This easy Marshmallow Fondant recipe makes smooth, soft, and pliable fondant that’s perfect for covering cakes or creating decorative shapes. It’s inexpensive, tastes great, and requires only a few simple ingredients a must-try for beginner and experienced bakers alike!

Ingredients
- 1 (16-ounce) package mini marshmallows (about 8½ cups)
- 2–5 tablespoons water
- 8 cups powdered sugar (confectioners’ sugar), divided
- ⅓ cup vegetable shortening
Instructions
- Melt the marshmallows:
Place the mini marshmallows and 2 tablespoons of water in a large microwave-safe bowl. Microwave on high for 30 seconds, then stir until partially melted. Continue microwaving in 30-second intervals, stirring between each, until smooth and fully melted. - Add sugar:
Add about 5 cups of powdered sugar to the melted marshmallows. Using a greased spatula or spoon, gently fold the sugar into the mixture until it starts to come together. - Prepare your surface:
Generously grease your hands and countertop with vegetable shortening to prevent sticking. - Knead the fondant:
Turn the marshmallow mixture out onto the greased surface. Begin kneading it as you would bread dough, gradually adding more powdered sugar as needed. Continue kneading until it forms a smooth, elastic ball that’s firm but still pliable. - Adjust texture if needed:
If the fondant feels too dry or starts to tear, add a small amount of water (½ tablespoon at a time) and knead again until soft and stretchy. - Store or use:
Wrap the fondant tightly in plastic wrap, then place it in an airtight container. Let it rest at room temperature for at least 30 minutes before using.

- Use a stand mixer: If preferred, you can use a dough hook to knead the fondant — just make sure to grease the bowl and hook.
- Rest before use: Letting the fondant sit for 30–60 minutes makes it easier to roll out and shape.
- For coloring: Add gel food coloring after kneading and mix until evenly blended.
Variations and Substitutions
- Flavored fondant: Mix in extracts like vanilla, almond, or lemon for extra flavor.
- Colored fondant: Use gel food colors (not liquid) for vibrant shades without changing texture.
- Chocolate fondant: Replace ½ cup of powdered sugar with unsweetened cocoa powder.
- Vegan version: Use vegan marshmallows and vegetable shortening.
