Ingredients & Why They Matter

Every ingredient plays an important role in creating this dreamy drink:

Frappe Base Ingredients:

1 cup cold milk (dairy or non-dairy)
Whole milk makes it creamiest; almond or oat milk work great too. For extra flavor, try vanilla almond milk.

1/2 cup vanilla ice cream or marshmallow-flavored ice cream
Marshmallow ice cream intensifies the flavor, but vanilla works perfectly too.

1/2 cup ice
Gives that perfect frappe thickness. More ice = thicker drink.

1/4 cup mini marshmallows
The star of the show! These melt slightly when blended for authentic flavor.

1 tablespoon marshmallow syrup or sweetened condensed milk
Syrup gives stronger marshmallow taste; condensed milk adds creaminess.

Food coloring in pastel pink, blue, yellow, and purple (optional)
For those gorgeous rainbow swirls. Gel food coloring works best.

Toppings:

Whipped cream
Essential for that cloud-like experience.

Mini marshmallows
Adds texture and reinforces the marshmallow flavor.

Rainbow sprinkles or cereal marshmallows
Because everything’s better with rainbow colors!

Cotton candy bits or edible glitter
For extra magic and sparkle.

Step-by-Step Instructions (With All My Best Tips!)

Step 1: Blend the Base

1. Add milk, ice cream, ice, marshmallows, and syrup to your blender
2. Blend on medium until smooth and fluffy (about 30-45 seconds)
3. Check consistency – it should be thick but pourable
4. If too thick, add milk 1 tablespoon at a time
5. If too thin, add more ice a handful at a time

Pro Tip: Don’t overblend or the marshmallows can make it gummy. Pulse if needed.

Step 2: Create Rainbow Swirls (Optional but Gorgeous)

For those Instagram-worthy pastel layers:

1. Divide mixture evenly into 4 small bowls
2. Add a drop of different food coloring to each
3. Gently pour or spoon colors alternately into glasses
4. Use a straw to make one gentle swirl (don’t overmix!)

Color Tip: Less is more with food coloring – you can always add more.

Step 3: Add the Finishing Touches

Here’s where the magic happens:

1. Top with a generous swirl of whipped cream
2. Sprinkle with mini marshmallows
3. Add rainbow sprinkles or cereal marshmallows
4. Dust with edible glitter or cotton candy bits
5. Insert a fun wide straw and enjoy immediately!

Presentation Tip: Rim the glass with frosting and dip in sprinkles for extra flair.
