ cup water, and salt. Heat over medium-high until the mixture reaches 240°F (soft-ball stage) on a candy thermometer. - Whip it up
Carefully pour the hot syrup into the gelatin mixture while the mixer runs on low. Once combined, increase to high speed and whip for 8–10 minutes until the mixture is thick, glossy, and tripled in volume. - Flavor and spread
Add vanilla extract, then immediately pour the mixture into your prepared pan. Smooth the top with a greased spatula. - Set and cut
Let the marshmallows rest at room temperature for at least 4 hours (or overnight). Dust a cutting board with powdered sugar/cornstarch, turn out the marshmallow slab, and cut into squares. Toss pieces in more sugar/cornstarch to prevent sticking.
Helpful Notes & Tips
- Use a candy thermometer: It ensures the sugar syrup hits the perfect stage for fluffy marshmallows.
- Storage: Keep in an airtight container at room temperature for up to 1 week. Do not refrigerate—humidity makes them sticky.
- Mess-free cutting: Use a lightly oiled knife or pizza cutter for clean cuts.
Recipe Variations
- Flavored Marshmallows: Add peppermint extract, almond extract, or even cocoa powder for fun twists.
- Colored Marshmallows: Stir in a drop or two of food coloring while whipping to match holidays or parties.
- Marshmallow Pops: Skewer cubes, dip them in chocolate, and sprinkle with crushed graham crackers for a s’mores vibe.
Serving Suggestions
- Drop into hot cocoa for the ultimate cozy drink.
- Use in Rice Krispies treats for a homemade upgrade.
- Toast over a campfire (just like the Stay Puft Marshmallow Man would want).
- Serve at a Ghostbusters-themed party with spooky snacks.
