Why Choose a No-Bake Dessert?
Baking can be rewarding, but it often requires time, precision, and heat. That’s where no-bake desserts come in to save the day. They’re:
- Quick and convenient

- Great for beginner cooks
- Fun for kids to help with

Ingredients That Make It Irresistible
This slice comes together with a handful of simple ingredients that pack flavor and texture. Here’s what you’ll need:
- 3 cups mini marshmallows – Light, fluffy, and sweet
- 1½ cups crushed biscuits or graham crackers – For a firm base with a bit of crunch
- ½ cup sweetened condensed milk – Adds richness and binds everything together
- ½ cup desiccated coconut – Gives a light tropical flavor and texture
- ½ cup colorful candy-coated chocolates (like M&Ms) – Adds crunch and color
- ¼ cup unsalted melted butter – Provides structure and smoothness
- 1 tsp vanilla extract – Enhances the overall flavor
- Optional: extra coconut or sprinkles for topping
All of these items can be found in a basic grocery store. You can also substitute or add ingredients depending on your flavor preferences.
Step-by-Step: How to Make No-Bake Marshmallow Slice
Step 1: Prepare Your Tin
Line an 8x8 inch square baking tray with parchment paper. Make sure to leave enough overhang on the sides. This makes removing and slicing much easier once it sets.
Step 2: Crush the Biscuits
Place the digestive biscuits or graham crackers in a sealed plastic bag. Use a rolling pin to crush them into small crumbs, but not powder. You want a bit of texture.
Step 3: Combine the Dry Ingredients
In a large mixing bowl, stir together the crushed biscuits, desiccated coconut, and candy-coated chocolates. These ingredients create a crunchy base for the soft marshmallows.
Step 4: Add the Wet Ingredients
Melt the butter and add it to the dry mixture along with sweetened condensed milk and vanilla extract. Stir until well combined and sticky.
Step 5: Fold in the Marshmallows
Gently fold in the mini marshmallows last. You want them to keep their shape, so stir just enough to distribute them evenly.
Step 6: Press Into the Tray
Spoon the mixture into your prepared tin and press it down firmly using the back of a spoon or clean hands. Ensure the surface is even and tight.
Step 7: Optional Topping
For an extra festive touch, sprinkle shredded coconut, mini chocolate chips, or colorful sprinkles on top. Lightly press them into the mixture so they stick.
Step 8: Chill to Set
Place the tray in the refrigerator for at least two hours. This step is essential. It allows the slice to firm up and makes cutting easier.
Step 9: Slice and Serve
Once set, lift the slab from the tray using the parchment paper. Slice into small squares or bars using a sharp knife. Store leftovers in an airtight container in the fridge.
Taste and Texture: What to Expect
This no-bake marshmallow slice is sweet, slightly chewy, and beautifully soft with just enough crunch to keep it interesting. The marshmallows give it a fluffy bite, while the biscuit base holds it all together. The pops of color from chocolate candies make it not only delicious but visually fun, especially for kids.
Each bite delivers a delightful combination of textures—creamy, crunchy, chewy—and flavors, from buttery richness to coconut sweetness. It’s a layered sensation without the layers of effort.
Variations to Keep It Interesting
One of the best things about this recipe is its versatility. You can swap out or add ingredients to suit different tastes or occasions.
1. Chocolate Lover’s Slice
- Add ½ cup melted milk or dark chocolate to the mix.
- Drizzle additional chocolate on top before refrigerating.
2. Fruity Marshmallow Slice
- Add chopped dried fruits like apricots, raisins, or cranberries.
- Use fruity-flavored marshmallows for a fun twist.
3. Nutty Delight
- Mix in chopped almonds, walnuts, or pecans.
- Peanut butter chips or a swirl of peanut butter also work well.
4. Holiday-Themed Slices
- Use red and green candies for Christmas.
- Pastel chocolates for Easter.
- Orange and black sprinkles for Halloween.
The options are limitless, and you can make this slice fit any celebration.
Helpful Tips for Success
- Use fresh marshmallows – Old ones get sticky and hard to work with.
- Don’t skip chilling – The slice won’t hold together properly without enough fridge time.
- Cut with a hot knife – Dip your knife in hot water and wipe it dry before slicing for cleaner cuts.
- Adjust sweetness – If you prefer a less sweet version, reduce the condensed milk slightly or use semi-sweet chocolate.
