Ingredients

• 1 tablespoon Unflavored gelatin
• 3 tablespoons Cold water
• 1 cup Granulated sugar
• 1 cup Light corn syrup
• 1 cup Water (for sugar syrup)
• 1 teaspoon Vanilla extract
• 0.5 teaspoon Salt
• 1 tablespoon Unsalted butter (for greasing)
• 6 cups Rice Krispies cereal

Directions

Step 1

Start by preparing the homemade marshmallows. In a small bowl, combine the unflavored gelatin and 3 tablespoons of cold water. Let it sit for 5 minutes to bloom.

Step 2

In a medium saucepan, combine granulated sugar, light corn syrup, and 1 cup of water. Place over medium heat and stir gently until the sugar dissolves.

Step 3

Increase the heat to medium-high and bring the mixture to a boil, cooking until it reaches 240°F (soft ball stage) on a candy thermometer. Remove from heat.

Step 4

Transfer the bloomed gelatin to a stand mixer fitted with the whisk attachment. Carefully pour the hot sugar syrup into the mixer bowl in a thin stream while the mixer is running on low speed.

Step 5

Gradually increase the speed to high and beat for 10-12 minutes, or until the mixture becomes thick, glossy, and begins to cool. Add the vanilla extract and salt, then beat until fully combined.

Step 6

Grease a large mixing bowl lightly with unsalted butter and pour the homemade marshmallow mixture into the bowl.

Step 7

Stir in the Rice Krispies cereal a little at a time, folding gently with a silicone spatula until the cereal is evenly coated with marshmallow.

Step 8

Lightly grease a 9x13-inch baking pan with unsalted butter. Spread the Rice Krispies mixture evenly into the pan, pressing gently with buttered hands or a greased spatula to ensure an even layer.

Step 9

Let the treats cool completely at room temperature for about 1 hour, or until firm.

Step 10

Once set, use a sharp buttered knife to cut into 16 squares. Serve and enjoy!
